How noisy is a Mac Pro?

[Maui]

My Mac Pro is silent, even under heavy load. It is quieter then the MacBook Pro I used to own.

Same here.

I went from 2 big Dell's to a Mac Pro, and I still can't believe how much quieter my den is.

PowerBook Pro Humming?

Sound reassuring, thanks for all the answers. I can cope with hard drive noise, it was the constant humming of the fans I was afraid of.

Snorby.

I have the same problem, I left it back to the dealer twice, he can do nothing with it.
I was 3 Days outside the warranty. Does any one know a cure for it, it is driving me mad...

Mine just started giving me a tiny "power buzz" which I think is coming from the power supply.

Nothing major, but a little annoying on such a silent system.

Mine is eerily silent. I have to look at the blue LED to be able to tell if it's on or off.

Very quiet except when burning CD / DVD's ..

Tonight I successfully ran a GeForce 8800GTS in the machine and it was still very quiet. It's great.

In Mac OS X or just in Windows?

The MP is an incredibly quiet computer. I had a G5 1.8 previously and it was much, much louder. However, as previously mentioned by other posts the DVD/CD Rom (Optiarc model - came with the MP) is ridiculously noisy and clunky, as is the loading tray mechanism. The Hard drives also are noisy but only because the machine itself is almost inaudible. I use it in a recording studio and it's fantastic, almost no mic bleed! Anyone remember the 'wind tunnel' G4's....

My Mac Pro is silent as heck, the only thing that makes a noise is the HDD. People who updated to the newest firmware know just HOW noisy the Mac Pro COULD be but its amazing how silent it actually is.

All my fans spin at below 700RPM and they can never be heard.

Yeah, even my MacBook Pro is noisier when under load.
