I believe I already know the answer to this, just looking for confirmation before I finalize it. My motherboard headers support 1 amp per header and each of the corsair 140 mm fans I intend on using have a rated current of .3 amps. Unless I am missing something or not understanding something correctly, this means I could run y splitters to each of my fan headers to support the 6 case fans I want to use without drawing the maximum power, right? It's been a while since I've built a pc and I just wanted to insure that I am not missing something before I go ahead and do this.
