Lot of Noise on my Mac Pro 3,1

Hello,
I've a big problem with my Mac Pro and I want to know if it's normal or...
It's doing lot of noise from de Fan even I restart the SMC.
When I'm starting it it's ok. But about 5 minutes the fan do lot of noise.
Here is the fans mesure :
Exhaust Fan : 1057rpm
HD/Expansion : 1900rpm
What can I do !
I've by this Mac Pro because it's the top of apple but this noise is not mormal for the price...
Please help me.
Thanks,
Benjamin

Resetting the SMC really requires leaving unplugged overnight.
What is important is the temps. And iStatPro tends to be off slightly, ballpark figure should be okay.
Keeping the internals cool is why the fans kick in unless a thermal sensor is not working or misreading/misreporting.
Keeping the fans running slightly elevated an extra 300 rpm can be enough to keep everything cool and from getting so warm that the system has to kick fans into highgear like 1900 rpm.
Also, what PCI cards do you have? RAID controllers etc. How many and what type of hard drives; are there any drives in the lower optical drive bay (which is normally fine, but to get a sense of what you are running).
Make sure the room is not overly warm, that there is good ventilation, and that the exhaust out the back has some place to go and circulate and not come back inside. The worst is when the Mac Pro is in a corner, or inside a "computer hutch" which doesn't allow it to breath adequately.
Finally, run Apple Hardware Test. That will kick the fans up to 2500 rpm for a couple minutes, totally normal and just testing everything briefly (but if you aren't prepared or had never heard fans run @ 2500-3000 it was scary for me the first time).
I would use Hardware Monitor, or Temperature Monitor. Watch FBDIMM temps as a good indicator.

  • Extremely Loud Fan Noise Brand new mac pro 12 core 2.93

    The fans of my brand new mac pro start making a sound like a wind tunnel several times a day, and won't stop till I shut off the mac.
    Fan stats are like this when it makes that sound:
    PCI  799rpm
    BOOSTA  5048rpm
    BOOSTB  5188rpm
    Exhaust  2709rpm
    Power sup.. 599rpm
    INTAKE 2697rpm
    Anybody any idea what could be wrong?

    Hi, I had the same problems. I had to have replaced the fan that was broken.

  • Mac Pro ATI5870--uneven fan sound when idling..any thoughts?

    I recently had a noise issue with my new Mac Pro with the ATI RAdeon 5870 card. There was a lot of noise when the fans cranked up. Apple techs here in Paris took the machine and said they put it under an Apple analysis and test over night and now the noise that they heard themselves is now gone. They replaced nothing. They repaired nothing. Though I can hear the fan on the graphic card increase in spin noise when it rises above idle, which I presume is normal, it is somewhat better than when they took in the machine for repair. However, when the computer is idling and the graphic card is idling under no load I can now hear more of an uneven fan noise, which is disturbing. It's as if you can hear the fan changing its tone or tonality, moving up and down in tone as it idles.
    It's not all of the time, but most of the time when there is no load on the card. Like an uneven humming under lowest fan speed.
    Doe anyone else hear this symptom? Is it normal as the fan or bearings are running at their slowest? Everything else so far works ok graphically with the card. (I had a MBP 17 that made noise when idling once and they replaced the two fans in the back and the noise was gone.) I realize this is a high performance graphic card and I do work in a quiet space, but if replacing the card would net me a more even sounding working environment I would risk it. If not, then c'est la vie.
    Thanks for any advice.

    Someone else suggested that they heard a similar noise on their Mac Pro but for them it was emanating from the Intake and/or Exhaust fans running on their idle speed of around 599rpm.

