I've had some experience with passive radiators in my water cooling setup. Been running two 10' lengths of 3/4" copper tube connected in series with no fan on them for about 6 months. The CPU temps stay 20-25 degrees C above ambient. The tubing rad seems to reach a state of temperature equilibrium after running the computer for about 30 minutes.

My first attempt at passive had 4 shorter lengths of 3/4" tubing with fins soldered on, but the fins didn't help the cooling much. BTW, my rad is painted black. Not for extra cooling, but it just looks better that way.
