    F17 Radeon (probably) overheating

    Hello,
    I recently installed Fedora 17 on my Asus G73jh laptop and few times it switched off because of high temperature.
    I assume the problem is with GPU not CPU, because in KDE temperature widget one entry is titled

    lmsensors/radeon-pci-0100/temp1

    After login it shows 70C and even if I do nothing it's raising slowly to 108-110C and computer switches off.
    The graphic card is ATI HD5870 and stock drivers. No problem under Win7.

    Re: F17 Radeon (probably) overheating

    With the radeon open source drivers the power management uses the 'default' power profile for the graphics card, which many manufacturers set to be the same as the high performance settings (so you get all the heat and the fan spins at high speed).

    An overview of the open source radeon power management

    Try out this command to see if it cools the laptop down:

    Code:
    $ su -c 'echo low > /sys/class/drm/card0/device/power_profile'
    If you want to set the profile at every boot then you will need to create or modify file /etc/rc.d/rc.local
    Here is the one that I use:

    Code:
    #!/bin/sh
    
    # Set radeon power profile
    
    echo profile > /sys/class/drm/card0/device/power_method
    echo low > /sys/class/drm/card0/device/power_profile
    Also make the file executeable:

    Code:
    # chmod +x /etc/rc.d/rc.local

    Thank you for annswer! It works like a charm now (only wonder why in previous Fedoras there was no such problem). And thanks for the link.
