Where to plug in radiator fans into my motherboard?

post #1 of 3
Thread Starter 
Dumb question but...I have a setup with 4 (3-pin) fans in total, 2 intake and 2 exhaust. My upcoming watercooling build will have 2 dual 120mm rads, 1 intake and 1 exhaust. Where exactly will I plug in my fans for my cpu header? I currently have all my fans running from this multi fan port which is plugged into my 3 pin header on my motherboard. Would it be ok if I were to just not plug anything into my cpu header? will the computer even boot up? By the way, my loop will be a cpu loop with a gpu loop. I also have a couple of PWM fans...maybe just use 1 PWM fan and just use 3 (3-pin) fans? What would you guys do?

It is ok to have nothing plugged into the cpu fan header, in the bios under monitoring you should be able to turn off monitoring of that header so you wont get any warnings when nothing is plugged in. I would recommend having your fan controller plugged into a molex connector (big 4 pin connector that old cd and hd's used) and not the motherboard as it would put less strain on a motherboard, since 3 pin motherboard connectors are generally meant for one fan.

ok thanks, I'll look around to see what I can do in my case.
