X570-I incredibly loud coil whine

[Chance666]

Im having an issue with my X570-I Motherboard where it has what i can only identify as incredibly loud coil whine. At first i thought it was the little fan on the rear IO side of the MB but it persisted even after i disconnected the fan. I've already tweaked some bios settings that were recommended in other posts like disabling c-states and setting vcore to manual but that didn't help basically at all.

My PC sounds like it has an old optical drive in it, its driving me crazy. Is there anything else i can do about this?

Hello @Chance666 

Thank you for reaching out, and we’re glad you were able to identify the issue.
Since it's unclear where the removed fan was connected on the motherboard, we recommend monitoring system temperatures to avoid any potential heat buildup or performance impact from the fan removal.

If needed, you might consider testing another fan or using software such as Armoury Crate to control fan speeds and monitor system temperatures. For more details, please refer to the [Motherboard] Armoury Crate - Introduction. 

Thank you.
