How reliable are KT6 or MSI board temps in general?

I just installed a kt6 and it's running my 1800+ dlt3c at 208*12 = 2492 mhz right now. I have prime95 running and my temps 55c cpu, 53c sys. I'm wondering becuase my temps were alot lower on my a7v8x. This is with my case open and a floor fan blowing in too. It seems a little on the high side.

Oh ya, this is with slk800a/ttsf2 @3500rpm/ceramique.

Might be about 5C to high, or it is getting it from the diode, but that really isnt that high of a temp considering the speed of the proc, and the Speed that you are running your fan. What voltage?

Hmmm mbm5 reads exactly 5°C less than the msi corecenter. I'll have to get a thermocouple and see whats what. I'm stable at 2.5 GHz on 1.8v now, gotta love it.
