jediphx, big negative on using the GW FOP32-1. It was made with the earlier duron/athlon in mind up to about 1Gig. With an XP1800, you'll want to go with a copper hsf. I used to use a fop32-1 on a duron650 @ 866, lapped and AS. But the cpu would push approximately 50C. An XP 1800 will pump out about another 20-25Watts above what my duron was doing, so you definitely need a better hsf.
