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

The ARCTIC Liquid Freezer III Pro 240mm (model ACFRE00178A) is an all-in-one liquid CPU cooler built for enthusiasts who demand dependable thermal management without RGB lighting. Its 240mm aluminium radiator measures 277 × 120 × 38 mm and features a 38 mm thick fin stack, providing an increased surface area for heat dissipation and a larger internal liquid volume to absorb sudden temperature spikes during sustained workloads. Two 120mm P12 Pro fans with Fluid Dynamic Bearings are pre-installed on the radiator in a push configuration. Running from 600 to 3000 RPM via PWM control, they deliver up to 77 CFM of airflow at 6.9 mmH₂O static pressure, making them well-suited to the restricted airflow environment of a dense radiator fin stack. PWM cables for both fans are routed inside the braided hose sheathing, which greatly reduces cable clutter and leaves only a single visible cable running to the motherboard header. The copper cold plate uses micro-skived fins to maximise contact area with the CPU heat spreader. ARCTIC's native offset mounting system shifts the cold plate toward the primary CPU hotspot, optimising contact pressure on both Intel and AMD platforms. The pump operates between 800 and 2800 RPM under PWM control, drawing 0.35 A at 12 V DC, with 450 mm tubes (outer diameter 12.4 mm, inner 6.0 mm) providing adequate routing flexibility in most mid-tower and full-tower cases. A distinguishing feature of the Pro series is the integrated 60 mm VRM fan, which runs from 400 to 2500 RPM (PWM-controlled, 0.05 A at 12 V DC) and directs airflow directly at the motherboard's voltage regulator module. This supplemental cooling can improve VRM longevity and system stability under sustained heavy loads, particularly on boards with dense power delivery layouts. Intel socket support covers LGA1851 and LGA1700. AMD support covers AM5 and AM4. The cooler ships with ARCTIC MX-6 thermal compound (0.8 g), and the operating ambient temperature range is 0–40 °C. Total cooler weight is 1,675 g; packaged weight is 2.065 kg. ARCTIC backs this product with a 6-year manufacturer's warranty, reflecting confidence in the long-term durability of its pump, fans, and cold plate assembly.
