5. Setup and Installation
Before beginning installation, ensure your computer is powered off and unplugged from the wall outlet. It is recommended to wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage to components.
5.1. Pre-Installation Check
- Verify that your PC case has available 120mm fan mounts.
- Ensure your motherboard has a 4-pin PWM fan header and a 3-pin 5V ARGB header (sometimes labeled as "D_LED" or "ADD_HEADER").
5.2. Physical Installation
- Open your PC case.
- Identify the desired fan mounting location (e.g., front, top, rear, bottom).
- Position the FOIFKIN fan against the mounting holes, ensuring the airflow direction is correct for your system's cooling strategy (this fan is designed for forward airflow, typically intake).
- Secure the fan to the case using the provided mounting screws. Do not overtighten.

5.3. Electrical Connections
- Connect the 4-Pin PWM Cable: Locate an available 4-pin fan header on your motherboard (often labeled "CPU_FAN", "SYS_FAN", or "CHA_FAN"). Connect the fan's 4-pin cable to this header.
- Connect the 3-Pin ARGB Cable: Locate an available 3-pin 5V ARGB header on your motherboard. Connect the fan's 3-pin ARGB cable to this header. Warning: Do not connect to a 4-pin 12V RGB header, as this will damage the fan's LEDs.
- If installing multiple ARGB fans, you may need an ARGB hub or splitter (not included) if your motherboard has insufficient headers.
6. Operating Instructions
6.1. Fan Speed Control (PWM)
The fan's speed is controlled via the 4-pin PWM connection. Most modern motherboards allow you to configure fan curves in the BIOS/UEFI settings or through dedicated motherboard software (e.g., ASUS AI Suite, MSI Dragon Center, Gigabyte SIV, ASRock A-Tuning). You can set the fan to automatically adjust its speed based on CPU or system temperature, or manually set a fixed speed.
6.2. ARGB Lighting Control
The Addressable RGB lighting can be controlled through your motherboard's ARGB software. Examples include:
- ASUS Aura Sync
- MSI Mystic Light Sync
- Gigabyte RGB Fusion
- ASRock Polychrome Sync
Install the appropriate software for your motherboard to customize lighting effects, colors, and synchronization with other ARGB components.

7. Maintenance
Regular maintenance helps ensure optimal performance and extends the lifespan of your fan.
- Dust Removal: Periodically clean dust from the fan blades and frame using compressed air or a soft brush. Ensure the fan is powered off before cleaning.
- Inspection: Check for any obstructions or loose cables around the fan.
- Avoid Liquids: Do not use liquid cleaners directly on the fan or its electrical components.
