I have a full water loop already (I will just be moving everything into a smaller case), i was hoping to find something i could add into the loop to chill the water even a little bit.

peltiers and phase change are just heat pumps, you still have to dissapate the heat once you move it out of your loop. Easiest but least effective is to strap a heatsink to the hotside of the tec, and use a waterblock strapped to the cold side to help remove some of the heat.

Krow is doing something similar here

I wonder then, what about doing a 200mm rad for my CPU and GPU with a waterchiller (using TEC) in the loop, and then put a waterblock (cpu block i imagine) on the Hot side fo the TEC and cool that with its own 120mm RAD. the water in the 120MM RAD loop would be hotter and then the cool water would be in the loop that matters, the one running the cpu and gpu.

tahts teh idea of how it works. you have to remember energy cannot be created or destroyd only transfered or moved.... so by using a tech your just movign the heat from one loop into another... the tech side can prob be like 80 degrees tho before it rly matters so you can use less rad space... but you still need to cool it. over all there rly good if you have a direct on cpu type tech (liek mindchillers) but to add into a loop to chill its nto very effective

But i would want it to cool the gpu as well, which is why i wouldnt do direct die.


My loop would look like

RAM - > CPU -> Mobo -> GPU - > 200MM RAD - > Waterchiller - > Pump

Loop 2

120MM RAD - > Block on Hotside of Waterchiller - > Res - > pump

Has anyone done anything like that? Id like to incorporate a TEC into this project somehow, but i want it to benefit both the cpu and gpu. I want it to be as compact as possible and it doesnt have to cool a lot, just better than watercooling on its own (dont need to go below ambient, but as close to as possible)

yep that should work ok.... im just letting you know unless the coolign on teh hot side is good your not going to be able to do to much. i would think if possible to try for a 240 rad on the hto side... it will be a great help as tecs are not the most efficent think yet. If cool is what your looking for here you can always look into building a bong cooler.. they are rly neat and perform well

That would work to a certain extent. Having a radiator in your chilled loop works both ways. It works by using ambient to cool water as well as warm the water if it gets below ambient. This means the best your going to get is ambient temps in your chilled loop

You might be better off doing a direct die on the cpu as well as the gpu if your running something like a 7870 or 670 because they have lower power requirements.

The other option would be 2 chillers and then cool those with at least 2 doubles.

I did a similar build a while back using a tec direct die on the cpu as well as the gpu in a mitx build here

It would be a heavily overclocked 2700k and a 7970 :/

I was looking at some of the projects you posted, What about me just getting a good direct die block with controller with a controller?

I guess the bottom line is im interested in TEC because not many do it, i have no access to really fabricate anything of my own so i would want to buy something for at the very least my cpu and i can more or less plug in and go, that i could just plug into a 6 or 8 pin PCIE connector and be on my merry way. I imagine if i keep my cpu cooler then it would help the gpu a little as well, since the water going out of the cpu wouldnt be as hot

I've actually been working on a list of TEC setups and their theoretical transfer capabilities, run at standard voltages. Keep in mind it's only theoretical and won't preform as good as these numbers show due to inefficiencies in materials.

CoolIT Boreas (5V) 12x 12706:

Delta Qmax Pmax
0dt - 336W - 132W
10dt - 240W - 114W
20dt - 144W - 105W
30dt - 36W - 96W
40dt - 0W - 84W

Scan JellyFish (5V) 18x 12706:

0dt - 504W - 198W
10dt - 360W - 171W
20dt - 216W - 158W
30dt - 54W - 144W
40dt - 0W - 126W

Daedalus (7V) 18x 12706

0dt - 648W - 365W
10dt - 504W - 347W
20dt - 324W - 321W
30dt - 198W - 309W
40dt - 54W - 290W

Krow's Build Off! Air-to-Liquid (12V) 4x 19915:

0dt - 640W - 360W
10dt - 500W - 346W
20dt - 320W - 320W
30dt - 200W - 312W
40dt - 68W - 298W

Mindchill's Build Off! Liquid-to-Liquid (12V) 2x 19928:

0dt - 570W - 336W
10dt - 450W - 317W
20dt - 306W - 300W
30dt - 170W - 288W
40dt - 46W - 266W

EDIT: I would have the cooling systems by Digital Storm in here, but there is zero information I can find on their Cryo-TEC system.

Modular Liquid Chiller 1x/2x/3x 19928:

0dt - 285W / 570W / 855W --- 168W / 336W / 504W
10dt - 225W / 450W / 675W --- 158W / 316W / 474W
20dt - 153W / 306W / 459W --- 150W / 300W / 450W
30dt - 85W / 170W / 255W --- 144W / 288W / 432W
40dt - 22W / 44W / 66W --- 132W / 264W / 396W
