Montech RX120 PWM ventilátor počítačovej skrine 12 cm čierny 3 ks

Montech RX120 PWM Computer case Fan 12 cm Black 3 pc(s) is a 120 mm PWM-controlled cooling fan designed for case ventilation and general airflow management in desktop PCs. The fan features a 120 mm diameter rotor, a rifle bearing for reduced friction and longer service life compared with basic sleeve bearings, and a speed range that varies between approximately 800 RPM and 1600 RPM to match cooling demand. Its black finish integrates into a wide range of chassis interiors.

Advantages

The RX120 PWM delivers adjustable airflow through PWM control, allowing the motherboard or fan controller to vary speed based on temperature. The rifle bearing provides a balance of durability and quiet operation under normal loads. With a standard 120 mm form factor and neutral black colour, the fan is compatible with common case mounts and offers straightforward installation in single or multi-fan configurations.

Suitable for

• Improving case airflow in mid-tower and full-tower desktop PCs
• Replacing worn or noisy 120 mm case fans
• Setting up intake or exhaust fan arrays for balanced cooling
• Systems where PWM fan speed control is available

Key specifications

• Fan diameter: 120 mm
• Rotational speed range: 800–1600 RPM
• Bearing type: Rifle bearing
• Control type: PWM (pulse-width modulation) speed control
• Colour: Black
• Pack quantity: 3 fans

How to use

Mount the fan to an available 120 mm case fan spot using the supplied or standard mounting screws, aligning the airflow direction as required for intake or exhaust. Connect the fan's PWM cable to a motherboard fan header or compatible controller that supports PWM control to enable automatic speed regulation. Ensure cables are routed to avoid contact with the blades and that the fan is secured firmly to minimize vibration. Power the system and verify fan operation in BIOS or with software monitoring tools, adjusting fan curves if needed.

Recommendations

For best results, use these fans in systems with PWM-capable headers so speed can be adjusted dynamically; install them in coordinated intake and exhaust positions to maintain positive or neutral case pressure and periodically clean dust filters to preserve airflow and longevity.
