SilverStone today launched the FHS line of 24 V high performance industrial fans that come with 4-pin PWM connections. The FHS80X 24V is a 38 mm-thick 80 mm fan, while the FHS120 24V is a more standard 25 mm-thick 120 mm fan. Both come with high-RPM motors and impellers tuned to maximize airflow. FHS80X 24V turns at speeds ranging between 0 RPM and an impressive 8,700 RPM, at which speed it pushes 70.3 CFM of airflow at 39.5 mm H₂O of static pressure, but at 55 dBA of noise output.

The FHS120X 24V, on the other hand, turns between 755 RPM and 3,500 RPM, pushing up to 110 CFM of airflow at 7.03 mm H₂O static pressure, at 45.6 dBA of noise output. Both fans come with metal-reinforced hubs, frames made of high-grade PBT, and impellers made of PPE. FHS120X 24V comes with rubberized frame mounts that dampen vibrations, while the FHS80X 24V includes a metal grille given its hazardous speed. Both fans come with industry-standard 4-pin PWM connections, however the power source should be 24 V-capable. It also includes a 4-pin to 2-pin adapter for other applications. The company didn't reveal pricing.
