120 mm Bionic Loop Rotor Fan

The Blacknoise NB-eLoop B12-4 is a 120 mm case fan that uses a bionic loop rotor to move air with reduced turbulence. It targets builders who want high airflow in a standard 120 mm mounting footprint without LED lighting. The white frame and blades suit clean, light-themed builds.

Compatibility checks before ordering

Verify that your chassis or radiator accepts a 120 mm fan with a 25 mm thickness. The unit draws power through a 3-pin connector, so confirm an available header on your motherboard or fan controller. Because speed control relies on voltage regulation, PWM-only headers may not adjust the 2400 RPM maximum.

Build quality and daily implications

A dust-protected Nano-SLI bearing and position-invariant magnetic design keep the motor sealed against particulate ingress. The anti-dust Makrolon rotor and reinforced fibreglass PBT frame resist deformation over time. Two pluggable cables are included for flexible cable routing inside the case.

Questions about this item

Does the fan come with any cables or adapters in the box?

The fan includes two pluggable connection cables for cable management.

Should I choose this 2400 RPM model or a lower speed version?

This model runs at 2400 RPM delivering 88.46 CFM airflow at 34 dNA noise; select it when you need maximum cooling for radiators or dense cases.

What does 88.46 CFM mean for my actual CPU temperatures?

At 2400 RPM the fan moves 88.46 CFM through a 120 mm frame, giving strong static pressure for radiator or heatsink cooling while the 34 dNA rating keeps noise moderate.
