How many splitters would I need?



That sounds about right. If the splitters go from 1 to 2, and you have three of them, that makes 6 fans. Just make sure to have 3 fan headers on your motherboard :)

Without knowing what motherboard you ordered that'd be kind of hard to tell how many you need. Motherboards typically have varying number of fan headers. 4 splitter for 6 fans seems like you'll have 1 splitter left over, maybe 2 if one of those fans is for your CPU.

Please, give more details on all components.

What type of splitters are you wanting to use? I'd suggest a PWM fan hub instead, https://www.amazon.com/Phanteks-PWM-Fan-Controller-PH-PWHUB_01/dp/B00M0R05WE?SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag=duckduckgo-ffab-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B00M0R05WE

Only thing is being sure all the fan cables reach it, I had to use an extension on one or two fans.
