Hi,

I was testing the 0.8b version with my 570 -- you have to be sure that
the fan works and is ON.  I had seen 80°C when the machine was under
load (e.g compiling the kernel).  It happended to me, that after
software suspend, I could not turn the fun on.

In other words -- be carefull and watch the temperature.
Test the system if the fun is turning on when needed...  I have no idea
if there are any hardware protection...

Regards,

Paul Ortyl
