well, i personally just used a cheap master cooler heatsink/fan from a computer show. i got it for about 7 bucks. then i stacked another cheap fan on top of the fan that came with the heatsink, it works great. my duron 800 runs 1050 mhz @ 105degrees f!

Ive got a global winfop38 keeping my duron750@950 down around 91 to 93 degrees.
Its loud.
