But how can I handle this? If I disconnect the fans, there won't be any effective cooling. This also doesn't seem like a fan at all. The case fans run at a steady speed, so if they're hitting something, it should be clear. If it's a fan, then it might be the big Noctua CPU fan or the GPU fan, but it doesn't sound like a fan—it just makes that strange noise resembling an HDD.
You're likely dealing with more than one enthusiast. Leave the side panel off and just keep an eye on your temperatures—you might be surprised. Many systems have settings that let fans shut down completely for a reason. Temporarily taking a fan out of the loop won't usually damage your PC. Keep an ear to the ground and watch the fans. Your system probably isn't fully controlled by the motherboard; most do adjust speed, whether using PWM or DC. If a fan is faulty, its blades might move slightly inside the case, possibly touching nearby wires. A baseball card lodged in the spokes could be the culprit. You'll need to test each component one at a time. Finding the source might feel like guessing by sound alone—hoping someone can spot it from a clip would be lucky. We can suggest some tests, but if you prefer not to try, the noise will remain.
This appears to be a fan (bearing), unsure about the type of HDDs you used—it seems unrelated to a typical HDD. You can replace or eliminate the fans one at a time, or alternatively lower their speed.
I have a fractal R6 unit. Do you know any trustworthy programs to adjust each fan speed to zero individually? Probably the most straightforward approach—though it sounds like a lot of effort. I think it should be possible to locate this easily. Speaking of adjustments, I recall setting some fan speeds based on temperature curves in the BIOS because the Noctua was too loud, and I discovered an optimal range where it activated above a certain point. I’m not sure about other fans, but the temperatures look normal.
I identified the problem. The PCH_FAN was mentioned in the UEFI, and it seems many users experience this issue with the Aorus Pro x570. I adjusted the settings to silent mode, and it’s now quiet. Testing confirmed the temperature remains consistent across different modes—Balanced and Performance. It’s currently silent, and the fan isn’t running. I’m concerned about overheating, especially since I have a noctua dh-15. I’m unsure if this setup will keep the PCH cool without a dedicated fan. It’s surprising I purchased this, as there are numerous threads with complaints about it. There’s always something you might have missed when buying.
