Considering adding a 92 watt peltier to my cooling system loop but I would like to ask advice.

Hey cooling experts, I need some information and avice! First, if I understand the principle correctly, the peltier get's really hot on 1 side and really cool on the other. I have been planning and collecting hardware for my 1st custom loop for about 3 months now. Been taking my time, trying to learn all that I can and taking care to select the right products. Is it correct that I don't want to put the hot side towords my loop to cool it because it will in turn add heat while adding cool. My 1st thought was to cool off the hot side with air, but I threw that idea out the window.quiclky. My idea is to use an Antec 920 clc that I have laying around to take the heat away. If I was to mount the rad in my rear 140mm fan exhaust spot, then it wouldn't mess up my design much. I could then, pick up a used, cheapie copper h2o block, and put the cold side to it and add it to my current cooling loop. Then put the 920's pump/block on the hot side to get rid of the heat. In theory, it will get riod of the heat much better, and much more consistently, right? I hgave an extra xigmatek hard drive cage that I could use to mount it all in, and place it somewhere outta sight.If any of you all that know what ur doing with these peltier's could let me know ur thoughts, I'd appreciate it! Thanks.

My current setup:
Elysium case
Asrock Z77 Fatality Professional
I5 3570K
Corsair Dominator 1866 4 x 2gb with gt fanms
Twin H.I.S. HD 7850 2gb cards
Hauppage TV tuner
Swiftech dual 140 quiet power -- Black Ice triple 120 copper rad
Enzotech cpu block and compression fittings
Swiftech 82 gpu blocks
6 Universal vrm blocks to mod for memory on the cards and on the mobo vrm's
Swiftech maelstrom res w/ mcp 350 pump inside, and 2nd mcp350 as backup pump

I wouldn't even start to consider peltiers with only a modes loop like that. It only starts to make sense to use peltiers when you have exhausted the cooling potential of just water. Peltiers have a lot of issue like first off. It uses in this case 92 watt of power. That's 92 watt of extra power draw all the time.

Then there is the issue with condensation. Either you will have to make sure the peliter is only turned when the temps are above ambient. Drop to sub ambient and your system can fry due to condensation. Another way is to condensation proof the components with lacquer and grease.

If you still think going exotic cooling is a fun pass time then go ahead. Its worth remembering though that peltiers don't add cooling they improve heat transfer so to get any improvement at all you need to either have the peltier on the CPU or have enough peltier power to drop the temp of an entier separated loop.

Now, this is exactly the type of information and candor that I have been looking for. I understand condensation, but in the dual loop diagram, I'm assuming the cold side is exclusively cooled by the peltier, as the radiators will actually warm the colder h2o back up to ambient, correct? All of the radiator cooling power should be dedicated to the hot side and taking the heat away... is that correct? I surely wouldn't just throw something in a rig that I currently have 1400.00 invested in, that's for sure, but spending 12 bucks on a smalll project that may or may not materialize is def. my style lol. I got a ton of gruff when I was troubleshooting the 2nd mcp350 pump in my system to only be as a redundanty backup, and got her done... just the challenge of it is what keeps me going. The idea first came when a friend offered to sell me what he called a "chiller" which appeared to be about a 6 x 6 chunk of heatsink and wires with two 1/2" barbs on it. That led me here.... Thank you for the information and honesty, it's refreshing.
