Where to put fan plugs?

[Sceptr]

I have a Asus Rog Maximus xi Extreme mobo https://dlcdnets.asus.com/pub/ASUS/mb/LGA1151/ROG_MAXIMUS_XI_EXTREME/E14681_ROG_MAXIMUS_XI_EXTREME_UM_V2_WEB.pdf

A Corsair 750D case https://www.corsair.com/us/en/Categories/Products/Cases/Obsidian-Series%E2%84%A2-750D-Full-Tower-ATX-Case/p/CC-9011035-WW#tab-downloads

And a Corsair H150i cooler https://www.corsair.com/corsairmedia/sys_master/productcontent/H150i_PRO_QSG.pdf

I'm not 100% sure where to plug in the fans, i have plugged the three fan leads from the processor cooler head into the three leads from the H150i which is mounted on top of my case the other leads from the cooler are plugged into the CPU_FAN on the mobo and the USB2_E78 usb plug at the bottom of the mobo.

Now i have a fan at the back and two fans at the front of my case to be plugged in. I have four RAD1A_FAN, RAD1B_FAN, RAD1C_FAN and a RAD1D_ FAN spare at the top of the mobo and a CHA_FAN1 plug at the middle back of the mobo and a CHA_FAN2 at the front of the mobo and four more RAD2_FAN's at the bottom right of the mobo

The mobo is also designed for a Water Fan system which i'm not using for now, i'm just using the Corsair Water cooler mounted on top of my case.

So where do i plug the Back single fan and the two front fans into? I'm assuming here that the Three fans on top of my case are correct plugged into my processor, please advise if not.

you are correct to have plugged the radiator fans into the AIO pump leads. and the rpm monitoring to the cpu fan. the rest i would do like this

chassis fan header > splitter > chassis fans

or you can get a fan controller if you want to be able to independently control each chassis fan.

Don't need no splitters, just plug your extra case fans into the motherboard fan headers where ever there is room to plug them into.

The top back case fan (three pin) can go into the CHA_FAN1 at the back of the mobo

The front top case fan (three pin) can go into CHA_FAN2 at the front of the mobo

The bottom front case fan when you say plug them into the Fan Headers do you mean the RAD1_FAN A,B,C,D or the RAD2_FAN A,B,C,D plugs and does it matter if i say put the front bottom fan into the RAD2D_FAN plug which is bottom right of the mobo so closest?

Also the RAD_FANS do they require molex power? I'm assuming the 2 CHA_FANS are powered by the mobo?

Any 3pin or 4pin pwm fan can plug I to any of those headers, it doesn't matter. As long as the cpu cooler is plugged into cpu_fan header

Awesome thank you guys and yes the cpu fan is plugged into the CPU_FAN on the right of the two plug options and not the CPU_OPT which is left of the two plug options.
