has anyone expirience with the awful whining noise of the S9i miners?

i have some as an upgrade, but at a certain point they generate a sound that goes through the bones!
I had one connected to silencing hose at inlet and outlet, but the noise that came from the machine itself was horrible and pain to the ears... When the fans speeded up and or down a bit, it was as good as gone...
bad thing is that it seems to be right at operating speed.

anyone experience this as well?

Yes some of them do this, its infuriating! A well located bit of duct tape near one of the fan blades tends to eliminate the odd harmonic
