transport fundamentals says a higher grit (smoother) flat finish will have better contact and better heat transfer.
I'd also say it could have to do with what type of TIM you're using. If your TIM is too thick that it cannot stay in the holes I'd try some different stuff. Using Zalman STG-1 I can get the paste incredibly thin and still have full contact.
@mailman2: Nope I definitely haven't been lapping procs very long. But I'm still going to argue that I could achieve better results from a smoother finish.
I have a few ideas to test my theory with.
