fan connectors question on Gigabyte K8NF-9

[Atropos13]

So I just got a Gigabyte K8NF-9 nForce4 mobo and was setting it up in my old ATX case. I have 2 fans in there (front and rear) plus the CPU fan and the fan over the power supply, making 4 total. Anyway, on the motherboard there is a clear place for the CPU fan plug and one my generic fans (the rear one) seems to plug into the power supply. My problem is that I have the fan over the power supply and the front fan, both with 3 prong plugs, and only 1 connector on my motherboard. There is one other fan connector labeled NB_FAN (in the manual it says Chip Fan Power connector) but it is for a 2 prong plug. So any suggestions about what I am to do to get all my fans hooked up? My old mobo had 3 of the 3 prong connectors so this wasn't a problem with it. Thanks for the help!

well an option would be to buy a 3 pin to 4 pin molex connector and just hook it up to the psu, otherwise i am not sure how you could get them all on the mobo. and that chip_fan plug is usually for the nf4 chip, but i am not sure why it is a 2 prong. do you even have a chipset fan?

There is no fan on the chipset, just a heat sink. As for you suggestion to get a 3 to 4 pin molex connector, what is the PSU? I looked around on my board and in the manual and couldn't find anything.

Lastly, if I can only hook up one of my fans, which one should I connect? I am assuming the one on my power supply is important, so that leaves the fan on the rear or the fan in front. Suggestions?

PSU is the power supply unit, sorry. well the power supply fan usually runs regardless if plugged into the bourd, usually they just have it so you can monitor the rpm's (look at the cabel coming from the power supply, if it has two wires then probably just to monitor, if it has three then maybe it needs the mobo for power, but i doubt that) i would connect the front and back fans to the mobo so you can monitor them, but in the end, it really does not matter, as long as they are getting power and spinning then you are fine. the mobo plugs are kinda just for the added benefit of being able to monitor or adjust their speeds.

Thanks Reg07, that was great info. You were right about the power supply fan not needing to be plugged in. Now I have all my fans running. Much appreciate the help!
