For aesthetic appeal and because the summer ambient temperature in the room where my computer lives gets rather high I think I'll probably need up to five case fans to keep everything relatively cool. My issue arises from the fact that my Gigabyte H170N-Wifi only has one SYS_FAN header.
While I could drive them all from the PSU at constant full speed, I would greatly prefer to let the computer automatically configure the speed of all of the fans. To my understanding, splitters such as this should allow each fan to take power from the PSU and pulse width information from the motherboard to achieve the results I desire. However, after purchasing that cable for use with the three PWM fans that I currently own I have found that the fans run at high speed constantly. Adjusting speed via BIOS does nothing, and removing the four pin female part of the cable from the motherboard does not change a thing. It's pretty obvious that the cable is just allowing the fans to draw all possible power from the PSU and sending RPM info back for the motherboard to read but not adjust.
Is there a solution that will allow automatic adjustment of multiple fans from one four pin PWM header?
