It fits with no problems at all.
Only thing is that you won't be able to do much with the Northbridge fan because it comes up right next to it. Couldn't put on a Blue Orb because there isn't room after you put the Pal on. While you have your mobo out though, you should re-grease the Northbridge fan. I popped mine off and it had goop in only a small center portion.
Also, be careful when screwing in the bolts in the back. I used a curved set of plyers with *NO TEETH* to screw em nice and tight. I've read a post or two about people cutting traces on their mobos by accident when using plyers and what not with teeth.
Other than that, the performance of this HSF is awesome. Its about 1/2 as loud as my old Delta 60mm 7k rpm, and seems even quieter b/c there is no screech/whine. Also, my temps are much cooler. A combo of the XP compared to my old 1.4 t-bird, but still, 35C and I'm running my XP at 1653mhz.
