DeepCool CASTLE EX A-RGB AIO Liquid CPU Cooler — White | 240mm / 360mm | Intel LGA1700 / AMD AM5

The DeepCool CASTLE EX A-RGB WH is built for white-themed gaming PC builds, content creators, and enthusiast system builders on Intel or AMD platforms who want effective and low-noise AIO liquid cooling with iconic infinity mirror ARGB aesthetics in a clean, premium all-white finish. The 240mm variant suits mid-range CPU builds and cases with limited radiator space, while the 360mm variant delivers greater thermal headroom for flagship and high-TDP CPUs under sustained workloads. Both are well-suited for all-white showcase builds with ARGB motherboard sync support via ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, and ASRock Polychrome.

The CASTLE EX A-RGB WH features DeepCool's iconic infinity mirror pump head design — an enlarged mirror chip with the refreshed DeepCool logo — creating a striking visual centrepiece that radiates addressable RGB light in multiple layered reflections, all housed in a premium white enclosure that complements white-themed build aesthetics. Both variants use DeepCool CF120 ARGB PWM fans with 12 individually addressable RGB LED nodes per fan, delivering vibrant, software-synced lighting alongside strong 69.34 CFM max airflow and 2.42 mmAq static pressure at 500–1800 RPM for effective radiator cooling at low noise levels of ≤30 dB(A). The dual-chamber pump design features an optimized internal flow route for better heat exchange and higher coolant flow rate, powered by a stronger 3-phase motor that operates at a quiet 17.8 dB(A). The enlarged copper cold plate features 25% more skived fins compared to standard designs, dramatically increasing heat dissipation surface area for more efficient thermal transfer at the CPU IHS. DeepCool's patented Anti-Leak Technology regulates internal pressure balance across the sealed loop, significantly improving long-term operational safety and minimising leakage risk. The swappable custom logo design lets users twist off the pump face to reorient the logo for clean presentation regardless of radiator mounting angle. A-RGB lighting syncs via 5V 3-pin ARGB motherboard header or the included A-RGB controller for motherboards without native ARGB support.
