The NA-FH1 is a high-quality, efficiently protected 8-channel PWM fan hub that enables the operation and control of up to eight PWM fans simultaneously via a PWM motherboard connection or standalone controllers like the optional NA-FC1. Fans without PWM can be regulated by adjusting the input voltage. The NA-FH1 supports both 12V and 5V fans with 4-pin PWM and 3-pin connectors, making it extremely flexible and suitable for both PC environments and other 12V or 5V-based applications. Power can be supplied either through the S-ATA input (for 12V fans, up to 54W) or the 4-pin PWM input (for 5V and 12V fans, up to 24W). Both connections are protected by a self-resetting fuse against overcurrent, ensuring maximum safety even in the event of short circuits in connected devices or cables. The two ports can be used simultaneously, with power automatically supplied via S-ATA and RPM and PWM signals exchanged through the 4-pin interface. White status LEDs allow for easy monitoring, and thanks to the magnetic mount, installing the NA-FH1 in a PC case or on any other steel surface is a breeze. Completed with CE, UKCA, and UL certifications, full compliance with all applicable safety standards, and a 6-year manufacturer's warranty, the NA-FH1 is a safe, reliable premium solution for powering and controlling up to eight fans.
