- 1 x PC Fan Hub / ARGB Controller
- 1 x ARGB Controller Remote
- 1 x 5V 3-Pin ARGB Cable
- 1 x PWM Cable
- 1 x Power Cable (SATA)
- 12 x Mounting Screws
3. Features
- 3-Pin ARGB & 4-Pin PWM 120mm Fan: Compatible with most motherboards or the included ARGB controller, operating at 1600 ±10% RPM with 48.32 CFM airflow and 1.75 mmH₂O pressure for quiet 27.36dBA, efficient cooling.
- Unified ARGB Controller Hub: Manages lighting effects and fan speeds for multiple RGB fans from a single unit, reducing cable clutter.
- Convenient Remote Control: Adjust RGB fan lighting modes, brightness, and fan speeds without opening your PC or using software.
- RGB Motherboard Sync: Hold the MODE button for 3 seconds to sync the RGB fans with your motherboard software at startup. Sync automatically resumes upon system restart.
- Daisy-Chainable Design: Fans feature male and female ARGB and PWM connectors for easy daisy-chaining, minimizing cable usage when connecting directly to the motherboard.
4. Setup and Installation
Follow these steps to install your darkFlash DM12PRO fans and controller hub.
- Fan Placement: Determine the optimal placement for your fans within your PC case for desired airflow (intake or exhaust). Use the included mounting screws to secure each fan.
- Connecting Fans to Controller Hub: Connect the 4-pin PWM cable from each fan to the 'FAN' ports on the controller hub. Connect the 3-pin ARGB cable from each fan to the 'ARGB' ports on the controller hub. The fans are designed to be daisy-chained, allowing multiple fans to connect to a single port on the hub if needed.
- Controller Hub Power: Connect the included SATA power cable to the controller hub and to an available SATA power connector from your power supply unit (PSU).
- Motherboard Connections (Optional):
- PWM Sync: Connect the PWM cable from the controller hub to an available 4-pin PWM fan header on your motherboard (e.g., CPU_FAN or SYS_FAN). This allows your motherboard to control fan speeds based on system temperature.
- ARGB Sync: Connect the 5V 3-Pin ARGB cable from the controller hub to a compatible 5V 3-Pin Addressable RGB header on your motherboard (e.g., AURA Sync, Mystic Light Sync, RGB Fusion, Polychrome RGB). This enables software control of lighting effects.
- Remote Control: The remote control is pre-paired with the controller hub. Ensure the plastic tab is removed from the battery compartment before first use.

5. Operating Instructions
Once installed, operate your darkFlash DM12PRO fans using the remote control or motherboard software.
5.1. Remote Control Operation
The included remote control allows for direct management of fan lighting and speed.
- ON/OFF: Power the fans and lighting on or off.
- AUTO: Cycles through various pre-programmed ARGB lighting effects.
- S+/S-: Adjust the speed of the lighting effects.
- M+/M-: Change between different lighting modes.
- Color Buttons: Select a static color for the fan lighting.
- Brightness Buttons: Adjust the brightness of the ARGB lighting.
- M/B Button: Hold for 3 seconds to switch between remote control mode and motherboard synchronization mode.
5.2. Motherboard Synchronization
If connected to a compatible 5V 3-Pin ARGB header on your motherboard, you can control the fan lighting via your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome RGB).
- Ensure the M/B button on the remote is held for 3 seconds to activate motherboard sync mode.
- Once enabled, the lighting will be controlled by your motherboard software and will automatically resume sync upon system restart.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your fans.
- Cleaning: Periodically clean the fan blades and frames to remove dust buildup. Use compressed air or a soft, dry cloth. Ensure the PC is powered off and unplugged before cleaning.
- Cable Management: Ensure all cables are neatly routed and secured to prevent interference with fan blades or other components.
7. Troubleshooting
If you encounter issues, refer to the following common solutions:
- Fans Not Spinning:
- Check if the SATA power cable is securely connected to the controller hub and the PSU.
- Verify that the 4-pin PWM cables from the fans are correctly plugged into the controller hub.
- If using motherboard PWM control, ensure the PWM cable from the hub is connected to a functional motherboard fan header.
- RGB Lighting Not Working:
- Ensure the 3-pin ARGB cables from the fans are properly connected to the controller hub.
- If using the remote, check the battery and ensure the remote is pointed towards the hub's receiver.
- If using motherboard sync, ensure the 5V 3-Pin ARGB cable from the hub is connected to a compatible motherboard header and that the M/B button on the remote has been pressed for 3 seconds to switch to motherboard control. Check your motherboard's RGB software settings.
- Inconsistent Fan Speed:
- If using motherboard PWM control, check your BIOS/UEFI settings or motherboard software for fan curve adjustments.
- Ensure the PWM cable from the hub is connected to a PWM-enabled header, not a DC-only header.
