40 mm 12 V PWM fan kit

Three 40 mm fans operate at 12 volts with four-wire PWM control and dual ball bearings. Each unit measures 40 by 40 by 28 mm and matches the AVC 4028 form factor. The set is suited for server chassis or compact enclosures that need focused airflow.

Limited to three 40 mm units

The pack supplies exactly three fans, so builds requiring more than three cooling points will need additional kits. Buyers needing larger diameters, different voltage rails or non-PWM wiring cannot use this set.

Questions about this item

Will the 4-wire PWM connector on these 40mm fans plug into my existing 12V motherboard header?

Yes, the 4-wire PWM connector is a standard 12V fan header interface and will fit your existing motherboard fan socket.

How can I verify the dual ball bearing fans are spinning correctly after installation?

Enter the BIOS hardware monitor or use a fan-control utility to confirm each fan reports a stable RPM reading at 12V.
