There is an ongoing discussion in a swedish oc forum (sweclockers.com) about how efficient direct die cooling is and that it should be alot better than using something inbetween to spread the heat over a larger surface (ie. a waterblock).
There is a claim that cooling a peltier with the same technique should be better too...
I just wanted you all to vote for the most efficient way of watercooling something hot.
Please post pros and cons about the diffrent cooling methods that might come in mind.
