They don't overheat. Both tanks are in the basement with ambient temp lower than the rest of the house. Temps in tanks don't go over 25C during the day when lights are on. At night it lowers to 20C in winter, 22C in summer.
The light fixture is not right on top of tank, it is slightly raised (two two-by-fours). Here is an old picture that shows lighting fixture (notice no blooms back then):
I don't know what is too humid. Small tank is 80% which is good for phals and large one hardly gets to 65-70%. Front sliding doors have gaps that let humidity to escape I guess.
For the night I usually (when don't forget) slightly open doors and top lids to create small draft there for air exchange. I didn't have any problems with mold or smells yet.
