==Overview==
The X-FAN40 is a PWM fan HAT designed for active cooling of M.2 devices or dual cooling on the Raspberry Pi 5. It integrates seamlessly with the X1001-Max, X1004, and similar NVMe expansion boards while remaining compatible with standard Pi cooling solutions.
Its 40mm PWM fan delivers up to 6.01 CFM - over five times the airflow of the official Pi active cooler - providing reliable thermal management for sustained high-load operations. It is the ideal cooling solution for power-intensive devices like AI accelerator cards and high-performance SSDs.
==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.
