Ventoinha Montech AX140 PWM 14 cm preta 540-1760 RPM

The Montech AX140 PWM 14 cm case fan combines a modern aesthetic with functional cooling. It features a hexagonal RGB ring with 24 integrated LEDs and supports 5V 3-pin motherboard connectors for software control. Designed for compatibility as a case, radiator or radiator fan, the AX140 PWM delivers stable airflow and enhanced heat dissipation for high-end builds while remaining compact in a black finish.

Advantages

The AX140 PWM offers customizable RGB lighting, a wide speed range (540–1760 RPM) and a durable rifle bearing rated for up to 80,000 hours. Its nine-blade design and optimized bending angles stabilize airflow to improve cooling efficiency and reduce noise. Rounded anti-vibration pads minimize vibration and resonance for quieter operation.

Suitable for

• Case cooling in desktop PCs
• Radiator fan for liquid cooling loops
• High-performance and gaming builds
• Systems requiring software-controlled RGB lighting (5V 3-pin)

How to use

Install the AX140 PWM in your case or on a radiator using the appropriate mounting screws. Connect the fan power cable to a PWM-capable 4-pin fan header on the motherboard for automatic speed control, and connect the 5V 3-pin RGB header to a compatible motherboard RGB connector to control lighting through software. Ensure airflow direction aligns with your case cooling plan and secure anti-vibration pads contact surfaces to reduce resonance.

Recommendations

For optimal balance between cooling and noise, use PWM control to allow the motherboard to adjust fan speed according to temperature. When using the lighting, confirm your motherboard supports 5V 3-pin RGB and configure profiles in the manufacturer's RGB software. Periodically clean the fan blades to maintain airflow and prolong bearing life.
