Zalman Reserator5 Z24 Black CPU Liquid Cooler 240mm Radiator 2 x SF120 ARGB fan Processor All-in-one liquid cooler 12 cm

Zalman Reserator5 Z24 Black is an all-in-one CPU liquid cooler with a 240 mm radiator and two 120 mm SF120 ARGB fans. The cooler features a double-blade water pump for increased coolant flow (0.7–0.85 L/min), a pure copper cold plate, aluminum radiator, and braided nylon tubes. It supports 5V 3‑pin addressable RGB control via compatible motherboards and includes Zalman's ZM-STC8 thermal compound.

Advantages

The double-blade water pump design improves coolant circulation to enhance cooling performance while operating at lower speeds to reduce noise and extend pump life. A pure copper cold plate accelerates heat transfer from the CPU, and the aluminum radiator with optimized fins provides rapid heat dissipation. Dual-channel PWM control for fans and pump allows precise speed regulation for balanced cooling and acoustics. Durable braided nylon tubing and EBR-bearing SF120 fans increase reliability and longevity.

Suitable for

• Cooling high-performance desktop CPUs in gaming and workstation builds
• Systems requiring ARGB lighting synced via 5V 3‑pin motherboard headers
• Compact mid-tower and full-tower cases that fit a 240 mm radiator

How to use

Mount the 240 mm radiator into a case location that supports a dual 120 mm fan configuration (push, pull or push–pull) and secure the SF120 fans to the radiator. Install the pump block on the CPU socket, ensuring the pure copper cold plate contacts the CPU heat spreader. Connect the pump and fan 4‑pin PWM cables to appropriate motherboard headers for speed control, and attach the 3‑pin 5V ARGB cable to a compatible header to enable lighting control. Apply the included ZM-STC8 thermal compound between the CPU and cold plate if not pre-applied.

Recommendations

For stable operation, ensure your case supports a 240 mm radiator and that motherboard headers provide PWM control and a 5V 3‑pin ARGB connector. Maintain airflow by cleaning dust from radiator fins and fans periodically and verify secure tube routing to avoid kinks or contact with sharp edges.
