Everything you need to know about MacBooks & Heat

What is this page about?

.

This page, as the title implies, contains everything you need to know about MacBooks and heat. It may seem an unusual topic, but being very compact, MacBooks (MacBook Pros & MacBook Airs) can get extremely hot. Sometimes the heat produced is normal, however sometimes it is damaging to both the components of your Mac and your health. On this page you can find out where on your Mac to expect heat, how hot is too hot, how to keep your Mac cool and how to protect yourself from heat radiation.

How hot does your Mac get? 169 comments

My 13" MacBook Pro stays pretty cool ;-) Except when I watch flash videos on YouTube or play games (such as Half Life 2), then it can get up to 100C. I probably should use SMC fan control to cool it down when I'm playing games, but I'm too lazy...hehe.

Very interesting point about the different running temperatures of different types of computer. My Macbook gets fairly hot, but I'm fine as long as I have jeans on.


TravelingRae 5 years ago

At one point, I was at something like 89 degrees C! It was scorching! I installed the Fan Control utility and that has improved things greatly.

tropicalmonsoon1 5 years ago Author

@TravelingRae: Yeah, mine has gotten up over 100C!


Lindrus 5 years ago

My Macbook Pro got up to 79 degrees C. Then I installed smcFanControl, and that helps a lot. Now I never have it run hotter than 60.


tompatricka 5 years ago

Being a Mac data recovery specialist I often receives cases where huge data loss occurs due to disk damaged by bad temperatures. Most of the users are unaware of the temperature limit suitable for their Macs. Like you mention Laptop cooling pads are one of the best ways to bring down the temperature and save the life of hard disk and other vital components. Every Mac user must read your lens which shares very useful information about the issues generated by overheating of Mac & its components.


anonymous 5 years ago

My 27" iMac only gets up to 50C on full load...The Macbook air on the other hand..........96C lol


tropicalmonsoon1 profile image

tropicalmonsoon1 5 years ago Author

@tompatricka: Yes, however as long as you back up your important data the failure of a hard disk isn't too serious. Hard disks are cheap to replace, at about $100.

tropicalmonsoon1 4 years ago Author

@anonymous: Remember that all the temps in this lens are in celsius, not fahrenheit, so you may have gotten confused. The temps that you've listed are perfectly normal. In fact, your Mac is running cooler than most do!

mines at 167..... is that normal?


tropicalmonsoon1 profile image

tropicalmonsoon1 4 years ago Author

@anonymous: 167F (75C) certainly isn't overheating, and you shouldn't be too worried about it. However, what tasks are you performing on your mac when it reaches that temperature? Because if it is 75C when idling or browsing the web or doing other non intensive tasks then I'd say the temp is a bit high, and that it might pay to invest in a laptop cooling pad... Oh, and remember to state all temps in C, not F. Thanks!


anonymous 4 years ago

It sits at 75c when idle and can range all the way up to 95c, when I installed smcFanControl, it said my fan wasn't running at all

@anonymous: Hi there, can I ask what sort of mac you are using?


anonymous 4 years ago

Mine goes up to 72 when on a Skype Video Call, my girlfriend's has gone up to 80 while both Skype-ing and Youtubing. I haven't tried using both Skype and Youtube together but guessing it'll be about 80 as well. So is 80 alright? We Skype for hours at a time.


tropicalmonsoon1 profile image

tropicalmonsoon1 4 years ago Author

@anonymous: Yeah that temperature is fine for the Mac, however if it's a laptop and you have it on your lamp, the heat may cause discomfort during extended use. If it does, you could download smc fan control or, if it's a common scenario, perhaps purchase a laptop cooling pad (for more info about both things check out the rest of this page).

