Light Wings 140mm PWM High Speed - Black - be quiet!
IMPRESSIVE LIGHTING Lots of illumination possibilities Light Wings 140mm PWM high-speed offe...IMPRESSIVE LIGHTING Lots of illumination possibilities Light Wings 140mm PWM high-speed offers ARGB lighting at the front and rear. The subtly lit ring at the back combined with the bright one at the front make for a magnificent appearance from every angle. 20 ARGB LEDs give you many opportunities to individualize your PC build. FOR RADIATORS AND HEATSINKS Fan blades optimized for high pressure With a remarkably high air pressure of up to 2.3mm/H2O, Light Wings 140mm PWM high-speed is the best choice for water-cooled and air-cooled systems alike. The 9 airflow-optimized fan blades provide enough air pressure to make this fan perfect, even in demanding configurations. QUIET OPERATION Acclaimed be quiet! low noise level A highly optimized impeller achieves the silent operation be quiet! is famous for. With a noise level of 31dB(A) at maximum fan speed, it proves that instead of being a replacement the lighting is an addon to silent and very powerful operation. All features combine to make Light Wings 140mm PWM high-speed the fan of choice for silent show cases and gaming systems alike. VARIABLE FAN SPEED FUNCTION Adjusts the fan speed and associated noise level Pulse Width Modulation (PWM) allows compatible 4-pin controllers, including those built into many motherboards, to intelligently vary the speed and thus the noise level of the fan. With PWM the system can ramp up the cooling when its needed, or operate in maximum quiet mode when its not.
The be quiet! Light Wings 140mm PWM high-speed fan is designed for PC enthusiasts seeking a blend of impressive ARGB lighting, powerful cooling performance, and quiet operation. Ideal for custom builds that prioritize both aesthetics and thermal management, this fan offers significant illumination possibilities and high air pressure. Its primary caveat is the 'high-speed' designation, which means it operates at a higher RPM and potentially higher noise level when maxed out compared to non-high-speed models, though still within be quiet!'s acclaimed low noise levels. Key features include dual ARGB lighting zones, optimized fan blades for high static pressure, and PWM support for intelligent speed control.

Extended Product Information
FAQs
What is the maximum noise level of this fan?
At its maximum rotational speed of 2200 RPM, the fan produces a noise level of 31dB(A).
Can I control the ARGB lighting without a motherboard header?
Yes, if your motherboard does not have a 3-pin 5V ARGB header, you can use a compatible external ARGB controller to manage the lighting effects.
What type of bearing does the Light Wings 140mm PWM high-speed fan use?
This fan utilizes a Rifle bearing, known for its durability and quiet operation over a long lifespan.
Is this fan suitable for a radiator?
Yes, with a high static pressure of 2.3mm/H2O, it is very well-suited for use on radiators and dense heatsinks.
What is the airflow and air pressure rating?
The fan provides a maximum airflow of 121.82 m³/h (71.7 cfm) and a maximum air pressure of 2.3 mmH2O.
How do I connect the ARGB lighting?
Connect the 3-pin ARGB cable to a 3-pin 5V ARGB header on your motherboard or a compatible ARGB controller. Ensure correct pin alignment.
What is the warranty period for this fan?
Please refer to the official be quiet! website or product packaging for specific warranty information, as it can vary by region and retailer.
Troubleshooting
Fan does not spin
Ensure the 4-pin PWM fan cable is securely connected to a working fan header. Verify that the motherboard or fan controller is providing power. Check if the fan speed is set to 0 RPM in BIOS or software settings.
ARGB lighting not working
Confirm the 3-pin 5V ARGB cable is correctly plugged into a compatible ARGB header on the motherboard or controller. Ensure ARGB lighting is enabled in your motherboard's BIOS or control software. Check for any physical damage to the ARGB cable.
Fan is unusually noisy
Verify fan speed settings. If running at maximum RPM, noise is expected. Check for any obstructions (cables, components) that might be rattling against the fan blades or frame. Ensure the fan is securely mounted and not vibrating against the case.
PWM speed control is not functioning
Ensure the fan is connected to a 4-pin PWM header. Check your motherboard's BIOS settings to confirm PWM mode is enabled for the connected header. Update motherboard BIOS and chipset drivers if necessary.
Pros and Cons
Pros
Vibrant and customizable ARGB lighting with dual illumination zones.
Excellent air pressure (2.3mm/H2O) suitable for radiators and dense heatsinks.
Quiet operation at lower speeds, adhering to be quiet!'s reputation.
PWM support for dynamic and intelligent fan speed control.
Durable construction with a rifle bearing for longevity.
Cons
Noise level can reach 31dB(A) at maximum speed, which might be noticeable in very quiet environments.
High-speed operation might be overkill for systems that do not require extreme cooling.
ARGB lighting requires a compatible motherboard or controller.
Setup, Compatibility & Care
Setup:
Mounting: Secure the fan to your chosen location (case, radiator, heatsink) using the included screws. Ensure the airflow direction arrow on the fan frame points towards the intended airflow path.
Connection: Connect the 4-pin PWM fan cable to a compatible fan header on your motherboard or a dedicated fan controller. Connect the ARGB cable to a 3-pin 5V ARGB header on your motherboard or controller.
Power: The fan operates on a standard 12V system, with a voltage range of 5 - 13.2V.
Compatibility:
Motherboard Headers: Requires a 4-pin PWM fan header for fan speed control and a 3-pin 5V ARGB header for lighting synchronization. Ensure your motherboard or controller supports these standards.
Case/Radiator Mounts: Standard 140mm mounting points.
Care:
Cleaning: Periodically dust the fan blades and frame using compressed air or a soft, dry brush. For stubborn dust, a slightly damp (not wet) cloth can be used on the blades, ensuring no moisture enters the motor or bearing.
Lubrication: The rifle bearing is designed for long-term, maintenance-free operation. Do not attempt to lubricate.
Storage: If storing the fan, keep it in a dry environment away from extreme temperatures.
