I recently built a system using the SilverStone GD05B case and the ASRock Pro3-M motherboard.
The build went smoothly except I can't figure out how to control the case fan connected to the 3-pin PWR_FAN1 header on the motherboard. SpeedFan controls the speed of the two case fans connected to the 3-pin headers labeled CHA_FAN1 and CHA_FAN2 without any trouble.
SpeedFan reports the speed of all three case fans but only controls two out of the three.
Any SpeedFan experts or Z68 Pro3-M owners here who could shed some light on the issue?
Notice Aux1 Fan is running much faster than Sys Fan and Aux2 Fan. (P.S. Should I be concerned about the reported hard drive temperature?)
The case fan connected to the PWR_FAN1 header shows up as "Aux1 Fan" here.
But only two case fans, the CPU fan, and the GPU fan show up on the Speed tab.
Any help would be greatly appreciated,
