Can you run this script multiple times? First time I ran it it gave me an error about the on board video not having a fan, but it set the other cards fans to what percent I told it.

But on subsequent runs it doesn't return errors, no changes to the fan speed, nothing.

Hi,
I'm on ubuntu 16.04 lst and i've a r9 fury but the fans doesen't spin
i've used "sudo ./amdgpu-pro-fans.sh s 80" but nothings happened, in windows the videocard works fine
ideas?

Hi there, I have installed your app and when i run

sudo ./amdgpu-pro-fans.sh -s 40

The fan speed drops to 40% for around 10 seconds then speeds up again.

How do i set to remain at 40%

Ubuntu 16.04 4 x RX490

Thanks for share it.

This code could also help to identify the GPUs. If it run up and down the speed of the fan per gpu, one at the the time, it could help to knpw which is each gpu .

Anyway thanka

I run amd pro fans and change the speed of my fans to 75% but now i want to restore my gpu's default setting that controls automatic in consideration of temp my fans. How can i do that?

Thanks!

I dont know what to do

so i have been using this on my other rx580 with no problems. tried setting fan speeds on a system with 2 r9 295x2 and i keep getting the following errors.

head: cannot open '/sys/class/drm/card0/device/hwmon/hwmon0/pwm1_max' for reading: No such file or directory

the r9 295x2 are oem water cooled cards with a fan on radiator and a vrm fan. i someone could help i would be very grateful

Add feature to allow setting of setting each GPU's fan speed independently.
(Some GPUs run hotter than others :) )

Why am i getting this on Ubuntu 18.04
echo: write error: Invalid argument

Usage Example:

sudo ./amdgpu-pro-fans.sh s 80 That would set all of your fan speeds to 80 percent of their maximum speed. The argument works perfectly as of the current stable release.

sudo ./amdgpu-pro-fans.sh -----> "-" s 80

i have 13 card and code set fan speed for only 10 cards ;( how it can set for all 13 cards !
