Well, a few ice cubes in an aquarium is probably 1% water from the cubes and 99% already warm water. I don't see a problem. I've put ice cubes in fish tanks before, a few cubes in a 20 gallon (75 liter) tank. Put a thermometer in the water, and you'll be surprised that a few ice cubes don't cool the water very much at all. Anyway, water in the wild isn't uniformly a single temperature, it varies.
A better idea, I think, is to have a fan blow air across the top of the tank. This increases evaporation from the tank water, and that evaporation cools the water.
Society finches, if they are indeed domesticated Lonchura striata, evolved in (mostly) tropical areas. They should be able to take the heat.
