ARCTIC Liquid Freezer III Pro 420 A-RGB - AIO CPU Cooler, 3 x 140 mm Water Cooling, 38 mm Radiator, PWM Pump, VRM Fan, for AMD AM5/AM4, Intel LGA1851/1770 Contact Frame - Black
CONTACT FRAME FOR INTEL LGA1851 | LGA1700: Optimized contact pressure distribution for longer CPU life and better heat dissipation
ARCTIC's P14 PRO FAN: More power at any speed - more powerful and quieter than the P14, especially at low speeds. Higher maximum speed for optimal cooling performance under high load
NATIVE OFFSET MOUNTING FOR INTEL AND AMD: Shifting the cold plate center towards the CPU hotspot ensures more efficient heat transfer
INTEGRATED VRM FAN: PWM-controlled fan that lowers the temperature of the voltage converters and thus ensures reliable performance
INTEGRATED CABLE MANAGEMENT: The PWM cables of the radiator fans are integrated in the sheathing of the hoses so that only a single visible cable is connected to the motherboard

Product Information
Product description
P14 Pro Fan
Quieter and more powerful at low speeds, with more power reserves under load – for maximum cooling performance without compromise.
Intel Contact Frame
Optimized contact pressure distribution for longer CPU lifespan and more efficient heat transfer.
Easy Installation
Pre-installed, pre-wired fans and animated instructions for straightforward installation.
38 mm Premium Radiator
Improved heat dissipation and a larger fluid volume reduce heat buildup and allow for more efficient handling of temperature spikes.
Case Compatibility
Check the Dimensions
Please note that the Liquid Freezer requires at least 63 mm of free space for installation.
Decentralized Mounting
Better Cooling Performance for Intel and AMD CPUs
Moves the cold plate to the CPU hotspot, ensuring more efficient heat transfer.
Two Control Modes
Complete control or simple control
Control the pump, VRM, and radiator fans individually or via a PWM signal with an all-in-one cable.
60 mm Fan in CPU block
Active cooling in the socket area
Reduces the temperature of the voltage converters and ensures stable performance.
Integrated cable management
Fan cables integrated into the sleeving simplify installation and reduce the necessary cabling to a minimum.
Gen 2 Addressable RGB
Standardized 3-pin connector for high compatibility and control. Daisy chain and Gen 2 LEDs enable custom LED colors.
MX-6 thermal paste included
Apply MX-6 in a cross pattern – the water pump's cold plate will distribute the paste evenly.
Premium Tubing
Reinforced EPDM hose with braided braid for maximum durability.
