Do you need to? Without enough gas in space, how likely is it for something even as powerful as a data center to overheat?

You have gotten it exactly backwards. Vacuum is a great insulator, getting rid of waste heat is a huge problem in space.

What do you mean? The lack of 'gas' aka material to dump heat into is exactly the issue.
