Same exact form factor.
Air Flow 9.2 CFM
9500 RPM
Noise 42 dB(A)
Note the 18dB greater noise (that's a HUGE difference). Even with bad
bearings in the original fan, it is probably considerably quieter (by
10dB or more) than the proposed replacement. On the other hand, the
replacement moves 28% more air, which may be a good thing.
Best regards,
