Peltier Cooling Water in Loop

Hello OCN,

I'm wondering if anyone has tried to use Peltier to cool the water in the loop. The concept is the rad would cool to ambient temps, and the Peltier would cool it below ambient.

Would this even produce enough of a temp change that would affect performance or even require less rads to achieve similar performance?

The science side of me makes me think that it would just even out, but what made me think that it would achieve different results is that the cold being directed to the water temps and the heat from Peltier being dissipated into the ambient temp would direct the colder temps to where we want it.

Regardless of whether you've tried it or not, I would like to know people's thoughts.

Peltiers suck. Don't waste your money and time.

For a system that combines radiators and peltiers the rads would only serve to stop the Peltier from being able to achieve anything.
A cooling loop doesn't really have a hot and cold side. The whole loop warms up until the rads are warm enough to dissipate the wattage the system is generating. Its always natural to assume that hot water comes out of the water blocks and ambient temp water comes out of the radiators but that's just not how it works.

Hmm, ok. I do think the rads would OP the peltier. I was thinking by separating the hot of peltier from the waterloop, i cant create some net gain on the water side, but yea, it's more of a macro system that micro things won't affect.
