Thinking of Getting One.

Never seen one in action but they look a work of art

Get anyone tell me if they are noisey especially when Idling as I plan to have it in my Bedroom.

One more question guys I have a 46" 1080p TV & a 24 inch monitor, both are 1920x1080.

I plan to have dual display support I hear the New MBP's pass Audio through the Display Port do the current GT120 & 4870's do this?

Iask because I have a digital Reciever Too

As long as you don't have it sitting on your desk at ear level it is silent, otherwise you will hear the fans.

My Mac Pro sits on my desk next to my monitor. I never hear it.

Not sure about the GT120, but the 4870 should be able to handle two 1920x1080 displays fine.

the gt120 will drive 2 screens at 1920HD resolution too ;)

Mine is a bit noisy with the 4 10,000RPM drives inside… the problem is when it's seeking; if you stick to regular 7200RPM drives, the computer is pretty much silent.

There's at least one base which the Mac Pro may not cover that easily - portability. :p

But yep, the Mac Pro is pretty much a great machine.

p.s. cost may be another base that doesn't quite cut it yet.

Mac Pro is super silent machine! I am running video games through win7 for 6 hours everyday. at the beginning I was wondering when I would hear the fan noise; so I became suspicious and I went to the repair shop and they told me that there is no issue. Right now my system has completed one year and fan noise is not existed at all expect when I switch on / restart my system.

Very quiet. The difference between this and my dual G5 is dramatic (and the G5 was a lot quieter than the G4 which sounded like a jet taking off!)

From what I remember, only the MDD PowerMac G4s were noisy. Other PwerMac G4s were quiet. Early G4s were even passively cooled. G5s ran hot. Apple even had to resort to water cooling on some models.

Very quiet. The only noise that arises is when you use the DVD/CD drive... (and then it's very noisy)...

I can't confirm this. I've got 4 7200RPM drives in my Pro (2 WD Blacks and 2 RE3) and it is very noisy.
The fans are indeed quite silent (you can hear it though!), but with 7200RMP drives in it, the machine is everything but quiet!

I had it once next to my displays on the desk, definitely too noisy to work.

Got the 2009 octad model with 4870.

I think it depends on the user's ability to hear, perception, the
positioning of the machine, the reflectivity/absorption of surrounding
surfaces, and other ambient noise. Unless measurements are being made
scientifically, observations on noise level are difficult to interpret at
best.

Having said all that, in this environment and using my ears, I can quite
easily hear a Mac Pro. And, as you say, the drives are the cause. I've
listened to several different Mac Pros, and in each case the drives were
quite audible. Again, to me and my ears :)

But being audible and being noisy are not the same thing, unless you must
work in extreme silence. While I can hear Mac Pros, I do not find them
disconcertingly loud.

Mine is very quiet.

I've got 3 HDDs, 1 SSD, 1 GT120 and the Radeon 4870.

It sits on my desk, and it's quiet. There is obviously some noise, but in comparison to every other computer in the house it's the quietest. As others have mentioned, about all the noise comes out of the HDs, but even then they're not too bad either. Optical drive is pretty noisy when you first insert the disc, but $30 can buy a quieter model if it really bothers you.

Noise is a very subjective thing.

My boot drive is an Solid State Disk and I can easily hear when my RAID-5 scratch drive powers up when I access the drive.

They are the noisiest components in my Mac Pro (early 2008), which makes it very silent.

I have a 2.66 Xeon Mac pro and that thing is completely silent, even running under a load. I have only heard the fans kick up a couple of times. Great computer, well worth the $$

Similar to the above comments ...
- ODD is extremely noisy when in use
- The fans are loud on boot and when awaken from sleep.

The brands of ODDs I've encountered were Pioneer and Sony. I cannot recall the exact model though.

I can always hear the fans, even when it's under my desk. However, the room I'm in is very quiet, which may explain the discrepancy between what I'm saying and what others are. I have a mid-2009 MacPro, btw. The hard drive is audible when it's seeking or writing. The fans get a little louder when playing World of Warcraft, but they never get irritatingly loud (which is a lot different than my MBP). However, unlike my MBP, my MacPro's fans are never silent.

Then I should hear the drive of my 24" iMac as well.

I'm very much into silent computing, and I would definitely notice the drive making a noise as it's right in front of me, behind the screen. I can hear the scratching when there is read or write activity, but that's really a low sound.

Silent? No. Quiet? Yes.

As others have mentioned, the Mac Pro is quieter than the average PC. That said, the optical and hard drives can create noise and vibrations, especially if you have more than the stock configuration of one optical drive and one hard drive. In my Mac Pro, the vibrations can become noisy. I traced the main noise to vibrations in the side door; I happened to have a piece of Dynamat from an old PC, so I attached the Dynamat to the inside of the side door, replaced the door, which reduced the noise to nearly nothing.

