Well, to really answer the question we'd need to know what you've got for a heatsink/fan right now. I see you mention an Intel fan, but to the best of my knowledge Intel didn't make fans so it's likely the stock HSF that came with the chip. I've got a Taisol CGK742 that's working just fine (I've beefed up the stock fan to about double the CFM), other than that you're ok with an Alpha Pal or FOP. If you're looking to compare fan's against their noise & cfm, then go to:
Gizzo's Fan Page
He's put together a fantastic listing of fans and all the pertinent info that goes with them.
