Connecting 150mm fan to a 4 pin molex connector
I'm getting this fan (being shipped), it's a nasty 265 cfm .
As you can see carefully in the pic the connectors for the fan are simple positive and negative cables with no connector attached. I need it to be in a 4 pin molex connector, how can i connect it to the connector, and which pins should i connect?

Red connects to +12v which is yellow wire from your PSU
and Black coonnects to Ground (0v) which is Black wire from your PSU

Do you have an old fan, old power supply, or a local computer shop or radio shack?
these need to be connected to the yellow wire and the black ground right next to it on a standard 4 wire molex...
technically you could just splice in directly using some spare wire...

Mingyu01 is right about the colors, you can connect them easily, just find an old psu and tear out some molex connectors, sodder them to the fans wires and plug it in. as long as its 12v it shouldnt do anything to your psu.
I took a similar aproach to what you did.
My case has 4 120mm fans mounted on the 300mm side port. I estimated the intake capability of my 4 side and 3 front intakes to be 544cfm pull strength, theoretically. Thats about as much cfm as my car sucks up. We are pushing the line on how much air we really need to pump into our cases here. =)Mild Computer Repairman By Day

You can use a 4 pin molex connector in your system. Each of the little pins in the connector can be removed from the plastic part. They have little metal flanges that stick out from the side of the pin, these hold the pin in the pastic connector. Using a needle or VERY small screwdriver you can depress the flange and the wire and pin will pull out of the molex connector. Then you can solder your fan wire to the wire/pin you removed from the connector and then place it back in the connector.“Those who desire to give up freedom in order to gain security will not have, nor do they deserve, either one.”
