KnightElite and I spent all evening setting up the MCWChill. Two hotside loops cooled by large single pass heatercores with 2 120mm Papst 100CFM fans each. With peltiers at 12V and 13.8V (these were the PSUs we had) water temperatures quickly (within a minute) start to dramatically drop. For testing we used a MCW5000-a waterblock, an Eheim 1048, and 3/8" ID tubing and a ball valve to throttle pump.
CPU: TBredB 1700+ @ 2084MHz and 2.00V
Diode temp from epox 8k3a+ motherboard: 12 ºC
Room temperature 23 ºC (but rising)
water temps measured on inlet and outlet side of chiller were 1.90 ºC and 3.45 ºC (with Digitecs)
Some pics of the monstrosity:
My plan was to use the pressure gauge to estimate flow rates, but the battery is dead. Will get a new 9V tomorrow and then update this.
I will play around with the unit for a week or two more as long as Bill doesn't mind and keep this thread updated as more useful (temp vs flow/temp vs voltage) numbers are produced.
