Ten 40 mm double-ball-bearing fans

This pack supplies ten 4020HH12B-NF4 case fans built around a 40×40×20 mm frame. Each unit runs on 12 V and draws 0.24 A through a standard three-wire lead. The double ball bearing is intended for continuous operation in compact enclosures.

Fits tight 40 mm mounts with three-pin headers

The 40 mm square footprint suits small-form-factor cases, server trays or appliance chassis where larger fans cannot be installed. A three-wire connector provides tachometer feedback to the motherboard or fan controller. Ten units allow multiple intake and exhaust points or spares for maintenance.
