Steven,
I think AFI is right... It's clearly impossible to see positive temps on an evap provided cooler is working properly... Positive in MBM, yeah... In BIOS - maaybe...
Before that 146, I had a chance to play with Eric's Opteron 150. It was
THE hottest thing I ever, ever played with!
SmallFFT would load it to 15C in MBM @ 3.2Ghz 1.62v!!! :shocked:. BIOS temps at the same time were -12C!!! I re-mounted the head like 3 times because I could not believe my eyes :D Yet, evap stayed at -39C LOAD (during that SmallFFT "challenge"). This is when you know, that IHS is a major limiting factor. But not all Opterons are like that and I think that it's just a far generalization that Opterons are somehow hotter... Remove the IHS off of any of those "hot chips" and you'll see temps drop drastically.
My 146 ("very warm" with IHS) without IHS is like 10C cooler than my 3700+ was (with IHS but it was a "cool/cold")...
