Bulk 40 mm high-speed fans

This lot contains one hundred Delta PFB0412EHN fans in 4028 frame size. Each unit runs on 12 V and draws .72 A with a double ball bearing assembly. The supplier describes the airflow as hyper-violent for dense cooling tasks. The fans are new and packed in a single bulk lot.

Not for quiet or space-constrained builds

Buyers who need low acoustic output should look elsewhere because the design targets maximum airflow. Systems that cannot accommodate a 40 mm frame or a 12 V .72 A power draw per fan will require a different solution. The bulk quantity also makes this unsuitable for single-fan replacements.

Questions about this item

How do I install the 4028 12V .72A fan and what step is often missed?

Mount the 40mm frame using the four corner screw holes, connect the two-pin 12V .72A lead to a motherboard header or fan controller, and verify airflow direction arrows point the right way — the arrow check is the step most often missed.

What maintenance or replacement will the double ball bearing 4028 fan need later?

Double ball bearings are sealed and require no lubrication; plan to replace the fan only if bearing noise appears or airflow drops after extended 12V .72A operation.
