5. Setup and Installation
Follow these steps for proper installation of your AIO liquid cooler. Ensure your PC is powered off and unplugged before beginning.
Step 5.1: Prepare the Radiator and Fans
The 120mm ARGB fans are typically pre-installed on the radiator. If not, attach them using the provided screws, ensuring airflow direction is appropriate for your case (usually exhausting air out of the case).

Step 5.3: Prepare the CPU Socket
Install the appropriate backplate for your CPU socket (Intel or AMD) behind the motherboard. Then, attach the correct standoffs to the front of the motherboard around the CPU socket.
Step 5.4: Apply Thermal Paste
Clean the CPU surface with isopropyl alcohol. Apply a small, pea-sized amount of the included thermal paste to the center of your CPU's integrated heat spreader (IHS).
Step 5.5: Install the Pump Head
Carefully place the pump head onto the CPU, aligning the mounting holes with the standoffs. Secure the pump head with the provided thumb screws or nuts, tightening them in a diagonal pattern until snug. Do not overtighten.

Step 5.6: Connect Cables
- Pump Power: Connect the pump's 3-pin or 4-pin connector to the motherboard's AIO_PUMP or CPU_FAN header.
- Fan Power: Connect the fan cables to the motherboard's fan headers or a fan controller.
- ARGB Lighting: Connect the ARGB cables from the pump and fans to your motherboard's 5V 3-pin ARGB header or the included ARGB controller. Ensure correct pin alignment to avoid damage.
6. Operating Instructions
Once installed, power on your PC. The cooler will begin operating automatically.
Fan and Pump Speed Control
The fan and pump speeds are typically controlled via your motherboard's BIOS/UEFI settings or dedicated software provided by your motherboard manufacturer. Adjust fan curves to balance cooling performance and noise levels. The pump operates at a maximum rotational speed of 3100 RPM for optimal liquid circulation.
ARGB Lighting Control
The LightFlow ARGB cooler supports various motherboard ARGB synchronization technologies, including ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync, and ASRock Polychrome Sync. Connect the ARGB cable to your motherboard's 5V 3-pin header and use the motherboard's software to customize lighting effects. If an external ARGB controller is included, use its buttons to cycle through lighting modes.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your liquid cooler.
- Dust Cleaning: Periodically clean dust from the radiator fins and fan blades using compressed air. Ensure fans are held stationary during cleaning to prevent damage.
- Inspect Tubing: Check the tubing for any signs of kinks, leaks, or damage.
- Pump Check: Listen for any unusual noises from the pump, which could indicate an issue.
- Thermal Paste: While not frequently required for AIOs, if you remove the pump head, reapply thermal paste before reinstallation.
