Questions about this item

Will this 12 V 0.35 A rear dual fan fit alongside the existing cooling in my Z820 workstation?

It is built as the direct rear exhaust for the Z820 chassis and draws 12 V at 0.35 A from the system fan header.

How can I confirm the 80 mm dual fan is spinning correctly after installation?

Power on the workstation and watch the rear grille; both rotors should spin steadily and the BIOS hardware monitor will report a stable RPM reading.
