I have Kraken x61 installed at the top, ASRock Extreme4 x99 motherboard already in the case.
now before I got onto hard drives and connections I wanted to make sure to connect all the cpu fan headers. however I am stuck;

in the ASRock extreme4 x99 manual I can only find 2 cpu fan connections, one seems to be 4pin, and the other 3pin,

The kraken at the top has 2 fans as seen on photos, each fan seems to have 4 pin connector, as well as connectors from the fan, ( I believe one more 4 pin) connection, I am all confused how to arrange all these connections with the motherboard, the Kraken Manual online also states 3pin power cable from The Pump to 4pin 'CPU-PWR' on the motherboard,

I will be checking online for any instructions if anybody has any suggestions please let me know,
I didn't even start connecting to thermaltake case's back and front fans to anywhere yet. I was hoping this motherboard since it is new and high performance, it would support quite a few fans?

Yes I did, I went with 2011 socket instructions, but before I power everything on for the first time I wanted to make sure,
on Kraken x61's instructions, it states "Connect the 3-pin power cable from the pump to the 4-pin CPU-PWR connector on the motherboard"
so when I do that and find the CPU PWR 4 pin, one pin on one side is still uncovered, I am assuming that is normal?

The thing is on the motherboards manual it is named "CPU_FAN1" which is that 4pin, (there is also 3 pin CPU_FAN2) right next to it, on Kraken's instructions it is named CPU-PWR, so thats whats confusing me,
there is also other Headers on the motherboard, named CHA_FAN1, CHA_FAN2, CHA_FAN3 and PWR_FAN1
but I am thinking Kraken x61 meant CPU_FAN1 on the mother board?

Yes, you're good. The 4 pin fan CPU fan header is designed for PWM (pulse width modulation) fans. By plugging in the non-PWM pump (3-wire), you are bypassing the PWM controller.

The USB connection and the software allows you to control rad fan speed. And possibly pump speed, although I'm not sure about that part.

Probably too late now, but the best way to test out a new board is to breadboard the system first. Outside the case, connect just the PSU, CPU/cooler, memory, and monitor (no card if you have iGPU). Momentarily short the two pins that that power button would connect to for starting. See if you get a display and can boot to BIOS. If all is good, then shut down* and proceed with the build. And double check that you don't add an extra standoff under the board that isn't used. That's a common mistake. Not all boards will use all the standoff for ATX, mATX, etc.

* you can either hold those two pins shorted until the system shuts down, or just turn off the PSU at the switch.

Clutchc Everything worked and I see the UEFI Bios First boot up Can you believe it??? I only asked one question something I realized strange was No Fan Movement on GPU Fans at all (EVGA geforce 980ti AC 2.0) It has 2 fans itsef, but even though its lights are ON, there is no life on its fans, my only possible guess is it doesn't kick in at all until it is really working, but it is still working because I am on UEFI Bios so I thought they would at least try to keep the GPU cool?

Thanks again for the support.
I can't believe I am seeing this screen as we type;
