I ran the thermal calibration - it failed saying the CPUs (both of them) have exceeded the maximum temperature. The machine is totally clean - no liquid, no stains, no residue anywhere. The seals seem solid. I don't believe that it's been leaking as in dripping out. Could it evaporate

My Dual 2.7 with either the Delphi or Panasonic LCS at idle is about 155 F equally between A and B. However they will vary 30 F between CPU's and top temps at 185 to 200 when loaded. That seems really high, but I've never used a dual 2.7, so maybe their higher clock speed ==

My temps run about 65 to 75 most of the time. We had a heat wave two years back and the temps in the condo got to 115 F. That made it leak. Ugh. Glad to have central A/C here in the foothills. Well my Dual 2.7 power draw may be due to the 5 2TB internal HDD's , they keep the fans busy,

Hi all! Wouldn't it make sense for CPU A to be hotter than CPU B? I don't know much about hardware, but if Mac OS X (or any PowerPC OS acutally) uses threading, isn't it possible that frequently used threads are allocated to CPU A? Or, maybe more sensible, CPU A just happens to get most threads?
