Noctua NV-FH2, 8-kanavainen tuuletinhubi 5V/12V/25V -tuulettimille, musta

Noctua NV-FH2, 8-kanavainen tuuletinhubi 5V/12V/25V -tuulettimille, musta

The nv-fh2 is a flexible, premium-quality 8 channel pwm fan hub that is ideal for powering up to eight fans in home, office or multi-purpose ventilation applications using an external power supply with 5.5mm barrel connector such as noctua’s optional nv-ps1. It’s compatible with 5, 12, and 24v fans with 4-pin pwm and 3-pin connectors and supports up to 60w total power draw. While 3-pin fans can be speed-controlled by voltage adjustment, 5 and 12v pwm fans can be controlled by connecting the optional na-fc1 controller to the nv-fh2’s 4-pin pwm input. Alternatively, the nv-fh2 can also be powered via this input (up to 22w total power draw), e.g. In pc environments where it can be run off motherboard fan headers with pwm control and rpm monitoring, or when used with noctua 5v pwm fan models that include usb power adaptor cables that make it possible to run the nv-fh2 off power banks or standard usb power supplies. Thanks to its advanced protection and signal filtering features, the nv-fh2 not only runs safely with fans that produce high starting currents or transients, but also supports cascading multiple units for controlling up to 71 fans simultaneously. Fixing the nv-fh2 is a breeze thanks to the integrated magnets that enable snap-on placement on steel surfaces, as well as the mounting tabs with screw holes that make it possible to fix it using screws or cable ties. The hub can either be run without the included clip-on cover for easy status monitoring via its white status leds or with the cover on for extra protection from dust, contact or mechanical impact. 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 nv-fh2 represents the gold standard in highly robust multi-purpose splitter boards that work just as nicely inside a pc as in other ventilation applications.5v, 12v and 24v fan supportthanks to its high quality mosfet transistors, the nv-fh2 supports 5v, 12v and 24v fans. This makes it a great choice not only for use with 12v pc case fans, but also for 5v-based home ventilation setups as well as 24v environments such as 3d printers or industrial applications.compatible with 4-pin pwm and 3-pin fanswhile only 4-pin pwm fans can be controlled via pwm, the nv-fh2’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.flexible power inputthe nv-fh2 can be powered either via it’s 5.5mm (outer diameter) / 2.1mm (inner diameter) barrel connector input using a power supply such as the optional nv-ps1 or via the 4-pin pwm input. If both inputs are connected, the nv-fh2 will automatically take power from the barrel connector and only use the 4-pin port for pwm control and rpm monitoring.up to 60w total power drawwhen powered via the barrel connector, the nv-fh2 can run fans with a combined power draw of up to 60w. When using the 4-pin pwm input only, the maximum power draw is limited to 22w using an auto-resetting safety fuse to protect the connector. Each output port is protected by a self-resetting 0.75a fuse.cascading support for up to 71 fansthe nv-fh2 supports cascading in the sense that up to ten nv-fh2 units can be daisy-chained in order to run and control up to 71 fans. The nv-fh2’s control circuit with single bus buffer keeps pwm signals stable without jeopardising ttl logic levels on the follower boards.controlling high-power fans safelyif both its 5.5mm barrel and 4-pin input ports are connected, the nv-fh2 will draw power via the barrel connector and use the 4-pin port only for pwm control and rpm monitoring. This way, it is possible to control fans with high power consumption safely without risking damage to the host device connected to the 4-pin port.safety fusesthe nv-fh2’s 4-pin input is protected with a 1.85a safety fuse so that the connectors specified current limit cannot be exceeded. Additionally, each fan connector is fused separately with 0.75a to prevent overcurrent on the individual outputs.inrush current protectionthe nv-fh2 features a sophisticated inrush current protection that prevents the connected fans from being damaged if a fan with high inrush current is connected or if there are transients from the power input.leds for status monitoringall fan ports of the nv-fh2 feature white status leds that light up if an rpm signal is being received and go off if the fan stops or fails. For more sophisticated watchdog functionality, the rpm signal of the fan connected to output port 1 is transmitted via the 4-pin input port and can be processed by pc motherboards or other devices such as single board computer systems (e.g. Arduino, raspberry pi, etc.).status leds with flank controlthanks to advanced flank control measures, the nv-fh2’s status leds don’t flicker and always show the correct on/off state when a fan is blocked or stopped

