This is a custom cooling solution for the Bosgame E3 MiniPC that allows cooling the RAM and SSD. This uses a regular 120mm PC fan.
If you have a 3 or 4 pin PC fan, I recommend getting a power adapter to allow the fan to be powered by USB (For example this). This way you can plug the fan directly in one of the USB port of the MiniPC.

Installation

1. Remove the supports from the printed part. Go slow and don't use too much force to prevent breaking the part.
2. Remove the lower cover by removing the four screws at each corners
3. Align the printed part with the screw holes and use the opening with longer M2 screws (I recommend M2x12) to screw the printed part to the Bosgame case.
4. Slide the 120mm fan in the printed part. This is a rather tight fit so go slow to not break the feet
5. (Optional) Use some M3 screws to secure the fan to the printer part.

Using this with a Fractal fan, I was able to drop my NVME SSD temps by around 15c.
This might work with other Bosgame MiniPC but YMMV.
