You could be suffering from the same problem I had.
I have the same MoBo, everything worked fine, only CoolNQuiet wouldn't work.
The problem is that Asus screwedup the ACPI spec in the bios, or something like that.
I needed a kernel patch to get it running.
I made en entry in the HCL, you can check it here
If you need further help, you can ask me.
