Questions about this item
Will the 48 V 0.83 A rating let this fan run on my existing 12 V fan headers?
No, the unit is rated for 48 V and 0.83 A, so it requires a 48 V power source and will not operate from standard 12 V motherboard headers.
How can I confirm the 4250 RPM speed is being reached after installation?
Connect the fan to a 48 V supply and measure RPM with a tachometer or motherboard monitoring software; it should read approximately 4250 RPM when running at full voltage.
Does the box include mounting screws or a 48 V power adapter?
The supplier data lists only the fan itself at 560 g; mounting hardware and any 48 V power supply are not included and must be sourced separately.
