The heatsink came in on wednesday, so here's some pics for those who are interested:
So far on my system that's running with no case fans (for noise purposes)besides the power supply, and on a Abit IS7 board with a P4 2.4b @ 3.006Ghz at default voltage I'm getting a idle temp of 41C and load temp of 56C. This is at a ambient room temp of 70F and mobo temp of 32C at idle. Definitely a improvement over my stock coolermaster heatsink I had before, but only by around 5C. I'm also using the packaged white thermal grease that came with the heatsink. Do you guys think these temps are about right or are they a little high for what I have?
