4. Setup and Installation
Before beginning installation, ensure your computer is powered off and unplugged from the wall outlet. Exercise caution to avoid static discharge.
4.1. Fan Placement and Mounting
- Identify suitable mounting locations within your PC case (e.g., front, top, rear, bottom). Consider airflow direction for optimal cooling (intake or exhaust).
- Position the fan in the desired location. Use the provided screws to secure the fan to the case. Ensure the anti-vibration rubber pads are correctly aligned.


4.2. Power Connection (PWM)
- Connect the 4-pin PWM cable from the fan to an available 4-pin fan header on your motherboard (e.g., CHA_FAN or CPU_FAN).
- If installing multiple fans, daisy-chain the PWM connectors. The FX120 fans support daisy-chaining for synchronized fan speed control.
- Alternatively, fans can be powered directly via a 4-pin D-type Port from your power supply. Do not connect both 3-pin (motherboard) and 4-pin (power supply D-type Port) simultaneously to avoid short circuits!
4.3. RGB Lighting Connection (ARGB)
- Connect the 3-pin +5V ARGB cable from the fan to an available 3-pin +5V ARGB header on your motherboard.
- For multiple fans, daisy-chain the ARGB connectors to synchronize lighting effects across all fans.
- If your motherboard does not have an ARGB header, use the included wired ARGB LED controller to manage lighting effects.

5. Operating Instructions
5.1. Fan Speed Control (PWM)
The FX120 fans utilize PWM (Pulse Width Modulation) technology, allowing your motherboard to precisely control fan speed based on system temperature. This ensures optimal cooling performance and reduced noise levels when full speed is not required.
- Access your motherboard's BIOS/UEFI settings or use a compatible software utility provided by your motherboard manufacturer to configure fan curves.
- Adjust the fan speed to balance cooling performance and acoustic levels according to your preference.
5.2. RGB Lighting Control
The Addressable RGB (ARGB) lighting of the FX120 fans offers extensive customization.
- Motherboard Sync: If connected to a compatible 3-pin +5V ARGB header, use your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion) to customize colors, effects, and synchronize with other ARGB components.
- Wired Controller: If using the included wired ARGB LED controller, cycle through the pre-set lighting modes, colors, and speeds using the buttons on the controller.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your PCCOOLER FX120 fans.
- Cleaning: Periodically clean dust from the fan blades and frame using compressed air or a soft, dry cloth. Ensure the fan is powered off and disconnected before cleaning.
- Inspection: Check for any obstructions around the fan blades or unusual noises during operation.
- Cable Management: Ensure all cables are neatly routed and secured to prevent interference with moving parts or airflow.
7. Troubleshooting
7.1. Fan Not Spinning
- Check if the 4-pin PWM connector is securely plugged into the motherboard fan header or the 4-pin D-type power port.
- Ensure your power supply is functioning correctly.
- Verify fan speed settings in your motherboard's BIOS/UEFI or software.
7.2. RGB Lighting Not Working
- Confirm the 3-pin +5V ARGB connector is correctly attached to the motherboard ARGB header.
- If using the wired controller, ensure it is properly connected and try cycling through modes.
- Check your motherboard's RGB software for correct settings and ensure ARGB synchronization is enabled.
- Important: Ensure the ARGB connector is not plugged into a 12V RGB header, as this can damage the LEDs.
7.3. Excessive Noise
- Verify that the fan is securely mounted and the anti-vibration pads are in place.
- Check for any cables or obstructions touching the fan blades.
- Adjust fan speed settings in BIOS/UEFI or software to a lower RPM if noise is a concern.
