Thermaltake AW420 Workstation AIO Liquid Cooler, Nickel-Plated Copper Water Block, Air Flow 119.6CFM (one fan), Air Pressure 3.57 mm-H2O (one fan), PWM 500~2000 R.P.M, Supports Intel LGA4677 & AMD sTR5 / SP6 Sockets, Black | CL-W445-PL14BL-A

Designed for enthusiasts who refuse to compromise on thermals, the Thermaltake AW420 (CL-W445-PL14BL-A) is a top-tier cooling solution that utilizes the sheer scale of a 420mm radiator. This AIO is purpose-built for the latest generation of power-hungry CPUs, providing significantly more cooling surface area than standard 360mm units. Whether you are pushing an Intel Core i9 or an AMD Ryzen 9 to its limits, the AW420 ensures your system stays cool under the most extreme workloads.

Key Features
Massive 420mm Radiator: The extra-large aluminum radiator maximizes heat exchange, allowing for lower fan speeds and quieter operation while maintaining elite cooling performance.

Triple 140mm ARGB Fans: Equipped with three high-performance 140mm fans optimized for static pressure. These fans drive massive amounts of air through the dense radiator fins while offering customizable RGB effects.

High-Efficiency Copper Cold Plate: The large, high-purity copper base plate ensures rapid heat transfer from the CPU IHS to the cooling loop, covering even the largest modern processor heat spreaders.

Universal Socket Compatibility: Fully compatible with the latest sockets, including Intel LGA 1700/1851 and AMD AM5/AM4, ensuring a future-proof investment for your build.

Performance / Technology
The AW420 utilizes a high-reliability pump that maintains a consistent flow of coolant with minimal vibration. The reinforced sleeved tubing prevents evaporation and ensures long-term durability, even in high-temperature environments. By utilizing PWM (Pulse Width Modulation) control for both the pump and fans, the system can dynamically adjust its cooling intensity based on real-time CPU temperatures, providing a silent experience during light tasks and maximum power during gaming.

Design & Aesthetics
Synchronized ARGB Lighting: The pump head and fans feature addressable LEDs that are compatible with major motherboard software, including ASUS Aura Sync, GIGABYTE RGB Fusion, MSI Mystic Light, and ASRock Polychrome.

Clean Cable Management: Designed with simplified wiring to keep your interior looking professional and clutter-free.

Sleek Mirror-Finish Pump: The pump cover features a modern aesthetic that complements any high-end PC build, serving as the visual centerpiece of your chassis.

Why This Product Stands Out
The Thermaltake AW420 stands out because it targets the "sweet spot" of extreme cooling. Most cases that support 420mm radiators are flagship-class, and this cooler is designed to match that tier of hardware. While smaller AIOs might struggle with the heat spikes of modern "AI PCs" and high-core-count processors, the AW420 provides the thermal headroom necessary for true stability and longevity.
