Brent I have spent some hours trying to find a waterblock that would fit the existing cold finger setup. The idea is the water block would cool the hot side of the TEC, replacing the current heatsink/fan combo, and the pump and radiator/fan would be off the scope. Rowland did some heat calculations for me. If I go through with it I would be using CPU water cooling components and not aquarium stuff. There are plenty of water blocks on the market but finding one that is not overkill on a 40x40mm TEC is not easy, and it has to be light. I also need to find one with side hose barb entry so the hoses are not pointing outward. The water block maybe the hardest thing to sort out. It would be a closed system, using soft hoses that won't restrict mount movement, guiding, etc. should be no more an issue to manage than dew heater cables - hopefuly.
