Yes, and it's easier to cool things on earth. In space, there's no air to help you cool thinks off, you can only reject heat through radiation. Most spacecraft are carefully designed to reflect heat/light on surfaces facing the sun and radiate heat into empty space from surfaces that are shaded.
What if you build it on an asteroid or moon or planet. Uranus is ~-225⁰C, right?
Yes, but the two-and-a-half hour lag each way would be a killer.
My understanding is that these "datacenters" would be used exclusively for model training, where latency doesn't matter.
It is still an outrageously stupid idea for a zillion other engineering reasons, though.
There's also the issue that around once a year the two planets will be on opposite sides of the sun. Not only would you have a lag of close to 3 hours, but communication would be completely impossible for a month or so at a time.
