Here's the overall view of the unit. A high speed fan pushes the air through the perfectly sized radiator, and water flow rate is controlled by a small hand valve.
The radiator itself was horribly filthy when I first took it off, but a quick soak in some warm water and light detergent took care of it.
I placed the fan fairly close to the radiator itself, and it works great. I typically put the fan on the medium or low setting, as I notice little benefit from the high speed setting other than increased noise.
The radiator was almost perfect, it only needed to be raised by a centimeter or so to align with the fan.
To calibrate the valves, the small hand valve inside is first opened wide and the garden hose opened or closed to find an appropriate upper flowrate. Then the hand valve may be used to vary the water flow or turn it off entirely.
The nice thing about this new setup is that all control is now done from inside the room. Starting and stopping the unit is far more convenient, which leads to more efficient water usage.
The performance of the unit is drastically improved over the old design. Less water is needed, and the room cools quicker.
The water first runs through this coil, through the ice water, and then out to the fan
Here we can see the aquarium pump submerged in the ice water. The aim was to increase the power of the pump, and replace the polystyrene container with something more permanent. A small freezer with its heat vented to the outside would be ideal.
