I never did watercooling as at the moment I don't have to much cash to throw away for which I believe will only give you slightly better temps then good air cooling.

But I have been thinking... let's say you build a WC steup... is it possible to place a pelt on the rad/heater core to cool/chill the water and I dont mean make it really cold to the point of condensation. All I'm saying is it possible to make the temps around 15-20C? That should not cause condensation?

It'll make the water just a tad cooler with the smallest pelt or something? How does this sound?

How do you cool those pelts then?

Really though, you'd need to ditch the radiator all together and use something similar to another waterblock but in reverse for the pelt.

Using a pelt to chill water is pretty inefficient, and will cost quite a bit to power.

I'm doing something similar to this, making a pelt water chiller. Condensation will occur at different temperatures depending on the humidity. In very humid air, like where I live, you will get condensation on anything even slightly below ambient. In dryer places you can go well under ambient with no problems. Here is a chart with % relative humidity along the top and Ambient temps along the side. The dew point, or temperatre where condensation will occur is listed for every temperature and humidity.

not enough cash to pay for WCing

but enough cash to pay for 144kwh more per month...that's $120 a year in electricty

wow, I never thought of it that way. I read that if you apply heat to one side of a pelt and cold to the other that you can generate electricity. I'm wondering now if you do the opposite of what everyone's doing here and take advantage of extra cooling, if you could make your own little temperature operated powersupply? hmm.... :-/

pelts do work this way generating electricy but not many volts and current is low

unless your using tecs in a water block it wont work very well at all.
you would be better off making a chiller out of a mini fridge with a large res
the power supply alone for peltier would pay for the water block
