Have you looked into diy chillers? There are some options out there for using old dehumidifiers (good for larger tanks), but there are a lot of explanations for peltier-style coolers (the same style used for liquid cooling CPUs) that should be more than enough for the 3 gal tanks.

For a lot of us, those options are overkill, but it sounds like you're concerned and are working under some extra constraints.

Good luck
