So, given that, whats the diference between having a pump and having fans? Its not a passive setup, its not a silent setup, its just pumpless. If it was pumpless AND fanless, now that would be something. But its not.
Joe didn't just chose to remove the pump for noise, but also the high cost and failure rate of pumps.

2. I also don't like the radiator/condensor. To me, as per that pumpless-peltier rig, the radiator should be single pass, and have the "hot end" raised slightly to the "cold end".
Single/double pass doesn't strike me as too important for this. In fact, single pass sounds like it'd be worse because of the tubing required to get to the other end. I don't think the idea is that the water will go in one end and exit the other, but rather some water will enter and some will exit from barb A, and some water will enter and some will exit from barb B.

3. Similarly, the waterblock is curious in its design. The inlet and outlet barbs are on the corners. I would have thought the optimum design would be for a vertical-motherboard orientation, with the outlet barb exiting parallel to the motherboard, or at least at 45° ala Swiftech MC6000's. The inlet would then be below the "contact" area.
I'd think that both the inlet and the exit should be facing up at 45 degrees from the MB, in the same direction (up).


What I want to know is if having two hoses is necessary. It seems to me that having one, larger hose would do the job better, take up less space, cost less, and reduce the failure rate.
