Pros & Cons

Pros

✓ 18 LEDs on front and rear light the fan from both sides of a glass panel
✓ Rated 31dB(A) at its full 2,500rpm ceiling
✓ Rifle bearing rated for 60,000 hours of operating life
✓ 4-pin PWM lets the motherboard drop speed and noise at idle

Cons

✗ 31dB(A) at the full 2,500rpm ceiling is audible in a quiet room
✗ Ships as a single fan, so a 360mm radiator means buying three
✗ ARGB control needs a motherboard addressable header; no inline controller
✗ Listing contradicts itself on blade count: seven in one spec line, nine in another

Manufacturer description

The be quiet! Light Wings 120mm PWM High Speed is for builders who want ARGB lighting without giving up the quiet running the brand is known for. Eighteen LEDs illuminate both the front and the rear of the frame, so the glow reads from either side of a tempered-glass panel, and the lighting syncs with your motherboard's ARGB adjustments rather than requiring a separate controller in the loop. The silence-optimized blade design targets pressure rather than raw open-air airflow, which is why be quiet! positions this High Speed variant for radiators and heatsinks specifically. At its 2,500rpm…

Frequently Asked Questions

Will the Light Wings 120mm fit a 240mm or 360mm radiator?

It is a standard 120mm fan sized for 120mm mounting points, so it fits 120mm, 240mm, and 360mm radiator mounts. The BL073 is a single fan, so a 240mm mount needs two and a 360mm mount needs three.

How loud is the be quiet! Light Wings 120mm High Speed?

be quiet! rates it at 31dB(A) at its full 2,500rpm. Because it uses a 4-pin PWM connector, your motherboard can lower the speed and the noise whenever the system is not under load.

Do I need a separate ARGB controller for the lighting?

No. The 18 LEDs are designed to sync with your motherboard's ARGB adjustments, so control runs through the board's addressable header. If your board lacks that header, you would need a third-party controller.

How long is the fan rated to last?

The long-life rifle bearing carries a rated operating lifetime of 60,000 hours. Check the product listing for current warranty terms, which be quiet! sets separately from the bearing rating.

Is this the standard Light Wings or the High Speed version?

This is the High Speed variant, model BL073, running up to 2,500rpm and aimed at radiators and heatsinks where pressure matters.
