Heat sink

Heatsinks are thermally conductive objects placed on a circuit board to help cool it. In conjunction with a fan, a heatsink prevents overheating. In the RepRap community, heatsinks are most commonly attached to stepper drivers (Pololu, StepStick, G3D driver, etc). This is done with a thermally conductive adhesive or tape.
