Description felix.oxley 2015-10-19 23:01:02 UTC 
Hi, Ubuntu 15.10 Linux 4.2
MSI Radeon R7 360 

Goal : Reduce fan noise at safe temperature e.g. ~25 degrees

Problem: PWM1 value below 50 does not affect fan speed
e.g. /sys/class/hwmon/hwmon0# echo 0 > pwm1

I have tried manually controlling PWM and also the pwmconfig script and fancontrol.

Are you able to turn the fan off completely in windows?  It's possible the fan the OEM used only goes down to a certain level.  Please attach your xorg log and dmesg output.

Hi,

I don't have an easy way of running Windows on this machine.

The dmesg is currently empty.
Xorg log attached.

Thanks

Please attach a copy of your vbios:

(as root)
(use lspci to get the bus id)
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/vbios.rom
echo 0 > rom
