How to hook up 7 case fans to power supply?

So I have an Antec DF 85 case, and it comes with 7 case fans. These fans all have three pin connectors on them. They are not connected to each other in any way, and I apparently need 7 three pin connections on my motherboard in order to hook them all up. My motherboard has 2x three pin connectors to hook these fans up to, so I have five fans left to connect.

My question is, how in the world am I supposed to get these fans connected? Do I have to buy 5x three pin to molex connectors, daisy chain them together, and then hook up to the power supply that way? It just seems insane in my opinion for a $170 case to be that cheap and not include molex connectors on the case fans, and it would be about $20 and over a week of shipping just to get the three pin to molex adapters. Is there a better way to go about connecting these fans, or is buying 5 adapters the only option?

Thanks!

That's an easy one! Just get a fan controller! Not only do they allow you maximum control over fan speed and fan noise, they allow you to hook up many more fans that most motherboards allow. Here is a good one:

Hope that helps! :)

The thing is, I don't care about controlling them since the case already has a built in fan controller. I just want to be able to hook up all of these fan at all, as I plan on running them full tilt for maximum performance anyways.

Found this on Ebay... http://www.ebay.com/itm/4-Pin-Molex-to-6-x-3-Pin-Fan-Sp...

Would this pretty much be my best option, hook six of the fans up to this, then to the power supply via molex? And leave one of the fans hooked to the motherboard?

Seems like this would certainly be the cheapest, and still look decently clean.

At only $13, there's not much to lose, but I certainty still recommend a high quality fan-controller. I don't see what the problem with this is. Plus the two molex on the one I recommended means theoretically double power for the fans.

The one on ebay is a third of the price and would accomplish the same thing, would it not? I just want to be able to hook the fans up, controlling them isn't an issue with this case as it has a fan controller built in. I'd just like to spend as little as possible on this, as it's something that should have been included in the case in the first place as it is required for it to run. As long as it allows my fans to run, I'll be happy with it
