Is it possible to avoid certain RPM in auto mode

[F1reDiamond]

Every fan together with either the radiator or case attached, will have certain frequency to resonate, which could boost the noise or make unpleasant shriek sound (albeit very faint, yet still possible to pick up in a quiet room). It’s easy to avoid in curves since you can make very steep curve at certain RPM, yet in auto mode, you can’t adjust.
Although it is possible to avoid running the fan at certain RPM by adjusting the idle RPM to avoid this, still hoping there could be a remedy for this.