I'm using iStat and I don't know which temp should I stated as my macbook's temperature

Model: Macbook Pro Early 2011

Temp: HD - 44

CPU - 76

Enclosure Base - 38

Enclosure Base 2 - 38

Enclosure Base 3 - 38

Heatsink B - 51

Mem Bank A1 - 52

Mem Module A1 - 56

Fan: 6200 rpm

Previously my fan only spin at 1997 rpm but lately when I started downloading torrent, the fan is maintain at 6200 rpm. Is it normal?


tropicalmonsoon1 profile image

tropicalmonsoon1 4 years ago Author

@anonymous: Hi there Azam, you'd usually state the CPU temp as your Mac's general temp. So yours would be 76C. As for your second question, may I ask what your CPU temp is when your fan temp is at 6200rpm and you're downloading torrents?


anonymous 4 years ago

@tropicalmonsoon1: When downloading torrents, it ranges from 75 and 85. Maximum reading that I saw once was 94. If I stop torrenting, then it will goes down to 60 - 67.

p/s: there is no air that i can sense at the vent when the fan spins at 6200. Is it normal?


tropicalmonsoon1 profile image

tropicalmonsoon1 4 years ago Author

@anonymous: Yes, that is getting a bit too hot at 94C. Now, the reason you can't feel any air coming out of the vent may be because your Mac's vents are clogged up with dust & lint (check the bottom of this page for how to clean it out). If that fails to work, I'd consider purchasing a laptop cooling pad (scroll down this page a bit to find some good ones recommended by this site).

Right now, I'm doing "not much" - just browsing here as a matter of fact. My MacBook Air 1.8GHz i7 currently has a CPU temp of 56 deg C, yet the fan is running full blast (6500rpm). The case is hot to the touch. It's a mystery to me why the fan gets stuck at full speed and it's also a mystery why it feels hot to the touch, yet the CPU temperature (as well as all the other temperatures) is quite modest. I think a lot of people have this kind of an issue.


tropicalmonsoon1 profile image

tropicalmonsoon1 4 years ago Author

@anonymous: Hi Polarbreeze,

You've stumbled upon something I haven't covered here: When the fans behave erratically it is almost always because the SMC is messed up. SMC stands for System Management Controller and is in charge of low-level functions on your Mac, such as the fans. Fortunately it's possible to RESET the SMC, which will most likely fix any problems with it. To reset the SMC follow these steps (quoted from Apple Support Communities):

1.Shut down the computer.

2.Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.

3.On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.

4.Release all the keys and the power button at the same time.

5.Press the power button to turn on the computer.

Good luck, and be sure to come back if your problems persist!

Mine heats up to around 100C running any kind of high end game in win7 through bootcamp. I have smc set to full power, but it still overheats and goes into hibernation after about 30 minutes of gaming. Specifically it's the upper left side (near the escape button) that gets really hot.

I have a medio 2010 MacBook Pro.

@anonymous: Hi there Lilla,

I imagine that the upper left side of the computer would be where the graphics card is located, if it is getting very hot there when gaming - Do you use your MacBook Pro on your lap or on a desk, by the way?


anonymous 4 years ago

My little MacBook Pro gets really hot when I play high graphics games like Assassins Creed or MW3. I play for about ten to fifteen minutes before the internal fan starts sounding like a car engine and the upper half of the keyboard is really warm. After about a year of searching for the appropriate cooling system unsuccessfully, I finally decided that games just need to stay on the Xbox and off the MacBook. =/ It's not worth tearing up my beloved Mac.

However if you are consuming flash content, playing games, or doing something else that is intensive you should either use your MacBook Pro on a hard surface (desk, book) or place a laptop cooling pad under it (for more info on the latter scroll down to the laptop cooling pad section of this page.

I use my 2013 rmbp for work and have it connected to 3 external displays (all full HD) plus my retina display at its highest resolution setting. I'll have Parallels going with 8-12 jobs running in Windows while working on my other screens and watching Netflix pretty much nonstop 12 hours a day.

Clearly this isn't normal usage, but I became concerned by 100c + temps non stop and bought a cooling pad. That didn't seem to help too much although it did drop me into the 90's. My question is this: I get some relief if I turn up the fans using SMC fan control. I'll stay around 70c with the fans both at 4000 rpm. The noise is not a concern for me, but is there any downside to running the fans full blast most of the time? I figured it was the lesser of 2 evils....

