I recently got this one
http://www.mplex.com/cgi-bin/ccp51/cp-app.cgi?usr...HOME:comp%2Fhsf%2F
works with anything, i use it to cool my Intel P4 3.2GHz H/T
i got it because my old fan broke n made too much noise.
i run this fan on low when i not near PC (if i downloading tlkn on msn etc.) When i'm using intensive games(Counter Strike Source) depending on my room temprature i turn the fan up.
I'd recommand that one easy
Enjoy.
