Welcome to the forums, SupraMan. I went with the Thermalright AX7 with a Delta 80mm fan. It was too loud, so I bought a rheostat to control the noise / RPM of the fan to get a good balance between cooling performance and sound. Be sure to read the HSF reviews on the main page (the link that Iron Hawk gave) so that you make an educated decision. Also, the AX7 is BIG and may not fit a motherboard crowded with capicators.
