I have a i7 2600k and i have a hyper 212+ on it with 1 fan currently and am looking to purchase 2 new fans for it. I want to move as much air as possible without to much noise. The one that came with it is only 21.2 - 76.8 CFM. I'm looking to get something that moves a little more air. It would have to be a 120mm fan. Also I have asus z68 deluxe board. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
As you can see i only have 1 cpu fan hook up. So im not sure how to hook up 2 cpu fans. So if you guys could help me with this problem that would be great!

you need is a push-pull with the fans, I'd keep the original fan and buy a second fan that has higher CFM and higher RPM and if your hyper 212+ came with a second fan mounting brackets, make sure the second fan is blowing out not sucking in, most fans have an arrow for air flow, what you want is both fans blowing in the same direction one pushing air into the fins the other on the other side sucking air out of the fins or else you can cause a vaccum in the heat sink

if you want to move more air you need a faster fan which then creates more noise. you can't get around physics, some fans make a little less noise and some make a little more but if your fan is hitting 1600rpm+ then it will make noticeable noise in a silent case. also CFM is pure marketing BS as there is no standard approach to it. I can take your CM 120mm with 76cfm on it, stick it into a package saying it moves 100cfm on it and sell it.

your best bet is finding a better fan that can still move a solid amount of air at a slower speed. try this scythe PMW fan out, ive used it on several heatsinks and it works great at keeping the CPU cool and keeping noise down.

Now how do i hook both cpu fans up with only 1 cpu fan connector? All of my other fan connectors on the MB are being used by case fans.

you have to give up one of your case fans for the second cpu fan, but you can use a molex connector ie old style hard drive connector for the case fan
