I have posted the results below.
It took about 25mins before the givernor throttled the speed back. The full fan
speed did not even come and now I cannot change it back to 1.73.
The fan successfully controlled the temperature down so why throttle it
afterwards?
I am running a video, FF, Thunderbird, a disk usage analyser, and system
testing util to try and load it. The fan only comes on at above 60oC and even
then it's only half fan speed (fairly quiet), not the full fan speed that I had
in the past on Windows.
So, how come when it is set to ondemand, it throttles it to 800 when it gets to
this temperature and prevents me from changing it to performance?
