Alright, so i came home tonight to find a tank that was almost 83 degrees

Some of it may have to do with the PC lights which are 5 inches off the waters surface, but i feel that alot of it has to do with the poor ventilation in the stand. What does everyone out there do to make it cooler down there, because I am assuming that would make it much cooler in the actual tank. I know some people use computer fans, but i would be confused about how to power them. I would also like the most quiet solution there is, since i sleep 10 feet away from the tank.
