Is there an alternative for a heater/CHE?

Ok, is there a way to keep a certain area cool easily? I'm basically a newb to keeping BPs

In my case I set my central AC at 86 durring the day and 84 at night. This is the easiest. Alternatives are good air circulation combined with evaporation. A ball that is getting too hot for their liking will often wrap around their water bowl since it is generally cooler than the surrounding air due to evaporation. You can also cover part of the tank with a damp towel which will bring temps down a bit.
