no overclocking. The noise happened the very first time I turned the computer on. Since then I've only adjusted fan and storage settings. I installed everything on my HDD and I'm not going to overclock until the system is running properly at stock speeds.
here is a video. I filtered out the low pitch noises below 5kHz because my neighbor was mowing and the rest appears to be background noise. The noise isn't very loud, but it is annoying. The video was taken with the computer off (PSU powered on) because otherwise all you can hear is fans on the recording. You can hear the squeal when the PC and fans are on, but the camera just doesn't pick it up. I don't have better audio recording equipment.
