Today my Librem Mini v1’s fan is running full duty cycle.
While the CPU is idle.
Im using PureOS byzantium.
I will check if there is some wiring issue ( I have seen this lately on the forum ).
I will post back with my findings.
Nothing unusual about the cpu fan connector.
All looks ok for now after re-assembly and boot up…
I don’t like this
I suggest thermal monitoring of the device. At a minimum look for any log entries that may be relevant.
How did you establish that the CPU is idle?
I don’t know if its the case here, but there is an old bug in LInux that a sensor reports the wrong temperature after suspending and it causes the fan to go full speed. A reboot DOES NOT fix it. You either need to do a full poweroff and restart or suspend and wake it again (usually works). Try these two things and lets us know.
Yea I had to power cycle to fix it.
I am using htop and top.
There was nothing obvious about thermal or error|critical in dmesg -T and in /var/log/syslog
