Yeah, I know of bigfoot computers, and I just noticed in addition to vantec steath power supplies, they also categorize high and ultra speed panaflos under quiet for some bizare reason.
Wow, Tigr, did you read the rest of this thread? You want me to "upgrade" to Panaflo 80mm fans? So I'll take out my Zalman 21db fans and replace them with Panaflos that produce 21db. Something's wrong with your math there.
I thought you said you had vantec's? Panaflo L1A's are quiter than vantec stealths. They do move a bit less air though. However, from what I know, vantec stealths undervolt alright.
A sturdy stainless steel case would weigh over a hundred pounds fully equipped. I don't need that, I paid a premium to have a lightweight case. As for resonance, I held the sides of the case with my hands to see if there was any noticable difference in sound... and there was none. 99.9% of the noise in this case is coming from fans and air movement.
It's very hard to believe that vantec stealth fans are producing less noise than WD hard drives. Maybe you should check what effect turning off one or a few of the fans has compared to one/a few WD hard drives, or try one of each in another computer.
If it is fan noise, it should be the fans in your power supply(hard to check how it would sound without those three power supply fans though). You could perhaps take some of those vantec stealth fans and put them in your PSU.
As for the hard drives... wow. That's quite the comment you made there! I have 3 other WD drives (including a 36gb 10k rpm Raptor) in another workstation box which is relatively silent. These drives produce NO NOISE.
That's impossible for any hard drives, let alone a WD one, if you mean no noise over the other stuff, those have to be quite loud PCs.
I appreciate your suggestion, but I'm not interested in spending several hundred dollars for zero improvement in sound emission.
You don't neccessarily have to replace them, are you sure you need all of them? Perhaps you could use an external backup drive more? If so, you could check which of those is the loudest and put it in an external enclosure.
The only possible improvement I can see wrt to the HD situation is to use rubber grommets on the hard drive mounts.
What about suspension? You might not have room for it for all the drives, but maybe it would help a lot if there are one or two particularly loud drives.
