Public bug reported:
CPU intensive work gets the temperature really high on all cores. Fan
does not increase speed as expected, sometimes leading to automatic
shutdown. The system seems to do some sort of load balancing when
temperatures get too high though.
example:
sensors:
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +78.0°C (high = +84.0°C, crit = +100.0°C)
coretemp-isa-0001
Adapter: ISA adapter
Core 1: +80.0°C (high = +84.0°C, crit = +100.0°C)
coretemp-isa-0002
Adapter: ISA adapter
Core 2: +79.0°C (high = +84.0°C, crit = +100.0°C)
coretemp-isa-0003
Adapter: ISA adapter
Core 3: +95.0°C (high = +84.0°C, crit = +100.0°C)
sudo pwmconfig:
(...)
usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
proc/acpi has no info on fans or thermal
