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 :)
