NOCTUA Manual fan speed controller NA-FC1 4-PINES PWM 1356031

The NA-FC1 is a compact and highly flexible controller for 4-pin PWM fans that can be used on its own to manually reduce fan speed or together with the motherboard’s automatic fan control. By adjusting the NA-FC1’s speed dial, users can manually select a PWM duty cycle from 0 to 100% or reduce the PWM duty cycle set by the PC motherboard, allowing the fans to run more slowly than the motherboard’s automatic fan control would otherwise allow. The brightness of the orange LED provides a visual indication of the selected speed, while the button activates the NA-FC1’s “No Stop” mode, preventing the fan from running at speeds below 300 rpm. The included 3-way splitter cable and power supply adapter allow up to 3 fans to be controlled simultaneously. PWM-based control While most fan controllers are voltage-based, the NA-FC1 uses the more sophisticated Pulse Width Modulation (PWM) technique, which enables more efficient control and lower minimum speeds, regardless of the fan’s starting voltage. “Manual Control” mode“Manual Control” mode If the NA-FC1 does not receive a PWM signal from the motherboard, it acts as a simple and efficient manual controller that allows the duty cycle to be set from 0 to 100%. This makes it perfect for manually slowing down high-speed PWM fans, such as Noctua’s industrialPPC series, for quiet operation. Customised motherboard fan controlCustomised motherboard fan control Many motherboards offer insufficient options for customising automatic fan control or simply do not work below certain duty cycles or speed levels. Using the NA-FC1, the motherboard’s PWM control line can be reduced to achieve truly quiet operation, even with high-speed PWM fans such as Noctua’s industrialPPC series. “No Stop” mode“No Stop” mode When the small button is pressed and the green LED lights up, the NA-FC1 operates in “No Stop” mode, which means it will not allow the fan to run below 300 rpm, regardless of the speed setting or the motherboard’s incoming PWM duty cycle, preventing fan errors in the BIOS. 3-way splitter cable3-way splitter cable The included 3-way splitter cable allows up to three 4-pin PWM fans to be connected and controlled simultaneously. Even more fans can be controlled at the same time by using additional NA-YC1 splitter cables, which are included with many Noctua fans and are available as an optional accessory kit (NA-SYC1). Power supply adapterPower supply adapter Connecting several fans with different power ratings to a single motherboard connector can damage the motherboard. The NA-FC1 therefore includes an NA-AC4 adapter that connects the device directly to the power supply unit while simultaneously receiving PWM input from the motherboard and returning RPM information. This makes it ideal for controlling several high-speed fans, such as Noctua’s 3000rpm industrialPPC models. 6-year manufacturer’s warranty6-year manufacturer’s warranty Noctua products are known for their impeccable quality and outstanding longevity. Like all other products, the NA-FC1 fan controller is designed to last and comes with a full 6-year manufacturer’s warranty.
