As I was checking the kernel logs I noticed :
kernel: CPU2: Package temperature above threshold, cpu clock throttled (total events = 13430).
I have 4 CPUs and all of them have the same issue. My laptop hardware info :
CPU info :
Model name: Intel(R) Core(TM) i7-3537U CPU @ 2.00GHz
I can hear my laptop's fan working, but sometimes it really gets hot and I can feel it through the case.
In Windows-10, although CPU usage gets high, the temperature is usually normal.
Any idea what may have gone wrong? and what can I do to further investigate this issue?
I checked thermald.service status and I found this line :
thermald:sysfs read failed /sys/class/thermal/cooling_device0/cur_state
