It shouldn't. Many of us use sumps to store the equipment for our tanks, to include out heaters. The heater for my tank is about a foot under my display without any temp difference. Many others are much further away, sometimes on different floors of the house. Without knowing much about your cube, I couldn't say if I would do such a thing with my heater or not.
I have the jbj 30rl. Looks same as mine, I have my heater in the back.