And as others have noted, whether you hear the noise depends on your sensitivity, on other noises in your environment, and on your distance from the Mac Pro. In my case, my office is very quiet (unless the dog is snoring - :D ), and the Mac Pro is very close to where I sit.

Your mileage may vary.

I guess what's meant is processing power. Anyway, 980W?
I can hardly push my octad Pro with two graphics cards (4870 and 120) and six hard drives over 320W.


Storage - 4 bays, hardly it`s a "storage"


Maximum internal storage capacity of a Mac Pro is 20TB+. Should be more than enough for the average home user without a dedicated storage server.

ATI 5870 works just well in Windows. Personally I'd consider it tho be high end.

That's just nonsense. You don't have to use to use Apple parts for anything. PC graphics cards are flashable, DVD/BluRay drives are equal for Mac and PC and so are hard drives, RAM and CPUs. And most premium RAID cards come with Mac drivers, too.


Movies - my phone can show movies too


Yeah right...

The iMac is nothing at all like the Mac Pro acoustically. E.g.,
the front of a Mac Pro is covered in holes, hundreds of them.

My Mac Pro 2009 is very quiet under OSX. I also use it for gaming under Windows 7, however, and I've had to bump the fan on the 4870 GPU to a mildly annoying level to keep it in the 50-60 C range for that rather demanding application.

This is the video card, I replaced my 2600 with a GT 120 and that "WHIRRR!" at boot/wake is gone. :)

Only time I even know my machine is running (other than using it), is when the house is completely empty and silent. Then you can make out idle HDD noise and fans spinning at low rpm.

Keeping the computer clean is also a huge factor in how loud your fans will be. The more they collect dust, the louder the machine becomes. This is especially true for the gpu. Plus, keeping the dust out allows everything to flow quickly and unobstructed as it was designed. I know I have to blow dust out about once every couple months to keep it from building up.

As usual, with a small remark. ;-) No - no, you absolutely right, but:
i have macpro1,1 (same **** for all other with fb-dimm ddr2) memory same but chilling system differ. Even if you got 3rd party heat sink, not all memory suites. Not all cards flashable, card can have different board revisions and so on (yeah i got sapph4870 with qimonda memory and i have had a nice sex when i was making bios for this card). And remember not everyone lives in US. So fully charged mac pro for me coast like helicopter. ;-(

I think he meant the PSU's rated limit.

But most systems aren't drawing that much power, even with upgrades. Nor do we actually know if that value is nominal (continuous), or peak. Most units list their peak power output, not their nominal (sustainable values). But at 12a off the wall, I'm thinking it's nominal in this case (though they're not typically that efficient units anyway). Assuming 115V AC @ 12A (rather than 125 or 110V), then it can pull as much as 1380W running full power (71% effecient).

My Mac Pro 2009 is very quiet under OSX. I also use it for gaming under Windows 7, however, and I've had to bump the fan on the 4870 GPU to a mildly annoying level to keep it in the 50-60 C range for that rather demanding application.
Mine tends to idle at ~50C. :eek: :p

Apple needs to "get with the times". What's Al Gore doing on the board???

Dell advertises an optional "85PLUS" aka "85 Percent Efficient Power Supply" for their T3500 workstation. Yes it's an extra $50, but with the margins that Apple has on their Mac Pro, they can surely afford to do better than 71%.

Fortunately, as you point out, neither system is likely to be drawing anywhere near the max power, so while the percentage differences on efficiency appear quite large, the actual wasted energy will be much smaller. At idle the most recent quad-core Mac Pro (http://support.apple.com/kb/ht2836) is only drawing 115 W.

Absolutely. Doesn't make sense to buy a Mac Pro as a gaming only machine, Windows based computers can do much better for less money.


What am I missing? Is there a way to get 10 hard drives into a Mac Pro? How do you get to 20 TB?

10 drives is absolutely no problem, you can get even more in there.

4 x 3.5" drives in the sleds = 8TB
8 x 2.5" drives in the ODD bay = 8TB
4 x 2.5" drives vertically mounted in front of the PCIe cards = 4TB

________
makes a total of 20TB internal

You could expand this to 28TB if you use two PCIe to 2.5" adapter boards. There are boards that just use the space of the PCIe slots and allow the proper mounting of 4 2.5" drives.

The other two PCIe boards would have to be occupied by a graphics hard and a very decent RAID controller.

But I'm pretty sure that no one ever did this because most people prefer external RAID systems or a dedicated file server.

Lol, does it really matter? 8TB is the current "Apple official" maximum (using only the stock 4 bays with 2T drives), and as far as I know SATA has no restrictions on drive size. So the maximum will be determined by the max drive size offered. Of course there are those who fill their optical bays with additional HDD's. Heck, theoretically you could run it headless with a raid card and stack a few drives on the lower fan/cpu enclosure with the door off for ventilation. Not the prettiest solution though. lol
