With support for AMD AM4/AM5 and Intel LGA1700/LGA1851, integrated cable management, 450mm tubing and included MX-6 thermal compound, the Liquid Freezer III Pro 240 A-RGB is designed for a clean installation in modern PC builds.
Key Features & Cooling Technologies
Premium 38mm Radiator
The 240mm aluminium radiator measures 277 × 120 × 38mm and holds more coolant than conventional 27mm radiators for efficient handling of CPU heat and temperature spikes.
P12 Pro A-RGB Fans
Two 120mm P12 Pro A-RGB fans operate from 600 to 3000 RPM, delivering up to 77 CFM airflow and 6.9 mmH₂O static pressure.
Integrated VRM Fan
A dedicated PWM-controlled VRM fan operates from 400 to 2500 RPM and directs airflow toward the motherboard voltage-regulation area.
Offset CPU Mounting
ARCTIC's offset mounting design shifts the cold plate toward the CPU hotspot on compatible AMD and Intel platforms for targeted heat transfer.
Intel Contact Frame
The included Intel contact frame is designed to optimize contact pressure distribution on compatible Intel processors and improve cooler mounting consistency.
A-RGB Gen2 Lighting
Twelve A-RGB Gen2 LEDs provide customizable lighting through a standard 3-pin 5V A-RGB connection compatible with supported motherboard lighting systems.
Platform & Installation Technologies
The Liquid Freezer III Pro 240 A-RGB combines modern CPU socket compatibility with PWM control, integrated VRM cooling, offset mounting and motherboard-controlled A-RGB lighting.
Technical Specifications
Who Is the ARCTIC Liquid Freezer III Pro 240 A-RGB For?
Gaming PCs
Suitable for gaming systems using modern AMD Ryzen or Intel Core processors where the cabinet supports a 240mm radiator.
Compact Performance Builds
The 240mm radiator provides a practical liquid-cooling format for performance-focused cases where larger 280mm, 360mm or 420mm radiators may not fit.
Content Creation
Suitable for video editing, rendering, development and other CPU-intensive workloads when paired with a compatible processor and chassis.
A-RGB PC Builds
The integrated A-RGB lighting provides customizable illumination for builds using compatible 5V 3-pin motherboard lighting headers.
Before You Build
Check radiator clearance: The radiator measures 277 × 120 × 38mm and the complete radiator-and-fan assembly is approximately 66mm thick. Confirm that your cabinet supports a 240mm radiator.
Check motherboard clearance: ARCTIC specifies a minimum 63mm installation clearance. Some motherboards may have compatibility limitations because of oversized M.2_1 SSD heatsinks.
Check A-RGB support: The lighting uses a standard 3-pin 5V A-RGB connection. Do not connect it to a 12V 4-pin RGB header.
Check PWM connections: The pump, VRM fan and radiator fans can be controlled together or individually depending on the motherboard header configuration and included cable setup.
Platform compatibility: Supports AMD AM4/AM5 and Intel LGA115x, LGA1200, LGA1700 and LGA1851 platforms. Verify the exact motherboard and cabinet before installation.
