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

The ARCTIC Liquid Freezer III Pro 240mm ARGB (model ACFRE00186A) is an all-in-one liquid CPU cooler finished in white, combining thermal efficiency with addressable RGB aesthetics. At its core sits an aluminium radiator measuring 277 mm × 120 mm × 38 mm — a 38 mm thickness that provides an enlarged cooling surface and greater coolant volume compared to standard 25 mm radiators, helping the unit absorb and dissipate heat from demanding workloads more effectively. The copper cold plate uses micro-skived fin technology to maximise contact area with the CPU's integrated heat spreader. Tube length is 450 mm (outer diameter 12.4 mm, inner 6.0 mm), giving adequate routing flexibility within most mid-tower and full-tower chassis. The PWM-controlled pump operates between 800 and 2800 rpm, drawing 0.35 A at 12 V DC, and is managed independently from the fans via a splitter cable that provides three separate control channels. Two ARCTIC P12 Pro A-RGB fans come pre-installed on the radiator. Each uses a fluid dynamic bearing, spins between 600 and 3000 rpm (4-pin PWM), delivers up to 77 cfm of airflow, and generates 6.9 mmH₂O of static pressure — a figure suited to pushing air through dense radiator fins. Both fans feature 12 A-RGB Gen2 LEDs powered at 5 V DC via a 3-pin A-RGB plug with daisy-chain socket, compatible with most motherboard lighting headers and software such as SignalRGB. A distinguishing feature of the Pro variant is the integrated 60 mm VRM fan (400–2500 rpm, PWM), which directs airflow over the motherboard's voltage regulator modules — particularly useful in cases with limited natural airflow or during sustained overclocking sessions. Sockets supported are Intel LGA1851 and LGA1700, plus AMD AM5 and AM4. An included custom Intel Contact Frame reduces CPU lid deformation caused by Intel's Independent Loading Mechanism, while a 5 mm offset mount targets the thermal hotspot on AMD multi-die chiplet processors. The 0.8 g sachet of MX-6 thermal interface material is included in the box. Installation clearance requires at least 63 mm above the CPU socket; ARCTIC notes that oversized M.2 SSD coolers on some boards may affect fitment and offers a free M.2 cooler for affected configurations. The unit carries a 6-year manufacturer warranty. Operating ambient temperature range is 0–40 °C. Total assembled weight is 1665 g.
