SlipCase for Raspberry Pi 4b and Noctua 40x10mm

SlipCase-FanCase  is a snap-together Pi4B Case and stand for the 40mm Noctua Fan

IOPlane snaps over IO, used as slide/guide for Pi4B and Fan Assy to slide into Base, carefully snap on cap.

Noctua 40mm fan fits into Fan frame

Fan support with 10mm CPU to Fanblade (8.5mm to frame other chips)

I place heatsinks on chips and run fan in the following configuration…

Wiring:  Warning!

Follow these instructions at your own risk… not an EE… not tested fully (Ubuntu Server only)

I wire the Noctua 5V, 4 wire PWM 40x40x10 fan directly to (Pins 4, 6, 12, and 18).
