I am having the same problem with 10.0 Official. My system is well below Intels recomended temp. I didnt have this problem with 10.0 community. Any ideas on how to get around this?

I don't know whether this helps but under Mandrake 10.0 Community running the 2.6 kernel i get CPU & MB temperatures 10 times as high as under the old 2.4 kernel. This didn't cause me any problems however I am wondering whether this has anything to do with the problem (i.e. apparent temp of 450C). At a guess try booting to the install CD/DVD in rescue mode and check what the sensor readings are (on my system "cat /proc/sys/dev/sensors/it87-isa-0290/temp3" does the trick). Anyway try and disable the check in the boot scripts.

Hope this helps.
