Less heat means less power draw.

lol it's the other way around, less power draw = less heat

He´s right...LESS HEAT = LESS POWER CONSUMPTION

the electric resistance drops on colder GPU = lower power

a hotter GPU needs more Energy for same work as a cold GPU

Yea if it's supercooled with nitrogen or something lol a few degrees c aint gonna make you use less power.

no need for exotic cooling. Any liquid cooling solutions will easily bring the GPU temperature by 30-40C or more depending on the block / gpu.
not only this is noticeable reduction power draw in general, but this is especially true when we're talking about a rig working 24/7. Helps with the life of the GPU and it'll make the PC a lot less noisy.

(just in case noobs with AIO coolers for their CPU come in claiming there is no 30-40C difference between their air cooled CPU and their now liquid cooled CPU: we're talking about GPU's here and that's completely different (if you don't know, just read about how widely different CPu and GPU thermal fluxes are).

So the water cooling uses no power then? I really doubt you get lower power draw just from water cooling especially taking into account the extra wattage from water pump and extra fans not in a measurable way.
