3. Safety Information
Always observe the following safety precautions to prevent injury and damage to your equipment:
- Ensure your computer system is powered off and unplugged from the wall outlet before installation or maintenance.
- Handle components with care to avoid static discharge. Consider using an anti-static wrist strap.
- Do not force connectors. Ensure proper orientation before plugging in cables.
- Keep fans and cables away from moving parts inside the computer case.
- Do not attempt to disassemble or modify the fans or controller.
- This product is designed for use in computer systems. Do not use for other purposes.
4. Setup and Installation
Follow these steps to install your Vetroo SA-140 cooling fans:
- Prepare Your System: Power off your computer and unplug it from the power outlet. Open your PC case.
- Mount the Fans:
Identify the desired fan mounting locations in your PC case (e.g., front, top, rear). Use the included mounting screws to secure each fan. Ensure the fan's airflow direction (indicated by arrows on the fan frame) is correct for your cooling setup (intake or exhaust).

- Install the Controller Hub:
Find a suitable location inside your PC case for the fan controller hub. It can be mounted using double-sided tape (not included) or placed in an accessible area. Ensure it's not obstructing airflow or other components.

- Connect the Fans to the Controller:
Each fan has two cables: a 4-pin PWM cable and a 3-pin ARGB cable. Connect the 4-pin PWM cables from the fans to the "FAN-A" or "FAN-B" ports on the controller hub. Connect the 3-pin ARGB cables from the fans to the corresponding "ARGB-A" or "ARGB-B" ports on the controller hub.

- Connect Controller to Power Supply:
Connect the two SATA power cables from the controller hub to available SATA power connectors from your PC's power supply unit (PSU).
- Connect Controller to Motherboard (Optional for Motherboard Sync):
If you wish to synchronize the RGB lighting and fan speed with your motherboard, connect the following cables from the controller hub to your motherboard:
- Connect the 4-pin PWM cable (labeled "PC IN PWM/FG" or similar) from the controller to a 4-pin CPU_FAN or SYS_FAN header on your motherboard. This allows the motherboard to control fan speed.
- Connect the 3-pin ARGB cable (labeled "PC IN ARGB" or similar) from the controller to a 5V 3-pin Addressable RGB header on your motherboard. Do NOT connect to a 12V 4-pin RGB header, as this will damage the LEDs.
- Close Case and Power On: Once all connections are secure, close your PC case, plug in the power cable, and power on your system.
5. Operating Instructions
5.1. RGB Lighting Control
You can control the RGB lighting via the included remote control or through your motherboard's software (if connected to the motherboard ARGB header).
Using the Remote Control:
The remote control allows for various lighting modes, colors, and effects. Point the remote towards the controller hub for best results.

Image: Layout of the remote control with descriptions of each button's function, including power, speed, mode, luminosity, color shortcuts, and music modes.
- ON/OFF Lights: Power button to turn RGB lights on or off.
- SPEED +/-: Adjusts the speed of dynamic lighting effects.
- MODE +/-: Cycles through different lighting modes and effects.
- AUTO: Automatically cycles through all available modes.
- Luminosity Adjustment: Increases or decreases the brightness of the LEDs.
- Monochromatic Shortcut Keys (R, G, B, W): Directly select Red, Green, Blue, or White static colors.
- M/B (Motherboard/Controller Signal Switching):
- When the controller is first connected to the 5V ARGB port of the motherboard, the light effect automatically switches to motherboard control.
- Press the ON/OFF button on the remote for about 2 seconds; the fan LED will flash white once, and control will switch back to the motherboard.
- Music Mode 1, 2, 3: Activates lighting effects synchronized with audio (requires compatible setup, not all motherboards support this via controller).
Motherboard Software Control:
If you connected the 3-pin ARGB cable to your motherboard, you can use your motherboard's proprietary RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome Sync) to control the fan lighting. Refer to your motherboard's manual for specific instructions on using its RGB software.
5.2. Fan Speed Control (PWM)
The fans support PWM (Pulse Width Modulation) for precise speed control.

- Motherboard Control: If the controller's PWM cable is connected to your motherboard, the fan speed will be automatically adjusted by your motherboard based on CPU or system temperatures. You can configure fan curves in your motherboard's BIOS/UEFI settings or through its fan control software.
- Controller Control: If not connected to the motherboard's PWM header, the controller may operate the fans at a default speed or allow limited speed adjustment via the remote (if applicable, refer to remote diagram).
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your cooling fans:
- Cleaning: Periodically clean dust from the fan blades and frames using compressed air or a soft, dry cloth. Ensure the system is powered off and unplugged before cleaning.
- Inspection: Check cables for any signs of wear or damage. Ensure all connections remain secure.
- Vibration Pads: Verify that the anti-vibration rubber pads on the fan corners are intact and properly seated to minimize noise.
