2. Safety Information
Please read and understand all safety instructions before installing or operating the fans. Failure to do so may result in damage to the product or other components.
- Always disconnect power from your computer before installation or maintenance.
- Refer to the quick install guide provided with the product.
- For RGB cable synchronization, connect the standard 3-pin-4-position ARGB connector to your motherboard's 3-pin-4-position ARGB port.
- If using a Gigabyte VDG adaptor cable, ensure correct connection to the VDG 3-pin ARGB port.
- Critical Warning: Do not connect a 5V 3-pin ARGB connector to a 12V 4-pin motherboard header. This will cause damage.
- When syncing with an ARGB mini controller, connect the standard 3-pin-4-position ARGB female connector to the controller's ARGB port, then connect the controller's Molex female power connector to the PSU's Molex port.
- Ensure all connections are secure to prevent electrical shorts or disconnections.
3. Setup & Installation
Follow these steps to properly install your PCCOOLER 120mm case fans.
3.1 Unpacking the Contents
Carefully remove all components from the packaging. The package typically includes:
- 3 x 120mm PCCOOLER Fans
- RGB Controller (if included in your specific kit)
- Mounting Screws
- Cables for power and RGB connection

3.2 Fan Placement and Mounting
Determine the optimal placement for your fans within your PC case for effective airflow. Fans can be used for intake (bringing cool air in) or exhaust (expelling hot air out).

3.3 Wiring Connections
Each fan has two cables: a 4-pin PWM connector for power and speed control, and a 5V 3-pin ARGB connector for lighting.

- Connect PWM Cables: Connect the 4-pin PWM cables from each fan to the fan headers on your motherboard or to the included fan controller. The intelligent temperature control module will manage fan speeds between 1000-1800 RPM.
- Connect ARGB Cables: Connect the 5V 3-pin ARGB cables from each fan to the ARGB headers on your motherboard or to the included RGB controller.
- Controller Connection (if applicable): If using the included controller, connect the fans to the controller and then connect the controller to your power supply (via Molex) and motherboard (for ARGB sync, if desired).
These fans are also suitable for water cooling setups and support 120/240/360mm radiators.

4. Operation
Once installed and connected, you can control the fan speed and lighting effects.
4.1 Fan Speed Control (PWM)
The fans utilize PWM (Pulse Width Modulation) technology, allowing your motherboard to dynamically adjust fan speed based on system temperature. This ensures efficient cooling when needed and quiet operation during lighter loads. You can configure fan curves in your motherboard's BIOS/UEFI settings or through compatible software.
4.2 RGB Lighting Control
The dual light loop design offers extensive customization for lighting effects.

- Motherboard Synchronization: If connected to a compatible 5V 3-pin ARGB header on your motherboard, you can control the lighting using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion).
- Controller Operation: If your motherboard does not support ARGB or you prefer standalone control, use the included wired RGB LED controller. This controller offers 10 lighting modes, 6 different colors, and multiple RGB light speeds.

To switch between motherboard control and controller control, refer to the specific instructions for your controller or motherboard software. Some controllers may require holding a "Lock" button to save settings or relinquish control to the motherboard.
5. Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your fans.
- Cleaning: Periodically clean the fan blades and housing to remove dust buildup. Use compressed air or a soft, dry cloth. Ensure the computer is powered off and unplugged before cleaning.
- Inspection: Check cables for any signs of wear or damage. Ensure all connections remain secure.
- Bearing Longevity: The hydraulic bearings are designed for a long lifespan (30,000 hours) and typically do not require lubrication.
6. Troubleshooting
If you encounter issues with your PCCOOLER fans, refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Fans not spinning | Loose or incorrect power connection (4-pin PWM). | Ensure all 4-pin PWM cables are securely connected to the motherboard or controller. Check PSU connections. |
| RGB lights not working or flickering | Incorrect ARGB connection (5V 3-pin) or incompatible voltage. Controller issue. | Verify 5V 3-pin ARGB cables are correctly connected to a 5V header (not 12V). If using a controller, ensure it's powered and functioning. Try re-seating connections. |
| Fans are too loud | High RPM settings, fan curve configuration, or vibration. | Adjust fan speed settings in BIOS/UEFI or motherboard software. Ensure fans are securely mounted and silicone pads are in place to reduce vibration. |
| RGB colors are inconsistent or not syncing | Software conflict, incorrect controller mode, or faulty connection. | Ensure only one RGB control software is active. If using a controller, verify it's in motherboard sync mode (if desired) or use its remote to set colors. Check ARGB cable integrity. |
