Ventoinha Alphacool Apex Stealth Metal 12 cm Preto 400-3000 U/min 30-49.9 dB

The Alphacool Apex Stealth Metall 12 cm fan is a compact cooling solution for computer systems and enclosures requiring high airflow in a small form factor. With a diameter of 120 mm and a wide rotational speed range from 400 to 3000 RPM, this fan balances quiet low-speed operation and powerful high-speed performance. The design incorporates a Hydro Dynamic Bearing to prolong service life and maintain stable operation across varied workloads.

Advantages

The fan delivers a maximum airflow of 116.89 CFM while maintaining controlled noise levels between 30 dB at the lowest setting and 49.9 dB at the highest setting, allowing users to choose between quiet cooling and maximum ventilation. The Hydro Dynamic Bearing reduces friction and wear for improved longevity and consistent performance. Its metal-styled housing and compact 120 mm form factor enable compatibility with standard fan mounts and contribute to structural durability under continuous use.

Suitable for

• PC cases requiring high airflow for CPU or GPU cooling
• Radiator and liquid-cooling loops where strong push/pull airflow is needed
• Small server enclosures and workstation cabinets with 120 mm fan mounts
• Replacement or upgrade of stock 120 mm case fans for better performance

Key specifications

• Fan diameter: 120 mm
• Speed range: 400–3000 RPM
• Maximum airflow: 116.89 CFM
• Noise level: approx. 30 dB (low) to 49.9 dB (high)
• Bearing type: Hydro Dynamic Bearing
• Color/finish: black metal-style housing

How to use

Install the 120 mm fan into a compatible fan mount or radiator with the correct orientation for intake or exhaust airflow. Secure the fan using the supplied mounting screws or vibration-damping mounts if available, and connect to the motherboard fan header or a compatible fan controller that supports the fan's voltage and speed range. Adjust fan speed through BIOS, operating system software, or a dedicated fan controller to select between quiet operation at lower RPMs or maximum airflow near 3000 RPM based on thermal requirements.

Recommendations

For balanced system cooling and acoustics, configure fan curves to run the Alphacool Apex Stealth Metall at lower RPMs during idle and moderate loads, increasing speed only when CPU or GPU temperatures rise. Ensure adequate airflow paths in the case and clean fan blades periodically to maintain peak performance and reduce noise over time.
