Comment # 83 on bug 73338 from 
Hi,

maybe this question is a bit silly, but how do I enable fan control? I just
compiled and installed 4.0.0-rc1, but my fan is still spinning rather loudly.

I'm using a Sapphire 7850 OC. Is the following the correct path for fan
manipulations?
/sys/class/drm/card0/device/hwmon/hwmon2

Below, I find the following pwm1/temp1 nodes:
pwm1, pwm1_enable, pwm1_max, pwm1_min and temp1_input.

cat pwm1_enable crashes my system.
cat pwm1 -> 86
cat pwm1_max -> 255
cat pwm1_min -> 0
cat temp1_input -> 27000

Same result with 3.19 with patches applied mentioned in Comment #80

Do I have to set special kernel features or did I set special features I should
not?

Many thanks for your help.

Raimund
