Delta 40 mm Server Fan

The Delta GFB0412VHF is a 12 V server fan built to the 40x40x30 mm form factor. It draws 0.54 A and is intended for compact enclosures that require high airflow in a small footprint. The unit is supplied new and matches the 4030 size class used in many rackmount and embedded systems.

0.54 A Current Draw

At 0.54 A the fan demands a 12 V header or supply capable of delivering that current continuously. Builders using standard low-power motherboard headers should verify the header rating before connecting. Systems limited to lower-current headers will need an alternative fan or a powered fan hub.

Questions about this item

How loud will the 0.54 A current draw make this 40 mm fan in a typical case?

The 0.54 A rating at 12 V shows the electrical load; actual acoustic output depends on the fan's internal motor design and the airflow restriction inside your chassis.

Does the three-wire connector on this 4030 model report speed to the motherboard?

The GFB0412VHF uses a standard three-pin 12 V header; the third pin carries a tachometer signal so the board can monitor RPM.
