I recently purchased an ASUS ROG STRIX Z390-e gaming motherboard, as well as the Corsair Crystal Series 570x case. My question has to do with how many fans can I use per fan header on my motherboard? The motherboard comes with only 2 fan header spots. Sorry for my poor use of computer lingo. I'm fairly new to all this. I want a total of six fans, and the fans I want to use are the corsair LL series LL120 RGB 120mm (six of these). Anyone know if I can use a 1-3 splitter and put those specific fans into each header on the motherboard?

Depends on the fans used.
Typically, no more than 1A on a given header - with most fans being ~0.3A.

Those are 0.3A fans.

You have 2x CHA_FAN headers, an M.2_Fan header and both CPU_Fan and CPU_Opt.

I wouldn't look to run more than a 2way splitter off any given header.
Which cooler do you intend to use? While not ideal, you could always have a case fan (or splitter) connected to "CPU_Opt", although would have no indeoendent control - it would be controlled by the speeds of the fan connected to CPU_Fan.

I don't see any reason you couldn't use the M.2_Fan either....
