Three white 120 mm PWM fans with reversed blades

The Pure Wings 3 BL136 triple pack delivers three 120 mm case fans finished in white. Each unit uses a 4-pin PWM connector and reversed blade geometry designed for side or bottom intake positions. The rifle bearing is rated for 80000 hours of operation. They suit builders who want matching white intake fans for a showcase build.

Standard 4-pin PWM mounting

Installation follows the usual 120 mm screw pattern and a single 4-pin PWM header per fan. The reversed blades spin so the clean side faces the interior, which is ideal for side or bottom intake but means the fan exhausts toward the panel instead of away from it. Builders who need conventional front-to-rear airflow should choose the non-reversed version.

PWM control limited to motherboard header

Speed regulation depends entirely on the PWM implementation of the connected header; minimum RPM can be very low for quiet running but the exact floor varies by board. No RGB or addressable lighting is included, so colour synchronisation with other components is not possible. Buyers who want per-fan RGB control or software-monitored tach feedback beyond basic PWM will need a different product.

Questions about this item

How can I confirm the Pure Wings 3 BL136 fans are running correctly after installation?

Connect the 4-pin PWM connectors to your motherboard and use BIOS or fan-control software to verify each fan spins and responds to speed changes; the rifle bearing is rated for 80000 hours of operation.

What comes in the triple pack and what must I purchase separately?

The pack contains three 120mm white Pure Wings 3 reverse-blade fans with 4-pin PWM connectors; mounting screws are typically included, but fan splitters or a PWM hub are not supplied if you need to run all three from one header.

Which version should I choose for a side or bottom intake in a white build?

This BL136 triple pack provides three reversed-blade 120mm fans in white, designed specifically for side or bottom intake positions where the visible front of the fan faces inward.
