Why Do I Need a Laptop Cooler - Should I Have a Laptop Cooler for My Laptop
Need a Laptop Computer Cooler
I have quite often been asked : “Do I need a Laptop Cooler for my Laptop computer”?
I don't like to answer that with a direct Yes or No reply.
I would like the customer to make their own decision on whether they need a laptop cooler or not and to understand why they came to that conclusion. This is how I explain the situation!
As an electronics engineer I know what damage excessive 'heat' can do to a piece of electronic equipment and after all a laptop computer is precisely that.
I have seen charred circuit boards which had to be replaced at a great expense!
One thing a Laptop user should be aware of is that all electronic equipment generate and use energy simply by being used, and even when not in use!
This energy must be used up and is dispersed in the form of 'heat'.
Manufacturers of these devises are aware of this and build the Laptops to a standard that can handle this 'heat'. eg they will include in their design such things as:
- Fans that automatically switch on and off.
- Cooling slots.
- Feet to raise the laptop from a bench to allow free passage of air.
- Heat sinks to soak up the heat.
Laptop Cooler not required ?
Factors causing Excessive Heat in a Laptop Computer
So you will now appreciate that with a Laptop Computer, as with most electronic equipment, 'heat' as such is a fact of life and controlling this heat is a factor that manufacturers 'try' to build into the Laptops.
You can see by the diagram that if there were no feet on the computer there would also be no air flow to keep the laptop computer as cool as possible!
However there is no way that the manufacturer can control how their beautifully made Laptop is used by the consumer, this is where the decision arises on whether to buy a Laptop Cooler is raised!
There are many factors that cause a Laptop to develop enough excessive heat to cause damage to your lovely new purchase.
One reason can simply be 'ambient' temperature. Most consumer electronic machinery is built to operate at a temperature of up to 50 degrees Celsius maximum.
Now consider what would happen if you lived in a zone that had ambient temperatures over 40 degrees Celsius for days on end. You can see that your Laptop could quite easily reach a temperature over 50 c inside of its case. Remember that heat is an insidious enemy of your Laptop and the problem may only manifest itself over time!
That is one very good reason for buying a Laptop Cooler.

NO - NO never do this
Better idea in place of a laptop cooler
Another reason for Excessive Heat in a Laptop Computer
Another reason for buying a Laptop Cooler is the position where the Laptop is being used!
Lets say the user is sitting on a lovely comfortable lounge chair. They decide to use their laptop whilst watching TV.
OK the Laptop is sitting on their lap (for health reasons this is not good for a start ) so they decide to stuff a cushion under the laptop to raise the screen!
Can you see the danger here? The Laptop settles nicely into it's nice comfy cushion which immediately come up around the side of the laptop with the potential to block off all the air vents, preventing any cooling air to escape from the Laptop.
The cushion also may act like an insulation blanket keeping the laptop from dispersing all of the heat necessary to remain in its own safe temperature range!
You may not notice it straight away but do this too many times and over time your lovely new Laptop will not be operating so well.
My suggestion as an alternative to a cushion is something you already have in the kitchen and is what is called a Stable Table.
This will act as a cushion for you lap and keep the heat away from your important groin area and will allow for air to flow under your Laptop Computer and carry away the heat!
So the question remains, Do I need a Laptop Cooler
As most good engineers will tell you equipment is not designed to be run at it's maximum capacity for any length of time.
So in answer to your Question : Do I need a Laptop Cooler
My advise would be to err on the side of caution!
If the expensive of buying a cooler is not a problem then " yes" buy one for the occasions that warrant having one. If you can't afford one then follow the safety factors above!
Remember it would be a big enough worry when your laptop crashes but what about all of the data that you have stored on the Hard Drive of the Laptop Computer?
By the way did you 'back it' up like you have been advised?

Laptops and Notepads do generate heat, sometimes enough to do damage, it needs a laptop cooler to keep the heat away!
