Good afternoon, I have Ubuntu 20.04 operating system installed. My laptop(Lenovo b590) is equipped with Intel i3 3110M, RAM 12Gb, SSD 256, HDD 512, Intel HD 4000 and Nvidia GT720. I can't understand why the system is stressing the CPU, Psensor shows a temperature of 60C at times the temperature can reach 70C. Nouveau drivers installed enter image description here
As suggested by several comments, if top/htop doesn't show any abnormal activity, then:
- The computer must be cleaned, including fans,
- The thermal paste should be replaced (for CPU, GPU and visible heat sinks).
Most of the time just a small philips screwdriver is needed, thermal paste is not expensive. If you have kids around they will be pleased to help. You will be amazed to see the amount of dust of different origin you can find inside.
