Just bought a Lab water chiller.. quick questioin

I went through the same problem a couple years back with insulation and whatnot. I went a bit extreme with the insulation per the guides and advice people gave me.
I sprayed the entire backside of the motherboard with Lacquer, then I used nail polish around the entire socket area. Then covered the entire block with foam insulation tape, http://www.grainger.com/Grainger/VIR...ion-Tape-4E309, basically making a little "house" type structure.
And as for tubing, I went with foam tubing insulation. I wish I still had pictures of my setup, I know they're somewhere. If i find them, I'll post them up. It looked like crap, but it did the trick I had the coolant at like -30c all day.
Edit: Found the pictures.

Now thats overkill dude

I don't know if it was the humidity in Chicago or what, but I tried it with less insulation and the mobo+hardware would sweat like crazy, so I did it right for the piece of mind.

sometimes you just got to make it XTREME, very sweet project!

i was using pool antifreeze rated for -20C
and look what happened.. froze solid and had to mash it.. was wondering why my cpu was getting hot.. no liquid was passing through

Just use some car antifreeze and you're good to go.

i mixed some pennzoil in the coolant.. hopefully that takes care of the freezing.. or did you mean replace the entire coolant with car antifreeze?

You may not have had enough glycol in your previous mixture. Pool Antifreeze is typically Propylene Glycol, as you can swallow some of it and it won't kill you. For Propylene glycol, a 60% mixture is preferred as it will give you extremely low temp capabilities and PG is a little better with heat transfer than ethylene glycol. Ethylene glycol has a Specific heat of around .7 at 60% and PG has .8 . Its not exactly a big deal, but worth noting.

I am thinking that you didn't add enough of the Pool antifreeze.

Antifreeze works great / when I was in Japan they had many different colors.... I've ran them at -30C without any issues...
