Multi Fan Connector (4-Pin to 4x 3-Pin)
With this cable, you can power 4 fans using a single 4-Pin Molex plug that you connect to your power supply!
Since the cable is connected directly to the power supply, you cannot regulate the fan speed. The cable has a smart solution for this!
Two 3-Pin plugs allow a reduced voltage of 5 volts (instead of 12 volts). These two fans that you connect to this will therefore spin more slowly and thus produce less noise (for example, Case fans).
The other two 3-Pin plugs allow the normal 12 volts through, so that the fans run at full speed (for example the CPU fan or GPU fan).
This cable is a handy solution to control multiple fans!
