FAQs

What is the maximum fan speed and noise level?

The maximum fan speed is 2400 RPM. At this ultra-high speed, the noise level can reach up to 36.8 dB(A). At mid-speed, it is virtually inaudible.

How do I change the fan speed?

Use the integrated speed switch located on the fan's frame. Slide it to select between medium, high, and ultra-high-speed settings.

What does PWM support mean?

PWM (Pulse-Width Modulation) support allows the fan's speed to be automatically adjusted by the motherboard based on system temperature. It provides finer control over cooling and acoustics.

What is the lifespan of the Fluid-Dynamic Bearing (FDB)?

The FDB is rated for an impressive lifespan of up to 300,000 hours, ensuring long-term reliability and quiet operation.

Can I use this fan on a 3-pin header?

Yes, you can connect it to a 3-pin header, but it will run at full speed continuously and speed control via voltage will not be possible. For full PWM functionality, a 4-pin header is required.

What mounting options are included?

The fan comes with pre-installed radiator corners, anti-vibration mounts for case installation, and additional plastic mountings for versatile use.

What is the warranty period?

The SILENT WINGS PRO 4 140mm PWM White fan comes with a 5-year manufacturer warranty.

Troubleshooting

Fan does not spin

Verify the 4-pin PWM connector is securely plugged into the motherboard header. Check that the speed switch is not set to the lowest possible setting if your motherboard's BIOS has fan control limitations. Ensure the fan header is receiving power from the PSU.

Fan is noisy at medium or low speed

Confirm the fan is securely mounted to prevent vibrations. Ensure no cables are touching the fan blades. Check the speed switch setting; the 'virtually inaudible' claim is primarily for mid-speed operation.

Cannot control fan speed via software

Ensure the fan is connected to a PWM header on the motherboard and that PWM mode is enabled in your BIOS settings. Some motherboards may have specific software for fan control.

Pros and Cons

Pros

  • Exceptional cooling performance and high air pressure.
  • Extremely quiet operation, especially at lower speeds.
  • Versatile speed control for different use cases.
  • Durable Fluid-Dynamic Bearing for long lifespan.
  • Multiple mounting solutions for flexible installation.
  • Premium build quality and attractive white design.

Cons

  • Higher price point than many other fans.
  • Ultra-high speed can be audible, though still efficient.
  • 140mm size may not fit all standard 120mm fan mounts without adapters.

Setup, Compatibility & Care

Setup:

  1. Choose Mounting: Select the appropriate mounting system for your needs: radiator corners for radiators, anti-vibration mounts for case mounting, or standard plastic mountings.
  2. Attach Fan: Secure the fan to your chosen mounting point using the provided screws.
  3. Connect to Motherboard: Plug the 4-pin PWM connector into an available CPU_FAN or CHA_FAN header on your motherboard. Ensure the connector is oriented correctly.
  4. Speed Switch: Set the desired speed profile using the integrated speed switch.

Compatibility:

  • Form Factor: Standard 140mm fan size. Ensure your case, radiator, or CPU cooler has compatible mounting points.
  • Motherboard Header: Requires a 4-pin PWM fan header for full speed control. Can be used with 3-pin headers, but speed will be fixed at maximum.
  • Voltage: Operates on 12V, with a voltage range of 7V to 13.2V.

Care:

  • Cleaning: Periodically dust the fan blades and frame using compressed air or a soft, dry brush. For stubborn dust, use a slightly damp cloth, ensuring the fan is disconnected and dry before reconnecting.
  • Bearing: The Fluid-Dynamic Bearing is sealed and requires no user maintenance.
