Sups my peeps....

So I just saw a thread with some guy, a TEC and a watercoling kit. It got me thinking.....would it be possible to add a bunch of TECs to an external radiator and if so...what would the effect on water temperature be? You could possible use some of that thermal goo, the stuff used for koolance HD coolers. Hrmmm.

you know............because that WOULDN'T cut your rad's surface area down to nothing.................

i suppose that in theory, you could get a whole bunch of small square peltier modules, and thermal epoxy them all with their cold sides along the flat tubes of a rad, and then thermal epoxy some copper plate onto the exposed hot sides of the pelts, then solder the cross-connecting fins to the plate sides.

it would be a logistical nightmare: you'd have a hard time finding a rad with appriopriate spacings between the tubes, and thermal epoxy crystalizes if it gets too cold, and the thermal transfer between the peltiers and the fins would not be very good, and there would probably not be enough surface area do dissipate the combined heat of the peltiers and the coolant.

this is whay people either use TEC waterchillers, or TEC waterblocks, if they are going to do TEC at all.
 
chilling a res is possible, much more than trying to chill the rad.

that being said, though, it is still uite a royal pain in the arse.

you'd need HUGE fins to cool the hot sides of the pelts, and probably some kind of fan rigged up to circulate air.

better to go with a hot water loop and a chilled water loop, bridged by two waterblocks, with a pelt in between.

something kind of like this: http://www.swiftnets.com/products/MCWCHILL-452.asp
 
I think it might have its merits, but you would probably want to have a single line or two of TEC's at the side of the radiator that is outputting the cooled water. Try it out and let us know! :) Something else you might want to try is to submerge your radiator in chilled water. Ask Erasmus about it.
 
IMO, it much more effective just to slap the TEC right onto the processor.

If however you dont want to do that for some reason I would say your two best bets are to do something like the Swiftech Chiller unit linked above, or to do what Top Nurse said and to submerge your res into some ice water or something (poor mans chiller :) )
 
I thought there was someone of this board who used a custome make huge waterblack, an array of peltiers and a huge custom heatsink to do something similar to what this guy is talking about.

Like there were like 6-8 high power pelts undervolted to 6 or 8 volts sandwiched between a huge waterblock on the cold side and huge heatsink on the hot side.
