Service Action to Prevent PSU Failures in ReadyNAS NV/NV+

Thanks for your reply. If you follow the fan reversal instructions, you will notice a picture of the fan before and after the flip. The label on the fan is visible before, and not after. Looking at my fan, the arrow indicating air-flow direction is towards the label side. This means that the default fan setup, with the label facing backwards, was pulling air out of the back of the unit. With the new setup, it "should" be pushing air into the back of the unit, where it would blow out of the front and sides. So I took a look at the front, and that black filter screen seems pretty impervious. Heck, I took the whole front screen off, but noticed little difference. Only when I took the sides off did I notice much of a difference. Hard drive temps of 33-37, board temp of 30. Air is being blown out of the sides, most notable the top side vents, toward the back. I did a recalibrate, and the fan dropped to 1700rpm. I do notice that the air-holes on the side panels to not perfectcly align with the spot where the air is being blown out. ALso I am not sure why most air is coming out of the rear sides versus front and/or front sides. Very frustrating!
