Arctic Liquid Freezer III Pro 240mm CPU Liquid Cooler

The ARCTIC Liquid Freezer III Pro 240mm (ACFRE00178A) is a 240mm all-in-one CPU liquid cooler designed for enthusiasts who need reliable thermal management across both Intel and AMD platforms. Built around a thick 38mm aluminium radiator, it holds more coolant than conventional 27mm designs, helping absorb and dissipate heat spikes more effectively. The copper cold plate uses micro-skived fins to maximise surface contact with the CPU, and ARCTIC’s offset mounting shifts the cold plate toward the CPU hotspot for more efficient heat transfer on supported Intel socket builds. An Intel Contact Frame is included to distribute contact pressure more evenly, reducing long-term stress on the CPU. Two P12 Pro 120mm fans are pre-installed and pre-wired, spinning between 600 and 3000 RPM via PWM control. Each fan delivers up to 77 CFM of airflow at 6.9 mmH2O static pressure through fluid dynamic bearings, which contribute to low noise and long operating life. A dedicated VRM fan, running 400–2500 RPM on its own PWM signal, actively cools the motherboard voltage regulators — a practical advantage under sustained workloads. The pump operates between 800 and 2800 RPM under PWM control, keeping coolant flowing through 450mm EPDM tubes with braided outer sheathing for added durability. Installation is straightforward: fans arrive pre-attached to the radiator, cables are routed inside the sleeving, and an animated online manual guides the process step by step. A splitter cable lets the pump, VRM fan, and radiator fans be controlled independently through separate headers, while an all-in-one cable allows all components to be synchronised via a single PWM signal — giving builders flexibility to match their motherboard layout. Compatible sockets include LGA1700, LGA1851, AM4, and AM5, covering a broad range of current Intel Core, Intel Core Ultra, and AMD Ryzen processors. ARCTIC backs this cooler with a 6-year warranty.
