I am running a 945 Pentium D and an Nvidia 8800 I am water cooled (just my CPU and I have the following numbers (CU, AMB1, AMB2) idle: 45, 47, 44, and 62, 54, 57. I have a 120MM fan at the front of my case and one in the back attatched to the radiator, then a 140+ fan on my PSU right above (facing down) the rear fan.