@LuisMartins: Hi there,

70-80C is pretty normal for a MacBook Pro when you're preforming intensive tasks. Just make sure to use it on a hard, flat surface when you're doing so to allow for max airflow & cooling - And if the temp consistently gets over 90C then it might be a good idea to buy a laptop cooling pad to keep your Mac's temps down and thus extend it's lifespan. If you decide you want to get one, check out the "Laptop Cooling Pads" section of this page, as there's a few good ones listed there.

Hi I was wondering if a SSD in my macbook pro would help with the temperature mine usually runs at 45 ºC when browsing a normal pages. When i go to youtube or load up any game in general, or an application(Photoshop, iMovie, etc) it usual goes up to about 89ºC-98ºC. I was wondering if i could get a link to a cooling pad and have this question answered. Thanks

@anonymous: A SSD would cool down your Mac a bit, however it's a very expensive and inefficient option compared to a cooling pad. If you want a good laptop cooling pad, here's one from Amazon: http://www.amazon.com/gp/product/B002MU1ZRS/ref=as...

@tropicalmonsoon1: I was just wondering because and SSD would help with Load times and stuff correct?

@anonymous: Yeah, a SSD would make load times much faster. It's a great upgrade to speed your Mac up - just don't buy it just to cool it down, as the effect will be pretty minimal.

my mbp has gotten upwards of 90C so i understand everyone's concern. sooooo..... i made something to cool it down. it's better than a cooling pad because in essence those cooling pads are only a barrier between you and the mbp. please check it out we're currently running our campaign on kickstarter. we actually thought your page was so handy we link people to you. =) please go to kickstarter.com and search for 'Cool' Macbook Pro. Thanks!

    -------------Places on your Macintosh laptop where you should expect heat--------------

    ----Should you use your MacBook on the lap or the desk?----

    You may have been told by various people that having a laptop in direct contact with your lap is dangerous, that over a long period of time can cause cancer in the genital region or can render you infertile. While preforming basic tasks on your Mac while it's on your lap will be ok, preforming intensive tasks (those that make your Mac hot) on a regular basis while it's on your lap is not good for your health. On the lighter end it can cause fungal infections like thrush, over a long period of time it can render you infertile, and on the heavy end genital cancer can come of it. [For more information about the health effects of using a hot MacBook on your lap, visit Is it Harmful to use a Hot MacBook on your Lap?]

    To protect yourself from this dangerous heat radiation you should put something between you and your Mac, such as a cushion. Although soft objects like cushions protect you from heat radiation, they also act as an insulator for your MacBook, making it even hotter, shortening it's lifespan and causing you discomfort. The best way to stay safe from radiation while still being able to use your Mac on your lap is to use a laptop cooling pad (for more information about laptop cooling pads see below).

    NOTE: A little radiation comes from your Mac's screen, however it is a very small amount compared to CRT (these) displays. Modern LCD (these) displays emit a very low amount of radiation and it's not a threat.

    Laptop cooling pads

    For those of you who don't know what they are, laptop cooling pads are plastic or aluminium pads that can either sit between your MacBook and your lap, or your MacBook and a desk/table - Their purpose is to keep your MacBook running cooler, by both lifting the computer up to allow it 'breathing space', and sucking the hot air away from it with one or more fans. In addition to keeping your Mac cool, laptop cooling pads also keep you cool, as they separate you from your MacBook, and the heat it generates. So this does not only benefit your laptop's health, but also your own.

    Laptop cooling pads are generally powered by your MacBook's USB ports, and modern ones contain quiet but powerful fans that you shouldn't notice under everyday use. They are very cost effective, starting at only $2-$3 on Amazon, before shipping. Of course if you want a higher quality one, you'll have to pay a bit more - However even the high end cooling pads are affordable, their prices sitting at around $25-$30 US dollars. Below are three cooling pads available for purchase via Amazon in the US & Canada - The best one from each price range ($2, $10 & $30) has been selected, so check them out if you're looking at getting one!

    Laptop cooling pads ($2-$30)

    Laptop Notebook Cool Pad w/ 3 Fans
    Laptop Notebook Cool Pad w/ 3 Fans

    This laptop cooling pad is great value - For only $2 you can get a stylish cooling pad with three fans integrated. The normal price for this is $20, but amazon is currently selling it for only $2. You probably won't see such a good cooling pad for such a low price ever again, so if you want a cooling pad, buy this now!

