    Ok, so I'm building my first rig, I have a Corsair 500r case and ASUS P8z77-v LK motherboard and the fan connectors from the case are 3-pin and the motherboard has 4-pin connectors. So are there adapters that I can get to plug the mobo into and the fans into?(like both sides(mobo & fans) need their pins to plug into an adapter is what I'm getting at) Is it that easy? I went to a local parts store and the guy there told me he doesn't have anything like that and I should probably buy new fans and I really don't feel like that is the only option. Everything else I looked up regarding this cases fans and this specific mobo has nothing to do with the connectors so its leaving me to believe there is a simple solution that I am just missing here. Thanks for any input.

    You do not need any adapter; just plug the fan in and it will work. You will not be able to control the fan speed via PWM [which is the purpose of the extra lead]

    There are adapters to connect the fans to a 4pin molex connector from your pw supply however there really is no need to buy anything.

    BTW the fan connector is keyed so you cannot plug it in incorrectly [unless you really really force it]

    No I mean there are three fan connectors on the mobo that have 4-pin connectors showing; also, the fan connectors coming from the fans are 3-pin fan connectors. (pins are showing on both sides)

    I understand. You can use the 3pin fans on a 4pin connector. Even if you used an adapter, it is not going to do anything; the fan lacks the ability to use PWM. Your fan connectors looks like this correct?

    No my fan connecters have pins like the motherboard does. They both have pins that you need to insert into something.

    should I just get molex connectors and hook the integrated chassis fans to the PSU? but the case has speed control for the fans will this negate my use of controlling fan speed?

    Note: I would like to be able to use my speed controls integrated with the case.
