Koeler Zalman CNPS10X OptimaII

The Cooler Zalman CNPS10X OptimaII is a 120 mm CPU cooler with a white LED fan and a hydraulic bearing designed for quiet, reliable operation. With a rotational speed range of 800–1500 RPM and a thermal design power (TDP) of 150 W, it provides efficient heat dissipation in a compact housing measuring 132 mm × 85 mm × 160 mm. The unit supports a wide range of Intel and AMD sockets and has a clean white finish for modern system builds.

Advantages

The hydraulic bearing fan reduces operational noise while maintaining consistent airflow across the radiator fins. The 120 mm fan delivers balanced cooling performance at speeds between 800 and 1500 RPM. Compatibility with many Intel and AMD sockets ensures broad platform support. The white colour and integrated white LED lighting offer a neutral aesthetic that fits different case themes.

Suitable for

• Silent or low-noise PC builds
• Compact mid-tower and small form-factor systems
• Mainstream gaming and productivity systems with up to 150 W TDP
• Systems where a white aesthetic is desired

How to use

Mount the Zalman CNPS10X OptimaII on a compatible CPU socket following the motherboard and cooler mounting instructions. Apply an appropriate amount of thermal paste to the CPU heatspreader, align the cooler with the mounting points, and secure it evenly to ensure good contact. Connect the fan cable to the CPU_FAN or system fan header and configure fan control in BIOS or your operating system for desired noise/performance balance.

Recommendations

For optimal results, use quality thermal paste and periodically clean dust from the heatsink and fan. If you prioritise lower noise, configure a fan curve that keeps RPMs closer to the lower range during light workloads while allowing higher speeds under sustained load.
