4. Setup and Installation

This section provides general guidelines for installing your AeroCool Oasis L240 ARGB AIO Liquid CPU Cooler. For detailed, step-by-step instructions, please refer to the separate installation guide included with your product or available on the AeroCool website.

4.1. Pre-Installation Checklist

• Ensure your PC case has adequate space for a 240mm radiator (typically top or front mounting).
• Verify your motherboard's CPU socket type (Intel LGA 1700, 1200, 115X, 1851, 1366 or AMD AM5/AM4) and prepare the corresponding mounting hardware.
• Gather necessary tools: Phillips head screwdriver, thermal paste (if not pre-applied).
• Power off your computer and disconnect all cables before beginning installation.

4.2. Installation Steps (General)

1. Prepare CPU Socket: Install the correct backplate (for Intel) or retention clips (for AMD) onto your motherboard as per your CPU socket type.
2. Apply Thermal Paste: If thermal paste is not pre-applied to the cold plate, apply a small pea-sized amount to the center of your CPU's Integrated Heat Spreader (IHS).
3. Mount Pump/Cold Plate: Carefully align the pump/cold plate assembly with the CPU and secure it using the appropriate mounting screws. Ensure even pressure.
4. Mount Radiator: Install the 240mm radiator and its pre-attached fans into your chosen mounting location within the PC case (e.g., top, front). Secure with screws.
5. Connect Cables:
   • Connect the pump's 4-pin power connector to an available CPU_FAN or AIO_PUMP header on your motherboard.
   • Connect the ARGB cables from the fans and pump to a compatible 3-pin 5V ARGB header on your motherboard or an ARGB controller.
   • Connect the fan power cables to available fan headers on your motherboard.
6. Cable Management: Route cables neatly to ensure proper airflow and a clean build.

5. Operating Instructions

Once installed, the AeroCool Oasis L240 ARGB AIO Liquid CPU Cooler operates automatically to maintain optimal CPU temperatures. Here's what to expect and how to manage its functions:

5.1. Automatic Operation

The cooler's pump and fans are designed to adjust their speed based on CPU temperature, as controlled by your motherboard's BIOS/UEFI settings or fan control software. This ensures efficient cooling when needed and quieter operation during lighter loads.

• Cooling Method: Water-based liquid cooling system.
• Maximum Rotational Speed: Fans can reach up to 2200 RPM for maximum cooling performance.
• Noise Level: Operates at approximately 36 dB under typical load, providing a balance between cooling and acoustics.

5.2. ARGB Lighting Control

The ARGB lighting on the pump and fans can be controlled via:

• Motherboard Software: If connected to a compatible 3-pin 5V ARGB header, you can use your motherboard manufacturer's RGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome Sync) to customize lighting effects and synchronize them with other components.
• ARGB Controller: If your system does not have a compatible motherboard header, an external ARGB controller (sold separately or included with some PC cases) can be used to manage lighting.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your AeroCool Oasis L240 ARGB AIO Liquid CPU Cooler.

• Dust Cleaning: Periodically inspect the radiator fins and fan blades for dust accumulation. Use compressed air or a soft brush to gently remove dust. Excessive dust can impede airflow and reduce cooling efficiency.
• Fan Inspection: Check fan blades for any obstructions or signs of wear. Ensure fans spin freely and quietly.
• Tubing and Connections: Visually inspect the tubing and connections for any signs of leaks, kinks, or damage. While AIO coolers are sealed systems, regular checks are advisable.
• Thermal Paste: The thermal paste applied between the CPU and the cold plate typically lasts for several years. Reapplication is generally not necessary unless the cooler is removed or reinstalled. If reapplication is needed, clean both surfaces thoroughly before applying new thermal paste.

Note: Do not attempt to open the sealed liquid loop of the AIO cooler. This will void the warranty and can lead to system damage.
