Is the heat from the CPU and backlight really that significant?
It's not huge, but it's better than nothing. The backlight is the biggest power draw in the system so I think it raises the internal temperature by a few degrees
And you don't really want it powered any longer than required anyway because if it's powered while wet you get more corrosion on the PCB.
