I didn't get to test the Radeon driver much (stuck with fglrx due to an issue) but one of the things that bothered me is the lack of a properly adjusted fan speed. I fully support a dynamic system of adjustment.
At least with 7.0.0, the fan speed is constantly slow with the "low" profile and constantly fast with the "high" profile. Regardless of what the card is doing, how much it's heated, or how hard it's working. My suggestion is to adjust fan speed (within a minimum and maximum range) either based on GPU / VRAM frequencies or based on card temperature when a temp sensor is available. This would be most useful with the dynpm method, so fan speed is only set to maximum when you play a game and matches the requirement. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1080350 Title: CPU Overheating with ATI driver Radeon HD Mobility graphics Status in X.org XServer - ATI gfx chipset driver: Confirmed Status in “xserver-xorg-video-ati” package in Ubuntu: Confirmed Bug description: Ever since upgrading from Maverick (with GNOME Classic) to Precise (using Unity 2D since using the default Unity makes the situation worse) my note book regularly overheats with normal usage: I've been regularly using: echo low | sudo tee /sys/class/drm/card0/device/power_profile I've am also using psensor to warn me if the temperature rises above 92°. When 'idle' the temperature is at about 80°. If the CPU is used (merely starting eclipse and letting all the the startup validation processes finish) it quickly rises to 88°. If the usages is sustained (rebuilding a java project) the temperature oscillates between 95° and 98°. If I do anything else that adds to the load (ie. if the temperature is >98° for short period of time), the system freezes, but the everything remains on, fans and CPU temperature stays up. I need to turn off the notebook by keeping the power button pressed. Note that this system overheats /with/ the low power profile.
