Compact 40mm 5V fan for tight spaces

This TSUJ AUB0405HD measures 40mm square and runs on 5V power. It fits server chassis, inverter units and other compact enclosures where a 4020-profile cooler is required. The low-voltage design suits embedded builds and small-form-factor appliances.

Steady airflow under continuous duty

The fan is rated for constant operation in switch and server environments rather than short bursts. Its silent bearing keeps noise low during extended loads. Buyers who need higher static pressure or a larger frame will need a different cooler.
