EVEN BETTER!!! (what i use)
1. Purchase cheapo hs+fan (or just fan), same size as your stock, but that runs at higher rpm and blows more CFM. 5500 rpm would do.
2. Unscrew your stock fan, replace with faster one
3. remove the thermal pad, add arctic silver instead.
4. put it on
5. Enjoy another creation of imagination!
P.S my stats:
(I got an amd 2600+ with 333 bus)
1. Stock fan+stock sink+stock pad ran at: 44idle, 50 busy.
2. Stock sink+arctic silver3+6500 rpm fan - 40 idle, 44busy.
Same room temp, location, etc.
