The ZM-NB47J does not require a fan, and thus does not need to be powered and does not create noise or vibration.
The Northbridge chipset can be cooled down to an optimal temperature without generation of noise. The ZM-NB47J is compatible with all Northbridge chipsets that do not have a built-in graphics chipset. Note - ZM-NB47J cannot be used on motherboards that lack mounting holes around the Northbridge chipset.
