Arctic Liquid Freezer III Pro 280 ARGB CPU Liquid Cooler

The ARCTIC Liquid Freezer III Pro 280 ARGB (SKU: ACFRE00183A) is a 280 mm all-in-one CPU liquid cooler designed for enthusiast desktop builds that demand reliable thermal performance alongside addressable RGB lighting. At the heart of the cooler sits a copper cold plate machined with micro-skived fins, engineered to maximise surface contact and heat transfer efficiency. ARCTIC's offset mounting system shifts this cold plate toward the CPU's primary heat source, improving thermal coupling without requiring additional user adjustment. The 38 mm thick aluminium radiator sets this unit apart from many competing 280 mm AIOs that use a shallower 27 mm profile. The added depth accommodates more coolant volume, which helps the system handle sustained thermal spikes more effectively. Two pre-installed ARCTIC P14 Pro A-RGB fans drive airflow through the radiator, each spinning between 400 and 2500 RPM via 4-pin PWM control and delivering up to 110 CFM (186 m³/h) of airflow with 5.2 mmH₂O of static pressure. A notable feature exclusive to the Pro series is the integrated VRM fan, a PWM-controlled secondary fan mounted on the pump head that directs airflow toward the motherboard's voltage regulator modules. This assists in stabilising VRM temperatures under sustained CPU loads, a practical benefit for users running power-hungry processors without supplementary airflow in that zone. Coolant is circulated by a pump operating between 800 and 2800 RPM under PWM control. The reinforced EPDM tubing with braided outer sheathing (450 mm length, 12.4 mm outer / 6.0 mm inner diameter) is designed for long-term flexibility and resistance to degradation. For Intel LGA1700 and LGA1851 platforms, an Intel Contact Frame is included to optimise mounting pressure and improve heat dissipation while reducing stress on the CPU substrate. Lighting is provided by 24 A-RGB Gen2 LEDs in total — 12 on each P14 Pro fan — operating at 5 V DC via 3-pin A-RGB connectors with pass-through sockets for daisy-chaining. A splitter cable gives users the option to control the pump, VRM fan, and radiator fans independently or synchronise all outputs through a single PWM signal using the included all-in-one cable. ARCTIC bundles MX-6 thermal paste and provides an animated online installation guide. Installation is tool-friendly with pre-wired, pre-installed fans. The cooler carries a 6-year manufacturer warranty.
