On my HP laptop I'm also using: echo low | sudo tee /sys/class/drm/card0/device/power_profile
Luckily, it doesn't have any negative side effects for me ( I know some other have). My fan's speeds, that gkrellm reports are: 0, 50, 70, 80 100 % If I don't set the power_profile to low, my fan usually spins at 80%, few seconds after I set it to low, the far spins down to 70%. Not a bad start, but I was able to make it better: WARNING: this will require you to remove the heat sink and fan and probably will VOID your warranty!!! I bought some "Arctic Silver 5 Thermal Compound" with the cleaning kit (~$10) and replaced the existing thermal compound. Do NOT over use it! The heat issue kept getting better and now - after couple of month - from cold boot my laptop's fan completely turns off after the initial spin on the BIOS screen and it stays off for 8-9 minutes. Also, during every day use the fan spins at 50% vs. 70% as it used to. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/748080 Title: ATI card fan is always on with opensource radeon driver To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/748080/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
