I have found a way to put the pe66 on tbirds and durons. Instead of the fan on the side. remove the cover (the one that screws on the heatsink)set it so the fan mounts on the top. slide it down until it touches the mount clip (the clip that mounts the heatsink and fan to the cup). Slide it up to see where the drilled holes are(the ones on the heatsink), just between the holes drilled in the cover to mark position and drill a new hole one on each side. screw to heatsink. That's it I also cut the legs off the alpha, socket a chips have their own legs.
This setup fits the msi k7t pro2 mother board.