Noctua NA-FH1 -tuuletinhubi, musta

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 also an elegant solution for running multiple noctua 5v fans, many of which include usb adaptor cables that can be used to connect the na-fh1 to mobile phone power supplies or power banks.ideal combination with optional na-fc1 fan controllerthe 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.easy installation with magnetsthe na-fh1 features four strong neodymium magnets on the rear side, which allows it to simply snap into place on any magnetic surface such as inside steel pc cases. On non-magnetic surfaces such as aluminum pc cases, the flat rear side of the device makes it possible to easily fix it with double-sided tape or velcro tape.30cm input cable includedthe na-fh1 is shipped with a 30cm na-ec1 input cable to connect it to motherboard pwm fan headers. For applications that require further extending the input cable or extending the output cables to the fans, noctua offers the na-sec1 (30cm) and na-sec3 (60cm) cable sets.overcurrent and short-circuit protection with safety fusesespecially 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.safety certificationsunlike many cheap fan hubs, the na-fh1 has been carefully tested for product safety and emc compliance.

Noctua NA-FC1 PWM-tuuletinsäädin

Noctua NA-FC1 PWM-tuuletinsäädin

The na-fc1 is a compact, highly flexible controller for 4-pin pwm fans that can both work on its own for manual speed reduction and also work in tandem with the automatic motherboard fan control. By adjusting the na-fc1’s speed control dial, users can either manually set a pwm duty cycle from 0 to 100% or reduce the pwm duty cycle supplied by pc motherboards in order to have the fans running slower than the automatic motherboard fan control would allow. While the brightness of the orange status led provides visual feedback on the current dial setting, the push button allows the na-fc1 to be switched into “no stop” mode, which prevents the fan from falling below a speed of 300rpm. Thanks to the supplied 3-way split cable and power supply adaptor, up to 3 fans can be controlled simultaneously.pwm based controlwhile most fan controllers are voltage based, the na-fc1 uses the more sophisticated pulse width modulation (pwm) technique that allows for more efficient control and lower minimum speeds, regardless of the fan’s starting voltage.manual control modeif the na-fc1 doesn’t receive an input pwm signal from the motherboard, it works as a simple and efficient manual controller that allows the duty cycle to be set from 0 to 100%. This makes it ideal for manually slowing down high-speed pwm fans such as noctua’s industrialppc series in order to achieve consistently quiet operation.customising motherboard fan controlmany motherboards provide insufficient options to customise automatic fan control or simply don’t go below certain duty cycles and speed levels. Using the na-fc1, you can lower the motherboard’s pwm control curve in order to achieve truly silent operation, even with high-speed pwm fans such as noctua’s industrialppc series.“no stop” mode“if the small push button is pressed and the green status led is on, the na-fc1 operates in “no stop” mode, which means that it will not allow the fan to fall below 300rpm, regardless of the speed setting and the input pwm duty cycle from the motherboard, thus avoiding bios fan errors.3-way splitter cablethe supplied 3-way splitter cable allows the connection of up to three 4-pin pwm fans in order to control them simultaneously. Even more fans can be controlled at once when using additional na-yc1 splitter cables that are supplied with many noctua fans and available as an optional accessory kit (na-syc1).power supply adaptoras powering multiple higher wattage fans from a single motherboard fan header may damage the motherboard, the na-fc1 includes an na-ac4 adaptor that powers the device directly from the power supply unit while simultaneously receiving pwm input from the motherboard and forwarding rpm information. This makes it ideal for controlling multiple high-speed fans such as noctua’s 3000rpm industrialppc models.6-year manufacturer’s warrantynoctua products are renowned for their impeccable quality and outstanding longevity. Like all of them, the na-fc1 fan controller is built to last and comes with a full 6-year manufacturer's warranty.
