Added the 60Hz MD-30RZ above.

Predicted in-line heat is 63W based on 50Hz MD-30RZ results.

Iwaki MD-30RZ @ 60Hz, 11.7 LPM, 0.038, 0.155 (estimated block C/W @ 11.7LPM)

Work out roughly to:

CPU = +15.5C above water temps, and Water = 163 * 0.038 = +6.2C, for a total CPU temp of +21.7C above the ambient air.

If we factor in that the pump is dumping all that extra heat into the room, the room would be warming up as well. Overall you'd be just as well off as with an Eheim 1250.
