Hmm. Yeah, I think I may consider an HSF upgrade in the future. Then again, it's a hassle, and if I don't plan to overclock at all, maybe I won't. How do you go about increasing the voltages and such? BIOS? I heard about people painting bridges and stuff. What does that all involve?

Yeah, right now I just have the retail HSF and one case exhaust fan in the back. Do you know what size the retail fan is for the XP 2100+? Would I be able to overclock it at all with that fan and heatsink?
