However, stopping the fans completely isn't a solid conclusion since they're still active. You'd need to disable them temporarily using fan control, perhaps for a short period, rather than shutting them down entirely. This approach is safe even at 300rpm, which runs quietly and won't damage the system.
It looks like you’re addressing a tech issue. The AIO and its back fan were both disconnected, which caused the same noise problem. I also swapped out the power supply while doing it. The motherboard seems to be the main culprit—unless I overlooked something, I’ll wait a few weeks and consider a return if needed. I might test USB Linux later.
Greetings, I'm facing the same issue with the same motherboard. I've submitted a support ticket on Asus hoping they can resolve it in the upcoming BIOS update.
Hey @Suban228, nice to hear from you! I’m happy to hear you’re not alone with this problem. It sounds like you’ve got a similar issue with both units—one is getting a refund while the other is being sent back for testing. Did you check the box for the manufacturing date? And what model CPU are you using?
Production date reads 2022-11 and it matches model 7600X. Recent updates from ASUS Support clarify the situation: the described noise isn't a software glitch but a physical occurrence tied to certain conditions. This whistling or squeaking typically comes from inductors—chokes—within the CPU power section, video interface, expansion cards, or power supply unit. Even if you swap components like the PSU or graphics card, the issue can persist. The sound isn't a fault; it's a natural result of inductance effects, especially noticeable under specific system settings or operating modes.
First, verify if the chokes on your board are making noise. If they are, adjusting CPU power-saving settings in BIOS (Advanced → CPU Configuration → Power Management) might help. Modifying parameters such as C1 State, C3 Report, and C6 Report can influence how the processor handles high-frequency vibrations, potentially reducing or eliminating the sound.
Another option is replacing the power supply unit with a different model. This won't fix the problem if the chokes are still present, but it may resolve the issue. If the noise remains clear and stands out against background fan hum, it’s likely a design characteristic of the power supply itself.
If these steps don’t resolve the matter or you feel the sound is disruptive, reach out to the board manufacturer for a return merchandise authorization (RMA) process.
