DEEPCOOL CASTLE 240EX 240mm ARGB CPU Liquid Cooler (Black)

The Deepcool Castle 240EX is a 240mm all-in-one liquid CPU cooler designed for builders who want reliable thermal performance alongside eye-catching addressable RGB lighting. At the heart of the cooler is the signature Castle EX infinity mirror pump head, which houses an enlarged mirror panel displaying the Deepcool logo and delivers a layered lighting effect when connected to a 5V ARGB header on a compatible motherboard. The pump operates at 2550 RPM (±10%) with a rated noise level of just 17.8 dB(A), drawing only 2.4 W at 12 VDC — keeping the system quiet under typical workloads. Two Deepcool CF120 ARGB fans are included, each measuring 120×120×25 mm and spinning between 500 and 1800 RPM (±10%) via 4-pin PWM control. At full speed they deliver up to 69.34 CFM of airflow at 2.42 mmAq static pressure, with noise rated at ≤30 dB(A). The fans use hydro bearings and consume 2.04 W each at 12 VDC, making them efficient across a wide speed range. The aluminum radiator measures 282×120×27 mm and is connected to the pump block via 380 mm tubes. The copper cold plate features 25% more skived fins compared to the previous generation, increasing surface area for improved heat transfer across the CPU integrated heat spreader — with stated support for TR4 sockets. The dual-chamber pump is designed with an optimised internal flow route to improve heat exchange efficiency. Addressable RGB illumination runs at 5 VDC through a standard 3-pin (+5V-D-G) header, compatible with major motherboard lighting ecosystems including ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion, and ASRock Polychrome. The pump LED draws 2.25 W and the two fan LEDs draw a combined 4.4 W. The pump face is twist-off for easy orientation adjustment and supports swappable custom logo inserts. DeepCool’s Anti-Leak Technology — developed after three years of R&D — regulates internal pressure balance to reduce the risk of coolant leakage over the product lifespan.
