Feature:
The cable is a 5V USB port to a small 3-pin fan cable, which allows you to use a USB connection to power most chassis fans, while either 3-pin chassis fan power adapter cables will work.
The starting voltage of the fan must be 5V or below (fans with a higher starting voltage will not work).
The 12V fan will operate at a reduced 5V voltage to achieve silent operation.

Note: The use of this USB adapter cable for the chassis fan will reduce the fan's speed by 60%.
