Do you have a heat problem at 6"?

Rarely, maybe once or twice a year will my APEX shut the lights down because the tank gets to warm. It has to be above 27/28c outside for a few consecutive days before the basement starts to warm up to the level that the lights push the tank over the edge.
I was more concerned with bleaching and such.. I'm running 2 IC 10k's and 1 IC 14k
