AirCowl: DIY PC Fan Neck Cooler Project

The AirCowl is a 3D printable personal cooling system that transforms a standard PC fan into a comfortable, wearable neck cooler. Perfect for hot summer days, outdoor work, or anyone who runs warm, this innovative design provides targeted cooling right where you need it most.

This project combines 3D printing with basic electronics to create a hands-free cooling solution. The ergonomic collar design distributes weight evenly around your neck while directing airflow for maximum comfort. The modular design allows for customization based on your specific PC fan size and personal preferences.

Electronic Bill of Materials

• Fan 60x60x10 mm DC 12V 6010 — any standard 60 mm PC case fan, e.g. GDSTIME GDA6010S12V brushless fan (2-pin, ≈0.15 A)
• IP5328P V1.0 power-bank board — dual USB-A + USB-C, 4-LED fuel gauge (handles cell charging and 5 V output)
• 5 V → 12 V DC-DC boost converter — MT3608 (or similar) rated ≳ 2 A to power the 60 mm fan
• 2 × 18650 Li-ion cells — protected cells recommended
• 4 × M3 × 10 mm screws — for mounting the fan
• Hook-up wire, JST/Dupont leads, heat-shrink tubing — basic wiring & strain relief
