I'm running a Vantec
FCE-62540D too. I HAD to pull the fan that came with it also, it was just TOO LOUD. I replaced mine with an ADDA
60mm fan. It's nice and quiet now. And still does a great job cooling.
The clip is very easy to fasten. And by this HS being so LARGE it also makes it easy to lapp
All in all, there may be fancier, colder cooling HS/Fan combos out there. But for the price, it's hard to beat.
[Edit] My CPU temp is very good. Now all I have to do is cool this Voodoo5 down somehow. Even overclocking a P3 650 @ 910, it's my video card that's the "heat generator" in my case.
