This Buffalo cooling fan is built as a one-for-one spare for the DriveStation Duo enclosure. It arrives new and carries RoHS certification. The unit weighs approximately 0.90 oz and fits the existing mounting points without modification.

Suits owners of a noisy or failed original fan

Users who need to restore factory airflow in a DriveStation Duo will find this part matches the original dimensions of 2" by 2" by 0.4". Builders working on custom NAS boxes, other drive enclosures or standard PC cases should look elsewhere because the mounting pattern and connector are specific to this Buffalo model.

The only specification that determines fit is the stated compatibility with the Buffalo DriveStation Duo storage drive. No universal screw spacing or standard header is documented, so verify the exact enclosure model before ordering.

Questions about this item

Does this replacement fan fit both drive bays of the DriveStation Duo or only one?

The fan is a single unit designed for the DriveStation Duo enclosure; install one fan per bay if both positions need replacement.

What does the 0.90 oz weight mean for installation inside the DriveStation Duo?

At 0.90 oz the fan adds negligible mass and mounts directly into the existing screw holes without stressing the chassis.

How does the 0.4 inch depth affect airflow inside the DriveStation Duo?

The slim 0.4 inch profile fits the tight clearance between drives while still moving enough air to keep the hard drives within safe temperatures.
