Be quiet! Silent Wings 4 PRO 140mm PWM
Be quiet! Silent Wings 4 PRO 140mm PWM
The Silent Wings Pro 4 140mm PWM fan delivers high performance, quiet operation and a wide range of uses. The newly designed blades, optimised for efficient airflow, combined with the minimal gap between the blades and the frame and a funnel-shaped outlet, provide effective air pressure during normal operation. The funnel-shaped outlet also improves airflow direction. The fan uses a 6-pole motor with a fluid dynamic bearing, which ensures smooth operation and a long lifespan. The speed switch lets you easily adapt the performance to your current cooling needs.
Key features of the Be quiet! Silent Wings 4 PRO 140mm PWM
- Blades optimised for efficient operation on both heatsinks and radiators
- Speed switch with three maximum speed levels (up to 2400RPM)
- Minimised gap between the blades and the frame and a funnel-shaped outlet ensure better air pressure
- Extremely quiet operation at normal speeds
- 6-pole motor and Fluid Dynamic Bearing ensure quiet and smooth operation
- Three mounting options – case, radiator and universal use
- All-black design with high-quality sleeved cable
- Long lifespan of up to 300000 hours
Optimised for high air pressure
The reduced distance between the blades and the fan frame increases air pressure, which is ideal for builds where efficient heat dissipation is a priority. The design of the Silent Wings 4 PRO 140mm PWM fan helps keep component temperatures lower, even under heavy load, and ensures stable and reliable system performance.
6-pole motor and fluid dynamic bearing
The 6-pole, three-phase motor reduces power consumption and vibrations, contributing to the quiet operation of the Silent Wings 4 PRO 140mm PWM fan, with a noise level of 36.8dB(A) at 100% speed. The fluid dynamic bearing guarantees a long lifespan of up to 300000 hours and helps maintain stable and quiet operation even under prolonged load.
Speed switch
The Silent Wings 4 PRO 140mm PWM fan is equipped with a switch that lets you choose between three performance levels – medium, high and ultra-high. This allows the user to easily set the mode according to their requirements – from an economical quiet mode for everyday use to maximum performance for intensive cooling.
Flexible mounting
The package includes three types of mounting corners for easy installation depending on the specific application. The anti-vibration corners are designed for mounting in a PC case and dampen transferred vibrations. The solid corners are optimised for radiators and provide a secure fit. The plastic mounts serve as a universal solution for common applications. A high-quality insulated PWM cable makes handling easier.
