Prepare your new PC using a Fractal Design Define 7 XL, 3 Fractal dynamic X2 GP - 14 case fans (2 front, 1 back) and ROG Strix B760 - F Gaming Wifi Motherboard. Equipped with an RTX 4080, Palit Gaming Pro and i7-13700K. I’m experiencing a strange resonating buzz from my PC at regular intervals—lasting 10 to 30 seconds, then disappearing completely before returning. The noise intensifies under load, though the timing between bursts remains consistent. It becomes noticeably louder when the system is stressed. The sound can be heard through the case and headset, becoming increasingly irritating. It started a few days ago. My build is only about four months old. I thought it might be a faulty fan or that all fans are spinning together, but I read online that this could explain the issue. Also, the buzz changes when I remove the left panel from my case—it gets quieter, suggesting resonance in that area. After testing extensively, here’s what I found:

- Disconnected everything from the Fractal Hub and connected all fans to the motherboard. The humming persisted, but the chassis fans appeared in BIOS settings when they weren’t active—no longer present while connected.
- Checked for loose wires or resonating cables, but none were found.
- Moved a heavy case around in my room; it didn’t resolve the problem.
- Ran Fan Control software through each fan at various speeds (30% to full), and with no change in noise.
- Increased CPU and chassis fan speeds gradually, still without any sound.
- Played a game under load, then the buzz resumed after a few minutes. I captured screenshots showing the low hum at different RPMs: [link1](https://imgur.com/jIzIgnD) and [link2](https://imgur.com/RERJtHf). The second image shows it louder and more irregular.

It’s not just a typical fan noise; it resembles a distant engine getting louder, then fading as distance increases, with a steady pattern. I’m unsure what exactly is causing this. Please advise if there’s any truth to these observations.
