What to use?

I bought an Athlon XP 1700+ on retail sale from newegg. It came with a cheap AMD fan and I don't feel like trying to overclock using that one. Could someone suggest another fan that I might use to overclock my processor on the rig below? I am currently running the AMD fan with Arctic Silver 3 @ 45deg.C on full load (while folding) Any suggestions would be welcome .

Thanks in advance,

just to let you know, folding is not a good way to get good load temps....Most people like prime95 for that