     
    Belkin F5L001-BLK Laptop Cooling Pad (Black)
    Belkin F5L001-BLK Laptop Cooling Pad (Black)

    This cooling pad is quite affordable at only $18, and includes something that separates it from other cooling pads: Instead of sucking the hot air away from a laptop, it blows cool air at it. This concept hasn't been used before, but is apparently more efficient. Visit it's amazon page for more info.

    Note: This cooling pad can be used on the lap in addition to the desk!

     
    Targus Lap Chill Mat for Laptop, Silver/White Accents (AWE5504US)
    Targus Lap Chill Mat for Laptop, Silver/White Accents (AWE5504US)

    This laptop cooling pad is designed for use on the lap, so you you don't need to keep your MacBook tied to a desk to keep it cool. No external power is required; simply plug the cooling pad into a USB port on your laptop and enjoy the quiet by efficient cooling!

    Note: This cooling pad can be used on the lap in addition to the desk!

     

    Do laptop cooling pads actually work? What do you recommend?

    Yes!

    anonymous 3 years ago

    I don't think you NEED one, but they are nice to cool down your computer... It makes a better user experience.


    anonymous 3 years ago

    Yeah I reckon.

    Yeah, they work, I guess. But I don't like them.


    anonymous 3 years ago

    If u play games.


    anonymous 3 years ago

    Yes - Mine cools my MacBook Air down my 20-30C! The fan also makes me cooler, in the summer.


    anonymous 4 years ago

    Well, I don't use a cooling pad. I was at office depot and saw these things that literally are bouncy balls that divide in half, and you put them under you computer in the back, so you computer ends up being on a slant. These balls cost me 50c each and I personally think they are "cool" and effective!


    anonymous 4 years ago

    My Belkin works quite well :D


    anonymous 4 years ago

    Yeah, but so does a book hahahaa


    anonymous 4 years ago

    They work, although they are not necessary for most people...


    anonymous 4 years ago

    Hi, I Jamal

    I go to the hospital for three weeks after the purchase, I recommend using a pillow in your pillow and burned in the heat of everything for you to bring your case

    Jamal


    anonymous 4 years ago

    Well, I play Minecraft on my Macbook pro which I got on November 3, 2011. Whenever I play Minecraft it instantly goes from 185-210 degrees. I used the laptop cooling pad efficiently dropping it to a consistent 180-200(sometimes goes higher). So yeah it does work. I would recommend targus as it is reliable and efficient. But if your going to play games like Minecraft don't expect it to instantly go down below the 150s


    anonymous 4 years ago

    Yes. When my laptop gets hot to the touch from high cpu usage from doing things like a full virus scan or using an app with a lot of graphics... I turn on the cooling pad and it feels much cooler. I suppose it might be that the CPU may not be much cooler but at least the rest of the laptop is and so many of the components must also be cooler which means they will last longer. If you don't think they work, you either have a bad one or have not used one.


    anonymous 4 years ago

    I use the rain design one. Works great to keep the heat away from your legs and provides passive heat dissipation through it's aluminum construction.


    laetusviator lm 4 years ago

    I use a stand... not a cooling pad exactly, but because of the stand design there's extra airflow so my macbook runs cooler.


    anonymous 4 years ago

    they worked for me!


    anonymous 4 years ago

    In my experience they work great, especially in the summer time. Just make sure you don't get a cheap one (they're noisy as). Get one that costs about $20-$30 and it will be nice and quiet. I've got a Chill Mat (sorta like the one in the selection above) and it's quiet and works great! I'd recommend that one!


    anonymous 5 years ago

    I used a laptop cooling pad before and it lowered the temperature at least 7 degrees C. Unfortunately, it didn't last very long before it broke, so I guess it's more of a maybe then a yes.

      I think there is nothing you can do to prevent your laptops from overheating, because of the way they are built, that's why I want a normal desktop computer now :/


      anonymous 5 years ago

      I was given one, the Belkin, and I can see no difference in internal temperatures in my MBP late 2008 when it runs. But it does make noise, so it's nicer when it's unplugged.

