Solution 2: Keep Your Computer Cool

The computer generates a lot of heat when it runs. If your computer accessories don't remove the hot air from the computer as soon as possible, it will cause the CPU temperature to be too high, so you need to take steps to cool your computer. Below I will provide several ways to reduce the temperature of your computer.

  1. Upgrade the CPU fan. If the CPU fan performance is not high, the heat generated by the computer cannot be eliminated in time.
  2. Install another fan. A fan may not solve your CPU overheating problem, so installing more than one fan will work.
  3. Install the Water Cooling Kit. If your computer is configured too much and the fan can't solve the problem of too high CPU temperature, you can install the water cooling kit. This is a very safe accessory, and you don't need to worry about damaging your computer.
