These programs display your CPU's temperature as a number. The maximum temperature will vary depending on the type of CPU, but typically, 50 to 80 degrees C is the maximum your computer should reach.

A good temperature for your desktop computer's CPU is around 120℉ when idle, and under 175℉ when under stress.

The Hot app is designed to let users monitor CPU temperature and throttling on Macs, and it's now compatible with the Apple M1 chip.