        The Poor Man's Laptop Cooling Pad

        If you cannot buy a laptop cooling pad, either because you cannot afford one or because they are difficult to come by in your geographical area, there is an alternative. Desk fans, although they obviously won't work as well as a cooling pad, can be used as a substitute. Simply aim the desk fan at you & your MacBook, so that there is air flowing over the computer. This applies the same principal as a laptop cooling pad does, as it blows the hot air lingering around the laptop's case away, replacing it with fresh, cooler air. The breeze from a desk fan unfortunately cannot reach the underside of your MacBook, which is what makes it less effective than a cooling pad - However it can still cool your MacBook down significantly, so give it a try.

        -------------------------How hot is too hot?-------------------------

        A silly picture XD
        A silly picture XD

        MacBook Airs and MacBook Pros can get up to 105 degrees C (depending on the processor) before they automatically shut down. They shut down at that temperature to protect the processor from seriously damaging itself. It is recommend you keep your MacBook at 85C max if you want to extend its life as long as possible. If you're not too worried about that, but don't want to cause any serious damage, keep your MacBook under 100C. Running any computer processor above 90C will slowly damage it and shorten the life of the processor and possibly other components as well.

        ---------------------Free applications that can help keep your Mac cool---------------------

        SMC Fan Control displays your Mac's CPU temperature in real time on the top menu bar and allows you to adjust the internal fan speeds accordingly. SMC Fan Control should work with any intel Macintosh, and can be downloaded free of charge here.

        iStat Pro is another application, similar to SMC Fan Control, that allows you to monitor your Mac's temperature. And although iStat Pro doesn't allow you to change the speed of your Mac's fans, it shows much more detailed heat readings, such as the CPU heat, the hard disk(s) heat, the heat-sink heat and even the heat of your Mac's enclosure! iStat Pro can be downloaded free of charge here.

        Flash Content

        Flash content is the most common generator of intense heat in Macintosh computers by a long shot, as it unnecessarily taxes the CPUs, heating them up. Coupled with lazy developers and over-use on the internet, flash is by far the worst multimedia platform for Macs. Avoid it when possible.

        In-Browser FlashBlockers provide a simple but effective solution to flash's unavoidability on the internet: Every piece of flash content is replaced with a button that says Flash. If you want to view the content, simply click the button. However if you don't want to view that particular piece of flash content then the FlashBlocker will prevent the applet from running, thus saving CPU power.

        For Safari download Click2Flash here.

        For Google Chrome download FlashBlock here.

        For FireFox download FlashBlocker here.

        For many people YouTube is the main source of flash usage, and therefore heat, on their Mac. Up until recently all of YouTube's videos were powered by flash, however YouTube is now running a HTML5 BETA that anyone can opt into, wether they have a YouTube account or not. HTML5 is a modern alternative to flash, and while not yet developed enough to be able to play all of YouTube's videos, can play a large amount of them. So when you visit YouTube and watch a video, it will play in HTML5 if possible. While HTML5 still uses a significant amount of resources on your Mac, it preforms much more efficiently than Flash, thus reducing heat.

        You can opt into the YouTube HTML5 BETA here.

        MP4 videos are much more efficient than Flash Videos

        If you stream videos using video-streaming websites (for example, wtso.net, animefreak.tv etc) you may notice that your Mac heats up and becomes noisy while the videos are playing. This is because the online player used to play them is powered by Adobe Flash, which as we now know is not-good for your Mac in terms of heat and battery life. Fortunately however, it is possible to download videos off of almost any free streaming website to your MacBook's hard drive. It is completely free and legal to do so, and all you need to be able to carry it out is a modern version of Google Chrome (which can be freely downloaded here if you don't already have it).

        Once you have Google Chrome installed visit How to Download Online Videos to your Mac for a step-by-step tutorial on exactly how to do this.

        Flash might be great, but people are turning to HTML5 because they don't need it anymore. Anyway, the iPhone only knows HTML5, not flash. They should've worked on the 'hit features' rather than the 'flashiness'...

        anonymous 4 years ago

        One could argue that Flash wasn't even (well) designed for desktops either. The temps on a desktop go way up too with Flash.

