The 4870 is the loudest part of the system I've managed to build. (Also a Sapphire, using ATI's reference design, but with increased memory).
It's not too bad, but it's certainly not "quiet" when loaded.
Got a tip for us?

New 2.26 (2009) Mac Pro Humming Noise

I have the same humming noise. It's a deep and low frequency hum. It get's annoying if everything else is quiet in the room.
I did try to isolate it but haven't been successful. It's not the hard drives as I've booted with all the drives out. Doesn't sound like the GT120 either. Could be one of the heatsink fans or the PSU.
Anyone else been able to isolate it yet?

Its most likely the GT120, just stop the fan for a second or two by putting your finger on it. However, in my case the fan called "BOOSTA" inside the Xeons heatsink makes an oscillating noise that is going on my nerves... AASP said thats normal and I'm just too sensitive
I just bought a refurb Mac pro 2.8. I get the "humming" sound also....humm...humm...humm. VERY annoying.

According to that thread it's the extra hard drives. Sure enough I took out my 2nd drive and no noise. But it's really stupid to buy a machine like this but you can't install extra drives in without this problem. I'll be calling Apple soon and see what they say.

You mean open it while the machine is on? Is that safe?
I want to eliminate the sound, not minimize it.
I shall reiterate that the hum will be down to either:
HD resonance, for which you should seek new ways of dampening it (although it is only cosmetic in this case)
or (as i have had)
a faulty PSU. I had three of these last year, and they were all confirmed faults by apple technical support. Was eventually fixed by machine replacement alongside considerable gestures of good will to make up for lost time etc
If its oscilating, and you have ruled out it being the hard drive, (and moreover if the noise can be heard most prominently from the top, rear of the machine) then call applecare

I don't think I should have to resort to anything like that. I can feel the vibration in the exact spot where the 2nd HDD is located.
I'll be calling Apple after sales support on monday and see what they say. At the moment i'm inclined to send it back for a refund or swap it over for an imac.
So far seems like the 2009 mac pros have problems with bad PSU or fans with buzzing noises. I think I'll wait a few more months for everything to be ironed out first.
That's not true. I've asked a number of guys who purchased a new Mac Pro over at a german mac forum and noone has that issue.
yea but I'm verrrry sensitive to noise and if these people hear it, I'll definitely hear it as well.
my ear drum hurts. The buzzing is killing me. Although i do have sensitive hearing. I hear subwoofers when they are just plugged and my screen .
This is the worst sound i've heard so far. My brother and my flatmate also hear this sound though. Too much buzzzzzz.
Anyone sent a complaint to apple?
thanks

I called apple this morning to organise a return and refund. They agreed so i'm happy.
But I've lost faith in tower macs. My G5 cost me $3.5K AUD and lasted less than 4 years. I can't get anyone to properly diagnose the problem with it. And now this mac pro.... it's simply not good enough.

Glad to see that you got a refund, as i said this is a problem that apple will replace a machine for if you call them.
I myself have been increasingly disappointed with apple's recent quality control, just doesn't seem up to the standards that it used to be. I suppose with market comfort comes a relaxing of standards
4870 fan noise
I am also very sensitive to noise and a little disappointed by the noise coming from my new MacPro Octad 2.66. So I opened it and removed parts to identify what noises originate from what parts. Removed the hard disks, the PCI-Fan (easily removable by 2 screws), and the entire graphics card (4870).
My findings: The most annoying sound is coming from the 4870. It is not loud, but the "brrrrrrr" sound is somewhat annoying. I think I am going to try one of the alternative coolers for the 4870. However, it is not that easy because there seem to be heat problems with the voltage regulators once the original cooler is removed. But I will investigate further.

I got an exchange today, after 11 days of "considering" oftaking it back I finally did it. The new MP makes exactly the same noise (old one was serial CK9090xxxxxx, new one as well)
It has nothing to do with the Nehalem processor. It has to do with the fact that Apple used a cheap motherboard that had low-grade components in it. The sound usually originates from the mosfets around the CPU socket.
With low-grade components, when they go into an energy-saving state, they resonate which causes a high-pitched electronic frequency noise. Apple is at fault here.
