Crosair Fans Options

Hi can i get some advice please, I am in the middle of my first build, I will keep it simple my specs are here but my problem is i don't have most components yet!! But next couple off days so my dillemma is I would like to run 4 fans, but one connection on mobo, is there anyway I could run two fans off the psu, or can i use a splitter i can only seem to find a 3 way, 4 way seems dodgy.

I ask because I would like to order and be up and running for the weekend dont really want to run off two fans at first boot



Many Thanks in advance
