Key Features & Cooling Technologies
38mm Premium Radiator
The 317 × 138 × 38mm aluminium radiator provides a larger cooling surface and increased radiator thickness for high-load CPU cooling applications.
P14 Pro A-RGB Fans
Two 140mm P14 Pro A-RGB fans operate from 400 to 2500 RPM, delivering up to 110 CFM airflow and 5.2 mmH₂O static pressure.
Integrated VRM Fan
A dedicated PWM-controlled VRM fan directs airflow toward the motherboard voltage-regulation area, helping manage VRM temperatures during sustained workloads.
Offset CPU Mounting
ARCTIC's offset mounting design positions the copper cold plate toward the CPU hotspot for more targeted heat transfer on compatible platforms.
A-RGB Gen2 Lighting
The cooler incorporates 12 A-RGB Gen2 LEDs with a standard 3-pin A-RGB connection for motherboard-based lighting control.
Integrated Cable Management
Fan wiring is integrated into the sleeving to reduce cable clutter and keep the installation cleaner around the radiator and motherboard.
Platform & Installation Technologies
The Liquid Freezer III Pro 280 A-RGB is designed around modern AMD and Intel desktop platforms, with flexible PWM control and separate A-RGB connectivity.
Technical Specifications
Who Is the ARCTIC Liquid Freezer III Pro 280 A-RGB For?
Gaming PCs
Suitable for gaming builds using modern high-performance AMD Ryzen and Intel Core processors where a 280mm AIO fits the selected cabinet.
Content Creation
A practical option for video editing, 3D rendering, development and other sustained CPU workloads that benefit from capable liquid cooling.
High-Performance Desktops
The 280mm radiator, P14 Pro fans and integrated VRM fan make it suitable for performance-focused desktop configurations with sufficient radiator clearance.
A-RGB Builds
The 3-pin A-RGB connection makes it suitable for builds where coordinated motherboard-controlled lighting is part of the system design.
Before You Build
Check radiator clearance: The Liquid Freezer III Pro 280 A-RGB uses a 317 × 138 × 38mm radiator, with the complete radiator-and-fan assembly requiring approximately 68mm of thickness. Confirm your cabinet's 280mm radiator support and available clearance before purchase.
Check motherboard clearance: ARCTIC specifies a minimum installation clearance of 63mm. Certain motherboards may have limited compatibility because of oversized SSD heatsinks around the M.2_1 slot.
Check A-RGB support: The lighting uses a standard 3-pin 5V A-RGB connection. Do not connect the A-RGB plug to a 12V 4-pin RGB header.
Platform compatibility: Designed for AMD AM4/AM5 and Intel LGA1700/LGA1851 desktop platforms. Always verify the exact motherboard and cabinet clearance before installation.
