PLM, I don't have a fan on the heatsink. I took a retention clip off of an old K6-2 or Celeron heatsink/fan and bent it a bit so that it would fit snugly over the zif carrier card heatsink. (it is too long without bending it a bit) It runs without a fan between 25C (idle) and 36C (under load). The hottest I have seen it at with the case shut is 44C. It ran hotter (70C) when I had the S900 case open. Once I put the side back on the case, it dropped down to the lower temp range. No additional fan is needed directly on the heatsink. I should point out that I have an additional case fan installed in the bottom fan bracket near the front of the S900 case.
When connecting the retention clip, make sure that the heatsink is seated toward the bottom of the carrier card so that it is seated correctly on the processor. The only other thing I would caution you about is to make sure that you are grounded. I have an anti-static grounding bracelet that shipped with my zif carrier card (I think). Since you will be spending about 5-15 minutes trying to get that retention clip connected correctly, you might want to make sure that you are somehow wired to ground at all times. Good luck and please write back if you need more info.
