	Since the [[ROCK64]] has no PWM pins available to control the fan, a slight workaround can be done; with the <code>gpio-fan</code> device tree binding, an Arduino can be controlled to soft-PWM a suitable 25 kHz signal for the fan. The ROCK64 uses 3.3V on the GPIO pins, so you'll need to logic level convert it to 5V if you're using a 5V Arduino, and if you're using a 3.3V microcontroller, you'll need to logic level shift the output PWM signal as the 5V fan will be expecting 5V PWM on the PWM pin.

	A fan is mounted to it using self-tapping fan screws usually shipped with computer fans; put the fan on the underside of the plate, and screw in the self-tapping screws from the top side. ~~Make sure that you~~ have the fan ~~oriented~~ the ~~right way~~, ~~though this being an open enclosure~~, ~~there isn~~'t ~~really a wrong way~~.		A fan is mounted to it using self-tapping fan screws usually shipped with computer fans; put the fan on the underside of the plate, and screw in the self-tapping screws from the top side. You can either have the fan exhaust air through the top, or blow it onto the SoC's heatsink. The latter configuration appears to work better, but precise measurements haven't been made yet.

	Recommended printing material is PETG for its structural rigidity. However, PLA will likely work fine as well, and is easier to print. A 0.6mm nozzle was used for test prints, but any nozzle should work. Depending on the layer height you choose, your print may come out slightly thicker or thinner; this is no problem though. It's recommended to enable the advanced "Detect Thin Walls" option in slic3r to get a cleaner g-code result around the fan holes.		Recommended printing material is PETG for its structural rigidity.

	The print will take approximately 7.8 metres of filament, and take in the order of one hour, though this depends on slicer settings and printer model.		The print will take approximately 7.8 metres of filament, and take in the order of one hour, though this depends on slicer settings and printer model.

	An unfortunate side effect of perfectly centreing the fan mount is that the SoC of the ROCK64 will be right below the fan's centre, where there is little airflow. However, the spread out nature of the heatsink and the distance between fan and SoC still allow it to cool down effectively. Its cooling performance with a Noctua NF-A4x10 5V PWM is enough to no longer throttle after a few minutes of cpuburn, but comfortably sitting at below 75°C instead. The memory has no temperature sensor, but will likely be ~~getting~~ a ~~much bigger benefit due~~ to ~~being off~~-~~centre~~.