        With all the focus on energy efficiency, I'm surprised some government agency hasn't inquired at Adobe about Flash's famed inefficiency. One machine running at full power doing Flash is bad, but multiply that by the millions of users across the world. I don't run Mac personally, but Steve Jobs was right to call out Flash. No one else had the guts to do it.

        HTML5 can't happen too fast, imo.


        Cdoimne 4 years ago

        I say yes however it is a very useful platform that is easy to use. Adobe is smart in making it and I respect flash apps and websites that are made and used correctly. However, flash is inefficient and can be VERY annoying when browsing. Those flashy animated ads and websites bug me, but it's a personal opinion. It could go either way but if there is an html/css/javascript/php/anything else alternative I'd opt to use that.

          anonymous 4 years ago

          as a developer i would say no flash will stick around until something better comes along, but saying that flash development is very big and isn't going to change overnight.


          anonymous 4 years ago

          You couldn't be more completely blind. Open your eyes, son... this has nothing to do with Flash as a plugin. It runs like crap because APPLE WANTS IT TO.

          Allowing Flash = No more appstore. This is strictly a money issue, a blind man could see that. It has nothing to do with poorly coded Flash, you run into that issue with any technology - JS, HTML, CSS, PHP, etc. Everything you have mentioned here is exactly what Jobs wants - and you are a sucker fanboy for believing any of it.

          As far as mac flash performance (from tomshardware.com):

          "Note that on the Mac side, Flash Player must rely on the Mac OS Video Decode Acceleration Framework to access hardware acceleration (included in Mac OS X 10.6.4 and later). This Mac OS framework does not support Intel GPUs, such as the GMA 950 and the new HD Graphics. The new MacBook Pros lean on the discrete Nvidia hardware for Flash-based H.264 decoding, which is supported by the Video Decode Acceleration Framework."

          There are a MILLION roadblock hassles in place for anyone developing for the mac outside of Apple - they have never played nice with anyone, they always take a ridiculous amount of control over everything they do and allow users to do things in a severely restricted sandbox without any other options for anyone.

          Apple as a company is going to fall, and fall hard - anything that runs like they do, and grows as fast as they do, with so many issues in plain sight with morality, business practices, restrictions, etc... I can't wait until they take a massive hit to PR and lose everything.

          tl:dr; Good fanboy! As if you read the script!

            Spotlight Indexing

            If you notice that your MacBook is getting up to temperatures of about 80C for seemingly no reason, it may be because spotlight is indexing. A spotlight index is a task that your Mac preforms from time to time, and occurs mainly after you have installed a new hard drive, reinstalled or upgraded the OS or have added a large volume of data to your hard drive.

            Indexing usually lasts several hours, and is preformed so that your hard disk can be searched more efficiently. Have a look at the spotlight icon (upper right hand corner of the screen). If there is a pulsating dot in the middle of the magnifying glass (as shown in screenshot above) spotlight is indexing on your Mac. Click on the spotlight icon to see how much longer the indexing is going to take. You should avoid performing intensive tasks on your Mac while spotlight is indexing, because performance will suffer and the computer will be prone to overheating. There are no known ways to stop spotlight from indexing.

            Heat whilst using external displays?

            You may notice that your MacBook heats up when you connect it to an external display (especially a large one). This is perfectly normal, and is a result of the GPU (graphics processing unit) in your Mac having to drive a much bigger and therefore more graphically intensive display. If you wish to curb this heat you could purchase a laptop cooling pad (see the laptop cooling pad section near the top of this page) and/or use the many other tips detailed here. Please be aware that it does not make a difference if your Mac laptop is open or closed - The computer will be able to vent it's heat just as well if it is closed than if it is open.

            Where are the vents on your Mac?

            It is important that you know where the vents are on your MacBook, as it's easy to unintentionally obstruct the vents of laptops, leading to overheating and all of the issues that come with it.

