The Noctua NA-FC1 is a compact 3-channel fan speed controller for 4-pin PWM fans. It can operate as a standalone manual controller or work together with motherboard PWM control to lower the duty cycle supplied by the board. The unit includes a speed control dial with an orange status LED for visual feedback, a push button to enable a “no stop” mode that prevents fan speeds below 300 rpm, a 3-way splitter cable to control up to three fans, and a power supply adaptor (NA-AC4) to power multiple or high-wattage fans directly from the PSU while passing PWM input and RPM information to the controller.

Advantages

The NA-FC1 uses PWM-based control for efficient and precise speed regulation, allowing lower minimum speeds than voltage-based controllers. It supports both manual 0–100% duty cycle adjustment and fine-tuning of motherboard PWM curves to achieve quieter operation with high-speed fans. The built-in “no stop” mode avoids BIOS fan errors by keeping speeds above 300 rpm, and the supplied PSU adaptor prevents overloading motherboard fan headers when multiple or power-hungry fans are connected. Compact dimensions and a black finish make it easy to integrate into various PC builds.

Suitable for

• Controlling up to three 4-pin PWM case or radiator fans simultaneously
• Manually reducing speeds of high-speed PWM fans (e.g., industrialPPC series)
• Lowering motherboard PWM curves to achieve quieter operation
• Powering multiple high-wattage fans safely using the included PSU adaptor

Key specifications

• Channels: 3 (via supplied 3-way splitter)
• Connector type: 4-pin PWM input/output
• Input voltage: 5–12 V
• Maximum output current: 3000 mA
• Minimum enforced speed in “no stop” mode: 300 rpm
• Dimensions (W × D × H): 48 × 21 × 25 mm
• Colour: Black
• Manufacturer’s warranty: 6 years

How to use

Connect the NA-FC1’s PWM input to a motherboard fan header and attach up to three 4-pin PWM fans to the supplied 3-way splitter. If multiple or high-current fans are used, connect the NA-AC4 power adaptor to the PSU and the NA-FC1 so the fans draw power from the PSU while PWM and RPM signals are still passed to the motherboard. Rotate the speed control dial to set the desired PWM duty cycle (0–100%). Press the push button to toggle “no stop” mode; when enabled, the green LED lights and the controller prevents fan speeds dropping below 300 rpm.

Recommendations

Use the NA-FC1 to fine-tune noisy high-speed PWM fans or to lower a motherboard’s automatic fan curve; when connecting several high-wattage fans, always use the supplied PSU adaptor to avoid stressing the motherboard header.
