Arctic Liquid Freezer III Pro 240 ARGB CPU Liquid Cooler

The ARCTIC Liquid Freezer III Pro 240 ARGB is a 240 mm all-in-one CPU liquid cooler designed for enthusiast builders who want capable thermal performance, addressable RGB lighting, and broad platform compatibility in a single package. The cooler ships fully assembled with pre-installed, pre-wired fans, so installation is straightforward for builders at any skill level. An animated online manual guides you through every step. At the heart of the cooler sits a copper cold plate with micro-skived fins, engineered to maximise contact surface with the CPU heat spreader. ARCTIC’s offset-mounting system shifts the cold plate to align with the CPU’s primary hotspot, improving heat transfer efficiency. For Intel LGA1700 and LGA1851 platforms specifically, an Intel Contact Frame is included to optimise contact pressure distribution and reduce long-term stress on the CPU package. The 38 mm thick premium-class radiator provides greater internal volume than conventional 27 mm radiators, holding more coolant and smoothing out temperature spikes during sustained workloads. Coolant is carried through 450 mm reinforced EPDM tubes with braided sheathing, offering durability and flexibility during routing inside a variety of chassis. Two P12 Pro A-RGB fans handle radiator airflow. Each fan delivers up to 77 CFM (131 m³/h) of airflow with a static pressure rating of 6.9 mmH2O and operates across a PWM speed range of 600–3000 RPM, with the 4-pin connector allowing motherboard control. Each fan carries 12 A-RGB Gen 2 LEDs (3-pin A-RGB connector, 0.40 A at 5 V DC) for customisable lighting synchronised with supported motherboard software. A dedicated VRM fan, running 400–2500 RPM under PWM control, actively cools the voltage regulator module area on the motherboard — a feature particularly useful during heavy all-core loads. The cooler also includes ARCTIC’s MX-6 thermal paste, applied in a simple cross pattern that the pump’s cold plate distributes evenly at mount time. Two cable management options are provided: a splitter cable allows independent control of the pump, VRM fan, and radiator fans, while an all-in-one cable synchronises all components through a single PWM signal.
