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

The ARCTIC Liquid Freezer III 240mm ARGB in White (model ACFRE00150A) is a closed-loop all-in-one CPU liquid cooler designed for builders who demand quiet, reliable thermal management without sacrificing aesthetics. It ships ready to install: two ARCTIC P12 PWM PST A-RGB fans arrive pre-mounted on the radiator in a push configuration, and fan cables are routed neatly inside the hose jacket so only a single cable run reaches the motherboard header. At the heart of the cooler sits an in-house developed PWM-controlled pump operating between 800 and 2800 rpm, paired with a copper coldplate featuring micro-skived fins for maximised contact surface area. The 38 mm thick aluminium radiator measures 277 × 120 × 38 mm and offers an enlarged fin stack that extends the cooling surface and increases internal liquid volume, helping the system absorb and dissipate sustained power and temperature spikes more effectively over time. One standout feature is the integrated 60 mm VRM fan, which spins between 400 and 2500 rpm under PWM control. It directs airflow toward the motherboard's voltage regulation circuitry — an area that can run hot under heavy CPU loads — reducing thermal stress on components that tower coolers and basic AIOs leave unaddressed. Socket compatibility covers Intel LGA1700 (with included contact frame to reduce ILM-induced CPU deformation) and AMD AM5 and AM4. The AMD mount applies a 5 mm offset to align with the off-centre thermal hotspot common to AMD's multi-die Ryzen chiplet designs. ARCTIC also confirms compatibility with Intel's upcoming LGA1851 socket. Lighting is handled by 12 addressable RGB LEDs per fan using the standard 3-pin A-RGB connector — no proprietary adapters required. The daisy-chain design allows each LED to display an individual colour, and the system works with mainstream motherboard RGB software. MX-6 thermal compound is included in the box.
