Just a few logs from my pc as per AMD reporting bugs instructions

I noticed that when i am playing a video game, the gpu fan seems to be quiet
for around 10-20 seconds, then gets too loud for around 3-4s, then back to
idle, and this repeats until i quit the game. Upon examination i found out =
that
for some reason the automated dpm sets the fan too low until temperature ri=
ses
too much (around 100C), then it sets the fan speed to 100% (around 3500RPM)=
, it
drops rapidly, and the cycle goes on and on like this.

I tried setting the fan speed manually through:

echo "1" > /sys/class/drm/card0/device/hwmon/hwmon2/pwm1_enable
and
echo "X" > /sys/class/drm/card0/device/hwmon/hwmon2/pwm1

and found out that for my card the only values that seem to work are: higher
than 199 (sets the fan speed to max) and lower than 196 (sets the fan speed=
 to
around 150-190RPM, the lowest my fan will go)

I think this is a bug, i don't have a Windows partition anymore but i don't
remember ever having this issue on Windows. My GPU is a Sapphire R9 380 ITX
Compact 2GB. I am using 4.18.16 kernel and 18.2.3 MESA on Archlinux.
