The SupTronics X-FAN40 is a high-performance PWM fan HAT designed to provide active cooling for Raspberry Pi 5 systems and M.2 NVMe expansion boards such as the X1001-Max and X1004. Its powerful 40mm PWM fan delivers up to 6.01 CFM airflow, offering significantly greater cooling performance than the official Raspberry Pi active cooler. Designed for sustained high-load operation, it helps maintain stable temperatures for demanding applications including AI accelerator cards, high-performance SSDs, and other power-intensive workloads. The stackable top-mount design also allows it to integrate neatly alongside other HATs and expansion boards. Please note: Raspberry Pi 5 not included. Features * Dual-Cooling Versatility: Dedicated cooling for M.2 devices or supplemental cooling for Raspberry Pi 5. * Seamless Compatibility: Designed to fit perfectly with X1001-Max/X1004 NVMe expansion boards. * High-Performance Airflow: 40mm PWM fan delivers 6.01 CFM – over 5x the airflow of the official Pi active cooler. * Sustained Performance: Maintains stable temperatures under continuous high load. * Built for Demanding Workloads: Ideal cooling solution for power-intensive applications, including AI accelerator cards and high-performance SSDs. * Stackable Top-Mount Form: Mounts on top of the M.2 HAT or Pi 5, allowing seamless stacking with other HATs. * XH2.54 Power Output: Equipped with 5V power output connectors for expanded functionality.
