# pwmconfig version 3.6.0 | |
This program will search 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. | |
We will attempt to briefly stop each fan using the pwm controls. | |
The program will attempt to restore each fan to full speed | |
after testing. However, it is ** very important ** that you | |
physically verify that the fans have been to full speed | |
after the program has completed. | |
Found the following devices: | |
hwmon0 is nvme | |
hwmon1 is nvme | |
hwmon2 is zenpower | |
hwmon3 is iwlwifi_1 | |
hwmon4 is it8792 | |
Found the following PWM controls: | |
hwmon4/pwm1 current value: 255 | |
hwmon4/pwm2 current value: 255 | |
hwmon4/pwm3 current value: 255 | |
Giving the fans some time to reach full speed... | |
Found the following fan sensors: | |
hwmon4/fan1_input current speed: 826 RPM | |
hwmon4/fan2_input current speed: 1250 RPM | |
hwmon4/fan3_input current speed: 820 RPM | |
Warning!!! This program will stop your fans, one at a time, | |
for approximately 5 seconds each!!! | |
This may cause your processor temperature to rise!!! | |
If you do not want to do this hit control-C now!!! | |
Hit return to continue: | |
Testing pwm control hwmon4/pwm1 ... | |
hwmon4/fan1_input ... speed was 826 now 825 | |
no correlation | |
hwmon4/fan2_input ... speed was 1250 now 1256 | |
no correlation | |
hwmon4/fan3_input ... speed was 820 now 823 | |
no correlation | |
No correlations were detected. | |
There is either no fan connected to the output of hwmon4/pwm1, | |
or the connected fan has no rpm-signal connected to one of | |
the tested fan sensors. (Note: not all motherboards have | |
the pwm outputs connected to the fan connectors, | |
check out the hardware database on http://www.almico.com/forumindex.php) | |
Did you see/hear a fan stopping during the above test (n)? |
