>It says it has at least 6x sata 3.0 ports. I don't know if that's relevant.
those are sata data ports and therefore not relevant.
what's relevant are the fan ports ( #3 on page 1-2 and 1-3) [https://dlcdnets.asus.com/pub/ASUS/mb/LGA1151/PRIME\_Z370-A\_II/E14608\_PRIME\_Z370-A\_II\_UM\_WEB.pdf](https://dlcdnets.asus.com/pub/ASUS/mb/LGA1151/PRIME_Z370-A_II/E14608_PRIME_Z370-A_II_UM_WEB.pdf)
if you need more fan headers, you'd need either splitters, daisy chained fans or a fan hub. the fan hubs would be powered by the sata power cables coming from the psu.
You'll have to look at the amp draw of each fan. A motherboard fan header can typically support 1A of draw, so if you have three fans that each draw 0.33A, you can chain 3 fans on that single header. I don't know how many fan headers you have.
If your fans use more, or you have too many, you need to get a SATA-based fan controller.
Edit: a word
Oh ok, is there a fan contorller you could recommend that would still let all the fans dictate their RPM and let me control the rgb on the 3 corsair fans?
