Antec 900 Two fan wiring question.

post #1 of 4
Thread Starter 
Hello everyone and thanks in advance for any advice that comes from this post.

I'm about 99% done with my first build and I have a a question or two about the fan wiring with the antec 900 Two. There are 4 fans in total all with 4pin molex cables. Is there an adapter I can use that allows me to plug them directly into my PSU? http://www.newegg.com/Product/Produc...82E16817139010 Lastly, if I do connect them directly to the motherboard, do they start up when I boot or do they come on whenever the extra cooling is needed?

You could use either of these

Or just about any fan controller or adapter combo. Or just simply plug the 4 pin molex into the PSU directly, or are you saying that the fans are PWM controlled?

In that case, you would need something like this

And you would still plug into the 3pin sockets, but orient the fan plugs so that they line up and use only the red/black/yellow wires leaving the blue alone. Then you would hook the controller to your mobo's PWM (pulse width modulation) controller port which is usually the CPU port, but some have an extra one.

To answer the questions, the fans will come on with the system, unless you use a controller to manually or PWM control them.

Thanks I'll probably get a fan controller later on in the future. I have them all working now, was just me overlooking a cable that came with the PSU.
