Questions about this item

What voltage header does the fan need on my motherboard or controller?

The fan runs on a 12 V supply, so it requires a standard 12 V fan header or a compatible 12 V PWM/DC header on the motherboard or fan controller.

Will the 40 mm square frame fit the same mounting holes as my old 40 mm fans?

Yes, the fan measures 40 mm by 40 mm with a 20 mm thickness, matching the standard 40 mm square mounting pattern used by most 40 mm case and server fans.
