Yes, that high pitched whine sounds soo familiar..![]()
And the ear bleeding that comes after...
Makes me question how it's server grade and rated for 24/7 when it sounds like it's about to have a nuclear meltdown at all times haha![]()
I sure hope those bearings/sleeves or whatever they use in them are durable enough; AKA are made of diamonds. Seems like chance of failure would be high with something like a 12x12 grid of these too.
But you know they are serious business when they have a chrome fan grill over them.![]()
Yeah, part of the noise is the fact they use ball bearings instead of sleeve. It's more cost efficient to manufacture a ball bearing with a long life expectancy than a sleeve bearing of equal quality. The majority of Delta's stuff is ball, with a few sleeve bearing fans at the low end (DSB series).
