Is this a Mac pro 65lb tower?
Is the noise coming from the sound system (can you hear it with headphones) or from the chassis itself?Mac Pro (Early 2009), Mac OS X (10.6.8), & Server, PPC, & AppleTalk Printers

This sound is coming from the back of my monitor...I don't use headphones. I can hear it when the computer is 1st turned on. Sometimes it will go away and sometimes it will not...don't know if that helps you any...thanks!
Humming from the case is common and has been an issue - and can be annoying - humm from PSU, disk drives, the case itself - clash of different vibrations that can get started.
There are 'washers' on the side door even to help absorb.
But first I can recall of a monitor doing something -
3-4 yrs for a workstation is not fossil - for a laptop, yes. Even an iMac will outgrow with time.
So probably 2008 3,1 model 2.8 4- or 8-core.
People use washers on the drive sleds. Look for dust. Can be from video card and most definitely was with the OEM stock ATI 2600XT. Something that is overdue to get replaced with 5770 or something else.
I had mine on coffee table with mat underneath laying on its side, only way to get rid of the humm from the case. Now it is fine again and almost dead quiet: SSD and different disk drives and a quiet gpu.
Thanks! Will call my local MAC repair place and see what they can do abt video card. And, could very well be dust as well. I just wiped some dust from the back "vent" area after reading last post. So, I bet there is some in the unit. Glad to know my desktop is not a fossil. LOL!! I just figured since everything gets upgraded so fast, 3 or 4 years is old...I appreciate the feedback!!
I would skip your MAC repair shop.
Want gpu, get the ATI 5770 from Amz, B&H, Apple.
Want FBDIMMs: Amazon 2.x2GB (FBDIMMs die and don't last and these are 667 work and $40) RAM can have side effects.
Safe, popular, does a great job - may want to take it out in the garage
Metro Vacuum ED500 DataVac 500-Watt 0.75-HP Electric Duster 120-Volt2x2GB FBDIMM DDR2 667MHz @ $39
Would never be w/o this:
