Setup and Installation

Follow these steps for proper installation of the Pure Loop 2 FX 360mm liquid cooler. Refer to your motherboard and PC case manuals for specific guidance on component placement and cable routing.

1. Prepare the CPU Socket

Identify your CPU socket type (Intel or AMD) and prepare the appropriate backplate and mounting brackets. Clean the CPU surface with isopropyl alcohol to remove any residue.

2. Install Radiator and Fans

Mount the three Light Wings 120mm PWM fans to the radiator using the provided screws. Ensure the fan airflow direction is appropriate for your case's cooling configuration (intake or exhaust). Secure the assembled radiator and fans into your PC case. The 360mm radiator typically mounts to the front or top of compatible cases.

3. Apply Thermal Paste

Apply a small amount of the included thermal paste to the center of your CPU's Integrated Heat Spreader (IHS). A pea-sized dot or a thin line is generally sufficient.

4. Mount the CPU Block

Carefully place the CPU block onto the CPU, aligning it with the mounting holes. Secure it with the appropriate screws and brackets for your socket type. Tighten screws in a diagonal pattern until snug, but do not overtighten.

• Intel Socket Compatibility: 1700 / 1200 / 2066 / 1150 / 1151 / 1155 / 2011(-3) Square ILM
• AMD Socket Compatibility: AM5 / AM4

5. Connect Cables

Connect the pump's 3-pin power cable to a dedicated AIO_PUMP or CPU_FAN header on your motherboard. Connect the fan PWM cables and ARGB cables to the included ARGB-PWM-Hub. Connect the ARGB-PWM-Hub to a motherboard PWM fan header and a 5V ARGB header for synchronization.

Operating Instructions

Once installed, the Pure Loop 2 FX 360mm operates automatically based on your motherboard's fan and pump control settings.

• PWM Control: The pump and fans are PWM controlled. You can adjust their speed curves via your motherboard's BIOS/UEFI settings or through compatible software. It is recommended to set the pump to run at 100% or a high fixed speed for optimal cooling performance and longevity.
• ARGB Illumination: The Light Wings fans and CPU block feature ARGB illumination. Connect the ARGB-PWM-Hub to a 5V ARGB header on your motherboard. Use your motherboard's ARGB software (e.g., ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, ASRock Polychrome Sync) to customize lighting effects and synchronize them with other ARGB components.

Maintenance

The Pure Loop 2 FX 360mm is designed for long-term, low-maintenance operation. However, periodic checks and refilling are recommended.

• Dust Cleaning: Periodically clean dust from the radiator fins and fan blades using compressed air or a soft brush to maintain optimal airflow and cooling performance.
• Coolant Refill: The radiator features an easy-to-access refill port. Over time, a small amount of coolant may evaporate. If you notice a decrease in cooling performance or hear unusual pump noises, you may need to top up the coolant. Use only the provided coolant bottle or a compatible, high-quality AIO coolant.

Troubleshooting

If you encounter issues with your Pure Loop 2 FX 360mm, consider the following common solutions:

• No Power/No Lights:
  • Check all power connections to the pump, fans, and ARGB-PWM-Hub.
  • Ensure the ARGB-PWM-Hub is connected to a 5V ARGB header on the motherboard.
  • Verify motherboard BIOS settings for fan and pump headers.
• High CPU Temperatures:
  • Confirm the CPU block is securely mounted and making good contact with the CPU.
  • Check if thermal paste was applied correctly.
  • Ensure fans are spinning and oriented correctly for optimal airflow.
  • Verify pump is running at an adequate speed (check BIOS/software).
  • Inspect radiator for dust buildup and clean if necessary.
  • Check coolant level via the refill port.
• Unusual Noise:
  • Identify the source of the noise (fans or pump).
  • If from fans, check for obstructions or adjust fan speed curves.
  • If from the pump (gurgling/whining), it may indicate air in the loop or low coolant. Try gently tilting the PC case to dislodge air bubbles, or consider refilling coolant.
