Fan control BIOS vs SIV on Z97X-Gaming

[wowThatsBad]

cpu_fan, cpu_opt, and the three case fans can be set independently of each other in the BIOS. However, they seem to have 0 effect whatever I set them to (all are 4-pin fans, with the cpu_fan being a water cooler pump).

Once in Windows 8.1, I can use the system information viewer (easy tune will not install on my system). If I use silent, it sets all fans to about 900 rpm except the cpu_fan which I believe it leaves at standard.

which takes precedence? I'd rather use the BIOS settings, and set all case fans to quiet and cpu and cpu_opt to standard.

Any ideas?

If installed SIV (part of App Center) you run a service called "GIGABYTE Adjust" and will be called AdjustService.exe (also loads your XML configs from SIV/Profile) under Task Manager processes. That, in turn, will run thermald.exe which is what actually monitors your CPU/MB temps and reports back to AdjustService.

If you are running that [software] it will override any BIOS changes made (edit ->) to the fan PWM settings.
