How many case fans can my motherboard support?

[detralt]

So my motherboard (ASUS Prime B450-plus) says it can support 4 fans, but the new case I want to but has 6 fans in total and I have one fan spliter laying around to accommodate the extra two fans, but my concern is would that draw too much power for the motherboard?

No it should be just fine.

I use this Sata powered hub to run my fans , keeps the build nice and clean.
