Heat will transfer through bonded metal much better than with thermal grease...my logic is to use as little grease as possible...

alives, you are right in the fact that the tighter two objects are together, the better the heat transfer. However, you have limitations that you have to adhere to. First is the fact that you are not pushing two metals together but rather one part metal (waterblock) and one part ceramic/silicone (cpu slug). If you are breaking the clips off, then you are putting too much stress on the cpu anyways. And since there is only a certain amount of pressure you can use, then that is where the grease comes into play. In all actuality, you can throw a glob of grease in there, and when you apply the waterblock, the excess is squeezed out. The smoothness of the slug allows the excess to flow right out from between them. Too much pressure not good. Grease = unavoidable. =]
