    One is in a psu as it is brilliant horizontally - no bearing noise whatsoever. The other is a case fan in vertical position, very slight bearing noise.

    Wanted to try some other quiet fans.

    Just to let you know, I'm sure that northQ fan pushes out alot more air than 17cfm, i think it's more like 30cfm.

    Thank you for reminding me - I believe it's around 38cfm.

    Thank you for the confirmation on the NorthQ - I had 2 delivered this morning.
    A bit of research showed that a) 17cfm was probably incorrect and b) 17cfm would be useless!
    It's usually possible to get an idea of output from RPM and the blades; the NorthQ looked attractive on specs. (I wonder if it's not coincidence that cfm and db are the same figure) and at 17db doesn't really need undervolting.
    BTW, the FN121 have very good noise/pressure figures.

    Any bearing noise from the NorthQ fans?
