See that does make sense to me, because you are saying that water directly on the IHS does not conduct heat as well as a heat sync pressed ontop of the IHS with pins... That cannot be correct, it's got to be due to surface area and the lack of with the direct concept. You could compensate so that by bringing the "ceiling" down closer to the IHS after the water enters the area, creating higher pressure in the block.
