mantas: can you install the latest kernel in Dapper (-23), eg: do a:
sudo apt-get install ubuntu-desktop
can you run 'top' from a terminal and see what program is at the top. If it's "modprobe fan" then this could be: bug #46303 which is currently showing up on an Acer.
Can you also try Alt-SysRq-t from a terminal (press Ctrl-Alt-F1) to get a kernel traceback.
