Let me just...
So, this are the famous TEC elements? Nice!
Figuring out how to do a coldplate with the stuff I've got lying around... Hoping that a 1mm copper sheet will work for the bigger dies (hellscream's X800Pro!
Although I might just slice an aluminium heatsink out of its base
Off to solder a PCIe connector to it! I'm not quite confident on the power capabilities of a Molex
Edit: I'm breaking my brains to design a system that will hold the TEC to the waterblock, so it is a drop-in system (it's a pain to get the block in line with the cold plate in line with the TEC in line with the insulation in line with the die... -..-)
Will go see the local metal scrapyard to see if I find some copper stuff I can make two solid 40mm plates of.
And a quick performance update!
The hot side rests at not-so-cool 51ºC, while the waterblock isn't even 35ºC. I used toothpaste as a TIM, and 5mm of TEC were hanging from each side of the waterblock.
Measured temperature is in those hanging edges, to ensure they didn't go past 60ºC (the red line, this TEC is rated for 67ºC).
I made a cold plate using a scavenged PSU heat shield, out of 2mm thick aluminium. In less than 15 secs of running, a very small tab I left for the sake of temp measuring already had water droplets on it, and in 30 secs it was completely frozen!
The PCB of the card stays at around 12-13ºC, but the GPU doesn't go below 15ºC or so. I'm going to solder two flaps to the waterblock so it contacts those two little hanging edges, and I'll use real TIM as an interface between the layers.
This is how extremely ghetto my setup is, from the waterblock to the GPU core.

I'll use some MX2 later on, see how it improves Edited by Artikbot - 2/18/13 at 5:37am
