ARCTIC Liquid Freezer III Pro 280 AIO CPU Cooler
A high-capacity 280mm all-in-one CPU liquid cooler featuring a 38mm radiator, dual P14 Pro fans, integrated VRM cooling and offset CPU mounting.
ARCTIC Liquid Freezer III Pro 280: High-Capacity CPU Cooling
The ARCTIC Liquid Freezer III Pro 280 is a 280mm AIO CPU liquid cooler designed for high-performance desktop systems. It combines a 38mm-thick aluminium radiator with two high-performance P14 Pro 140mm fans, offering a larger radiator format and high airflow for demanding CPU workloads.
The cooler also integrates a dedicated PWM-controlled VRM fan above the CPU block, while ARCTIC's offset mounting positions the cold plate toward the CPU hotspot. It supports AMD AM5/AM4 and Intel LGA1851/LGA1700 platforms.
Key Features
38mm Premium-Class Radiator
The 317 × 138 × 38mm aluminium radiator is substantially thicker than conventional 27mm AIO radiators and holds more coolant for handling demanding thermal loads.
Dual P14 Pro Fans
Two 140mm P14 Pro 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 fan integrated into the CPU block directs airflow toward the motherboard VRM area to help manage local component temperatures.
Offset CPU Mounting
The cold plate is offset toward the CPU hotspot on supported AMD and Intel platforms for more direct contact with the primary heat-generating area.
Intel Contact Frame
The included mounting solution is designed for compatible Intel LGA1851 and LGA1700 processors with optimized contact pressure distribution.
Integrated Cable Management
Fan cables are integrated into the sleeving, helping keep installation cleaner and minimizing cable clutter around the radiator and motherboard.
Cooling Technology & Performance Hardware
Liquid Freezer III Pro 280 combines a thick radiator, high-airflow P14 Pro fans, a dedicated VRM fan and a copper micro-skived cold plate. The pump operates from 800–2800 RPM, while the radiator fans can reach 2500 RPM under PWM control.

Technical Specifications
Ideal Use Cases
High-Performance Gaming
Suitable for gaming systems using higher-power CPUs where the cabinet provides adequate 280mm radiator clearance.
Content Creation
Designed for systems running sustained CPU workloads such as video editing, rendering, encoding and software development.
Workstations
A strong option for multi-core desktop workstations requiring a larger liquid cooling radiator and high-airflow 140mm fans.
Modern AMD & Intel Builds
Supports current AM5 and LGA1851 platforms as well as AM4 and LGA1700, subject to motherboard and mounting compatibility.
Before You Build
- Confirm that your cabinet supports a 280mm radiator and has sufficient clearance for the 38mm-thick radiator.
- The complete radiator-and-fan assembly is approximately 68mm thick.
- ARCTIC specifies at least 63mm of clearance for installation.
- Check motherboard compatibility carefully, particularly around oversized M.2 heatsinks near the primary CPU socket.
- The cooler supports AM5, AM4, LGA1851 and LGA1700 with the appropriate mounting hardware.
- The package includes ARCTIC MX-6 thermal paste.
- Because this is a 280mm AIO, verify that the intended radiator mounting position supports 140mm-class fan spacing.
