What this adapter does

The BGears Fan Adapter 140mm-BK lets you mount a 140 mm fan onto a case panel drilled for 120 mm screws, and it also works in reverse to fit a 120 mm fan into 140 mm holes. It ships with four mounting screws so no extra hardware is required.

The critical spec

The funnel-shaped frame channels air through the smaller 120 mm opening without drilling new holes in the chassis. This single geometry change determines whether your chosen fan will line up with the existing screw pattern.

Build integration

The black adapter sits between the fan and the case panel, adding negligible depth while converting the mounting pattern. It frees you from modifying the case and works with standard fan screws already in your build kit.

Questions about this item

How does the funnel design affect airflow when a 140 mm fan is mounted on a 120 mm hole?

The funnel shape channels air smoothly through the smaller 120 mm ventilation hole, reducing turbulence that a flat plate would create.

Which mounting patterns does the adapter convert between?

It converts 140 mm fan screw holes to 120 mm case holes and also works in reverse, letting a 120 mm fan mount on 140 mm case holes.

What hardware is included for installation?

Four screws are supplied, covering both the fan-to-adapter and adapter-to-case connections.
