Yes, i finally figured out what the hell i am going to do with my 130 watt peltier that i have.

I am going to build a home-brewed direct-contact water chiller out of the peltier.

The cold part of the peltier will come in direct contact with the water, so i will build walls around the peltier to box it up, I will have one barb going in so that the water comes directly perpendicular with the cold side of the peltier and hits it at a 90 degree angle.

Then i will have another barb that will suck the water out the side where it will proceed on to the CPU.


This home-made waterchiller will be put between the radiator and the CPU, where the water flows like this:

Pump ---> radiator ---> WaterChiller -----> CPU -----> Reservoir ----> pump.


This will give the maximum effective cooling for the CPU, and at the same time if the peltier fails it wont burn out the CPU instantly, i will still have water to cool it down till the over temp protection kicks in and shuts down the entire rig.

oh, and this chiller will be cooled down by a heavy copper heatsink





So, i posted this because of course i have questions, i was wondering if the peltier might become porous or something as would a CPU die when attempting direct-die cpu cooling.

Any other flaws in this plan that anyone can see?

i dont think that 130 watts is enought to make a real difference in your temps. two words: evaporative cooling. for the same amount of effort, you could drop your temps without using signicantly more electricity. and youd probably get better results. that said, youd be better off using a heatsink on both sides. use a cheapo aluminum HS in the water and a good one on the hot side. that way you dont have to worry about the pelt degrading in water.
