Is there a device to keep the water cool in a fish tank over the hot summer days? - device to cool rabbit cages

I have an aquarium in my house with 2 floors. The tank is above the room with my girls. I fear that the days are warm to the point of 105 degrees, the heat rises, the fish die. Is there a device into the tank to cool the water?
