Andre-

So i need to buy one F12 for the rear (i want to replace it) and then i need 2 f14 front intake and 1 f14 exhaust, so one F2 and three F4, correct?.

Sorry for my English, but when you say "relocate the stock fans" you mean changing the p300 stock fan to the F12?.

Ok, whats the difference between F12 and F14? you said i should get two F14 Before, why should i get only F12 do you Think?

Is this a oem fan you are talking about? could you give me some links to some models? https://cdon.se/hemelektronik/fd-120mm-oem-flakt-p25502759?utm_source=kelkoose&utm_medium=cpc&utm_campaign=kelkooclick&utm_term=FD+120mm*+OEM-fläkt https://cdon.se/hemelektronik/fractal-design-silent-series-r3-120mm-fan-p31988710?utm_source=kelkoose&utm_medium=cpc&utm_campaign=kelkooclick&utm_term=Fractal+Design+Silent+Series+R3+120mm+Fa

You said Before "Get the Arctic F12 for the rear and the F14 for top and front" why should i get 3 F12 and no F14? whats the difference?

What is a stock fan? can you give me a link?

I think i will go with F12 PWM PST CO for the rear and the F14 PWM PST CO for top and front, 3 fans is good enough right?

How many fans does 3 free slots fit? PS i use NH-U9B SE2 for the PSU.

There is only 3 free slots?, so that fits 3 fans or how many?. PS i use NH-U9B SE2 for the PSU.

Would ARCTIC F8 PWM - 80 mm PWM Case Fan be a good extra case fan for the Phanteks P300?, if yes, how many should i get?.

I am not overclocking it, the i7 8700 should be fast enough for games as i understand it.

Is he talking about the Asrock b360 pro4 here? "if you attach a big two and half slot 1080/1080 ti graphic card (like those zotac ones), you only have 1 pcie slot to use, where as if you use an atx board you will have 1 for pci-e x1 and 1 for pcie x16 (likely wired x8 or x4)". www.tomshardware.co.uk/answers/id-3691463/risk-buying-asrock-b360-pro-8700-mobo-advice-appreciated.html Will it fit with my Aorus GTX 1080 Ti xtreme? And will The Gigabyte Aorus B360 Gaming 3 WIFI be able to use the full Power of the i7 8700?. im thinking of going with the gigabyte or Asrock one, what do you Think?.

The Gigabyte Aorus B360 Gaming 3 WIFI is cheap and has good Reviews, might go for that one if i dont find any better.

I am getting a locked one, the 8700. My Aorus GTX 1080 Ti xtreme needs to fit with the motherboard, some motherboards dont fit well with some graphics cards. I Heard Asus motherboards are bad?, bad drivers etc?.

MSi Z370 GAMING PRO CARBON is a cheap board, i might go with that.
