Hey, I just bought a Rosewill Thor V2 case and put a ASRock Z77 Extreme 4 Mobo in with a Capstone 450 Watt Semi-mod power supply. I also have a SAPPHIRE Radeon 7850 GPU and a Zalman CPU air cooler. Finally a DVD/Blu-ray optical drive and 1 HDD.

Installation was more or less easy, but I am having trouble with wiring. For example, there are 2 cable groups coming done from the console fan controls labeled Fans A 1,2,3 and B 1,2,3, but there are also 3 Cha-Fan slots on the mobo. Further more there are 4 case fans, and 1 CPU fan.

The labeling is killing me and I feel so close to the finish line. I will post any other specifications you guys need if you can help. I tried google and youtube, but all I found were testimonials saying how easy cable management was and how they can believe how fast it went. Now I have loose wires and hurt feelings.

im not sure what the problem is but it just sounds like you're running out of places to plug in your fans

your psu should some with converters to plug in your fans into the psu rather than the mobo. plug in all the mobo power slots, and everything else can be run off the psu.

PM me if you need more help

From that description, it sounds like there are two integrated fan controllers that the chassis has (the knobs are on the top/front panel).

You can plug fans into those fan controllers or the motherboard. If you want a fan to be controlled by the A knob, plug it into the plug corresponding to that. Same for B knob, or the motherboard, though many motherboards won't support fan control for each header. Any option will run the fan. Actually, if you didn't have some of the fans running, that really wouldn't be a problem either.

CPU fan you probably want on the motherboard's CPU fan header.

You need to be a little clearer with your explanation but If i got it right...

Your case has 2 connectors that each controls 3 fans, you could plug these into the chassis fan connectors in your motherboard. I'm not sure what you mean by cpu fan connector? is there a 7th fan or are you talking about your cpu cooler? Either way that should have its own slot usually called cpu-fan on the motherboard.

I think Myrmidon was closest. My case has two fan speed knobs on top. The case came with two wires decending from this top console with each wire splitting into three connectors. One wire has A1, A2, A3 and the other B1, B2, B3. My case also has 4 fans (Top, Front, Back, and Side).

The mobo (as far as I can tell) has 3 places that seem to also fit the wiring from each fan. I do not know how to wire this set-up properly because the directions are not entirely clear and this is my first build. I plugged my CPU cooler into CPU-Fan-1,

Do I have to plug my fans into the mobo? Or am I going to have more sockets then I need?

Can you run an Optical drive and a HDD off of one SATA power cable or should each have its own dedicated cable? I only have 1 of each.

It's not a problem to have unused slots for fans or anything else. If you plug something in and it fits, it will at least work—other than than the wrong pins for the front panel to motherboard connectors. Plug the fans into whatever you want. If you want to be able to control the fan speed through the knobs, then wire them to one of the chassis fan controllers...(no, there's no difference between A1 / A2 / A3, or between B1 / B2 / B3). All this stuff isn't explained explicitly because it doesn't matter. Pick any.

There should be five SATA connectors in all, probably on two separate strings. Any way that gets a correctly-fitting plug into every device that needs power, is okay. (The connectors are wired in parallel obviously, current along a SATA power connector strand is pretty low, particularly for the wire gauge used.) Unless you use excessive force to plug something in very very wrong, you're not going to damage anything. Actually, you wouldn't damage most things, other than mechanically, by wiring it wrong.
