How to Prevent Your CPU From Overheating?

CPU overheating or PC overheading is a common issues, especially if you game for prolonged sessions. Here is how you can prevent it from happening.

Your PC generates a lot of heat as the different components like the CPU and GPU keep running for a while. Generally, your system is built with fans to dispense some of this heat outwards to keep it from heating up too much. However, if your system is not removing the hot air fast enough due to some blockage or other reason, it leads to a dangerous temperature increase that could be very harmful to the PC. Keeping your PC from overheating is very important so just try any of the following methods if you face the problem of overheating.

1. Remove Obstacles That Prevent Cooling
The most obvious solution is to ensure that the fans have room to dispense to heat out of the computer’s case without obstruction.

Generally, hot air flows out of the back end of the computer case so leave 2-3 inches open behind it with no obstructing materials. Avoid keeping your laptops in closed up locations where cool air cannot enter.

2. Keep the Computer Case Closed
An open case can lead to dirt and other debris becoming jammed up in the fans faster which leads to the fans getting slower. Keeping the computer case closed will reduce the chances of this happening.

If your computer is in a location that has a lot of dirt or is too hot, then just move it elsewhere.

3. Upgrade the CPU Fan
Your CPU can become overheated much more easily than other components because it is the most sensitive part of your PC.


Upgrading your current fan will ensure it does more than just cool processors long enough to keep things working for a while.

4. Install Case Fans
Attach a case fan or two to the front or back of the computer case, from the inside. These help move cool air in the computer while flowing hot air out. In the case of laptops, you cannot install these but can make use of a cooling pad.

5. Time your Usage
Keeping your computer system running for a long period of time in which it has given no breaks in between performing heavy processes can lead to overheating.

This is known as ‘Overclocking’ and can become an issue if you do not time your PC usage.

6. Replace the Power Supply
Not having a case fan means your PSU fan has to do the job of removing hot air itself. If the fan stops working, you will need to replace the entire Power Supply.

7. Get a Water Cooling Kit
For high-end PCs that do more processing, installing a water cooling kit may be a wise option for lowering the temperature. A pump cycles cool liquid down to the CPU while pumping out the hot liquid. These are fairly easy to install!

8. Install a Phase Change Unit
This works like a refrigerator that cools your CPU and costs between $1-2k.

This is how you can prevent your CPU from overheating. If you have any other suggestions, feel free to let us know!
