well a little weekend undate.been running unit on and off all week.well today (sunday) i set out to try and load up the unit with a 156watt pelt on the evap and 80watt pelt on the chiller.well middle of the week i changed the capillary tubbing and made it longer to help bring down the temps while i was using r502.seams i set the unit up for r22 capillary and r502 flowed too easy,more than i expected.making the evaperator flood with excesive refridgerant.this makes the temps rise it would get is about -44f on the evap.but because i am running dual capillary tubes one feeding the evaperator and one feeding the is very hard to get the best of both the chiller and evaperator block temps.get one good and hurts the other,,so i have comprimised to come up with a nice in the middle setup.i lenghened the evaperaor block capillary tube to 120" od .036id tubbing. and set the chiller to 90" of .031"id this hurt by load temps with a 156watt pelt.evap block cannt keep up with the heat load.rises to about 32f(0.c).but then again no cpu will put out that kind of heat.but the chill did very well with a 80watt pelt on load.keep temps around 24f (-4c)in the coolant after a couple of hours of running.

overall the cooler is working pretty a no load temp of -52f (-46.6) on the evaperator cpu block and a -11F (-23.8c) in the chiller tank.chiller is taking 2 hours to reach -12f(-24c) and has a reservoir of 2 gallons.
