If it's true closed loop (i.e. no water evaporation to cool the loop) then how are they cooling the radiators without fans?
Honestly, if there is a place it would have made sense to do evaporative cooling it was probably Michigan anyways... but I hope the closed loop option ends up working out just as well.
