GPU fan too loud with radeon drivers
I have an ATI Mobility Radeon HD 5870. Under Windows the GPU fan is inaudible, but under linux (radeon OSS drivers) the fan stays at 100% (very loud). I have already done this:


# echo profile > /sys/class/drm/card0/device/power_method
# echo low > /sys/class/drm/card0/device/power_profile

(source: ATI - ArchWiki)

Now it just fluctuates between medium and high speed. Is there anything else I can do to make the fan slow down (besides use proprietary drivers)?

The radeon drivers are still sub-par when it comes to power-management, even if you set it to use the low power profile. Since this seems to be a laptop I would recommend to use the proprietary drivers anyways.

The proprietary drivers are incompatible with gnome-shell and very buggy overall. I've spent the last 12 months trying to get the proprietary drivers into a usable state, but at this point I'm seriously considering selling this computer and buying a new one with an Intel HD 4000.

I had an ATI 4000 series card in my HP desktop, and was not successful in fixing this issue (debian testing). I tried to d/l and compile the proprietary driver from ATI without success (it compiled, but I was not able to load or use it). I tried 'fancontrol' and lm-sensors with the included fan detection scripts. All failed. A post somewhere suggested using an older radeon driver that was maintained in debian experimental distribution, but I was not brave enough to try this. I installed a new BIOS from HP (didn't help). My final solution was to get a new video card - a radeon HD6450 with NO FAN, for about $35. It has a heat sink over the GPU. It fixed my problem, no GPU fan noise, works perfectly with the stock radeon driver ... I'm now a happy camper.
