I have an NF A15 (i got it because it was quieter than the one you have)
Other than that, what your stating is strange since the parts they use are to make it extremely quite!
They should not make that much noise, "upside down" is "no such thing" because fans are made to blow in or out you get me? depending on what you need it for!
Have you secured the fans correctly?? (I am guessing you have though)
Rasping should NOT occur with this brand =/ and it would need an RMA (but have you tried fliping it around to see if it still makes rasping noise?)
if you have changed direction & orientation of fans and it still causes the same thing to happen then sadly an RMA may be needed!
