Hi, thank you. I think it is even wonderful that someone alludes to knowing that they are not directly answering the question :p.
These days too many people even lack such awareness.
And then what often happens is that you have to fight them to no end to get the answer to the question you've asked...
Yes I've turned off all the fans -- simply by stopping them.
I have two computers in my home right now. The other one I turned off to see what the difference would be. The other one has a 7200 rpm notebook drive that would create a huge hum (high pitched too) until I just found the nearest (old, jikes) piece of elastic cord -- from some A4 binder lol) -- and created a bed out of that and as long as it doesn't touch anything hard the hum is now gone.
From that case.
Yesterday I was looking at ordering some elastic cord and some cable fasteners (like these ones:
Maybe I'm not answering your question either :p.
I never noticed the hum before because the case was always open
. I have not yet done anything "pressure point" wise but I don't think it will make a difference, every case I have basically does that thing that it only starts to resonate when closed.
I know I probably want to reduce the speed of one of the fans but it is already at ... well I have it stopped. But it is at something like 800. The GPU fan spins at some 860 and even though it makes a bit of a rattling sound that's not something you can hear outside of the case.
No it is the low vibration sound -- the bass -- that carries far.
And it is definitely the result of the hard drives and the chambre, I think.
It is something I can feel in my belly and that's why I don't like it.
The only fan that remains -- apart from the GPU -- at this point is the big Antec fan (200mm). The trouble with that one is that it takes a lot of juice to get going (start voltage) but not so much to keep going. Regardless it is not "heavy" enough to produce such a low hum that I can feel.
I just changed one of the grommets as it was sitting on the wrong side (thin side up) in the top part of the cambre (hard drive cage) and the sound is a little bit better now.
Seeing the holes in the chambre (cage) it is fairly easy to suspend 2 or even 3 drives in there (vertically).
Horizontally probably max 2 or 3 but this would mean a lot of crossing wire (cord).
In the lower chambre, typically you'll only be able to suspend one. Or two in a twin mount, but I think the disks were getting electromagnetic interference, apart from vibration.
