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

The ARCTIC Liquid Freezer III 240mm ARGB (Model: ACFRE00142A) is a 240mm all-in-one CPU liquid cooler designed for enthusiasts who want strong thermal performance, a clean build, and flexible lighting control — all in a single, well-engineered package. At the heart of the cooler is a PWM-controlled pump running between 800 and 2800 rpm, drawing 0.35 A at 12 V DC. The copper cold plate uses micro-skived fins to maximise heat transfer from the CPU to the liquid loop. Braided tubes measure 450 mm in length, with a 12.4 mm outer and 6.0 mm inner diameter, giving the loop adequate volume and routing flexibility inside a mid-tower case. The 38 mm thick aluminium radiator features an extended fin stack that increases cooling surface area, allowing the system to handle sustained power spikes more effectively. Two ARCTIC P12 PWM PST A-RGB fans come pre-installed in a push configuration, spinning between 200 and 2000 rpm. Each fan delivers up to 48.82 CFM of airflow at 1.85 mmH2O static pressure, making the P-series fans well-suited to the dense fin density of the radiator. Fluid dynamic bearings keep acoustic output low over extended use. A 60 mm PWM VRM fan (400–2500 rpm, 0.05 A at 12 V DC) is mounted on the pump head to direct airflow over the motherboard's voltage regulation circuitry — especially useful in high-load or overclocking scenarios where passive cooling of the VRM area is insufficient. Lighting is handled by 12 addressable A-RGB LEDs using a standard 3-pin connector, compatible with most motherboard lighting ecosystems and software platforms. The daisy-chain design allows each LED to display an individual colour independently. Installation is simplified by cable routing integrated into the hose jacket. Two connection modes are provided: an all-in-one 4-pin PWM connector controls the entire unit via a single signal, while a splitter cable (3× 4-pin PWM) allows the pump, VRM fan, and radiator fans to be controlled independently. For Intel LGA1700 and LGA1851 platforms, ARCTIC includes a contact frame that reduces mechanical stress on the CPU and PCB. For AMD platforms, the mounting solution applies a 5 mm offset to align with the chiplet-based hot-spot location on AM4 and AM5 Ryzen processors. MX-6 thermal compound is included in the box.
