ARCTIC Liquid Freezer III Pro 360 AIO CPU Water Cooler — 360mm | 3× P12 Pro Fans | VRM Fan | Intel LGA1851/1700 | AMD AM5/AM4 | Black (ACFRE00180A)

The ARCTIC Liquid Freezer III Pro 360 is built for enthusiast gamers, overclockers, content creators, and performance system builders deploying high-TDP processors — including Intel Core Ultra Series 2, Intel Core i9-14900K, AMD Ryzen 9 9950X3D, and similar flagship CPUs — who demand exceptional thermal performance, quiet operation at load, and a refined build experience in a 360mm AIO format. It is well-suited for high-end gaming builds, streaming workstations, content creation systems, overclocked flagship CPU deployments, and any system where sustained peak CPU performance requires a premium liquid cooling solution.

The Liquid Freezer III Pro 360 features a premium 38mm thick radiator — 11mm thicker than standard 27mm AIOs — holding more liquid for reduced heat buildup, greater thermal mass, and more efficient handling of sustained high-TDP temperature spikes during prolonged gaming and workload sessions. Three ARCTIC P12 Pro fans with Fluid Dynamic Bearings deliver class-leading static pressure at 6.9 mmH2O and airflow at 77 cfm / 131 m³/h across the full 600–3000 RPM speed range — providing quiet, efficient cooling at low-to-medium speeds and exceptional high-load performance when needed. The integrated PWM-controlled VRM fan on the pump head actively cools the motherboard's voltage regulator modules during CPU-intensive workloads — a design decision that directly improves VRM thermal headroom and long-term motherboard reliability under sustained overclocked operation. Offset mounting shifts the cold plate position toward the CPU die hotspot on both Intel and AMD platforms, improving CPU-to-cold-plate heat transfer efficiency at the contact interface. The Intel Contact Frame replaces the standard Intel mounting mechanism to provide optimised contact pressure distribution across the CPU IHS for improved heat dissipation and reduced CPU bend risk under sustained clamping force. Integrated cable management routes all fan cables inside the braided sleeving of the tubing for a clean, clutter-free installation without loose cables hanging across the radiator. Two control options — a splitter cable for independent pump, VRM fan, and radiator fan control, or an all-in-one cable for single-PWM-signal synchronised control — provide flexibility for different motherboard fan header configurations. Pre-installed MX-6 thermal paste with cross-pattern application guide simplifies first-time installation. Reinforced EPDM tubing with braided sheathing at 450mm length provides durability and flexibility for varied case configurations. Minimum 63mm case clearance required for installation — verify case compatibility via ARCTIC's online compatibility check tool.
