this is my first post. and it is really a silly question, but here goes: Can you control fan speed on the radeon/r600g driver? Thanks
Not a silly question at all. You can't control fan speed directly but you can control power consumption via profiles and (on some systems) dyn(amic)pm, and reducing power consumption reduces heat buildup and allows the fan controller to reduce the fan speed. For more info on power control see the relevent section of :
Thank you for the help, I really appreciate it. I decided to run it on low power mode. It's sortof jerky in KWin and firefox scrolling, but it seems there is ~40F Difference in default and low power mode, so i guess i will keep it there.
Yes, it's huge difference. Also there is much more fan noise at default power profile. I am also waiting for proper dynpm implementation. Currently "dynpm" never goes to "low" and there is no fidderence between dynpm and default... It doesn't needed too hard to implement...

I dont know what model card you have or what cooler it has, but mine didnt sound any different between "low" "med" and "high" manual profiles. on low mine ran at ~104F, and on high ran at ~140F, but mine is a Factory OC Card, and has an improved cooler, so i dont have a clue on what it does with stock cooling/other chips. Mine is a radeon 5770, and im not gonna benchmark it to actually verify it, but im willing to say there isnt much difference between mid and high settings on this card (with the current state of radeon/r600g), even with a stock 5770
I totally agree with you though, they need to have dynpm go to low on desktop cards (i read it can cause problems with laptop chips, so i wont dis how it works there)
I am a n00b at forums, so this may be a little confusing. no anger intended.

... and it would also be nice if dynpm would work with multi-head.

When did you try dynpm for the last time? I had the same problems, but with 2.6.38 it works like a charm
