I have an AVC Mega-cool hsf that I got with my duron 800. Is this a good heatsink or am I better off get a globalwin fop32/38 or taisol hsf? Right now I have the 800@1gig and at 1.8v. At full load the mobo(epox 8kta2) cpu probe reads 45C, 38C normal, and case temp of 25C. I'm kinda leary of the mobo cpu temp...not so sure.
