The black hole is colder than the average temperature of space. Computation costs less at low temperatures, because temperature is defined as the ratio between the change in the energy and the change in the entropy of a system.
But assuming your radiator is going to be hot anyway (we've got a Dyson sphere to produce all this problematic energy, right?) then surely it's not that big a deal?
Still, it gets me thinking science-fictionally. Are there any stories where aliens invade the Earth just to use it as a heatsink? Travelling around from star to star, dumping all your waste heat into whatever planets you can find -- sounds like a great lifestyle.
