How to Avoid Computer Overheating

Updated on November 3, 2012

Computer overheat causes

Computers overheat because of two main reasons:

Over-performing: Normally what overheats in your computer when it is over-performing is the CPU - a little "square-like" component that processes data. CPU stands for Central Processing Unit. When the computer is over-performing, or doing something beyond its stable capabilities, this puts an extra strain on this processing unit making it calculating lots more per second and it eventually overheats. The solution for this problem can be found on the "Over-performing Solutions" section.

Poor Ventilation System: The most common problem with the ventilation system are the clumps of dust that gather inside the computer. These clumps can help the heat to accumulate inside the box or even damage and stop the fan blades, making them useless. The solution for this problem is in the "Improve your computer ventilation system" section.

How to know if overheating is the problem?

Well, you may be noticing your computer is slow or too hot but you may not know what is the problem. A good sign that it is an overheating problem is the fan speed. You can hear the fan working since you switch your computer on. The fan should always alternate between speeds and you will hear the fan speed sound go higher and lower.

In a computer which is overheating, the fan will always work at its maximum power. If you are noticing this - your computer is overheating.

Another clear symptom is - the computer just switches off on suddenly.

Its like the human body - it faints when you are too hot or making too much of an effort. It plugs off because it is forcing you to let it cool down to avoid motherboard or component damage. If this happens you should always let it cooldown.

Over-performing Solutions

1 - Get rid of spyware and malware

One of the main reasons computers start to over-perform is because they are running lots of things at the same time. Spyware and Malware usually run in the background.

To diminish the number of processes your CPU has to run trough you should get rid of all the spyware and malware (this will help you preserve your security too). To do this, you should download the trial version of Kaspersky Internet Security or another software dedicated to make this happen.

2 - Free some disk space

If you don't perform clean ups on your computer often enough, chances are that its full of virtual litter that can clump up your computer so effectively like physical one. You should right-click your disk and in properties click disk cleanup. Get rid of cookies, internet files and empty your recycle bin. Go overboard and delete files you don't need, get rid of thrash!

3 - Defragment your Hard-drive.

When you do things on the computer, it scatters data on the disk to be able to respond quickly, however the second time around the computer needs the info it has to go back to those pieces and this takes time. To speed up the computer you should defragment the hard-drive. This will pull the pieces together speeding up response time.

4 - If you are Gaming

Download a Game Booster software. This allows you to activate "gaming mode" which disables useless processes for the game to run, making it respond quicker.

Improve your computer ventilation system

In case of a desktop computer:

In case of a desktop computer, you probably won't need much to get your cooling system up and running perfectly. Desktop computers have a nice intake and outtake of air and in 95% of the overheating cases - its clumps of dust causing it.

Here is what you have to do:

1 - Take the side of the box with a screwdriver

2 - Use rubber gloves to avoid damaging the computer components with static electricity

3 - Clean your hardware - mainly the fans: Make sure the fans are working properly.

Additional measures you can take are setting up your computer box next to an air conditioning vent or on the floor - where the air is cooler. Avoid fireplaces and heaters next to it.


In case of a laptop:

This is trickier. You see, processors nowadays are very powerful and the laptop boxes have a poor air flow. To avoid overheating you should buy a cooling platform with fans to place your laptop on.

Avoid having the laptop on your lap or on your bed sheets - this is a death penalty for it.

You should do a little research in water cooling systems for laptops, because they are the most efficient.

Check out some heating damage - don't try this at home!

      Hello mate,

      Have you tried to repair your OS? Maybe your computer overheated once and damaged a system datafile and a quick run with the OS's Cd could fix it!

      Regards,

      what i do....? my ( hp g62) laptop ...sowing over When I start my laptop I get this annoying message every time:

      "The system bios has detected your notebook PC was placed in hibernation to avoid overheating .

      The system is now operating normally and your data should remain intact.

      Overheating may occur if the cooling vents are blocked or the operating temperature exceed the specification. The notebook PC should return to normal operation once the situation is resolved.

      System Temperature (90D)"

      So i have to press Enter every time to start my OS.... it's annoying and can't get rid of it, I don't have temperature problems or anything, my laptop is over a cooling pad and it's not hot, there are no problems while using it, its just that message and the fact that i have to press Enter every time to boot ...

      Is there a way to get rid of it?

      I tried flashing the bios with the hp tool but with no success ...

      I have never heard of water cooling system for laptops. It would be great if you could emphasize more on that. The most common overheating prevention are to keep the machine dust free and under cool temperatures.

      This is actually very useful! Bookmarked and shared. Voted up and useful. Many people have problems with maintaining the "heat" factor of their PC's and laptops, I think this is a savior to answer these problems.

      True, True! Don't put desktop pcs upside down!

      Very useful article! This is information that can help a lot of users save their computer from irreparable damage.

      One thought though, on the quiz, on question three the questions asks if your computer shuts down due to overheating what should you do, and the answer is leave it upside down.... but this is only correct for laptops. A desktop would just look odd upside down. :-P

      Thanks! Yes most of the laptops overheat because processors are getting more powerful and the tiny size of the laptop's cooling systems is not growing too.

      What a great hub. My laptop overheated and shutdown just two days ago. I knew enough to perform a few of these steps on my own but I've learned so much more after reading your hub.

      Maybe I'll do a hub about cooling systems! Laptops are prone to overheating even if you dust them off... but I use stands with 2 fans and it solves it

      Quite good compilation for computer overheating problems and methods of avoiding them. I have never heard about water cooling systems for laptops. Could you tell a little bit more about that.

      The best solution to avoid laptop overheating is regular dust cleaning. It is hard to this by yourself, but I suppose, professional computer engineers can help cleaning dust. Laptop disassemble process is not so hard, if you know, what you are doing.
