ARCTIC Liquid Freezer III Pro 240mm ARGB CPU Liquid Cooler ( Black ) ( Liquid Freezer 3 )

The ARCTIC Liquid Freezer III Pro 240mm ARGB (model ACFRE00182A) is an all-in-one CPU liquid cooler built around a 38 mm thick, 277 x 120 mm aluminium radiator that provides a larger cooling surface and greater coolant volume compared to standard 25 mm radiators. The copper cold plate uses micro-skived fins to maximise heat transfer between the CPU and the circulating liquid, while a PWM-controlled pump operating between 800 and 2800 rpm keeps flow rates matched to thermal demand. Two pre-installed ARCTIC P12 Pro A-RGB fans spin between 600 and 3000 rpm, delivering up to 77 cfm of airflow at 6.9 mmH₂O static pressure through the dense radiator fins. Fan cables are routed inside the braided hose sleeve, so only a single cable needs to connect to the motherboard header, keeping the build tidy. A dedicated 60 mm PWM VRM fan (400–2500 rpm, 0.05 A at 12 V DC) provides active airflow over motherboard voltage regulators — useful for high-load workloads or cases with restricted airflow. A-RGB Gen2 lighting is present on both the pump head and the radiator fans, each with 12 addressable LEDs drawing 0.40 A at 5 V DC. Connectivity uses a standard 3-pin A-RGB plug with pass-through socket, compatible with most motherboard RGB ecosystems and third-party software such as SignalRGB. Independent PWM control for the pump, VRM fan, and radiator fans is achieved through an included splitter cable with three separate connections. The cooler ships with a custom Intel Contact Frame for LGA1700 and LGA1851 sockets, designed to reduce CPU lid deformation caused by Intel's Independent Loading Mechanism. For AMD platforms, a 5 mm offset mounting solution shifts the cold plate to align with the hotspot on Ryzen multi-die chiplet processors. Supported sockets are Intel LGA1851 and LGA1700, and AMD AM5 and AM4. Minimum clearance of 63 mm is required for installation; users should verify RAM height and M.2 cooler dimensions before purchasing. MX-6 thermal compound (0.8 g) is included in the box. Tubes measure 450 mm in length with a 12.4 mm outer diameter and 6.0 mm inner diameter. Total unit weight is 1665 g. Operating ambient temperature range is 0–40 °C. The product is backed by a 6-year manufacturer warranty.
