Dear Maintainer,
The DELAY=5 seems to be too low for a Lenovo Thinkpad T14s Gen3 AMD. I'm
getting the "no correlation" message when pwmconfig tries to detect the
PWM->fan correlation.
Once I see the message "Testing pwm control hwmon6/pwm1 ..." I do
immediately hear the fan to go from its disengaged maximum of 4900 RPM
to 0 nearly instantly, however it seems it takes a while to get propagated
to /sys/class/hwmon/hwmon6/fan1_input.
In my tests DELAY=10 seems to be at the border, it usually works but
sometimes fails. DELAY=12 or greater seems to be reliable.
You can find a few example outputs (with some extra debug output lines
I had added) for various DELAY values below.
The UEFI System Firmware should be the latest available today (0.1.25
according to fwupdmgr).
Regards, Linus

$ sudo pwmconfig
# 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 PWM controls:
hwmon6/pwm1 current value: 0
Giving the fans some time to reach full speed...
Found the following fan sensors:

Warning!!! This program will stop your fans, one at a time,
for approximately 5 seconds each!!!
This may cause your processor temperature to rise!!!

There is either no fan connected to the output of hwmon6/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,
