Compact 40 mm Cooling

The SXDOOL FFB0412SHN is a 40 mm case fan built for tight spaces in industrial computers, servers and small-form-factor PCs. Its double ball bearing and PBT glass-fibre frame suit continuous duty in embedded or DIY builds that need reliable airflow.

12 V Four-Pin Integration

The fan runs on 12 V DC through a standard 4-pin connector, drawing 0.5 A in operation with a 6 W rating. PWM control lets the host system adjust speed without extra wiring, while the 40×40×28 mm footprint fits existing 40 mm mounts in switch, CPU or GPU coolers.

Sustained High-Speed Operation

At 13 000 RPM the unit moves 43 CFM at 1.075 inH₂O static pressure with a noise level of 54.5 dBA. Rated for 80 000 hours of continuous use across a -10 °C to 70 °C range, it maintains performance in prolonged server or industrial workloads.
