Setup and Installation
Before beginning installation, ensure your system is powered off and disconnected from the power source. Refer to your motherboard and PC case manuals for specific guidance on component installation and clearances.
Compatibility Check
The LightFlow ARGB 360 supports the following CPU sockets:
- Intel: LGA 1700, LGA 1851
- AMD: AM4, AM5
Verify that your PC case has adequate space for a 360mm radiator (15.63"L x 4.72"W x 1.06"H) and the associated fans. The total height with fans is approximately 52mm (27mm radiator + 25mm fan thickness).

Installation Steps (General Guide)
- Prepare Mounting Hardware: Identify the correct mounting brackets and screws for your CPU socket (Intel or AMD).
- Install Backplate (if applicable): For Intel sockets, install the appropriate backplate behind the motherboard. AMD AM4/AM5 typically uses the stock backplate.
- Mount Radiator: Secure the 360mm radiator with its pre-installed fans to an available mounting location in your PC case (e.g., top, front). Ensure proper airflow direction.
- Apply Thermal Paste: If not pre-applied, apply a small amount of high-quality thermal paste to the center of your CPU's Integrated Heat Spreader (IHS).
- Install Pump/Cold Plate: Carefully place the pump/cold plate assembly onto the CPU, aligning it with the mounting studs. Secure it with the appropriate thumb screws or nuts until snug.
- Connect Cables:
- Connect the pump's 3-pin or 4-pin power cable to the CPU_FAN or AIO_PUMP header on your motherboard.
- Connect the fan power cables (typically 4-pin PWM) to available fan headers on your motherboard or a fan controller.
- Connect the ARGB cables (3-pin 5V) from the fans and pump to an ARGB header on your motherboard or a dedicated ARGB controller.
- Cable Management: Route all cables neatly to ensure optimal airflow and a clean build appearance.

Operating Instructions
Once installed, the MONTECH LightFlow ARGB 360 operates automatically based on your motherboard's fan and pump control settings. Ensure your motherboard's BIOS/UEFI settings are configured to control the CPU fan/pump headers appropriately.
ARGB Lighting Control
The Addressable RGB (ARGB) lighting on the pump and fans can be controlled via your motherboard's RGB software (e.g., ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light Sync, ASRock Polychrome Sync) if connected to a compatible 3-pin 5V ARGB header. Consult your motherboard manual for specific software and control instructions.
Performance Monitoring
Monitor your CPU temperatures using system monitoring software to ensure the cooler is functioning optimally. The pump operates at a maximum rotational speed of 3100 RPM, and the fans provide an air flow capacity of 78.73 Cubic Centimeters Per Minute (CFM) at a noise level of 28 Decibels.
Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your liquid cooler.
- Dust Cleaning: Periodically clean dust from the radiator fins and fan blades using compressed air or a soft brush. Ensure fans are not spinning during cleaning.
- Inspect Tubing: Occasionally check the tubing for any signs of kinks, damage, or leaks. While rare, early detection can prevent issues.
- Fan Operation: Ensure all fans are spinning freely and quietly. Replace any fans that become excessively noisy or stop functioning.
- Thermal Paste: Reapplying thermal paste every few years, or when reinstalling the cooler, can help maintain optimal thermal transfer.
