I've seen lots of stuff about water cooling the processor/ram/video/hard drive inside computers.

What exactly is inside the "cooling block" that is placed on top of the processor/etc? I'd like to fashion something similar to sit on top of the amplifier that powers my car stereo set cuz it gets HOOOOOOT. It seems that all the cooling block is is a sealed container with an open bottom and input/output on top for the water, am I incorrect?

Has anyone else already done this? does this product already exist and I'm just lookin in the wrong place?

TIA

You are correct that the water block just contains an channels that the water passes through and takes the heat away from the block (which pretty much acts as a standard heatsink aside from this). I've never heard of a block big enough for an amp.... but I've seen a few projects from people that have water cooled a serious amount of PC parts. From what I've read about water cooling projects you do need a fair amount of milling and other specialist equipment to make good blocks. I can suggest that you take a look at ZeroFanZone.
