The be quiet! LIGHT WINGS 120mm PWM high-speed is a single 120mm ARGB case fan for PC builders who want strong airflow and customizable lighting, with front-and-rear LEDs, motherboard-synced ARGB, and PWM speed control; its high-speed mode reaches 2,500 rpm and is rated at 31 dB(A).
Recommended For
- PC builders replacing or adding 120 mm fans on a liquid-cooling radiator who want higher-speed airflow and ARGB lighting; a professional review found the High-Speed version particularly well suited to radiator use.
- Builders using a restrictive radiator or CPU cooler who want a 120 mm fan with higher static pressure than the standard-speed Light Wings variant; the high-speed model is rated up to 2,500 rpm and 2.6 mmH₂O.
- RGB-focused PC builders who want lighting visible from both sides of the fan and motherboard-synchronized ARGB effects in a 120 mm build.
- Users who want one PWM fan for a radiator or cooler and are willing to set a motherboard fan curve to balance cooling with noise; community discussions describe using the high-speed model on radiators and running it below maximum speed.
Real-World Use Scenarios
- When fitting a 120 mm AIO or custom-loop radiator, use the fan to move air through the radiator fins; its high-speed design is intended for radiator use, with PWM control available to adjust speed as cooling demands change.
- When replacing or adding a fan on a compatible CPU heatsink, use the high-speed model where airflow through the heatsink is a priority; connect its PWM lead to control fan speed from the motherboard.
- When a case intake or exhaust position has a dust filter or other airflow restriction, this fan’s high-speed design can provide extra airflow headroom; set a motherboard fan curve to reduce speed when that extra cooling is not needed.
- For a showcase PC build, use the front and rear ARGB lighting to add visible color and sync it with compatible motherboard lighting; the fan itself still needs a separate PWM connection for speed control.

Reference Q&A
Q: Light Wings 120mm PWM High-Speed vs regular Light Wings 120mm PWM: which should I choose?
A: Choose the High-Speed model when you want more airflow and pressure headroom for a radiator or heatsink: it is rated for 2,500 RPM, 52.3 CFM, and 2.6 mmH₂O, compared with 1,700 RPM, 41.5 CFM, and 1.66 mmH₂O for the regular PWM model. Choose the regular model for a lower maximum speed and its case-fan-focused configuration. Both have PWM control and front-and-rear ARGB lighting.
Q: Should I get the Light Wings 120mm PWM High-Speed or the 140mm PWM High-Speed?
A: Choose this 120mm model if your case, radiator, or heatsink uses 120mm fan mounts. Choose the Light Wings 140mm PWM High-Speed if the mounting space supports 140mm fans and you want its rated 71.7 CFM airflow. Both models provide high-speed PWM control and front-and-rear ARGB lighting.
Q: Light Wings 120mm PWM High-Speed or Light Wings LX 120mm PWM: which fits an ARGB build better?
A: Choose the Light Wings 120mm PWM High-Speed for its front-and-rear illuminated rings and higher maximum speed of 2,500 RPM. Choose the Light Wings LX 120mm PWM for its illuminated hub and frosted fan blades, plus an ARGB cable with daisy-chain connectivity. Both are 120mm PWM fans with ARGB lighting.
Q: Can I control the fan speed and ARGB lighting through my motherboard?
A: Yes, if your motherboard has compatible headers: use a 4-pin PWM header for fan-speed control and a 5V 3-pin ARGB header for lighting synchronization. The fan’s product listing does not include a separate controller.
Q: Is this fan quiet enough for a noise-conscious PC?
A: At its maximum speed of 2,500 RPM, the fan is rated at 31 dB(A). PWM control lets a compatible motherboard reduce fan speed—and associated noise—when maximum cooling is not needed; actual noise depends on the speed setting and system setup.
Q: Can I use this fan on a radiator or heatsink?
A: Yes. Its 120 mm frame and stated 2.6 mm H₂O air pressure make it suitable for radiator and heatsink use, as well as case airflow. Check that your mounting space supports a 120 × 25 mm fan.
Q: Does it include a fan controller, and how many fans are in the package?
A: This listing is for one fan and specifies that no fan controller is included. Plan to connect it to a compatible motherboard header or another suitable controller you already have.
Q: Is the Light Wings 120mm High Speed a good choice for an AIO radiator?
A: It is a reasonable option if you want a 120mm ARGB fan for a radiator: a Reddit comparison points to the High Speed version’s higher static pressure than the standard Light Wings 120mm. It can reach 2,500rpm, so consider its noise at higher speeds when choosing it for a quiet build.
Q: Can I control the fan speed and ARGB lighting through my motherboard?
A: Yes, if your motherboard has a 4-pin PWM fan header and a compatible 3-pin 5V ARGB header. The single-fan model does not include a controller, so check your motherboard connections or obtain a compatible controller separately.
Q: Is the High Speed version quiet enough for a quiet PC build?
A: It may suit a quiet build when run below maximum speed, but it is not silent at full speed: the listed maximum is 2,500rpm and 31dB(A). Community reports about Light Wings noise vary, so noise-sensitive buyers should plan to tune the PWM fan curve and assess their tolerance for fan noise.
