The awkward thing about TEC or Peltiers is that you still need a system to move the heat away from near the device, which often defeats the point. I was looking into using them to cool the stepper motors on my enclosed 3d printer, but realized that I'd still need a water loop to carry the extra heat away, in which case I could've just setup a direct water loop without TEC. In the end I opted for just heatsinks with fans pointed at them.
