Have been running this for half an hour,
Thus far the fans are staying higher speed, 3400 and 4000 rpm,
The 4k one seems to be going just fast enough to scream a little. Which is to bad, would like to get rid of the squeel, the howl I can live with.
But the temps are sitting just bellow the 90s, where as before one of my cards was sitting at 100 constantly.

Putting the S9 back to this firmware does help the fans issue!!
