Computer whining (~16khz noise coming from somewhere in the case)
My computer makes a very annoying high pitched noise under medium loads. I have been chasing this problem for a few days now and would appreciate any input you might have. System details: OS: Lubuntu 21.10; CPU: AMD FX-8350; Mobo: Asrock FX990 Ext.4; GPU1 MSI Geforce GTX1060 6GB; GPU2 ATI Radeon HD7750. Will elaborate upon request. See the constant 16khz tone on the far right? that's my problem:![Spectrograph from Spectroid app on Android](https://powerusers.codidact.com/uploads/iYsyX55HWGD5xpKvqRnLp6rm) Spectrograph from Spectroid app on Android The noise usually appears after playing KSP for about 30min-1hr, with some other stuff (usually a youtube video) going in the other monitor. Things that I think are **NOT** the cause: 1. My audio setup. I've turned off the speakers, unplugged them, moved wires around, all with no discernible effect. 2. The CPU fan. I've gone into BIOS and throttled it up and down manually. I can see the RPM readout changing but the noise does not appear, even at max RPM. 3. The GPU1 fans. I went into Nvidia Xserver settings and throttled them up and down without reproducing the noise. I can't say I've encountered a problem that makes using my PC physically painful before. Please let me know if you have more troubleshooting ideas.
