Product Identity

The be quiet! Pure Wings 3 BL108 is a 140mm PWM case fan built for desktop PCs that need strong airflow with low acoustic output. Its 7 optimised blades and rifle bearing target users who want effective cooling without added lighting or noise.

Installation Notes

The fan uses a standard 4-pin PWM connector that plugs directly into any compatible motherboard header. No special tools are required, but builders must ensure the case has 140mm mounting points; the 1200 RPM top speed means cable routing should avoid blade contact.

Capacity and Limits

Airflow reaches 55 to 60 CFM at a maximum noise level of 21.9 dBA, which suits typical mid-tower builds and radiator setups. The rifle bearing is rated for 80,000 operating hours. Systems demanding higher static pressure or significantly greater airflow will exceed this model's comfortable range.

Domande su questo articolo

How do I confirm the Pure Wings 3 BL108 is running correctly after installation?

Connect the 4-pin PWM header to the motherboard. In the BIOS or fan-control software set a curve; the fan should spin up to 1200 RPM at full duty and drop to a low minimum RPM at idle. Listen for a smooth 21.9 dBA hum at maximum speed with no rattling or clicking from the rifle bearing.

What ships with the BL108 140mm fan and what must I provide?

The retail box contains one 140mm Pure Wings 3 fan with a 4-pin PWM cable attached and a set of mounting screws. You only need a free 4-pin PWM header on the motherboard or a compatible fan hub; no extra cables or adapters are required.

Which capacity or version of the Pure Wings 3 140mm should I choose?

This MPN BL108 is the single 140mm PWM model delivering 55 to 60 CFM at 1200 RPM with a 21.9 dBA noise rating and an 80000-hour rifle-bearing life. Choose it when you need one high-airflow 140mm fan for case or radiator use; multi-pack versions carry different MPNs.
