Why do you advocate such a low alcohol to water mix? Isn't the idea to have a liquid mixture that gets as cold as possible before freezing? Hyper salinated water will still freeze at -20c to -21c. I have a bottle of Grey Goose in my freezer which is set at -18c and pours like liquid. What else might work? Ethanol?
Also, until you've personally tested a 226 watt TEC with -20c water cooling the hot side then please don't knock the TEC set up. Gabe Rouchon and Eric (OPPainter) of Swiftech took a 6500T TEC block and cooled it with cold tap water (about 7c) and ran his quad up to 4.037ghz with 1.47v vcore. With mild overclocks on water cooled 8800GTX's that set up landed a score of 20,242 good for 26th in the world in the 3D Mark 06 ORB. With better clocks on the cards and straight water on the CPU and 8800's he managed to get even higher to 25th (20250) in the world last I checked.
So, I figure with colder water cooling the hot side then I will be seeing almost single stage temps on the overclocked quad. My 8800GTX's are scaling pretty ok as well. I think that with LN2 cooling and clocks up to 845/2000/2400 (gpu/shader/memory) I should have no issue breaking the top 20 at this event. Do you live close by? Why not get a ride and come watch it happen?
Nice thing to say, care to share why?
A pelt is pretty stupid....the colder you make the hot side then the colder the cold side gets as it comes closer to it's theroritical delta T. My pelt's Delta T is -26c so if I cool the hot side with -20c water then all the pelt does is get even colder. This is as long as I can feed it 13.8 volts at 25a or so.








Oh and are you sure that pelt will get good results on a quad? It doesn't look like a 226W TEC @ 13.8V (is it?) is going to cut it.
