14 cm PC Case Fan XILENCE XPF140.R.PWM, 140 mm, PWM control, up to 700 RPM

The Xilence XPF140.R.PWM 14 cm case fan provides quiet, efficient airflow for computer cases. With a 140 mm diameter and PWM speed control, it is designed to improve system cooling while keeping acoustic impact low. The fan uses a 4‑pin connector and is configured for case mounting to support general airflow management inside desktop PCs.

Advantages

The fan combines a large 140 mm impeller with PWM support to deliver flexible speed control and energy-efficient operation. Its maximum rotational speed of 700 RPM produces moderate airflow while maintaining a low noise level of around 30 dB. The included 4‑pin connector enables motherboard-based PWM control for automatic fan speed adjustment.

Suitable for

• General computer case ventilation
• Quiet home or office desktop PCs
• Systems needing PWM‑controlled fan speed

Key specifications

• Fan diameter: 140 mm
• Maximum rotational speed: 700 RPM
• Maximum airflow: 62.05 CFM
• Noise level at high speed: 30 dB
• PWM support: Yes (4‑pin connector)

How to use

Mount the fan to a standard 140 mm case fan location using appropriate screws, aligning airflow direction as required for intake or exhaust. Connect the 4‑pin connector to a motherboard header that supports PWM to allow automatic speed control, or to a compatible fan controller. Ensure the fan is secured and cables are routed to avoid contact with the blades.

Recommendations

Use the fan in cases with compatible 140 mm mounting points and enable PWM control in the motherboard BIOS or fan control software to balance cooling performance and noise. Periodically clean the fan blades and surrounding vents to maintain airflow efficiency.
