Setup and Installation
Follow these steps carefully to install your AeroCool Mirage L240 ARGB Liquid Cooler.
1. Prepare Your System
- Power off your computer and unplug it from the wall outlet.
- Open your PC case and remove any existing CPU cooler.
- Clean the CPU surface thoroughly with isopropyl alcohol to remove old thermal paste.
2. Install Radiator and Fans
- Attach the two 120mm ARGB fans to the radiator using the long fan screws provided. Ensure the fan airflow direction is as desired (typically exhaust out of the case or intake into the case).
- Mount the radiator assembly to an available 240mm fan mount location in your PC case (e.g., top, front, or rear). Use the shorter radiator screws to secure it.

3. Install CPU Pump/Cold Plate
- Select the appropriate mounting brackets for your CPU socket (Intel or AMD) from the hardware kit. Attach them to the pump unit.
- If thermal paste is not pre-applied, apply a small pea-sized amount to the center of your CPU's integrated heat spreader (IHS).
- Carefully place the pump/cold plate assembly onto the CPU, aligning the mounting holes.
- Secure the pump to the motherboard using the provided thumb screws or nuts, tightening them in a diagonal pattern until snug. Do not overtighten.

4. Connect Cables
- Connect the pump's 3-pin power cable to the "CPU_FAN" or "AIO_PUMP" header on your motherboard.
- Connect each fan's 4-pin PWM cable to available fan headers on your motherboard (e.g., "SYS_FAN").
- Connect the ARGB cables from the fans and pump to your motherboard's 3-pin 5V ARGB header or to the included ARGB controller. Ensure correct polarity to avoid damage.
- Organize cables for good airflow and aesthetics.
Operating Instructions
Once installed, the AeroCool Mirage L240 ARGB Liquid Cooler operates automatically based on your motherboard's fan control settings. The pump runs continuously to circulate coolant, and fan speeds adjust according to CPU temperature.
ARGB Lighting Control
- Motherboard Sync: If connected to a compatible motherboard ARGB header, you can control the lighting effects using your motherboard's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome Sync).
- ARGB Controller: If using the included ARGB controller (if applicable), refer to its specific instructions for changing lighting modes, colors, and brightness.
Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your liquid cooler.
- Dust Cleaning: Periodically (every 3-6 months, or more often in dusty environments) power off your PC and use compressed air to clean dust from the radiator fins and fan blades. This prevents airflow restriction and maintains cooling efficiency.
- Visual Inspection: Check the tubing and connections for any signs of leaks or damage. While rare, early detection can prevent issues.
- Fan Operation: Ensure all fans are spinning freely and quietly. Replace any fans that become noisy or stop working.
