Custom TEC water chiller help

post #1 of 4
Thread Starter 
ok so im considering building a water chiller for my current loop basically it would consist of a radiator 240mm or 360mm cooling the TECs and a custom pair of blocks to run the water through. The water chiller would be a stand alone enclosed unit that would connect to my existing system.

What i would like to do is use my current 360mm radiator to pre cool the water going into the chiller and have it go directly from the chiller to my cpu block

so it would go
rez-pump- rad- chiller-cpu rez

so here are my questions

Q1- would this even be efficient enough to warrant the cost of building it or would it not chill the water enough to get the temps im looking for

Q2- assuming it will work what size TECs would you recommend I want to chill my rediclously hot FX 8120 8 core at high voltages nothing ridiculous but well over my watercooling loop

Q3- How thick should the blocks be to maximize the transfer of heat I will be custom making the blocks out of copper with acrillic tops

Q4- would the spare FSP 500w ive got be enough to power the whole set up

To start you can't put a radiator in a loop with the chilled water because it will just warm the water back up to ambient.

A1: Tecs run most effiecently and perform best when running a cop of 1 and this is around 50% of imax
A2: there is not a single tec solution for chilling a high wattage cpu > 200watt as your describing I would recommend 3 to 4 of these and run them at 12v
A3: 3mm-12mm depending on design.
A4: depending on how many tecs you use 500 watts won't cut it.

Also I'd recommend a radiator setup to cool your ~800+ watts @ < 5c for maximum performance of the tecs so size your rads accordingly for cooling the hotside of the tecs.

Check out http://www.overclock.net/t/1203632/3200watt-qmax-8-tec-chiller-setup-for-1200w-rognin-build will give you a good idea of what a chiller I described above will do

thanks for the information that thread had a lot to take in. Im trying to decide which route would be better to go Phase change or a TEC water chiller

cooling 800w of power would require several large radiators and im not sure if it would even have the cooling power im after

it looks like the TECs do have a few advantages tho one big one being i wont have to insulate my board

Well that is you build a controller to keep your water over dewpoint. I personally don't run tecs without a controller because I don't insulate.
