Replacement fan for Ultra 6

If you have visual access to the back of the NAS, you may be able to confirm it yourself: That fan will be mounted with its label facing out, so look through the rear-panel screen and see if you can read enough of its model number to tell whether it matches the model number I posted. If you can shut down the NAS, even better: You can open it up and see exactly what model number the fan is. And while you're in there, you can blow out what's likely to be a huge amount of dust inside the chassis. If there's a lot of dust on the fan itself, it might just need cleaning, not replacement (but make sure when you blow out the dust not to spin the fan too quickly; over-revving a fan with compressed air is a quick way to kill its bearing).

I have a feeling that over-revving is what might have caused the bearings to die yes :? I'll shut it down and see if I can get the serial off the fan later today, but I think I tried to no avail earlier. Thanks.
