140-to-120mm Fan Adapter

This blue adapter lets you mount any standard 140mm fan into a case that only provides 120mm screw holes. It removes the need to drill new mounting points in the chassis. The funnel shape directs airflow through the smaller ventilation opening. Four screws are included for installation.

Build Integration

The accessory fits between a 140mm fan and the case panel, aligning the larger fan with existing 120mm mounting patterns. It frees up the option to use higher-airflow 140mm fans in older or compact cases designed around the smaller standard. No additional brackets or modifications are required beyond the supplied hardware.

Sustained Airflow Behaviour

The funnel design channels air through the reduced 120mm aperture, maintaining a directed flow path under continuous operation. By avoiding turbulent leakage around the fan edges, the adapter preserves static pressure delivery to heatsinks or radiators during prolonged loads. The rigid construction prevents vibration or warping that could degrade the seal over time.

Questions about this item

How many mounting screws come with the 140 mm to 120 mm adapter?

Four screws are included so the 140 mm fan can be secured directly to the existing 120 mm screw holes.

Does the funnel shape of the adapter restrict airflow when running continuously?

The funnel design channels air through the 120 mm ventilation hole without adding measurable resistance.

What size case fan mounting holes must the chassis already have for this adapter to fit?

The chassis needs standard 120 mm fan screw holes; the adapter then accepts any 140 mm fan.
