What you are seeing is true. I lost about 42watts per 7970 while switching to water cooling.

You can see my results here: https://bitcointalk.org/index.php?topic=57410.msg683755#msg683755

Yeah but he's talking about 50W per card. Do the stock fans really consume that much power? I have a full size box fan that doesn't even use that much.

It isn't the fans, it's because of the GPU die leakage at high temperature. The phenomenon is much more pronounced in smaller architectures such as 28nm.

yep
