This is a question I ask myself all the time. Then I'd typically ask Stephen to put a high end heat pipe in the chamber for baseline testing, and always end up in favor of W/C by a long shot. At equal low noise level and a conservative O/C, a top-end heat pipe might get you close to the W/C CPU temps but you will never drop your GPU temps by the 20 to 30C like we see in a W/C loop. My EVGA was reaching 80C with the stock cooling and dumping massive amounts of heat in the case. Now I'm hovering in the mid 40's with case temps close to ambient. What do you make of that?

Water cooling is no longer just CPU. It's a system, dropping ALL the critical component temps. That's how it has to be looked at.
