Thanks for the reply - some really useful info there.
The motherboard is an MSI Neo-F (MS-7360) P35 Express. The BIOS is quite
up-to-date. There is a later version, but I'm a strong believer in "if it
ain't broke, don't fix it". I'll try putting the proper thermometer in to
I do think the case temperature is right though. The Seagate 500Gb hard
disk is reporting 29 degrees, so it must be reasonably cool in there.
It does seem to me that if it is that cool in there, then the heat inside
the processor is not transferring into the heatsink efficiently and
consequently not raising the temperature of the air in the case.
