This is a remix of the great Raspberry Pi Case Top of Malolo. We've had a good cooperation over the last few days and have worked on the design and new ideas to make the case even better. So the idea to integrate a fan without the ugly screws. I have therefore built a mount where the fan is simply pushed in. --- **Updates:** 03.01.2020 * added low version for Ice Tower cooler (not yet tested - feedback on the fit would be great) 22.12.2019 * added new low version for 30/40mm fans * added new medium version for 30/40mm fans * added new low PoE Hat version for 40/50mm fans * added new high PoE Hat version for 40/50mm fans * now with better centered push-in mount --- **Please note:** If the size is too big, scale from 100% to 10%. **Low Case** Unfortunately, the GPIO socket connector are a bit too high for the low case and therefore have to be modified. Pull the GPIO pin out of the connector and connect the cables directly to the pins. **Medium Case** You shouldn't have any problems with the fan gpio pins. **PoE Hat** Remove the mounted Sunon fan from the original Raspberry PoE Hat and simply use a bigger 30/40/50mm fan. For Example Pi-FAN, Noctua NF-A4x10 etc. **Replace PoE Hat fan on the original socket** You can use a less noisy replacement fan on the original Hat socket and control it via overlay. The only thing you need is a *JST ZH 1.5* cable which you solder or crimp to the fan. Pay attention to polarity. If the JST-socket is shorted, it will no longer work! If you want to run the fan from system start you have to change the temperature thresholds & cooling-levels settings in the overlay file. **Edit Overlay** cd /boot/overlays sudo cp rpi-poe.dtbo rpi-poe.dtbo.backup sudo rm rpi-poe.dtbo sudo wget https://raw.githubusercontent.com/raspberrypi/linux/rpi-4.14.y/arch/arm/boot/dts/overlays/rpi-poe-overlay.dts sudo nano rpi-poe-overlay.dts I changed values as followed: ``` trip0: trip0 { temperature = <30000>; hysteresis = <5000>; type = "active"; }; trip1: trip1 { temperature = <55000>; hysteresis = <5000>; type = "active"; }; cooling-maps { map0 { trip = <&trip0>; cooling-device = <&fan0 2 2>; }; map1 { trip = <&trip1>; cooling-device = <&fan0 2 2>; }; }; ``` sudo dtc -@ -I dts -O dtb -o rpi-poe.dtbo rpi-poe-overlay.dts (converts .dts to .dtbo) sudo reboot DONE! --- Let me know what I can improve or what wish you have. Looking forward to your makes :)
