Thanks for the responses,
When I loaded iCUE, all the fans adapted to whatever the default profile is in iCUE and I don't think those RPM settings have changed since.
The fans that I have in my pc for now are the stock fans and the fans for H100i v2. The H100i v2 is connected to CPU_FAN, and the others are connected to SYS_FAN 1 and 2 on the motherboard.
I believe the CPU Fan Speed Control is set to Full Speed and the CPU Fan Control Mode is set Voltage.
The software that I have been using now is the Gigabyte App Center's SIV. I don't really know what software would be best to use. I can download iCUE again if needed. I also have Link installed so I can use that too.
I'm unsure how to know if my fans are tied to my coolant temperature rather than CPU temperature.
