Noctua NA-FH1 8 Channel PWM Fan Hub NA-FH1

[features] Up to 54W via S-ATA and 24W via 4-pin When powered via it’s S-ATA interface (for 12V fans only); the NA-FH1 can run fans with a combined power draw of up to 54W. When using the 4-pin PWM input only (for 5V or 12V fans); the maximum power draw can go as high as 24W. Controlling high-power fans safely 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.
RPM and status monitoring 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 white status LEDs that light up if an RPM signal is being received and go off if the fan stops or fails. Compatible with 4-pin PWM and 3-pin fans While only 4-pin PWM fans can be controlled via PWM; the NA-FH1’s keyed output connectors are also compatible with 3-pin fans; so it can also be used to run multiple 3-pin fans from a single power source and to adjust their speed simultaneously by reducing the input voltage.
Ideal combination with optional NA-FC1 fan controller The NA-FH1 is ideal for controlling multiple PWM fans using the optional NA-FC1 controller. Thanks to a reverse-power design on the 4-pin input of the NA-FH1; the NA-FC1 can control the connected fans even if the hub is powered via its S-ATA interface only and if there is no other connection or input on the 4-pin interface. Safety certifications Unlike many cheap fan hubs; the NA-FH1 has been carefully tested for product safety and EMC compliance. Carrying CE; UKCA and UL certifications and meeting all applicable standards (EN 62368-1; EN 55035; EN 55032; UL-507); it is a safe; quality device through and through.
6-year manufacturer’s warranty Noctua products are renowned for their impeccable quality and outstanding longevity. Like Noctua’s fans and heatsinks; the NA-FH1 is a robust; dependable product that has been carefully engineered to stand the test of time. CAUTION: Do not place directly on hard disk drives; keep at least 5cm distance. When powering 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.
