Can you get thermal readings through lmsensors or other tools?<BR>
<BR>
Sounds like thermal controls are set such that the driver does not provide proper cooling;<BR>
or throttling of the fan. I have used a Windows tool (at work) from an F/LOSS project <BR>
called Open Hardware Monitor (includes a Linux port) that has given good results. I<BR>
might suggest getting some data on system temps and see if you can further nail down<BR>
where the issue lays. <BR>
<BR>
See: <A HREF="http://openhardwaremonitor.org/">http://openhardwaremonitor.org/</A> for more information...<BR>
<BR>
It may well be that the driver support for fan control isn't properly implemented on your <BR>
hardware or it is missing altogether. Dunno...worth delving into a little more I would think...<BR>
<BR>
Cheers! <BR>

Many thanks for the suggestions. I will be sure to clean the fan vent.
But the issue really does come primarily from the Catalyst driver.
Evidence to wit: 1. No overheating in Windows at all. 2. No
overheating in Linux when the Catalyst proprietary driver is
installed. There is an open source driver included in X-Windows, but
it doesn't fix the overheating issue on my model. So, whenever I go to
install Linux, the clock is ticking until I install the driver. This
is a known issue with ATI cards. Until recently, the driver wouldn't
play at all with Gnome 3, but that has been resolved. I will avoid ATI
cards from now on out.
