2. Product Overview and Components
The Frozen Magic 240 Black ARGB V2 AIO cooler consists of a radiator, two 120mm ARGB fans, a water block with an integrated pump, and connecting tubes. Key features include:
- Efficient Cooling: Features a full purple copper mirror plane base, a 240mm black aluminum fin radiator, and polymer-protected water pipes for low resistance and high thermal efficiency.
- ARGB Synchronization: The CPU fan and water-cooling header ARGB lighting synchronize with your motherboard's 5V 3-pin ARGB header, offering extensive lighting effects.
- Dual PWM Fans: Equipped with two TL-C12B-S V2 fans, offering speeds up to 1600 RPM, low noise operation (≤28 dBA), and S-FDB bearings for durability.
- Wide Compatibility: Supports a broad range of Intel (LGA 1150/1151/1155/1156/1200/1700/2011/2066) and AMD (AM5/AM4/AM3/AM3+/AM2/AM2+/FM1/FM2/FM2+) sockets.

3. Safety Information
Please observe the following safety guidelines during installation and operation:
- Ensure your computer system is powered off and unplugged from the wall outlet before beginning installation.
- Handle components with care to avoid damage.
- Refer to your motherboard manual for specific header locations and power connections.
- Do not attempt to open or modify the AIO unit, as this may void the warranty and cause damage.
- Keep the product away from liquids and extreme temperatures.
4. Setup and Installation
The installation process involves mounting the radiator, fans, and water block to your CPU. Ensure your chassis has adequate space for a 240mm radiator. A chassis width greater than 250mm is recommended.
4.1. Package Contents
Verify that all components are present:
- Thermalright Frozen Magic 240 Black ARGB V2 AIO Water Cooler (Radiator, Pump/Water Block, 2x Fans pre-mounted)
- Mounting hardware for Intel sockets (LGA 1150/1151/1155/1156/1200/1700/2011/2066)
- Mounting hardware for AMD sockets (AM5/AM4/AM3/AM3+/AM2/AM2+/FM1/FM2/FM2+)
- Y-adapter cable for fan power
- ARGB connection cable
- Thermal paste (pre-applied or included)
4.2. Motherboard Compatibility

4.3. General Installation Steps
- Prepare the CPU: Clean the CPU surface thoroughly, removing any old thermal paste.
- Install Backplate (if required): For Intel sockets, install the appropriate backplate behind the motherboard. AMD AM4/AM5 typically uses the stock backplate.
- Mount Standoffs: Screw the correct standoffs for your CPU socket onto the backplate or motherboard.
- Apply Thermal Paste: If not pre-applied, apply a small amount of thermal paste to the center of the CPU's integrated heat spreader (IHS).
- Mount Water Block: Carefully place the water block onto the CPU, aligning the mounting holes with the standoffs. Secure it with the provided thumb screws or nuts, tightening in a diagonal pattern until snug.
- Install Radiator: Mount the 240mm radiator to an available fan mount location in your chassis (e.g., top, front). Ensure proper airflow direction.
- Connect Fans: The fans are typically pre-mounted to the radiator. Connect both fan power cables to the provided Y-adapter cable, then connect the Y-adapter to your motherboard's CPU_FAN header.
- Connect ARGB: Connect the ARGB cables from the fans and water block to the motherboard's 5V 3-pin ARGB header. Note: This cooler only supports 5V 3-pin ARGB. Do NOT connect to a 12V 4-pin RGB header.

5. Operating Instructions
Once installed, the Thermalright Frozen Magic 240 Black ARGB V2 operates automatically. The fans and pump are controlled via PWM (Pulse Width Modulation) signals from your motherboard, adjusting speed based on CPU temperature.
5.1. ARGB Lighting Control
The Addressable RGB lighting on the fans and water block can be controlled through your motherboard's ARGB software (e.g., ASUS Aura Sync, MSI Mystic Light Sync, GIGABYTE RGB Fusion, ASRock Polychrome Sync). Ensure the 5V 3-pin ARGB header is correctly connected.

6. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your AIO cooler.
- Dust Removal: Periodically clean dust from the radiator fins and fan blades using compressed air. Ensure fans are not spinning during cleaning.
- Inspect Tubing: Check the water tubes for any signs of kinks, leaks, or damage. The polymer compilation protection helps prevent liquid evaporation.
- Thermal Paste: While not frequently required for AIOs, if you ever remove the water block from the CPU, you must clean off old thermal paste and apply new thermal paste before reinstallation.
