Questions about this item

What voltage header do I need on my motherboard to run this 24 V fan?

The fan requires a 24 V supply, so your board must provide a 24 V fan header or an external 24 V source.

Will this 40 mm fan fit the same screw holes as my existing 40 mm cooler?

It uses a 40×40 mm frame with 20 mm thickness; verify your cooler’s mounting pattern matches those dimensions.
