Package Contents
The Aigo AIR12S fan package typically includes:
- Aigo AIR12S 120mm ARGB PWM Fan(s)
- Mounting Screws
- (Depending on the variant, a controller or additional cables may be included)

Installation Guide
1. Safety Precautions
- Ensure your computer is powered off and unplugged from the wall outlet before installation.
- Discharge any static electricity by touching a grounded metal object.
- Handle components carefully to avoid damage.
2. Fan Direction (Forward/Reverse Blade)
The Aigo AIR12S fans offer optional forward and reverse blade designs, allowing flexibility in airflow direction. This is crucial for optimizing cooling within your PC case.
- Forward Blade: Typically used for intake, drawing air into the case.
- Reverse Blade: Typically used for exhaust, pushing air out of the case, while maintaining the aesthetic front-facing appearance.

3. Mounting the Fan
- Identify the desired mounting location (e.g., front, top, rear of the case, or radiator).
- Align the fan with the screw holes.
- Secure the fan using the provided mounting screws. Do not overtighten.

4. Connecting the Cables
The Aigo AIR12S fan uses two main connectors:
- 4-pin PWM Connector: Connect this to a 4-pin fan header on your motherboard or a fan controller. This allows for Pulse Width Modulation (PWM) control, enabling dynamic fan speed adjustment based on CPU temperature.
- 5V 3-pin ARGB Connector: Connect this to a 5V 3-pin Addressable RGB (ARGB) header on your motherboard or an ARGB controller. Ensure it is a 5V 3-pin header; connecting to a 12V 4-pin RGB header will damage the LEDs.

Operating Instructions
1. Fan Speed Control (PWM)
The 4-pin PWM connector allows your motherboard or fan controller to precisely control the fan speed (800-1600 RPM ± 10%) based on system temperature. This ensures efficient cooling and reduced noise when full performance is not required.
- Access your motherboard's BIOS/UEFI settings or use compatible software provided by your motherboard manufacturer to configure fan curves.
- Adjust the fan speed profiles to balance cooling performance and noise levels according to your preference.

2. ARGB Lighting Control
The 5V 3-pin ARGB connector enables customizable lighting effects. The fan features 15 million real-time color changes, an infinite mirror side glow, and extendable light strips with linked effects.
- Use your motherboard's ARGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, Gigabyte RGB Fusion, ASRock Polychrome Sync) to synchronize and customize the lighting.
- Explore various lighting modes, colors, and effects to match your system's aesthetic.
- The fan's surface light strips are designed to be spliced to create linked effects with other compatible ARGB components.

Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your fan.
- Cleaning: Periodically clean the fan blades and frame to remove dust buildup. Use compressed air or a soft, dry cloth. Ensure the fan is powered off and disconnected before cleaning.
- Inspection: Check cables for any signs of wear or damage. Ensure all connections are secure.
- Bearing: The Hydro Bearing is designed for long life (100,000 hours) and generally requires no lubrication.
Troubleshooting
Fan Not Spinning
- Ensure the 4-pin PWM connector is securely plugged into the motherboard or fan controller.
- Check BIOS/UEFI settings to ensure the fan header is enabled and configured correctly.
- Verify that the power supply is functioning correctly.
ARGB Lights Not Working
- Confirm the 5V 3-pin ARGB connector is correctly attached to a compatible 5V 3-pin ARGB header on your motherboard or controller. Do NOT connect to a 12V 4-pin RGB header.
- Check your motherboard's ARGB software for proper configuration and enabled lighting effects.
- Ensure all ARGB cables are securely connected.
Fan is Too Loud
- Adjust the fan speed curve in your motherboard's BIOS/UEFI or software to reduce RPM at lower temperatures.
- Ensure the fan is securely mounted and not vibrating against the case.
- Clean any dust buildup on the fan blades.
User Tips
- When planning your PC build, consider the airflow direction carefully. Using a mix of forward and reverse blade fans can help achieve optimal positive or negative pressure within your case while maintaining a consistent aesthetic.
- For advanced ARGB customization, explore third-party software or dedicated ARGB controllers if your motherboard's software is limited.
- The LED strips on the fan are designed for linked effects; ensure proper connection if you are using multiple fans to create a continuous lighting display.
