Ventilátor Razer Kunai Chroma 14 cm čierny 500-1500 ot/min

The Razer Kunai Chroma 14 cm Black 500-1500 RPM is a 140 mm computer case fan engineered to provide controlled airflow for desktop PCs. Designed with a black finish to integrate into gaming rigs and professional builds, the fan delivers variable rotational speeds between 500 and 1500 RPM to balance cooling performance and acoustic profile. Its compact weight and standard 140 mm diameter make it compatible with common fan mounts and chassis layouts.

Advantages

The fan offers a broad RPM range that enables quieter operation at lower loads and increased airflow when demand rises. The 140 mm blade size produces effective static pressure and air movement compared with smaller fans, supporting more efficient heat dissipation from components and radiators. The neutral black colour and low-profile design allow flexible placement in cases without drawing visual attention.

Suitable for

• General case ventilation for gaming and workstation PCs
• Improving airflow for air-cooled CPU and GPU setups
• Mounting on radiators in liquid cooling loops compatible with 140 mm fans
• Replacing worn or noisy 140 mm case fans

Key specifications

• Fan diameter: 140 mm
• Rotational speed: 500–1500 RPM
• Colour: black
• Weight: 0.207 kg
• Form factor: standard 140 mm case fan

How to use

Install the fan into a compatible 140 mm mounting location in your PC case or on a radiator using the provided screw mounting points. Connect the fan to an available motherboard fan header or a compatible fan controller to enable speed regulation across the 500–1500 RPM range. Ensure correct airflow orientation by aligning the intake and exhaust directions with your case airflow plan, and secure cables to avoid interference with moving blades.

Recommendations

For optimal results, configure the fan curve in BIOS or a fan-control utility to keep system temperatures within acceptable limits while minimizing noise. When used on radiators, verify that the fan spacing and push/pull arrangement match the radiator specifications. Periodically clean dust from the blades and grille to maintain airflow efficiency and prolong service life.
