My fan sensor was bad on my last P5Q Deluxe that I sent back. This one seems to be a good one for sensors. The engineer said that we need to set the margin enhancement option to performance for our 9450s but, he is still getting issues at the same time so,, not to stable IMO. I could have sworn that I set mine to that and I still had the issue. Maybe not , maybe I'm getting old and forgeting things.
