This is where some are getting it confused and that other website introduced the myth. I lack the proper education in this area to explain it correctly though. It's a matter of lowering the thermal resistance and using turbulance,velocity plus flow to take advantage of the water as much as possible as it passes through the block - same thing with a rad. Water only heats up so much in a given amount of time. Some water blocks have to heat up more before it can transfer the same amount of heat to the water as a block that doesn't have to heat up as much. This is why copper is far superior to aluminum but they both transfer the same amount of heat to the water. The heat just travels through copper and into the water faster than aluminum. This is one reason why copper is used more often in electrical applications. Electrical resistance has pecular effect - Heat. Copper can deal with this heat better allowing more electrical current to pass through it faster with less resitance.
