I here you on the more pressure, in order to squeeze more goo out, so more actual core/sink can touch. and that I fully understand and completely agree with..... BUT more pressure does not result in better conductivity..... It is the better contact that give results.

What I'm saying, is that you do not need to put more down-force on the chip, than what is required to get the perfect seat. once that seat is established any additional pressure, is not going to do you any good. I always "TUNE" my blocks, when I mount them. and this is in-fact what I find when doing so......

Tuning a block, very similar in procedure to torqueing a cylinder head onto an engine block.

I find that I can apply pressure to a point, where my temps are as low as they seem to want to be, I play with the leveling of the block, to get the perfect seat, then I can go tighter and tighter to my hearts content, it does not do a single thing for heat transfer, nothing, other than getting me all jittery and nervous. the optimal tention I found easily obtainable with tightening the nuts with my fingers.
