Is it normal for cpu fan to rotate at 248 1 57 ~ 59 degrees?

The CPU is generally designed to work at 90 degrees, and the fan is also normal at 248 1 rpm, and many people have more than 3000 rpm. Fan speed design is generally below 4000 rpm.

It is normal that the temperature is lower than 30-55 degrees and 85 degrees when fully loaded, and some machines are slightly higher. As long as it doesn't exceed 90 degrees, there's nothing to be afraid of.

Without temperature detection, are we not using it well? With temperature detection software, worrying is just a psychological effect. The hardware is temperature protected. When the temperature is high, it is usually a blue screen, a crash or an automatic shutdown. Take measures when you find this situation! Now the weather is getting colder and colder, and the temperature will drop by itself. Feel free to use it!
