I bought a Noctua NF-A4x20 fan and it's 12 volts but the fan has 3 wires with black/red/yellow so ground, red (5 volts) and yellow (12 volts) but my molex to fan (12 volt) adapters only have ground and 12 volts and the pin arrangement for the adapter is putting the 12 volts to the red 5 volts wire on the fan. The fan is an FLX fan and not a PWM so should I modify the adapter to put 12 volts to the yellow wire on the fan or should the adapter also have red 5 volts to the fan or just 12 volts?
