Hello all, recently I've built my first pc. It's working great, no issues and thankfully very quiet. Although there is one problem.. A rising and falling tone, similar to a sinusoidal pattern that occurs very sporadically (i cannot find any specific action that triggers it). I have adjusted fan speed/sync in the bios, which didnt help one bit, persistent with or without dedicated GPU inserted, AiO doesnt seem to be the culprit either. The only options remaining would be the PSU (quiet coil whine??) or capacitators adjusting the power flow. Perhaps any of you guys had a similar issue or other ideas for me. My next steps will be to try a different power outlet, then monitoring PSU voltage, then different PSU, then ?? Specs: Ryzen 5 7600x3d, B650 Aorus Elite ax v2 , crucial sata 2TB, crucial M.2 2TB, Kingston Fury Beast 64GB DDR5-6000, bequiet Pure Power 1000W (non-modular), LF III 360, arctic p12/p14, rtx 4060 (temporarily) in an H6 Flow. Win 11 64bit. BIOS AMI F13. SMBIOS 3.7. (please redirect me to an existing thread, as I haven't found one specific to my problem) Thanks in advance
The sound disappears entirely when you power down the device and disconnect the power supply. That’s why it helps for people with misophonia and hyperacusis who find certain noises distressing.
Noted! I'm checking if it's the PC or PSU that's the problem. The LED light was a bit of a distraction until I figured it out. First, try turning off the PC while keeping the PSU on—power through the PSU can still cause whine in some units. Then, unplug the PSU entirely and see if the issue persists.
Based on what you understand, connecting speakers behind the motherboard can sometimes produce audible feedback. It might be the GPU drawing power and causing issues, or it could relate to older setups where the sound came from a spinning HDD indicating hardware problems like misalignment. Other possibilities include microphone noise entering through speakers due to poor grounding or using a splitter incorrectly.
Turned off the PC at the last occurrence and could still hear it for 1-2 seconds after shutdown, then silence followed. (Power supply unit was active). Now I’m less certain it’s the PSU since I heard it closely without using the side panel. It was more apparent on the motherboard side than where the PSU is mounted. Switching outlets didn’t help. It could be the capacitors on the motherboard (hard to fix) or another component interaction, which would be trickier to identify.
I attempted to disconnect all devices including speakers, monitors individually, USB peripherals, Wi-Fi antenna, and Ethernet cable. It wasn't the GPU I tested, as I checked with and without a dedicated one. The system doesn't have an HDD. Occasionally it happens during gaming, while working, or when nothing is active (like while writing this).
