NM on my Edit, I have a Thermaltake Polo 735 ( was thinking I had a Volcano because when I bought it the store clerk said he had a Volcano). I did remove it after the first install, when I desided I had put too much thermal paste on it, I removed most of that as you barely need any at all I'm told. I'm running the HSF on manual fan control, and I have it up at top speed which is 5500 RPMs. My Chasis temp stays about 30C all the time.
At first the Processor was running at 68 - 70C just idle, that was before I removed alot of the thermal paste, now it is in the 60 - 65C range, but I still feel thats high. There doesn't seem to be any stability issues, so I'm not really worried, just bugs me sometimes thinking about it, and would rather it didn't run so hot.
Oh, and when I touch the copper part of the heatsink, it's not hot or anything, barely even on the warm side last time I tried (I don't think I had had it running for long tho). And that 60C is what it is at right when I start up my computer.
