Noctua NA-FH1 computer cooling system part/accessory Fan controller

Noctua NA-FH1 computer cooling system part/accessory Fan controller 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.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.Up to 54W via S-ATA and 24W via 4-pinWhen 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 safelyIf 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 monitoringThe 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.Compatible with 4-pin PWM and 3-pin fansWhile 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.Suitable for 12V and 5V fansSupporting both 12V and 5V (4-pin power input only) operation. the NA-FH1 not only works great with 12V PC fans. but is
