Thanks James and Michael i was just curious it seems i have the highest temps out of everyone i know with dual 500 and can't seem to get them any lower tried just about everything my guess is the heat spreader isn't flat and since i took off the foil it doesn't make good contact with the thermal paste, i have a 4 degree difference between the two processors with MPU 2 always running hotter than MPU 1 at 100 percent cpu usage on both processors i get max temp of 56 c. and 52 c. Guess i will need to wait for Okatu to come visit to fix it for me, don't feel like pulling down my cube again and hopefully one day i'll find someone who can machine the spacers for me because the ones i'm using now aren't correct.
