Compact server fan for dense chassis

The TOPLAB 4028 measures 40 by 40 by 28 mm and runs on 12 V at .45 A with PWM control. It is built for 1U and 2U server enclosures where airflow must stay high in a tight vertical space.

PWM header simplifies speed management

A four-wire connector lets the motherboard or fan controller adjust RPM without extra wiring. The slim 28 mm profile clears low-profile heatsinks and dense drive cages that block thicker fans.
