@lichyetan, u mean u add 2 adjustable nut there so that u can control the force for contact the block and the chip?

last time when i was using Tt Silent Tower which have the same concept
of the adjustable nut the adjust the force, it really achive great result then any other 'clip-on' type cooler.

i truely believe that using this kind of mounting was the best to achive
perfect thermal contact for the block and chip IHS.
