Hello,
I recently build a new mini-itx system in the Phanteks shift case.
The motherboard (strix z370-i) only has a CPU fan header and a single chassis fan header.
So i decided to get a phanteks 4pin y splitter, which i have now plugged in, so that it splits the cpu fan header between the radiator intake fan, and a chassis intake fan.
The problem now, is that it sounds like one of the fans is just going full throttle, while the other is controllable. I was hoping the speed set on the CPU fan header, would reflect on both fans? is something wrong, or have i misinterpreted how a fan splitter should work?
