I used an heatsink and fan from an AMD Athlon processor. It fit perfectly on the pad, and has many thin blade fins for better cooling. I don't have the dimensions at hand. I will try to get them for you after work.
The contact pad on the bottom of the heat sink is the same size as the OEM heat sink on the HU, but the fin area extends over about 0.5"....
