Mine did that same Hannibal Lecter F-F-F-F-F sound to me too. Stock everything except a BMS Stage 1. It started with there having been no changes any time recently and it went away on its own after only doing it in these same kinds of conditions for a couple of weeks. It's been over a year since it last did it.