  • Stock Mac Pro 2.66 Quad Nehalem + new memory

    Hi,
    Probably this was covered but I can't find it. I'm waiting for my brand new Mac Pro 2.66 with the stock configuration of 3GB of memory. I know it's not enough because some of my projects use more (Logic Pro + Kontakt 3.5 and a Play library) and I know my current system has never went further than 3.7GB (according to iStat nano widget) though I have 8 gigs. So the first option is to buy just a 2GB module to have a total of 5GB in 4 slots (21+11). Or to buy the 2GB module and have 4GB (211) in 3 slots? I've read the DIMM replacement DIY pdf from apple and found that it's better to fill the first 3 slots and leave the 4th empty because it can decrise system speed. How much slower will the system be if filled 4 slots? Can I have one 2GB module and 2x1GB modules installed? Which way is best? Or perhaps I have to buy a 2x2GB pair and leave the 2 last slots empty?
    I have to add, my G5 quad speed is enough for me and I'm upgrading not because of speed issue but because more and more developers abandon the PPC world.
    So to cut a long story short: I need more RAM (total of 4GB or 5GB is enough). Can I mix different size modules (ie. 1GB and 2GB)? what system slowness can I expect when the 4th slot is filled?
    I hope my thoughs are clar Any comment appreciated.
    Best,
    Wojtek

    Thanks for your input! I've just bought 1GB for penny and will observe if it's ok for the moment with the total of 4GB. After installing all the apps and plugins (I guess it will take some days because I have some folders back from Logic 6 somewhere in the Library folder and from my experience I know they have to be in specific places because Logic or EXS will look for them) I will open my most demanding Logic sessions and see if the memory is enough. Unfortunately there is nothing like Apple Poland and I can't buy directly from Apple (even from their German or UK shop), this is ridiculous, but that's another story. I found a reliable supplier in German Ebay - PureMac and I most probably will buy from them if in the need.
    BTW This Mac Pro is soooo silent comparing to my G5 quad! I have one of those fan equipped UPSs and it generates more noise than the Mac Pro!

  • Windows – but Which? (What to install on Mac Pro Quad Core?)

    First, apologies in advance if this seems like repetition of a recent topic, but I read through the recent "Vista vs XP" thread and it didn't quite answer my questions.
    Basically, I'm planning on buying a Mac Pro "Quad Core" 2.8 and installing Boot Camp and a Windows OS startup. This puts me into the notoriously tricky area of picking the right version of Windows for my needs, something I haven't really had to deal with in regards to OS X.
    Basically, I'm not looking for something with too many bells and whistles or to much bloatware built into the OS. Also, I'll probably be using some older software/shareware, so backwards compatibility is an issue. On the other hand, I'd like something that works with the Quad Core architecture at its greatest efficiency.
    This means I'm wondering about a couple of features that I may or may not need, and it would be of great help if you folks could point me in the right direction regarding these:
    x64 – Since the Xeon processors in the Mac Pro are 64-bit processors, am I better off with "x64"-compatible versions of Windows (either Windows Vista or x64 versions of XP)? Will this cause problems starting up older programs that may not have been written for x64?
    *Dual Processor Support* – the Quad Core, of course, is a dual processor – will I get better performance from a version of Windows that list "Dual Processor Support" among its features (basically, the "pro", "business", or "ultimate" versions of XP and Vista)?
    If I need those features, I'm probably looking at getting either the x64 version of Windows XP Pro or the Business or Ultimate versions of Vista. However, I'm leaning against Vista based on backwards-compatibility and bloatware issues. That leaves XP Pro x64, but I might go for a more basic version of XP if I find out the x64 or DPS features aren't actually something I need. (The other "extras" in XP Pro don't sound like anything I need.)
    Also, I'm likely to install Parallel Desktop at some point and don't want a version of Windows that would have compatibility problems there, either.
    Anyway, any answers you folks can provide for me in this regard would be very helpful.
    Thanks in advance,
    Peter

    Truth is, I am disappointed in VMware Fusions slow walk toward full support for 64-bit and SP1 but 2.0 beta is getting there. Never used Parallels but best to check their own support forums. They also updated the 1.x version recently.

