* If you own a high-end computer and the cooling system is not enough to keep the CPU cool and if the system restarts or is affected by overheating, invest in a water cooling system or a heavy-duty CPU fan.

* The CPU should not be placed in a cabinet or in places where there is no air circulation. It should be placed in a cool place with enough space for the hot air to blow out.

* Fans and the inside of the CPU should be regularly dusted as dust and other particles easily block the fans in a CPU, a portable vacuum cleaner or a brush can be used to clean the inside of the CPU.

* Rearrange the cables inside the CPU, this helps in free movement of air inside the CPU. The cables should be arranged in such a way that they are not in front of the cooling system. In case of more than one hard drive, place them slightly apart.

* If your financial situation doesn’t allow you to invest in a new cooling system, you could open the side panel of the CPU and place an electric fan nearby, it is one of the most commonly used temporary fixes. Always remember to close the side panel after use.
