Coolermaster sf19 fan noise question

[blablacentral]

anyone have this laptop cooler and notice that at high all you hear is wind noise which is normal but at like 50-60% you hear this loud wat wat wat wat wat sound with a vibration and if you turn it down a little more it gets quieter untill its berable at like 25-30% fanspeed.

or is this just my cooler.

how long have you had this cooler?

I mean chances are it's just a slight misalignment of the rotation axis, very typical in huge axial fans

if you've had it for over 2 years, I think 50% of such fans develop noise artifacts due to misalignment

its new i got it like 3 days ago.

its just weird that high and low speeds its fine its them in between speeds that make the noise.

well, the centripetal force at high speeds probably forces it to return to proper axis. I'd say since it's brand new, call up their customer support and express your concerns. They'll tell you if it's normal or not (if not then they obviously will have to replace it). I think that'll give you a peace of mind.
