After updating from v38 to v07, the product is making a lot of coil whine noise when the system is not under load.
There are people in other communities complaining of the same issue.
I tried rolling back to the previous version but it was not possible due to verify fail error.
Is there any other way to roll back to the old version or can you provide me with a firmware that fixes the issue?
Thank you.

    Hi there .
    V07 is not reversible, i am sorry
    was it from the fan ?
    1.You can also try Software : SpeedFan  to optimize the fan .

        The noise is not coming from a cooling fan.
        It’s a crackling noise from electronic components (usually from choke coils), similar to the noise of an old hard disk.
