Hello
I got TEC 73W (15V) Peltier module. I want use it to chill water in my watercooler. I have one big radiator 160x80x40 (15 fins) for cold site and Titan TTC D5TB cooler (no problem to takeing 75W with ~55C) as well cooling without water peltier isn't problem. But problem is cooling water with this cold site where will be big aluminium radiator. Do you think it can be a good idea? and it will be working?? good. How much preff temp of water (around 1,5l) it can??. Sorry for English...

I think (and I am often wrong, ask my wife) that you are going to have some very big difficulties in accomplishing this. It is rather difficult to achieve any reasonable cooling of water with tecs and with a low wattage tec....well...Have you possibly considered cooling a northbridge with it?

73W is a tad low. I'm quite that it wouldn't outperform an aluminum radiator. With a higher wattage peltier (>150W) you may have a chance of getting good performance, but not good enough to be worth the time or money.

stedman, thats a great drawing, To make it efficient, you need a micro channel block, It does not need to be thick, really thin base and really thin overall height because of the way the heat is spread out over a large surface. The hot side would almost have to be watercooled to make it efficient. Depending on the wattage of the peltiers. You would want at least 1/4" of insulation and instead of adheasive, have it clamped with thermal paste.

The trouble with TECs is that they produce a lot of heat themselves. You then have to get rid of that. Which means large HSs and noisy fans and if you're going to go there you may a well just stick a larger fan on and larger Rad and get the performance that way...
