My motherboard is the EVGA Z390 Dark and I am wondering the manual says my Fan headers support "PWM/DC Fan Headers (2 amp)" is it possible to put 3 of the fans listed below on one header then another 3 on another header all using a splitter?

3 B12-PS Eloop on one fan header

Another 

3 B12-PS Eloop on another fan headers so 2 different sets of 3 fans on each its own fan headers. Sorry trying to explain to make it easier 

The fans will be all the same.

Just making sure I will be ok with a 3 way splitter

    Yes
     
    This may help you   Watts to amps calculator

    NoiseBlocker

    Mfg Spec sheet
     
    based on the fan in your link B12-PS


    Per Fan:
    Full speed ---> use 12V (DC) & 0.95 W = Current result in amps: 0.079166666667 / per Fan
     
    So Round this Up to 0.08 A +0.08A + 0.08A = 0.24 Amps / 3 Fans

    Per Fan:
    Start Spinning per Mfg 6.2 Volts & 0.95 W = Current result in amps: 0.15322580645 / per Fan


    So Round this  to 0.153 A +0.153 A + 0.153 A = 0.459 Amps / 3 Fans



     
    I preferred Fan Hubs to take the load off of the MB circuits & if hub is mounted close to your fans, you may only need 1 extension fan cable & not one for each fan to reach MB header while hiding the wire
     
    The one I like best SilverStone the Horizontal pin location makes routing wires easy

    Thanks for the suggestions and all I wanted to make sure that I would be fine with the fan headers just in case down the road I decide to just not do a  fan hub.
     
    Thanks for clearing that up and all I will def look into a fan hub. But like I said I wanted to understand that even without a fan hub that it would work. Wasn't sure how all that worked with multi fans on the header.
