In this article I will give you some tips on keeping your desktop PC cool at all times.

Your Personal Computer contains a lot of parts, virtually all of which create heat when your computer is on. Some parts, like the CPU and graphics card, can get so hot you could in terms, cook them.

When your PC is properly set up, much of this heat is moved out of the computer’s case by a series of fans. If your computer isn’t eliminating the hot air fast enough, the temperature can get so hot that you risk serious damage to your PC; hence keeping your PC cool should be a top priority.

The easiest thing you can do to help keep your PC cool is to give it a little breathing room by removing any obstacles to air flow. Make sure there’s nothing sitting against any side of the computer, especially the back of it as most of the hot air flows out of the back end of the computer case. There should be at least 2 to 3 inches open on either side and the back should be completely open and unobstructed.

If your computer is hidden away inside a desk or cupboard, make sure the door isn’t closed all the time. Cool air enters from the front and sometimes from the sides of the case. If the door is closed all day, hot air tends to recycle inside the desk, getting hotter and hotter the longer the computer is running.

People believe that by running your computer with the case open will keep it cooler. It does seem feasible if the case is open, there would be more air flow which would help keep the computer cooler. The issue is however the build-up of dirt. When the case is left open, dust and debris clog the cooling fans faster than when the case is closed. This causes the fans to slow down and fail much quicker than usual. A clogged up fan does a terrible job at cooling your expensive computer components.

It’s true that running your computer with the case open might provide a small benefit at first, but the increase in fan exposure to debris has a much greater impact on temperature.

All of the fans inside your computer are there to keep it cool. If you wanted to know what slows a fan down and then eventually makes it stop is dirt – in the form of dust, pet hair, etc. It all finds a way into your computer and much of it gets stuck in the several fans.

One of the most effective ways to cool your PC is to clean the internal fans. There’s a fan on top the CPU, one inside the power supply, and usually one or more on the front and/or back of the case.

Just shut your computer off, open up the case, and use canned air to remove the dirt from each fan. If your PC is really dirty, take it outside to clean or all that dirt will just settle elsewhere in the room, eventually ending up back inside your PC!
