The only way I can think of to getting that CPU cooler would be to replace the thermal compound, heatsink/fan all together. You can get this:
ZALMAN CNPS7700-CU 120mm 2 Ball Cooling Fan with Copper Heatsink
That thing is really, really big, but I feel it will do an excellent job of cooling down your CPU. If you look at the picts closely, I think it comes with thermal compound already. Just make sure to clean the thermal stuff off of the CPU before applying the new one.
