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.

When powering the NA-FH1 via the 4-pin input from a PC motherboard,

please check your motherboard manual for the maximum current of the

fan header and make sure not to exceed it.

Noctua NA-FH1 | User manual

The NA-FH1 transmits the RPM speed signal of the fan connected to the first port to

the motherboard for speed monitoring. For additional watchdog functionality, all ports

feature status LEDs that light up if an RPM signal is being received and go off if the fan

stops or fails.

Example setups

Caution: Do not place directly on hard disk drives, keep at least 5cm distance.

Application example 1: Powering and controlling low-current PC PWM fans via a motherboard fan header (24W max.)

Application example 2: Controlling high-current PC PWM fans safely via a motherboard fan header using S-ATA power (54W max.)

If both its S-ATA and 4-pin input ports are connected, the NA-FH1 will automatically draw power via S-ATA and use the 4-pin port for PWM control and RPM monitoring only. This way, it is

possible to control fans with high power consumption safely without risking damage to the motherboard.

Caution: Please make sure that your power supply can provide the required current on the 12V rails, especially if they are heavily loaded by a GPU or other appliances.
