The compact sibling of Chimney Pi — a fully ventilated, actively cooled enclosure for your SBC. Four ventilated panels and a top mesh grille provide all-around airflow, driven by a 40mm PWM fan at the base. The snap-fit panel design makes assembly straightforward and tool-light.
The white frame and gray panel color scheme gives it a clean, mini-PC aesthetic that looks at home on any desk.
Compatible with:
- Raspberry Pi 5 (tested with NVMe hat and Active Cooler — snug fit)
- Radxa X4
Note: Raspberry Pi 5 GPIO header extension does not fit.
What's included:
- STEP files for all printed parts (8 parts for Pi 5, 9 for Radxa X4)
- Full assembly guide with exploded views, print settings, and step-by-step photo instructions
- PWM fan control code and wiring guide for Ubuntu and Raspberry Pi OS (via GitHub)
Hardware required:
- Noctua NF-A4x10 5V PWM (40mm base fan)
- Radxa X4 build additionally requires a second NF-A4x10 and a 40×40×11mm heat sink
- M2.5 heat inserts and screws
The 40mm fan is optional for Pi 5 builds with an Active Cooler installed.
