Anyone hear similar sound while charging?

Plugged in my truck when i got home from work. Sounds like a mix between a fan operating at high rpm and high pitched electrical hum.
No error or notifications, charging at 11.3kw 48A/233v

Was the pack cold?
My Beast will make noise at the drive unit area while charging sometimes. I think it is using the drive unit to heat up the pack.
Front and rear noises from different days:

Mongo thank you for sharing these. I've noticed these noises on my Beast but never heard it on my AWD. At least the hissing sound. It's been concerning, but as it goes, "if it ain't broke...". So you sharing just added a level of comfort to my day lol

Yeah. Had a blue snowflake. My drive was only 10 minutes. Makes sense that the truck was warming up the battery for charging. It was just louder than i had heard before.

my AWD makes this loud fan noise when at a supercharger recently, I had been arriving to charge without getting my Truck ready for charging. I just figured it was how the vehicle makes this sound while charging, but yea other times when I do a GPS heading to a Supercharger it says "Getting ready for the charger" or something like that, and maybe it doesn't make that noise in those situations. Glad to read this discussion.

Loud fan sounds more like cooling mode.
The noise would be different while driving to the Supercharger as the lossy waveform is a shift in the normal inverter output versus the only thing going on.
Old school analogy, shifting the timing and adding throttle resulting in the same power but more fuel burned

I've heard similar from my MY on very cold days. Shiver me motors...
