Well here's my progess, after reading that article on clamping pressure I am wondering how I am going to attach the heatsink/fan to the peltier. I certainly can't drill through the peltier without causing some damage to it.

I am guessing I will have to sandwich it inbetween the heatsink and a waterblock and use some screws to apply pressure.

I am planning on using some plexiglass mounted to the bottom sides of the heatsink fan. What is a permanent adhesive that can withstand over 20lbs of clamping pressure? I chose plexiglass cause of the inexpensive cost and because it's not a very good material to transfer heat so it wont interfere with passing heat to the screws and inadvertenly to the cold side.

I've thought of this idea for sometime and the conclusion that I drew was that the water needed to have more surface contact with the cold material. Also the conclusion that the fellow who did the sink test drew was that water pulled heat away more efficently than it let it go so the water I am guessing would need to have longer/greater surface area contact with the cold surface and circulated back to the cold area as quickly as possible. So I am planning now to use less than 10oz of water in the whole setup.
