Fair enough, but the extra elevation is just an extra 1cm and the thing is near the floor behind a rather massive 5 feet wide enclosed MDF TV cabinet with a 55" TV sitting on it. If that small diff was the cause, I must say I'm mighty impressed by my hearing.The NAS is quite quiet BTW (not totally so if you go close to it of course, but I would probably say the noise level is much like a laptop sitting idle)
Cheers.

Ok, although I do not see how a 1cm addition to height did much to improve the cooling, which is where this all started.
But, yeah, as Tony and I both suggested, I would move the NAS out of the room. It might reveal whether this height and footing change still causes a difference. If it still does, you can cross the NAS in the room off the list and focus elsewhere. Either way, it will provide useful information to you as part of an open-minded inquiry.
you won't hear low frequency sound or vibration, but they may well be there, especially if you have floor boards that 'amplify' such effects.
Tony Lauck's suggestion of moving the NAS out is a sound first step.
There is no point in theorising too much but if want to find out the cause, systematic action is required.
Agreed. Those of us replying in this thread were forced to theorize because we didn't have hands on access to the problem. It seems the time for action has come. Move the NAS out of the room.For years I had my entire system out of the room, except for the speakers and speaker wires. The equipment rack was on a floor below, with rack on a concrete slab. Sonically, this worked well, but at times it was aerobically challenging.

Thanks for the suggestion.
Now that the Nas is back to how it was situated before it all began, the same fine sound is back and temperature seems alright, I guess I'll leave it for now and enjoy the music.
I would not worry about the CPU temperature in any event. I would worry about the disk drive temperature(s) however, because they affect the lifetime of the data, and while I would hope that the RAID configuration would save the data in the event of a drive failure, I would definitely not count on it.

Thanks.
CPU temp is now at mid to high 40 degrees celsius, was at about 60 (which is still not dangerously high) at its "bad" times.
HDD temp had been at high 30s all along and is rather stable.
So the issue had nothing to do with microphonics, which is what most folks would expect with a NAS. Good to know you have your nice sound back.
Another statement aimed at self justification for making absurd and incorrect posts on microphonics.
