Builders needing a small 12 V cooler

Questions about this item

Does the MGT40012ZB-R20 need a 12 V three-pin header to run?

Yes, it draws .22 A at 12 V and uses a three-wire connector that plugs into a standard 12 V fan header on the motherboard or controller.

Will this 4020 fan fit in the same 40 mm mounting holes as my old 40x40x20 mm cooler?

The frame is 40 mm square and 20 mm thick, matching the 4020 footprint, so it aligns with existing 40 mm screw holes.
