This is interesting as heck! I cant wait to get time to play with the E6600 I have been running on D7 since the 4-5-08! that would be 3 weeks come tuesday and from the looks of it I will start my testing/playing that afternoon. I will make note of all load temps before I start. I cant remember exactly what temps were before I took the chip and board to the barn but I can tell you I was happy because temps dropped 2 or 3 degree
