I have a set of fans in the following two connections on the motherboard
I went into the bios to adjust the qfan curve on them and then looked at the monitoring screens for the fan speeds.
Chassis Fan 2 and Chassis Fan 3 are showing fan activity including the CPU but Chassis Fan 4 shows no fan activity. So looks like the motherboard is reporting the wrong fan ports in the bios unless I'm looking at this wrong?
