Whirring sound?

Their mass is probably so low that damping the outside of the, much higher mass, chassis in which these lower mass ferrites vibrate won't make much of a difference. I think these ferrites need to be dampened directly (if possible).

exactly! dampening doesn't change a thing, I tried it
