This laptop was tested with Debian 7 “wheezy” and Ubuntu 12.04 LTS. Prior to installing, the BIOS was updated to version 1.15. The fan in the laptop somehow seems to be connected to the graphics chip. Without proper dynamic power management for the radeon graphics, the fan will spin at full speed after some time.
For both aforementioned distributions, a few changes were needed in order to make the fan quiet:
- an upgrade to at least kernel 3.11.x
- the kernel needs to boot with the parameter “radeon.dpm=1” in GRUB
- an upgrade of the linux-firmware packages (I used version 0.40 from unstable, but the ones from wheezy-backport should work too)
This will enable the new dynamic power management for the open-source radeon driver. Without these steps, changing the brightness of the screen with the Fn keys will cause a kernel panic and the fan will either be off or on at full speed.

These changes should no longer be necessary with newer distributions shipping with kernel 3.13 or higher. If you can get the closed-source fglrx drivers to work, then the fan should go quiet too, but I didn't bother with those.
