Our computer contains a lot of parts, almost all of which create heat when the computer is on. Some parts, like the CPU and graphics card, can get so hot you could cook on them. If your computer isn't removing the hot air fast enough, the temperature can get so hot that you risk serious damage to your PC. Needless to say, keeping your computer cool should be a top priority.
Clean Your Computer Cooling Fan
One of the most effective ways to cool your PC is to clean the internal fans. There's a cooling fan on top the CPU, one inside the power supply, and usually one or more on the front and/or back of the case.
Allow for Air Flow
Make sure there's nothing sitting right against any side of the computer, especially the back.
Stop Overclocking
Sometimes I recommend you reconfiguring your hardware to factory default settings, the premise is you are very familiar with this condition.
Replace the Power Supply
Your computer can heat up quickly if the cooling fan on power supply isn't working. Unfortunately if this fan is no longer working, you'll need to replace the entire power supply.
