Coralife light fixture not working

I don't think their lights are really as solid as they seem. I'm currently having issues with my LED's flickering on one similar to yours.

But as far as the fan goes, it's really important that you have a fan cooling your lights. Your fan probably went out and it caused the end caps to overheat or bulbs to burn out. I think they're 40mm fans, easily purchased at most computer stores for a few bucks. If you have a multimeter test the wires running to the fan, it should be in the 12v range.
