Want the cooling benefits of the IO board but without the extra features and price? Purchase a PCB fan board. It comes with a heatsink (the same size as the IO board), as well as a 5V fan.
The fan comes pre-terminated with dupont connectors that plug into pins 11 (red wire/5V) and 12 (black wire/GND) of either GPIO 0 or GPIO 1 header. See page 27 (PDF page 28) of the user manual for the pinout.
The board is mounted using the screws that came with the de10-nano.
This is the TOP plate, fan and heatsink only. For the BOTTOM plate, go here.
- Top: Install heatsink, then use the four screws that came with the de10-nano to mount the fan board.
