Dissipatore a liquido per CPU ZALMAN ALPHA2 V2 A24 240 mm — all-in-one sigillato, nero

ZALMAN ALPHA2 V2 A24 240 mm CPU Liquid Cooler — closed-loop AIO, black is a 240 mm closed-loop CPU liquid cooler designed to provide improved thermal performance over many air coolers. The unit integrates a dual-fan radiator and a compact pump-head assembly to circulate coolant and dissipate heat from modern desktop processors. Its black finish and low-profile pump are intended to fit standard mid-tower and full-tower cases that support a 240 mm radiator, offering a balance between cooling capacity and installation simplicity.

Advantages

The cooler combines a dual-fan 240 mm radiator with an integrated pump to reduce CPU temperatures more effectively than many stock or tower air coolers. It delivers quieter operation under moderate loads thanks to optimized fan speed range and hydraulic bearing design. The closed-loop design requires no maintenance from the user and simplifies installation compared with custom liquid systems. The compact pump-head minimizes clearance issues around memory modules and tall VRM heatsinks.

Suitable for

When it may not be suitable

This 240 mm closed-loop AIO may not be suitable for very small mini-ITX cases that lack mounting space for a 240 mm radiator. Systems requiring extreme overclocking headroom beyond typical consumer workloads might benefit from larger radiators (280 mm/360 mm) or custom loop solutions. Users who prefer passive cooling or who must avoid any liquid-cooled components for maintenance or reliability reasons should consider high-performance air coolers instead.

Key specifications

How to use

Install the radiator to a compatible case mount that supports a 240 mm radiator, using the supplied screws and mounting brackets. Mount the pump-head onto the CPU following the supplied thermal paste and mounting hardware, ensuring even contact with the CPU heat spreader. Connect the pump and fans to the motherboard headers or included splitters: pump to a dedicated pump or CPU_FAN/CPU_OPT header, and fans to PWM headers for automatic speed control. After installation, power on the system and verify fans and pump are spinning and that the BIOS or software reports pump/fan speeds. Monitor temperatures under idle and load to confirm correct operation.

What to consider before purchase

Recommendations

For best results, mount the radiator so airflow is unobstructed and fans intake or exhaust according to your system airflow plan. Use the motherboard fan control or supplied software to set a balanced fan curve that keeps temperatures in range while minimizing noise. Periodically check fan and pump connectors for secure seating and monitor system temperatures after BIOS updates or configuration changes.
