I went full out and bought an Alpha PEP66 from Plycon . This heatsink is a monster. Notice all the fins, their large surface area is great for disippating mass amounts of heat. Also note the way the 27cfm fan is mounted. The PEP66 also has a nice copper base where it touches the CPU core.
Copper is better than aluminum for transferring heat.
The mounting clip is very good and keeps the heatsink nice and snug with the core. Those nice little feeties keep the heatsink from being pulled one way or the other on the slotket. Abit makes the best motherboards IMHO and all their products are built with the overclocker in mind. You can't tell from the picture but the socket handle is flush so it doesn't interfere with big heatsinks. All rights reserved.
