pwmconfig - Unix, Linux Command
pwmconfig - tests the PWM outputs of sensors and configures fancontrol
searches your sensors for pulse width modulation (PWM)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have PWM
circuitry installed, even if your sensor chip supports PWM.
It attempts to briefly stop each fan using the PWM controls. It then
attempts to restore each fan to full speed after testing. However, it
is very important that you physically verify that the fans have
been returned to full speed after the program has completed.
This program will stop your fans, one at a time, for approximately 5 seconds each.
This may cause your processor temperature to rise. Verify that all fans are running
at normal speed after this program has exited.
