Questions about this item

What power connector does the F412R-12MB-23 need from my power supply?

The F412R-12MB-23 runs on 12 V DC, so your power supply must provide a 12 V rail with a matching connector for the fan's lead.

Will the 40 mm frame of the 4012 fit the mounting holes on my older 40 mm chassis fan slots?

Yes, the 40 * 40 * 12 mm dimensions match the standard 40 mm mounting pattern used on older cases and heatsinks.
