URGENT: How do I connect the fan?

Last response: in Systems
Share

Hi everyone, I finally received my computer parts last night, ready to assemble. Everything went without a hitch until I got to the fans. I am using a Rosewill Challenger case, with a 120mm rear and front, and a 140mm top. The rear fan has a nice small three pin connector which plugs right into the SYSFAN spot on the motherboard. But the other two have two huge molex connectors, one female and one male! What the heck do I do with these? Thank you very much in advance :)

Best solution

if you plug the fan directly into the PSU, the mobo will not regulate it. It should connect to the mobo. Don't all the fans have the same connectors? Mine all had the 3 pin and were placed at various points around the mobo, from what i remember.

I haven't done this in years though so I'll defer to someone else.

And is it a problem if any of the cables are touching the mobo?


Very unlikely, but still try to move them around/stick them to anotherpart of your case.

If you fan is connected to your PSU, it will work at 100% performance 100% of the time.
If it's connected to your motherboard then the fans will only increase performance when heat builds up in your system.

I have my intake/exhaust fans connected to my PSU, and my CPU to the motherboard.

Front is intake... top is exhaust.

rule of thumb: front /sides are intake, back /top exhaust.

why not get an adapter to connect them all to the mobo? i have two front, two side, two top and top back... the back if i remember are connected to the PSU but its been a while since i've been in there. but theyre LED fans and have low RPM so its ok theyre on 100% all the time.

Okay, so I guess I'll just use all three fans, with two running at maximum. I might purchase a fan controller or adapter in the future. Thank you!

And one last question :) : For connecting the hdd, I have a blue cable that says sata 6gb/s, and an identical black one that says serial ATA. My hdd is 6gb/s, so which should I use?

EDIT: Also for the Optical drive.

Does your motherboard have SATA3 6gb/s ports? If not, then it does not matter which cable you use since the blue SATA3 cable is backwards compatible. Even then, I'm not sure a HDD benefits from the 6gb/s ports like a SSD would so the blue cable would not even give better performance (even though it will work just fine).

Now to wait a couple of days for the ssd to come to install windows...


Ok you definitely want to use the blue cable then instead of the black cable for the SSD as long as the SSD is a SATA3 drive. The SSD will really benefit from that SATA3 cable (as long as you are using a SATA3 port on your motherboard).
