ATI 5770 fan speed

alconn · #1 6th May 2010, 11:14 PM

Hi,

I've just downloaded and installed the Fedora 13 beta and was wondering if there was any way to slow the fan down on my ATI 5770. I know the proprietary drivers do this but catalyst 10.4 won't install on Fedora 13 for some reason (I guess xorg version not supported).

Does anybody know if there is a program or some way I can get the fan to spin at a normal speed using the open source ati driver (or a way to force cat 10.4 to install)? It's spinning at 100% at the moment and sounds like a 747 taking off!

If there isn't a way then unfortunately it would be a show stopper and I'd have to go for another distro. It'd be a shame cos I'm really liking the look of this Fedora release, this is the only problem I've found.

Cheers

if you install the 2.6.34 kernel you can enable power management for the open source drivers which should clock down your card on idle, but I have no idea if it will slow down your fan.

You can find the 2.6.34 kernel rpm's here: http://koji.fedoraproject.org/koji/b...buildID=167919

After that edit your grub menu.lst and add this to your grub commandline:

Quote:

radeon.dynpm=1

It should look somethin like this: http://img64.imageshack.us/img64/9834/screenshotpz.png

To see if dynamic power management was successfully enabled use this command:

Quote:

dmesg | grep drm

You should see this in the output:

Quote:

radeon: dynamic power management enabled
[drm] radeon: power management initialized

ATM cat does not support the version of xorg fedora uses (or the kernel I think too) if you end up having to go for another distro ubuntu would be a good bet for you as it has a newer pre-release version of catalyst in its repositories.

Hi,

Thank you very much for the reply.

Unfortunately it didn't work. On bootup all that happened is that my monitor went to sleep. That's probably the powersaving feature!

I'll keep fedora installed for now and use ubuntu on the other partition. I hope ati come out with some drivers that work with it soon.

Thanks again for the help.
