It depends very much on your resistor. I've seen some very high wattage resistors with cooling finds that I suspect wouldn't have a problem.

I know I could stick a low resistance across it but that's going to get very hot very quickly. The other thing I'm thinking is to place some 12v light bulbs across the rails and leave it running for a few days with temperature monitoring in place on the voltage regulators.
