Magnets.

(We're just saying random physics things right?)

No, just you. Superconductors don’t get hot. There is 0 resistance in superconducting mediums. Theoretically you could manufacture a lot of the electricity conducting medium out of a superconductor. Even the cheapest kind will superconduct in space (because it’s so cold).

Radiation may be sufficient for the little heat that does get produced.

Right. You build your computers out of superconductors, and they don't get hot.

Sadly, they also don't compute.

Is this a drinking game? Take a drink whenever someone claims that heat is not a problem because space is cold? Because I'm going to have alcohol poisoning soon.

Let's see how cold you feel when you leave the Earth's shadow and the sun hits you.

If/when we get high-performance superconducting computers, we wouldn't need to put the computers in space in the first place.

You've invented a room-temperature superconducting material? No?

Didn't think so.

Currently available superconductors still need liquid nitrogen cooling, meaning they're not feasible for in-orbit installations.

Could we use a constant stream of micro-asteroids as a heatsink?

i think so, next is Quantum right?
