Simple Raspberry Pi Mount for Noctua NF-A4x10 Fan

thingiverse

This is a simple plate mount designed to hold a Noctua NF-A4x10 fan over a Raspberry Pi. It's intended to be mounted above the Pi using M2.5 standoffs via the Pi's standard mounting holes. The fan mounts with M4 bolts, which easily thread into the plate. (Nuts optional.) Note for anyone wanting an easy solution for a high-quality Pi fan: the NF-A4x10 5V (the NON-PWM version) can easily be adapted to be powered from the Pi's 5v bus by simply cutting the wire from the fan, attaching female pin leads to the red and black wires, and simply cutting and ignoring the yellow wire. (The yellow wire provides no speed control, but rather a tachometer-style speed signal to tell you how fast the fan is spinning. I haven't figured out how to use it yet, but if you want to try, you can always tack on a lead to it, too.) Have fun, and enjoy the silence.
