Been having an issue where my idle temps are >60C
The fan will spin for maybe a second or two and then turn off for 10-20 seconds
Checking /sys/class/hwmon/hwmon2/pwm1 and it is set to 0 even though my MINPWM is set to 90
Even if I manually tee 90 to pwm1 it will eventually reset to 0 even with fancontrol turned off
So something resetting without my input...
fan1_input does read fan speed & pwm1_enabled is set to 1
lsof & auditd do not have any info as to what is overwriting the file
Only way I can get the fan to stay on is to loop the tee command for a few seconds and then it is on that one speed
Turning fancontrol back on works for a while and changes speed as expected but eventually pwm1 goes back to 0
I found that when pwm1 is between 90-125 it does runs fine but once higher than 125 it resets
Then tried 125 as minimum and the working range becomes 125-160 before reset
Then tried 170 as minimum and the working range becomes 175-220 before reset
Could the fan be dying and the voltage/load send a signal to the kernel to say "shut down fan"?

tee command to force fan spin (only way to avoid resetting to zero), ctrl+c after a few seconds
while true; do echo 90 | sudo tee /sys/class/hwmon/hwmon2/pwm1; done
