Vỏ Raspberry Pi 3B+ cho quạt Noctua 40x10

Case for Noctua 5V 40x10mm 4 pin Fan...
Snap together assembly, no screws required.

CPU stays very Cool. 36C during stress test (100% Fan)

Screwless!

Frame4Fan-SimpleNoScrews-Assy

Frame with posts, does not require screws for the case and pi, removes need for standoffs. Fan fits into frame without need for screws.

If you want to use screws...

Frame-Fan-4BrassStandoffs.stl

Screws M2.5 8mm long 4x
Standoffs M2.5 10mm long 4x
nuts M2.5mm 4x

CPU takes 9mm tall (9.4mm) Heatsink...

Fan fits into fan frame snugly, no screws required. M2.5 screws needed on bottom of case to secure Pi4B board to standoffs.

Case also fits into
Bracket For Case (Raspberry Pi 3B and 4B) Cases

Case cover snaps on.

Fan connects to GPIO pins and can be controlled via PWM.

More later... after I learn how to implement it ... Any help on this is welcome.

Supports are required and much time and effort was put into finding the correct supports that could be easily removed and develop a clean part...

The gcode file for the top, BigDome.gcode has this support and it can be removed by fitting a flat razor or thin piece of metal and prying up on the sides... the entire support can be removed in a single piece, requiring very little cleanup.

Pufcase.gcode has prefabbed supports which pop out.
