Where to plug in case fans?

[falconlover]

So, i want to buy Fractal Design Define r5 and replace case fans on 3 Noctua NF-A15 (one on rear side and two on front). And i really dont know where i should connect them. Thought about motherboard (Asus z170-A), plug two front fans with Y splitter into one header (is it even safe?) and one rear into another header, or is it better to plug all of them directly into psu? Or maybe i should use case fan controller? Help me with advice please

Repeat question same answer.
If you just must use the other fans then still the same answer as where to plug them in.

Yeah, i wanted to delete and redo this post but some dumb thing happened So will it be fine to plug two fans into one header on m/b using splitter? I am a bit worried about it

Zerk has already answered this before.
You have 4 fan headers on that board + a fan controller built in the case.

Why on earth would you want to use a splitter & a single fan header????

It makes no sense at all.
