Noctua NA-FH1 User Manual

Noctua NA-FH1 | User manual
The NA-FH1 is a high-quality, smartly-protected 8 channel PWM fan hub that allows up to eight PWM fans to be run and controlled simultaneously via a single PWM motherboard fan
header or stand-alone controllers such as the optional NA-FC1. Non-PWM fans can be controlled by adjusting the input voltage. Supporting both 12V and 5V fans with 4-pin PWM and 3-pin
connectors, the NA-FH1 is highly flexible and suitable both for PC environments and other 12V- or 5V-based applications. It can be powered either via its S-ATA input (for 12V fans, up to
54W) or 4-pin PWM input (for 5V and 12V fans, up to 24W), both of which are protected against overcurrent with a self-resetting fuse for maximum safety even in case of short-circuits
on the connected devices or cables. The two ports can also be used concurrently with the device, automatically taking power via S-ATA and exchanging RPM and PWM signals via the 4-pin
interface. Status LEDs allow for easy monitoring and thanks to its magnetic fixture, installing the NA-FH1 inside a PC case or on any other steel surface is a breeze. Topped off with CE,
UKCA and UL certifications, full compliance with all applicable safety standards as well as Noctua’s 6-year manufacturer’s warranty, the NA-FH1 is a safe, dependable premium choice for
powering and controlling up to eight fans.

Resettable fuses
Especially when drawing power from a PC power supply via S-ATA connectors, short-circuits on the connected cables or devices can cause hazardous situations such as cable fires. For extra
safety, the NA-FH1 has auto-resetting fuses both on the S-ATA and on the 4-pin input so that it can automatically shut down in case of overcurrent or short-circuits on one of the connected
devices or cables. If one of the fuses has blown, simply disconnect the NA-FH1 from all power sources for 1 minute to reset it. Make sure that current ratings and maximum operating
temperature are within the specified limits before reconnecting.
