I believe they're 120mm slots. Take a look at the full specs below.

Hmm, its either 140 or 120 fans, but could I measure it somehow?

No, I'm quite sure it's only 120mm. And what do you mean by measuring? Do you already have the Corsair 800D case or are you considering buying it?

Quote from Corsair 800D features:
"Three 140mm fans included, with the ability to add four more 120mm fans"

Those are 120mm x 3 on top and I would consider premium quiet fans like Noctua's
Yes that is the correct cable for the fans and I would connect them to the PSU before using the mobo connections, it's cleaner looking and keeps un-needed power from flowing through mobo. Another reason to use Noctua's as they are provided with speed resistors but I've found even wide open they are dead silent.

Ya thanks for answering, and notcuas are the ones I want even thou the color is wrong, and planing to put all cables behind the mobo connected my psu but should I do it even with the cpu? I use a noctua heatsink, and would 1 psu cable be enough considering that connector I linked can be built on or should I do like 3x fans then do a new cable to add the other 3 fans I got already inside?

I'm sure you could daisy chain up to 4 fans off one psu connection. I have kept mine to 2-3 fans per psu connection and run them wide open except for the two stock Corsair fans acting as puller fans on the other side of my H100 radiator. This is done to slow them down and quiet them down as they are crazy loud. Regarding the air cooler connection unless you have a 4 pin to two three pin jumper you'll need to run them off the psu as well and why not as the cooler you can run then better and there will be zero noise!. Then you can also investigate the Corsair link as well..........?

Ah, right. Noctua's are a good choice once you get over the colour. For some reason, they insist on making all of their fans hideous shades of brown. Anyway, 1 PSU connector should be fine for the three fans if you use that connector of yours.

Yes the Noc's are an acquired taste? I even called them and asked if they would reconsider as I felt that if they offered a basic black model they would sell even better. Oh......it was like I had just told him he was adopted ! The tone of the whole conversation turned and even though I'm sure they must get 10's of calls a week if not a day it was as if he'd heard this for the first time. It must be that beige and brown resonate less than black???lol

Alright thanks for all the info and now I can get a bit less cables sticking around since the ones to the noctua fans are rather long so atm they go a bit every in the chassi. So this is the last question before I get into action on fixing this. If I connect every fan to the PSU I wont get any reads from the sensors right indicating how warm the CPU is or that dont matter?
