2. Product Features
- Addressable RGB PWM Silent Fan: Features a 120mm 5V 3-Pin addressable RGB and 12V 4-Pin PWM fan. The fan utilizes a SilentPro blade design with a Corona LED frame to enhance air convection and heat dissipation. It supports automatic speed control from 1000 to 2000 RPM (±10%) and includes shockproof rubber pads for reduced noise.
- Definable RGB LED Acrylic Top Guard: An acrylic top guard with definable RGB LEDs syncs with the FRGB fan lights or motherboard, offering various lighting effects including rainbow and solid color modes. An included RGB controller provides 6 different solid colors and 10 lighting modes.
- Black Plating Anti-oxidation Protective Layer: The GI-D56A HALO FRGB CPU cooler features a black plating anti-oxidation protective layer, ensuring optimal light transmission and preventing glare. The acrylic material offers excellent weatherability, high surface hardness, and good high-temperature performance.
- 5 Heat Pipes Direct Touch and Super Heat Dissipation (160W TDP): Equipped with 5 pieces of 6mm nickel-plated copper powder heat pipes (3 U-type + 2 L-type) for rapid thermal conduction. The 45x38mm aluminum heat base with HDT (Heat pipes Direct Touch) ensures direct contact with the CPU for efficient and quick heat transfer, supporting up to 160W TDP.
- Universal Metal EasySET Pro Bracket: Compatible with a wide range of Intel sockets (LGA2066 / 2011 / 1150 / 1151 / 1155 / 1156 / 775 / 1366) and AMD sockets (AM4 / FM2+ / FM2 / FM1 / AM3+ / AM3 / AM2+ / AM2). This metal bracket ensures stable installation and protects the motherboard from bending or deformation.
3. Package Contents
Please verify that all components are present in the package:
- CPU Cooler (Radiator with pre-installed fan)
- Mounting Brackets for Intel and AMD sockets
- Backplate
- Screws and Spacers
- Thermal Paste
- RGB Controller (if not using motherboard sync)
- User Manual (this document)
4. Setup and Installation
Before beginning installation, ensure your computer is powered off and unplugged. It is recommended to consult your motherboard manual for specific CPU cooler installation guidelines. Always refer to the detailed instructions provided with the cooler for your specific CPU socket type.
4.1 General Installation Steps
- Prepare Motherboard: Identify the correct mounting hardware for your CPU socket (Intel LGA or AMD AM/FM series). Attach the appropriate backplate to the rear of your motherboard.
- Apply Thermal Paste: Clean the surface of your CPU and apply a thin, even layer of thermal paste to the CPU's integrated heat spreader (IHS).
- Mount Cooler: Carefully place the CPU cooler onto the CPU, aligning the mounting holes with the standoffs on the motherboard. Secure the cooler using the provided screws, tightening them in a cross pattern to ensure even pressure.
- Connect Fan and RGB Cables: Connect the 4-pin PWM fan cable to the CPU_FAN header on your motherboard. Connect the 3-pin ARGB cable to a compatible 5V ARGB header on your motherboard, or to the included RGB controller.
- Cable Management: Route cables neatly to avoid interference with other components or airflow.

5. Operating Instructions
5.1 Fan Speed Control (PWM)
The 120mm fan supports Pulse Width Modulation (PWM) for automatic speed control. Connect the 4-pin fan connector to your motherboard's CPU_FAN header. Your motherboard's BIOS/UEFI settings or dedicated software can be used to configure fan curves, allowing the fan speed to adjust based on CPU temperature, optimizing for either performance or silence.
5.2 ARGB Lighting Control
The GI-D56A features addressable RGB (ARGB) lighting on both the fan and the top cover. There are two primary methods for controlling the lighting:
- Motherboard Synchronization: If your motherboard has a compatible 5V 3-Pin ARGB header, connect the cooler's ARGB cable to it. You can then control the lighting effects using your motherboard's RGB software (e.g., ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync).
- Included RGB Controller: If your motherboard lacks a 5V 3-Pin ARGB header, use the provided wired RGB LED controller. This controller allows you to switch between 6 different solid colors and 10 lighting modes, offering various aesthetic options.

6. Maintenance
Regular maintenance helps ensure optimal cooling performance and extends the lifespan of your CPU cooler.
- Dust Removal: Periodically clean the fan blades and heatsink fins to remove accumulated dust. Use compressed air or a soft brush. Ensure the fan is not spinning rapidly during cleaning to prevent damage to the bearings.
- Thermal Paste: While not required frequently, if you remove the cooler for any reason, it is recommended to clean off old thermal paste from both the CPU and the cooler's base and apply fresh thermal paste before reinstallation.
- Cable Check: Ensure all cables (fan, RGB) are securely connected and not obstructing airflow.
7. Troubleshooting
If you encounter issues with your PCCOOLER GI-D56A CPU Cooler, refer to the following common troubleshooting steps:
- High CPU Temperatures:
- Verify the cooler is securely mounted and making proper contact with the CPU.
- Ensure thermal paste was applied correctly and is not dried out.
- Check if the fan is spinning. If not, ensure the fan cable is properly connected to the CPU_FAN header.
- Clean any dust buildup from the heatsink fins and fan blades.
- Confirm adequate airflow within your PC case.
- Fan Not Spinning or Making Unusual Noise:
- Check the 4-pin PWM fan connection to the motherboard.
- Inspect the fan blades for any obstructions.
- If the fan is making excessive noise, ensure it is securely mounted and not vibrating against other components.
- RGB Lighting Not Working or Incorrect:
- Verify the 3-pin ARGB cable is correctly connected to either the motherboard's 5V ARGB header or the included RGB controller.
- If using motherboard sync, ensure your motherboard's RGB software is installed and configured correctly.
- If using the RGB controller, ensure it is powered and functioning.
- Note: This cooler uses 5V ARGB. Do not connect it to a 12V RGB header, as this can cause damage.
If problems persist, please contact PCCOOLER customer support for further assistance.
