3. Setup and Installation
Follow these steps to properly install your AeroCool Phantom M-3 Reverse ARGB Fan into your PC case.
3.1 Safety Precautions
- Always disconnect power from your PC before installing or removing any components.
- Handle components with care to avoid damage from static electricity. Consider using an anti-static wrist strap.
- Refer to your PC case and motherboard manuals for specific fan mounting locations and header types.
3.2 Installation Steps
- Identify Mounting Location: Choose an appropriate 120mm fan mounting location in your PC case (e.g., front, top, rear, bottom). Consider the desired airflow direction (intake or exhaust). The Phantom M-3 Reverse is designed for intake with its reverse blade.
- Position the Fan: Place the fan in the chosen mounting location. Ensure the side with the infinity mirror effect is facing the desired direction for visibility. For intake, the side with the fan blades visible (and usually a sticker indicating airflow) should face outwards.
- Secure the Fan: Use the provided mounting screws to secure the fan to the PC case. Tighten screws evenly but do not overtighten. The fan features eight shock-absorbing pads on the corners to reduce vibration.
- Connect PWM Cable: Locate a 4-pin PWM fan header on your motherboard. Connect the fan's 4-pin PWM cable to this header. This allows the motherboard to control the fan speed based on system temperature.
- Connect ARGB Cable: Locate a 5V 3-pin Addressable RGB (ARGB) header on your motherboard. Connect the fan's 5V 3-pin ARGB cable to this header. Ensure the arrow on the connector aligns with the +5V pin on the motherboard header to prevent damage. Do NOT connect to a 12V 4-pin RGB header.
- Cable Management: Route the fan cables neatly to avoid interference with other components and to improve airflow within the case.
- Power On: Once all connections are secure, close your PC case and reconnect power. Power on your computer to test the fan and ARGB lighting.

4. Operation and ARGB Control
The AeroCool Phantom M-3 Reverse fan operates automatically via its PWM connection and offers extensive lighting customization through its ARGB connection.
4.1 Fan Speed Control (PWM)
The fan's speed (RPM) is controlled by the motherboard's PWM signal. You can typically adjust fan curves and profiles through your motherboard's BIOS/UEFI settings or through dedicated software provided by your motherboard manufacturer (e.g., ASUS AI Suite, MSI Dragon Center, Gigabyte SIV). This allows the fan speed to dynamically adjust based on CPU or system temperatures, optimizing for cooling performance or quiet operation.
4.2 ARGB Lighting Control
The Addressable RGB lighting of the Phantom M-3 Reverse fan is controlled via your motherboard's ARGB software. This allows for synchronization with other ARGB components in your system and access to 16.8 million colors and various lighting effects.
- ASUS Aura Sync: For ASUS motherboards, use the Aura Sync software to customize lighting.
- MSI Mystic Light Sync: For MSI motherboards, use the Mystic Light software.
- Gigabyte RGB Fusion: For Gigabyte motherboards, use the RGB Fusion software.
- Other Motherboards: Consult your motherboard's documentation for compatible ARGB control software.
Through these applications, you can select static colors, dynamic effects (e.g., breathing, strobing, rainbow), and synchronize the fan's lighting with other compatible devices.

5. Maintenance
Regular maintenance helps ensure optimal performance and longevity of your fan.
5.1 Cleaning
- Frequency: Clean your fan every 3-6 months, or more frequently if your environment is dusty.
- Power Off: Always power off and unplug your computer before cleaning.
- Dust Removal: Use compressed air to blow dust off the fan blades and frame. Hold the fan blades gently to prevent them from spinning rapidly, which can damage the bearing.
- Wipe Down: For stubborn dust, gently wipe the blades and frame with a soft, dry, lint-free cloth. Do not use liquid cleaners directly on the fan or its electrical components.
5.2 General Care
- Ensure cables are not obstructing fan blades.
- Avoid placing objects near the fan that could impede airflow.
