Question Which corsair fans do i get?

[MrDreamerz]

I'm building my first gaming pc so far i got the GOLDEN FIELD Z21 PC Case and a GIGABYTE Z390 AORUS PRO WIFI LGA 1151 (300 Series) Intel Z390 HDMI SATA 6Gb/s USB 3.1 ATX Intel Motherboard, (i'm gonna get a unlocked i9 )
I wanna buy this, "https://www.newegg.com/Product/Product.aspx?item=N82E16835181151 " but i need more corsair fans but theres different kinds and im not sure which to get, i just wanna be able to control them from the software and a separate manual controller. Any help will be much appreciated.

heres 2 i found not sure which i need if any of them, im looking to get a 3 or 6 pack.

I think most of them are same. All fans don't really make much difference. The important thing is that the air duct of the case is good.

What if i have a
CORSAIR - HYDRO SERIES H100I RGB PLATINUM 120MM PROCESSOR LIQUID COOLING SYSTEM WITH RGB LIGHTING
do i need to get corsair rgb fans or can i get a different brand of fans?
corsair fans are expensive and i want 7 of them to put in my build.
i want the rgb lights to sync.
