I have the same problem and I'm looking for reasons... It's very strange.
If you guys wanna cold down the computer using (opensource driver )while official workaround doesn't comes out, just uninstall fglrx, remove /etc/X11/xorg.conf file and run this commands:
sudo su
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
this will turn off the GPU not utilised.
