This is an interesting idea but from what I know carrying computation in the space just because it's really cold might not be as good as it seems: space it's almost empty (not really a vacuum but with very few matter). This means that in space you can't really loose heat by contact but only by emitting infrared radiations. This means that although space is really cold an object put in space will take some time to cool down. Correct me if I'm wrong but given the fact above I don't see a clear advantage in using space as a heatsink.
