120mm fan Alphacool Apex Stealth Metall Aurora — 2600 RPM, metal frame

Alphacool Apex Stealth Metall Aurora is a 120mm cooling fan featuring a robust metal frame and a maximum rotational speed of 2600 RPM. Designed for PC cooling and radiator use, this fan delivers focused airflow for case ventilation, CPU and GPU radiator setups, and custom liquid-cooling loops. The metal construction increases structural stability and longevity compared with typical plastic-framed fans, while the blade geometry and motor tuning are optimized to balance airflow and acoustic output for continuous desktop operation.

Advantages

The metal frame provides improved durability and reduced vibration transfer to the chassis, making the fan suitable for long-term, continuous use. With a top speed of 2600 RPM the unit can generate higher static pressure than many low-speed alternatives, which is beneficial when mounted on radiators or dense filter arrays. The design supports steady airflow for case circulation and radiator cooling with consistent performance over extended periods.

Suitable for

• Case ventilation for desktop systems
• Mounting on CPU and GPU radiators in air- or liquid-cooled builds
• Custom liquid-cooling loops requiring durable fans
• Environments where reduced vibration and structural rigidity are needed

Key specifications

• Size: 120 mm fan
• Maximum speed: 2600 RPM
• Frame material: metal
• Intended use: case ventilation, radiator mounting
• Form factor: standard 120 mm mounting holes

How to use

Install the fan using the standard 120 mm mounting holes on your case or radiator bracket, ensuring correct airflow orientation for intake or exhaust depending on system layout. Connect the fan to an appropriate fan header or controller that supports the fan's voltage and control method; use PWM control if available to adjust speed based on temperature. Secure mounting and firm electrical connections are recommended before operating the system. Periodic cleaning of dust from blades and radiator fins will help maintain optimal cooling performance.

Recommendations

For radiator applications, position the fan to push air through the radiator fins with consistent RPM control to balance cooling and noise. Use anti-vibration mounts or rubber washers if necessary to further reduce chassis-transmitted vibration. Monitor temperatures after installation to confirm expected thermal improvements and adjust fan curves in software or hardware controllers to optimize performance.
