I've been having some issues with fan control of my GPU's in Windows and I've tried MSI Afterburner and EVGA Precision XOC.  For some reason, even if I set those to set the overclocks for my cards on startup (which they do), the fans never kick on if I've got it set in Auto mode.  (Haven't tried just setting a single fan speed b/c I'd rather they ramp up and not stay full blast the whole time.)  I don't know if it's because they're on the risers or not, but does anyone know any windows based command line utilities that will allow me to set GPU/Memory Clocks and Fan Speed/Curves through a command line in a windows batch file?  I know Coolbits is out there for Linux, and I've seen a few versions that are 12+ years old that are supposedly windows based, but not sure I'm willing to try them.
