Ok , trying to mess around with this yet again. I have the settings in the bios as they should be (advanced)to allow variable speeds. ET6 just ran an update through the program itself so I am assuming it is the most current version. I definitely have it plugged into the right header on the board as its the only on close enough for the fan cables to reach. The system fan header is on the opposite (front) side of the board and doesn't come close to reaching. Seems like a really poor layout. Regardless, bios setting are correct, it's plugged in correctly, and it should be the most current version. One thing of note that is obviously not right, when I change the setting in windows ET6 from default to advanced, it will not retain the selection. It appears to at the time, but if I close it or reboot, it reverts right back to default. I suspect that somewhere in there is the problem. Any suggestions as to why that might be happening? I am really surprised how much time I've had to waste to try and get something so routine to work. Thanks to those who have offered suggestions, but I don't know what else to look at.
