ARCTIC Liquid Freezer III Pro 420 A-RGB AIO CPU Cooler 3x140mm PWM Fan Integrated VRM Fan AMD AM5/AM4 Intel LGA1851/1700
Available in stock (27)
Key Features
- 420mm Triple 140mm A-RGB Radiator — Massive 420mm radiator with three P14 Pro PWM A-RGB fans delivers class-leading airflow and static pressure, handling the most thermally demanding processors without throttling.
- Integrated VRM Fan — Built-in 40mm fan on the pump head directs airflow toward motherboard VRM and power delivery components, maintaining system stability and prolonging component life under sustained full-load operation.
- 38mm Thick Radiator — Extra-thick radiator holds significantly more coolant than standard 25mm or 30mm designs, providing a larger thermal buffer that smooths out temperature spikes during overclocking and extended heavy workloads.
- Offset Pump Head with Intel Contact Frame — Offset cold plate targets the primary CPU heat-generating die directly; bundled Intel contact frame corrects socket flex on LGA1700 and LGA1851 for consistent, even mounting pressure.
- PWM Pump Control up to 2800 RPM — Pump speed adjusts automatically with thermal load, delivering maximum flow when needed while staying near-silent during light tasks.
- Pre-applied MX-6 Thermal Paste — High-performance MX-6 compound comes pre-applied to the cold plate for immediate installation with no extra preparation required.
- Integrated Cable Management in Tubing — Fan and pump cables route inside the tubing sleeve, eliminating cable clutter and keeping builds clean regardless of case layout.
- 6-Year Manufacturer Warranty — ARCTIC backs the Liquid Freezer III Pro 420 with an industry-leading 6-year warranty, a strong indicator of long-term build quality and reliability.
The ARCTIC Liquid Freezer III Pro 420 A-RGB is ARCTIC’s largest and most capable all-in-one CPU liquid cooler, designed for builders who refuse to compromise on thermal performance. The 420mm radiator accommodates three 140mm P14 Pro PWM A-RGB fans operating between 200 and 1700 RPM, generating the combined airflow and static pressure needed to keep flagship processors — including Intel Core i9-14900K, i9-13900KS, and AMD Ryzen 9 7950X3D — running at full boost clocks through the most demanding workloads. The 38mm radiator thickness stores considerably more coolant than standard AIO designs, acting as a larger thermal reservoir that absorbs and dissipates heat spikes during all-core overclocking, extended rendering sessions, and multi-hour gaming marathons. A-RGB lighting on all three fans and the pump head syncs natively with ASUS Aura Sync, MSI Mystic Light, and Gigabyte RGB Fusion via the standard 3-pin 5V header, enabling a cohesive lighting setup across an entire system without additional controllers or hubs.
Ideal For
- Flagship CPU Builds — Provides the thermal headroom required to run Intel Core i9 and AMD Ryzen 9 processors at sustained all-core boost clocks without throttling or thermal shutdown.
- Extreme Overclocking — The 420mm radiator and integrated VRM cooling give serious overclockers the sustained performance and motherboard component protection needed for aggressive frequency and voltage tuning.
- Content Creation and Rendering Workstations — Keeps high-core-count CPUs cool through hours of video encoding, 3D rendering, simulation, and compilation without performance degradation.
- Enthusiast RGB Builds — Three A-RGB fans and a lit pump head create a dramatic, synchronized lighting effect that integrates seamlessly with all major motherboard lighting ecosystems.
- Silent High-Performance Setups — PWM fan and pump control keeps the system near-silent during light use while automatically ramping up only when thermal demand requires it.
