Weird Sound coming from MCU

I’ve had my 2015 S for a little over a year now and this is the first time I experienced this....I got into my car after lunch and heard a really weird sound that sounded like a bad fan while I was driving. I turned off my climate control and it remained...I happened to be close to my Tesla Service center so I called them to see if I can swing by and when I was on the call via Bluetooth, the sound disappeared. Tesla told me to reboot the MCU as they’ve seen this issue before and sure enough that fixed it. Obviously software related.

Anyone else ever have this happen? My wife claimed it happened once when she was driving. (Of course I hear about it now!)
