My system is quite unused at the moment:

%Cpu(s): 10.3 us,  3.1 sy,  0.0 ni, 85.9 id,  0.7 wa,  0.0 hi,  0.0 si,  0.0 s

but still the temps sensors give me are quite high:

Adapter: Virtual device
temp1:        +79.0°C  (crit = +88.0°C)

Adapter: ISA adapter
temp1:        +79.0°C  

Adapter: ISA adapter
Physical id 0:  +80.0°C  (high = +80.0°C, crit = +85.0°C)
Core 0:         +80.0°C  (high = +80.0°C, crit = +85.0°C)
Core 1:         +78.0°C  (high = +80.0°C, crit = +85.0°C)

Adapter: PCI adapter
temp1:        +88.0°C 

I cannot understand what process is causing the temperatures to be so high.

  • It isn't always down to CPU utilization. Is it a physical system? There could be ventilation issues. – Aditya K Apr 13 '15 at 15:38
  • Yes, it's a notebook. – ludiegu Apr 13 '15 at 15:54
  • Can you confirm the temperatures in the BIOS? Want to make sure it's not just a bug with Linux reading the temperatures wrong. – derobert Apr 13 '15 at 16:02
  • How old is the notebook and when was the last time you vacuum cleaned it? – Fabby Apr 13 '15 at 16:10
  • @derobert I'm quite sure the temperature is accurate, as the fan keeps working. It's strange as on Windows the fan is working on a more reasonable level. – ludiegu Apr 14 '15 at 8:03
