Why Do Computers Need Fan?

It’s earsplitting and irksome, right? If you’ve been wondering if computers really require fan fittings, you would find the reasons below helpful.
Computer CPU Generates Heat
The electronic chips of computer CPU produce more heat than can be dissipated at a time. The CPU is programmed to function below certain temperature threshold, so it needs a cooling system to keep cool. Once this threshold is exceeded, overheating is the result. This process known as “thermal check” is a common regulatory feature of all computers. So what happens when computer thermal check fails as a result of overheating? The computer’s functioning is disrupted, total lock or shutdown, and you would need to reboot the computer. Be mindful that overheating of computer CPU could lead to a fire.
All Sizes of Computer Produce Heat
It might be a wonder that even the smallest of computers generates heat that needs a cooling system such as fan. Yes, it is a fact! All sizes and shapes of computers have chips which are tightly circuited – little or no space between them. And these circuits have electricity moving through them at a very high speed – in milliseconds. Both the chips and circulation of electricity generate heat.
The Fan is All for Cooling!
The sole function of computer fans is to cool the system by drawing fresh and cool air from the outside into the computer chambers and components, especially, the CPU. In some computers, you find the fan as a component of its power supply where it is performing its cooling function.
The Fan Cools the Computer Through Vents
Computer fans don’t just do the cooling all by itself. Without vents in the computer, the fan would find it hard to circulate air through the computer components. There are tiny openings or vents in the keyboard of laptops and drive openings in desktops that help computer fans do their work. Always ensure the vents are not blocked.
If you neglect this, you would succeed in deterring computer fans from doing their job. And the next thing is overheating. You would end up shutting down the computer or even damage some of its parts. If you are using a laptop, make sure it’s not in its case while it is on. If you do that, you are simply overheating the computer and this could cause a fire.
Dusts Could Cause Overheating Too
There are other sources of heating in computers. Remember that computer fans draw cooler air from the outside. It’s not just the air that comes in; dust is also drawn in together with air. Keep it in mind that dust seconds heat when you talk about computer foes.
The computer chips, also static electricity, provide a suitable surface for dust to stick. When these dusts accumulate, they add to the heating of the computer chambers including the central processor or CPU. This makes overheating easy.
Make sure you regularly open your computers to clean out the accumulated dust to avoid damaging your computer components, the CPU in particular or the whole computer. You can do this using external electric fan to ensure all the dusts are out.
If you want your computer to last long, the formula is simple – take care of its fan!
