A 40 mm 12 V case fan drawing 1.08 W for compact cooling

  • Compact 40 mm frame fits tight chassis spaces

  • New condition ensures full performance from first use

4020 12V Case Fan for Compact Builds

This 40 mm square fan runs on 12 V and draws 1.08 W, making it suitable for tight chassis spots where a larger cooler cannot fit. It targets builders who need a simple airflow upgrade for small-form-factor cases or replacement cooling in legacy hardware.

Straightforward Two-Wire Installation

The unit connects with a standard two-pin header so mounting takes only a few screws and a plug-in. Because no PWM or speed-sense wire is present, the fan runs at full speed whenever powered, which can be audible in quiet environments and offers no automatic thermal control.
