400W lights are hot - there is just no way around it. I run 3X400W lights on 2 of my tanks and am always battleing heat. I am going to put a chiller on my 190g next summer as this tank is acrylic and no matter what I do it get's too hot. If you basement is already hot and muggy what you may want to do is to figure out some kind of ventilation or you will probably be dealing with mould at some point in the future.
On my 230g tank that is glass I can control the heat with fans blowing across the sump but it is just not enought on the acrylic tank.
