be quiet! Pure Wings 3 120mm PWM Reverse 3-Pack (Black)

3 x 120 mmUp to 1500 RPM47.1 CFM28.5 dB(A)

The be quiet! Pure Wings 3 120mm PWM Reverse 3-Pack is a set of three black 120 mm case fans rated at up to 1500 RPM and 47.1 CFM, aimed at builders who want quiet, affordable airflow with the clean side of the fan facing outwards. Part number BL137 includes three fans with fixed 500 mm cables and 4-pin PWM control. The reversed blade geometry lets you mount the fans as bottom or side intakes while the smooth front face stays visible through a glass panel.

Typically in stock with fast delivery across Cyprus.

Compatibility note: Standard 120 mm fans with 4-pin PWM connectors. No hub or splitter is included — connect each fan to a motherboard fan header or use a PWM splitter/hub (sold separately). Reverse fans move air in the opposite direction relative to the frame side — plan airflow direction before mounting.

Reversed blade design
Mirrored blades let the fan blow the other way while its clean front face points outward — ideal for bottom or side intake in showcase cases.
 
Rifle bearing, 80,000 h
be quiet! rifle bearings are rated for up to 80,000 hours at 25 °C, with low operating noise and PWM speed control via the 4-pin connector.

Frequently Asked Questions

Does the Pure Wings 3 120mm PWM Reverse 3-Pack come with a fan hub?
No. The pack contains three fans with fixed 500 mm cables; each needs a motherboard fan header or a PWM splitter/hub sold separately.
Is the Pure Wings 3 120mm PWM Reverse 3-Pack suitable for a radiator?
It works on radiators at moderate loads, but with 1.17 mmH2O static pressure it is better suited to case airflow; the High-Speed version (BL140) or Silent Wings Pro 4 are stronger radiator choices.
What is the difference between the Pure Wings 3 120mm PWM Reverse 3-Pack and other Pure Wings 3 versions?
The standard version runs up to 1600 RPM at 25.5 dB(A), the High-Speed version up to 2100 RPM with nine blades, and the Reverse version (1500 RPM) has mirrored blades for intake with the clean side facing out.
What do I need to know before buying the Pure Wings 3 120mm PWM Reverse 3-Pack?
These are non-RGB fans with 4-pin PWM control and a 3-year warranty. Make sure you have enough fan headers or a splitter for three fans.
Singular Expert Insight
Reverse fans solve a common showcase problem: bottom or side intakes normally show the ugly strut side through the glass. The black BL137 fixes that at a budget price; choose the white BL136 for white builds, or the standard BL141 for regular front intake. Browse our full case fan range for RGB and premium alternatives.
