The CPU temperature is 90 degrees, is it normal?

Generally, according to Master Lu's display temperature, it is safe to control the temperature below 75 degrees, and the highest temperature should not exceed 85 degrees. When the temperature exceeds 80 degrees, it is easy to cause the computer to crash or shut down automatically, which is the computer's poor heat dissipation. How to say the fan speed mainly depends on the temperature of your CPU. Some computers have low CPU even if they run at 1000 rpm or more. Even if it's over 6000 rpm, your temperature is still so high. Generally, it is normal to be 35 degrees higher than room temperature.

The solution is as follows:

Clean the fan. You can go to the repair shop to clean it, or you can clean it yourself (if possible).

Re-apply thermal conductive silicone grease. Sometimes, after cleaning the CPU cooling fan, the temperature of the CPU does not increase obviously, so we need to coat the CPU with thermal conductive silicone grease again. Thermal conductive silicone grease will dry and crack due to long-term use, which will reduce thermal conductivity.

If it still doesn't work, you can consider changing to a larger diameter cooling fan.

The problem of high computer temperature is generally the problem of heat dissipation. For example, the cpu temperature of notebook computer is obviously higher than that of desktop computer. Mainly due to the small size of the notebook. Let's briefly introduce what factors are generally related to the high temperature of computer cpu.

Ambient temperature. Playing computer in summer is easy to get a high CPU, while playing computer in winter is generally lower. It will also be smoother to play, and the ambient temperature has a great influence on the CPU.

Cpu fan quality and host environment. The cooling fan also has a great influence on the CPU temperature. If your own computer fan is not very good, you can consider changing to a new fan.

Overclocking. Simply put, it is to control the core voltage of CPU. Many times, the CPU temperature does not reach the critical value at all, and the system restarts with a blue screen. At this time, the main culprit affecting the stability of the system is not temperature, but voltage. Therefore, in the extreme overclocking, how to set the voltage is very important. If the setting is high, the radiator will not stand, and if the setting is low, the CPU will not stand. Generally, overclocking technology is not recommended.

If you don't pay attention to the heat dissipation of the computer in summer, it will probably lead to serious consequences, which will not only affect the health and life of the computer, but also affect the user's mood.
