How to Cool PCs for Beginners


When working with modern computers there are many parts involved that can produce large amounts of heat, leaving to all sorts of problems from random crashes to the computer shutting itself down. There are many ways of dispersing the heat that can range from simple fixes that anyone can manage in a matter of minutes to more complex processes that need to be done with more knowledge of the internal workings of computers.



    1. 1. Ensure that all vents and fans are clear of obstruction



If the vents and fan ports in your computer are covered or otherwise obstructed and can’t get enough airflow you won’t be able to get the heat dispersed quickly enough as computers use the fan ports to vent the heat out of the case, if enough cool air can’t be brought into the case due to obstructions of the vents and fans you will never be able to cool your PC.



    1. 2. Add additional fans to the cooling systemH2_1



Upgrading the cooling system by adding more fans in positions that bring more air into the case while venting the excess heat using other fans placed opposite the intake fans on the other side of the case.



    1. 3. Properly clean and maintain the inside of your case



Computer cases are dust magnets, and tons of dust can build up around key parts, making it more likely for them to overheat, a heat sink completely coated in dust is able to disperse heat less efficiently than a clean heat sink. Be careful when cleaning out your case, and don’t use any water or other sprays inside the case of your computer as this can damage parts instead of helping the situation. Using a low power vacuum cleaner or a can of compressed air to get the dust out of your computer is a good option instead.



    1. 4. Reapply thermal paste to your CPU in order to allow the heat sink to disperse heat properly



As you dust out your case you’re likely to remove the heat sink from above your CPU in order to get all of the dust out of it. At this point you should also invest in a cheap tube of thermal paste from an online site such as and apply this to the bottom of your heat sink before replacing it, this paste will help you to control the way heat is dispersed through the heat sink.



    1. 5. Use computer BIOS settings to customize the way the fans work



Most modern motherboards support using the BIOS to set your fan speeds and the temperatures that the fans will kick in or speed up to vent hot air from your case, allowing you to fully customize just how much your fans work to keep the internal components of your computer cooled off and working properly.


If you follow these tips and maintain your computer regularly you should be able to keep your computer running cooler than ever before while you work or play games, ensuring that you have the best experience possible every time you use your computer day to day and prolonging the life of your setup and lessening the risk of hard drive failure and other crashes or errors.
