Hello all
I'm basically trying to find out how to get a XFX Radeon 5870 to be cool while performing well under Linux. This requires me to modify the cooling on the card as bit, as the stock cooler sound level varies from not-that-noisy to jet engine level. The thing is, the GPU doesn't seem to be the hardest thing to cool on this card, the VRM (voltage regulator modules) are. The card consumes about 180W when running at full throttle, and a significant amount of this heat is deposited in these tiny VRMs.
In Windows there's a tool called GPU-Z which allows you to see the temperatures of these units:
I'm looking for a way to read these temperatures using the Catalyst driver under Linux. I assume it's possible somehow, since I'm using the Catalyst driver, which is also what's used under Windows with GPU-Z. A hackish way is totally fine for me, I don't need a fancy GUI program like GPU-Z.
Is it possible using "aticonfig --pplib-cmd" somehow? I know I can get fanspeed readings using this command:
and set them using this command
and the following commands reads the VDDC levels (in volts), so we're getting close:
Is there a similar trick to get VRM/VDDC temperatures?

Code:
aticonfig --pplib-cmd "get fanspeed 0"
Code:
aticonfig --pplib-cmd "set fanspeed 0 <fanspeed in percent/auto>"
Code:
aticonfig --pplib-cmd "get activity"
