GPU fan speed control

AJUK · 19 Jun 2009 at 08:19

Justgot one of those shiny new Titan Nero systems and am very happy with it. Works great under Vista etc. but the Asus Radeon 4850 needs to run the Asus Smartdoctor software to control the fan speed and therefore noise levels.

I dual boot with Ubuntu 9.04 64bit and when I do the fans run full blast and is very noisy. I have the latest flgrx with the Catalyst controller running yet I cannot control fan speed. I know ATI stuff is pants with Linux but that is what I have got so I was hoping if someone had a solution.

I have looked over other forums but ideas seem lacking. Any help?

i don't have an ati card so can't try this.
from a google i found this

aticonfig --pplib-cmd "set fanspeed 0 100"

100 = 100%

The above is correct.

Thanks, I'll give it a go.

ccc has an option for fan speed in the overdrive...just activate the overdrive by clicking the box with the lock on it

Tried that before, it didn't seem to make any difference. I'll have another look though, thanks.

aticonfig didn't work and after reinstalling flgrx I discovered that there is no overdrive in the Linux version.

Thanks anyway.

7. ATI Overdrive (TM).
List adapters : aticonfig --list-adapters
Get Clocks of 0 : aticonfig --adapter=0 --od-getclocks
Set new Clocks for 0 : aticonfig --adapter=0 --od-setclocks=770,1126
Test out 3D : atiode -P60 -H localhost:0; echo $?
Check Temperature of 0 : aticonfig --adapter=0 --od-gettemperature
Commit changes for 0 : aticonfig --adapter=0 --od-commitclocks

It all works. There must be something wacky with getting the driver installed or it's some weird 9.04 issue.

I will keep hacking away until it works. I am going to remove all proprietary drivers and try again, I may even just wipe the partition and fresh Ubuntu install.

Thanks for the help.

if you going to give ubuntu another go try mint instead, its based off ubuntu.

Right, I have got it to work but only manually from within terminal using "set fanspeed" and I have adjusted by lowering the speed and temperature checking until I have a comfortable level. It is a lot better but I would be happier with some kind of automatic controller.

Getting there though, thanks again for the help.

Why do you need to do this anyway?

AJUK · 22 Jun 2009 at 08:06

Because the fan noise is horrendous!

Odd that they go full blast under Linux. The onboard bios should make them the same as under Windows.

Just put the aticonfig line into your /etc/rc.local file (before the exit 0 entry) and they will be set to that speed when you boot into Linux. Something like 30-40% will do.

AJUK · 22 Jun 2009 at 13:13

The fan speed is controlled by the BIOS, as it is in Windows. It is too loud in both systems but in Windows I installed Asus Smartdoctor that automatically adjusts the fan speed; without it it is just as loud.

You are right, around the 30% fan speed mark is quiet and the temp is mid 30 degrees C, so I will have a look at altering that file. Cheers.
