Back in the early days of deep learning I did a fair amount of my performance debugging by listening to the coil whine during training, (this was when a GTX 1080 was hot stuff.) Fun to see this come back!
My amd ryzen 9 9800x3d with ASUS b850 motherboard whines like a mofo. I used to run ai tooling front ends that launched workloads into the ryzen9 backend. Randomly I would hear it whining and could guess the workload based on the whine.
Reminds me of my Intel 486dx2 66mhx systems or pentium 200mhz cpus which would generate cool whine on 97.1 through 100.3 on my radio in my room.