            On Classic MacBook Pros (these and these), MacBook Airs and the older white MacBooks the air vents are located in-between the screen and the body of the laptop. In the hinge, you could say. The Retina MacBook Pro line also has intake vent on the bottom-edges of the computer, here. The best way to stop your Mac laptop from the overheating is to avoid covering these vents. This is not a problem when you are using the computer on a desk, but if you're using it on your lap you may need to be a bit more careful.

            A common myth is that the MacBook family vent heat via the keyboard. This is false. No Mac laptop has ever vented heat through the keyboard. Therefore you are free to purchase and use a keyboard protector without worrying about it interfering with your MacBook's cooling system.

            All Noise and No Heat? - Why your fans might be running fast even though your Mac isn't hot...

            If your Mac's fans are unjustifiably loud, chances are the System Management Controller (SMC for short) is malfunctioning. The SMC controls many of the most basic, low level functions on your Mac, which includes operating the fans. It is not uncommon however for the SMC to mess up and set the fans to a high speed when not needed - An issue which can easily be resolved by resetting the SMC:

            Steps to rest the SMC on a Macintosh Laptop:

            1. Shut down the computer.

            2. Plug your Mac in, if not already plugged in.

            3. Press (left side) Shift-Control-Option & the power button at the same time.

            4. Release all the keys and the power button at the same time.

            5. Press the power button to turn on the computer.

            -----Internal Cleaning & Maintenance of your MacBook------

            Laptops tend to collect dust & lint in various places on the inside, and the MacBook family is no exception. Any computer will build up a fair amount of dust over a period of several years, however laptops also collect lint from your clothes, carpet, bed, couches and anywhere else they rest while your using them. Significant amounts of dust and lint in the heat sink of your MacBook prevents hot air from escaping, which causes the computer to run hotter, causes the fans to spin up more and makes the computer more vulnerable to overheating. In extreme cases there is a chance of the built up material catching fire, damaging components.

            It is recommended that you clean out your MacBook at least once a year. If your not sure how to go about it, this video will explain it to you:

            If your MacBook is relatively old, overheating may be caused by the fact that the thermal paste on the top of the processor and heatsink has gotten old and hard. But even if your MacBook is new this can be a problem, as it is not uncommon for thermal paste to be applied too thickly at the factory. So if you have tried all of the advice on this page and your MacBook is still abnormally hot, it might pay to reapply the thermal paste.

            Be warned that reapplying thermal paste is a fairly complex procedure, especially in MacBook Airs and Retina MacBook Pro's that aren't supposed to be opened up by the user. However if you are confident you can do it, or if you know someone else who can, remove your MacBook's heatsink before following these steps

            Have you noticed that your MacBook is running cooler after re-applying thermal paste?

            See results without voting

            Do SSD's run cooler than regular hard disks?

            After faster speeds and lower power consumption, another advantage of SSDs are that they supposedly run cooler than regular Hard Drives with spinning platters - It makes logical sense, as electric motors generate heat, and motion generates friction, which also generates heat. However while SSDs do technically run cooler than HDDs, the effect it would have on keeping your MacBook cool would be minimal. This is because your MacBook's hard drive is not one of the critical components (CPU, GPU & Battery) that gets excessively hot easily, and thus it does not matter if it gets a bit hot, and more importantly, it won't get hot enough to pose any problems. If you're buying a SSD anyway, due to the speed or battery life increases (for more info about getting a SSD for your Mac click here), or you're getting a new MacBook Pro or MacBook Air that has one, by all means enjoy the side benefit of the drive running a little cooler - However do not buy one just for the sake of cooling your Mac down, as there are many ways, much less expensive and far more effective, that you can take to cool it down.

            @anonymous: Yes - Your MacBook shuts down at a certain temp (around 100-105C depending on the model) in order to prevent the processor and other vital parts from being fried. However while this means your Mac can't get extremely hot and break down in one go, if the temp is constantly at 90-100C, bordering on overheating, it can damage it over a long period of time, which can shorten the lifespan of the computer.

            This is the most helpful article on this topic I've found on the internet, tm1. Thanks a bunch. There are some newer cooling pads to mention, I think, but at least finding that the general consensus is that a. reinstalling your OS, b. buying a cooling pad can help. Thanks!
