More details on manual settings I found this post very enlightening. Read it if you're interested in the details (esp. on manual setting of fans). Maybe something like this should be in the main article? --Unhammer 02:45, 1 October 2009 (EDT)

Increasing fan_div?

I found this section not very helpful. What is the fan divisor, why would I need to increase it? "Edit /etc/sensors3.conf and look up the exact chipset." How do I find the chipset that I'm supposed to be looking up?

By the way, how many motherboards simply don't have the capability for software fan control? E.g. how do I know when I should give up on these instructions? For instance my MSI Wind has a directory /sys/devices/platform/msi-laptop-pf/, since I don't see anything related to fan control there, perhaps that means I'm out of luck? Whereas my Thinkpad has /sys/devices/platform/thinkpad_hwmon/fan1_input, etc... I wonder if these kind of hints should be incorporated into the instructions.

Also editing sensors3.conf is wrong and there are many chips not in there. Ziusudra (talk) 06:06, 26 February 2016 (UTC)
The real problem is that the only thing that should be in the #Sensor driver section is a link to the Lm_sensors page saying to get the fan and temp readings working and the explanation of the module loading order. Ziusudra (talk) 05:14, 27 February 2016 (UTC)
Not quite sure if it's related, but I am unable to set anything using fan_div instructions. I always give following message using sensors -s:
Error: File /etc/sensors.d/fan-speed-control.conf, line 2: Unknown feature name coretemp-isa-0000: No such subfeature known

Yet it should be the way to control it, since I was able to do it on windows using very specific laptops fan control app [1]. Also, the following command sets fan speed:

echo "100" > /sys/class/hwmon/hwmon1/pwm1
