FAQs

What is the maximum rotational speed of these fans?

The maximum rotational speed for the be quiet! Light Wings LX 140mm PWM fans is 1800 RPM.

How many LEDs are on each fan?

Each fan features 16 individually addressable RGB LEDs.

What type of bearing do these fans use?

These fans utilize a Rifle bearing, known for its durability and quiet operation.

What is the warranty period for this product?

The be quiet! Light Wings LX fans come with a three-year warranty.

Can I control the fan speed and lighting separately?

Yes, the 4-pin PWM connector controls fan speed, while the 3-pin ARGB connector controls lighting. Both can be managed via motherboard software or controllers.

What is the airflow and noise level at maximum speed?

At maximum speed (1800 RPM), the airflow is 127.9 m³/h (75.3 cfm) and the noise level is up to 30.5 dB.

Do these fans come with screws?

Yes, the triple pack includes 12 screws for mounting the three fans.

Troubleshooting

Fan not spinning

Ensure the 4-pin PWM cable is securely connected to the motherboard fan header. Check if the motherboard BIOS/UEFI is set to allow fan operation or if the fan speed is set to 0 RPM in software.

ARGB lights not working or incorrect colors

Verify the 3-pin ARGB cable is correctly connected to a 5V ARGB header on the motherboard or controller. Ensure compatible RGB software is installed and configured correctly. Check that the fan is not set to 0 LEDs in software.

Fan making unusual noise

Check for any obstructions like cables hitting the fan blades. Ensure the fan is securely mounted and not vibrating against the case. If noise persists, it might indicate bearing wear, though MTBF is high.

PWM speed control not functioning

Confirm the 4-pin PWM connector is plugged into a PWM-capable header (often labeled CPU_FAN, SYS_FAN, or CHA_FAN with PWM). Check fan curves in BIOS/UEFI or software.

Pros and Cons

Pros

  • Excellent airflow for its size and noise level.
  • Vibrant and customizable ARGB lighting effects.
  • Quiet operation, especially at lower RPMs.
  • PWM support allows for precise speed control.
  • Durable construction with a 3-year warranty.
  • Attractive white design fits many builds.

Cons

  • Maximum fan speed can produce noticeable noise.
  • Requires compatible motherboard headers for full RGB and PWM functionality.
  • Cable length might be limiting in larger PC cases.

Setup, Compatibility & Care

Setup:

  1. Mounting: Secure the fans to your computer case or radiator using the included screws. Ensure correct airflow direction (usually indicated by arrows on the fan frame).
  2. Power Connection: Connect the 4-pin PWM connector to a CPU_FAN or SYS_FAN header on your motherboard for speed control.
  3. ARGB Connection: Connect the 3-pin ARGB connector to a compatible ARGB header on your motherboard or an ARGB controller.

Compatibility:

  • Motherboard Headers: Requires a 4-pin PWM fan header for speed control and a 3-pin 5V ARGB header for lighting synchronization. Check your motherboard specifications.
  • Case Mounts: Standard 140mm fan mounts are required. Fan dimensions are 140 x 140 x 25 mm.
  • Voltage: Operates on 12V for fans and 5V for ARGB.

Care:

  • Cleaning: Periodically clean dust from the fan blades and frame using compressed air or a soft brush. For stubborn dust, a slightly damp cloth can be used, ensuring the fan is disconnected from power and completely dry before re-operation.
  • Lubrication: The rifle bearing is sealed and does not require lubrication.
