Here's my first attempt at a chiller

Check it out. Still have some changes to make. Finally got it built and installed into my case and testing it now. So far, it will go sub-ambient but I haven't insulated my cpu or mobo so I turn it off when it gets a couple degrees below ambient on the higher 2 cores (22c 22c 14c 14c using realtemp). This is with no load on the cpu, with a light load it will jump to 35c-40c. not ready to torture test yet I don't think. Also, I'm using a Q6600 at 3.0ghz (haven't built a new rig in about 4 years now).

If anyone has any questions or comments, feel free to post.









Update 9/7/12: I'm happy to report I have changed the configuration of my loop to waterblock/pump -> chiller only and it is performing great! Idle temps are 12 12 5 5 and after 1.5 hrs of folding temps were 38 37 29 29. Read on to see the pics and explanations. Thanks for the interest.

Here's a pic of it now:

Yes, 2 tec's drawing heat out of the liquid filled res. I have 13' of 1/4" copper tube coiled up inside of the res and the res is filled with 75/25 distilled water/antifreeze. I'm using Feser one fluid in the loop. The tec's are CP1-12726, which are way too much for my power supply to actually handle (meanwell sp-320-12), running them at 9.2v, maxed out the power supply capability at 10.5v during testing w no heat load. I originally had 12709's, which I may be switching back to this weekend for testing since I never actually tested them. That would let me mess w the voltage, plus the meanwell is getting super hot!

Pumps in the loop are the built in corsair one and the pump that's built into the xspc 5.25" bay res. Not very powerful by any means, but the only reason I've built it this way is b/c I had most of this stuff laying around. The plan is to build an actual w/c loop and incorporating the chiller. Which I will probably do in 3/8" tubing, so I may need to build a new res w 3/8" copper tubing inside. Oh, and I turn the fan off on the rad when the chiller starts dropping the temp on its own.

The loop is cold to the touch, but I don't think its removing heat well enough from the cpu bc of the corsair h50, which is prolly obvious to you guys. Oh and I got as much air out of the loop as I possibly could. Their is prolly a very small amount trapped i the rad, but I did spend quite a bit of time getting the air out (went to bed at 2am that night).

Thanks for the interest, glad to see you two taking notice in particular.

Oh btw, I haven't learned how to do the math with tec's yet, I just started building away! Would the 12709's work better in this application?
I have a ton of pics also if you guys want to see more.

Testing:


Added a relay to the meanwell psu so it will turn on and off with computer:


Here's a filthy corsair H50 waterblock, just had a feeling I needed to take it apart and check it before installing it:


115v power in and switch for meanwell psu:

Wow man thanks! Can you point me in the right direction to learn how to calculate all that as you just did?

So far they're creating a good foot warmer.

What do you think about this chiller in an actual (good) water loop? I've got a wishlist going on frozencpu that I will prolly purchase soon.

Also, it looks like I'll be swapping tec's to 12709's this evening...

Awesome, will have to read that a few times. Thanks.
