It sounds like i'll see much the same on the new platform, that is until I add a super-hot graphics card perhaps.
My setup would be much as it is now - double rad (2x120mm), 10mm tubing, cpu->nb->graphics->rad->pump - which copes well with my current heat load.
I think 75c is the safe limit when C2Ds start throttling, but for every day use, you dont really want to go there
