be quiet! Light Wings LX 120mm PWM 3-Pack — Black

Quiet 25.5 dB(A)51.5 CFM16 ARGB LEDs3-Year Warranty

The be quiet! Light Wings LX 120mm PWM 3-Pack in black (article number BL121) is a set of three 120 mm PWM fans with an illuminated hub and frosted blades, designed for showcase builds that want strong ARGB lighting with be quiet!’s typical low noise.

Each fan has an ARGB cable with input and output connectors, so several Light Wings LX fans can be daisy-chained to one motherboard ARGB header or controller. Typically in stock with fast delivery across Cyprus.

Compatibility Note
Each fan uses a 4-pin PWM connector and a 5 V 3-pin ARGB connector (not compatible with 12 V 4-pin RGB headers). No ARGB hub or controller is included — connect to a motherboard 5 V ARGB header or a separate controller, and use a PWM splitter or fan hub if you do not have three free fan headers. Requires 120 mm fan mounts.

Frequently Asked Questions

Does the be quiet! Light Wings LX work with my motherboard lighting?
Yes, via a 5 V 3-pin ARGB header or a compatible ARGB controller. It does not support 12 V 4-pin RGB headers.
Is the Light Wings LX 120mm PWM 3-Pack suitable for a quiet PC?
Yes. At full speed it runs at 25.5 dB(A) with 51.5 CFM airflow, making it one of the quieter ARGB options in its size.
What is the difference between the standard and high-speed Light Wings LX 120mm?
The standard 120mm reaches 1,600 RPM, 51.5 CFM and 1.34 mmH₂O at 25.5 dB(A); the high-speed 120mm reaches 2,100 RPM, 61.8 CFM and 2.51 mmH₂O at 30.9 dB(A).
What do I need to know before buying BL121?
No ARGB hub is included, so plan a free 5 V ARGB header (fans daisy-chain) and three PWM headers or a splitter.
Singular Expert Insight
The standard Light Wings LX is the pick for quiet, bright ARGB case airflow; if the fans go on a radiator, the high-speed version adds pressure. Explore more sizes and colours in our case fans category.
