Alphacool fan Apex Stealth Metall 120x120x25 mm 2600 rpm (model 13778)

Alphacool Apex Stealth Metall is a 120 x 120 x 25 mm cooling fan designed for use in PC chassis, radiators and liquid-cooling assemblies. With a maximum speed of 2600 rpm, the fan delivers focused airflow to improve heat dissipation for CPU, GPU and system components. The metal frame and reinforced construction increase structural stability, reduce vibration transfer and extend service life compared with typical plastic-frame fans. The fan is suitable for both single-fan installations and push/pull radiator configurations where reliable, directional airflow is required.

Advantages

The metal frame construction provides improved durability and reduced resonance when mounted to cases or radiators. A high maximum rotational speed enables strong airflow and static pressure for radiator use while maintaining a compact 120 mm footprint. The fan's design balances cooling performance and noise control, making it applicable for performance-oriented systems and quieter builds alike. Compatibility with standard 120 mm mounting points simplifies integration into existing systems.

Suitable for

• Case ventilation in gaming and workstation PCs
• Radiator cooling in liquid-cooling loops (single or push/pull setups)
• Upgrading stock chassis fans to improve airflow and thermal performance
• Systems requiring a robust fan with lower vibration transmission

Key specifications

• Size: 120 x 120 x 25 mm
• Maximum speed: 2600 RPM
• Frame material: metal (reinforced frame for reduced vibration)
• Designed airflow: focused directional airflow suitable for radiators
• Mounting: standard 120 mm mounting pattern

How to use

Install the fan in a standard 120 mm mounting location in the case or attach it to a radiator using appropriate screws. Observe correct airflow orientation for intake or exhaust depending on cooling goals; for radiators, position fans to create either push, pull or push/pull airflow as required. Connect the fan to the system fan header or a compatible controller, and set fan curves in BIOS or a software fan controller to balance cooling performance and acoustic levels. Secure the fan firmly to the chassis or radiator to minimize vibration transfer.

Recommendations

For radiator applications, consider using matched fans in push/pull configuration to maximize heat transfer. Adjust fan speed profiles to ramp up under load and reduce noise during idle periods. Ensure airflow direction and chassis airflow balance are planned to avoid creating hotspots inside the case.
