Raspbbery Pi 3 - Enclosure remix with top mount for fan

NOTE: This remix only contains the modified top part, for rest of part see the original enclosure !

Not compatible with Raspberry Pi 4, it has a different port layout!

I had printed the excellent Raspberry Pi enclosure by msonst but struggled with high CPU temperatures. My Pi was sitting around 60°C (140°F) at idle with a heatsink - a bit too much for running it in a 24/7 environment.

So I remixed the original design by extending the top a bit higher and added a place for a 40x40x10mm fan and side exhaust ventilation holes.

The new design with fan and existing heatsink dropped the temperature down from 60°C to 32°C - almost in half!

The design supports heatsinks.

Before the fan arrived tested out with just passively cooled with the extended top and noticed a temp drop to 45°C. So I would even recommend using my design to increase the lifespan of the Raspberry Pi, especially if in a NAS setup it's run 24/7.

Under cpu stress test with the fan and heatsink the Pi reached the max temp of 48.3°C.

I ended up buying a Noctua NF-A4x10 5V fan (non-pwn version) (expensive option, but delivers amazing airflow at a low noise level)
