Quiet 140 mm case fan

The Blacknoise NB-eLoop B14-3 is a 140 mm case fan built around a bionic loop rotor that reduces air-stream noise. It runs at 1400 RPM and produces 28.5 dBA while moving 104.93 CFM of air. The NANO-SLI magnetic bearing is position-invariant and dust-protected for long life.

Bionic loop rotor airflow

The defining specification is the bionic loop rotor design, which delivers higher cooling power at the same revolution rate compared with conventional axial fans. This geometry cuts turbulence so the fan achieves 104.93 CFM at 1400 RPM with only 28.5 dBA. Builders who need that balance of airflow and quiet operation should choose this model.

Radiator and chassis headroom

At 140 mm by 140 mm by 29 mm the fan fits standard 140 mm mounts on cases, CPU coolers and radiators. It comfortably handles typical chassis exhaust or radiator push-pull duties at moderate speeds. It runs out of headroom in builds that demand extreme static pressure or significantly higher airflow than 104.93 CFM.

Questions about this item

What does 1400 RPM mean for airflow in a real build?

At 1400 RPM the fan moves 104.93 CFM, providing strong cooling for cases, CPU coolers or radiators while keeping noise at 28.5 dBA.

How does the 3-pin connector limit speed control?

The 3-pin connector allows voltage-based speed control from the motherboard, so fan speed varies with voltage but PWM precision is not available.

Will the 29 mm depth fit my chassis or radiator?

The frame measures 140 mm by 140 mm by 29 mm, so verify your case or radiator has at least 29 mm clearance for this thickness.
