amdgpu sysfs section

I'm aware that there is already an entry about it in the ATI driver section. However, it seems we want all the fan information at one central place, so we might just want to link from there to here, and perhaps also on the amdgpu page. Also, most users these days use amdgpu and not ati/radeon anymore. If you argue that the solution via script is redundant to fancontrol: Relying entirely on sysfs and bash doesn't require any additional binary, which might help avoiding additional bugs and other troubles. It can also be more flexible to adjust to one's own needs. Of course it could also be placed in the amdgpu article, if you want mostly CPU related fan control around here.

Drastic updates to this page

Hi all. I've updated this page + moved "ThinkPad Fan Control" to this page too. What do you think? I've also created AUR script for "NBFC" tool, which I will update in the near future. There are many grammar mistakes and might be more logic mistakes, so I am calling everyone willing to help - contribute to this page. -- Erkexzcx (talk) 12:49, 10 September 2017 (UTC)

More details on manual settings

https://bbs.archlinux.org/viewtopic.php?pid=604431#p604431 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
