(Trying to post this for the second time so I'll try to keep it brief)
My upcoming build has two fan headers on the motherboard (MSI B450i Gaming Plus AC), but I have four total fans - one for the CPU (Noctua U12s using a Noctua NF-F12 fan), and three case fans (Corsair LL 120mm RGB).
After going back and forth on how to do this, I've decided I don't exactly want to bring in a hub or controller into the build. If I use a splitter, can I split the CPU fan header between the CPU cooler and the rear case fan? From what I've read, this would cause the rear case fan to basically be bound to the CPU fan in terms of its behavior. I've checked that amp wise, this all should work fine. The Noctua only uses .05A, and the Corsair fan .3A. Each header uses 1A.
Is this unheard of? I guess this setup would basically just cause the rear fan to rev up whenever the CPU fan revs up, which I don't see as an issue. Still, I want to make sure that this isn't frowned upon, or is something I should avoid.
If this is something I should avoid, I think I may be only using two of the case fans, and either sell the one I'm not using, or put it to the side until I work out some kind of hub situation. Does anyone have experience with this? I'm sure it has to be something ITX builders come across, hopefully. Thanks in advance!
tldr; Is it bad to split the CPU header between the CPU cooler and a case fan?