    You don't need anything first, except I would start with a new hard drive for Vista, don't even do anything with it and pull OS X drive, boot Vista DVD and go from there, just as you would normally. Much easier. After it is installed is when you need Apple BootCamp from your Leopard OEM DVD, install, and then Apple Software Update will take care of 2.1. And install your graphic drivers yourself.
    The problem(s) come with trying to use BootCamp Assist and setting up partitioning, and it only makes it harder - not easier - on Mac Pro (you aren't and don't want to use your OS X boot drive).

    And their Mac Pro area http://forums.macrumors.com which has a lot of Vista talk from Mac Pro owners.
    The only real issues are which graphics card to get today or in next weeks, what drives you are going with and other upgrades like memory (8 x 1GB is actually a good base ideal figure so all DIMM slots are taken up).

    - until the WD "Black" series (I guess Blackbird name or SR71 are already taken) along with 3rd generation of their RE series drives. WD has been popular, reliable, with Mac Pro for last two years. Can't say the same of every vendor. Samsung F1 is also a real winner.

  • Mac Pro: 2nd Display Problem

    Hello,
    I have been having a lot of trouble with a Mac Pro and separate displays. First, it took me quite a bit of playing around to get it to recognize the first display plugged directly into the DVI port. I then went to add a second monitor through a mini display port to DVI adapter, and I cannot get the Mac Pro to recognize the monitor. Nothing shows up in display to suggest that the other monitor is there. Clicking on Detect Displays does nothing. Thinking it could potentially be a bad video card. I am also sure that the adapter, cable, and monitor are not faulty.
    Thanks!

    The video card is an Nvidia GeForce GT 120 512MB RAM. It is a Mac Pro 4,1. I have double checked every connected and I know nothing is loose. Also, when changing out trying to change monitors in hopes that it would be detected, the Mac shut down because of a problem. All of this keeps leading me to a bad video card.

  • Mac Pro 12 core 5,1 GPU upgrade

    Hi,
    I do most of my work in AE CS6 and CC, video edit in PP and use C4D. I want to upgrade my GPU and cannot seem to find the right info. Should I use a GTX 680 or a AMD Sapphire HD 7950? I don't use Ray-Tracing in AE. I'm looking for fluid workflow with better preview and hoping for better rendering time. Would I benefit from the CUDA or invest in a AMD? So many info out there... Thanks a lot for your help.

    Head over to the MacRumors forum and look for a user called "MacVidCards".  Or hunt for some of this stuff on EBay.  The reason I say this is: Dave will flash just about any PC-based nVidia card so that it runs properly in a Mac Pro.  So you don't need to buy "old tech" such as the GTX680 (which is 2 generations old at this point).  As long as the GPU can be powered by the available plugs in the Mac Pro, Dave can make it work properly in the OS.
    If you're dead set on commercial cards that are supported on the Mac without going through a 3rd party, I'd recommend the GTX680.  OpenCL (which runs with the AMD cards) is still in "catch-up" phase with nVidia's CUDA.  Both from an Adobe perspective as well as generically.

  • Will a 2.66 mac pro accept SSD flash storage drive?

    I am trying to find out if Mac Pro 2.66 OS10.6.8 will run properly using the SSD Flash storage drives that are now available?

    I love just really get a lot more out of my Mac Pro now with Samsung $100 SSD than I ever did, and OWC or Amazon $15 adapters.
    One easy great way to breath new life into 7 yrs old hardware.
    $31 for 2x2GB FBDIMM to get more RAM is another easy and now cheap higher quality.
    I feel like I bought a year and can skip "1.0" of any new OS plus new hardware until it too has had 6 months at least to iron itself out.
    Don't be put off. That SSD III can and should work fine AND use it whenever you do get another Mac or decide to add a PCIe SATA SSD controller card ($150) to add SATA3 6G.

  • 1 week old Mac Pro & Seagate drive - on its way out already?

    Hi y'all,
    This post is just an observation..
    I just noticed tonight a constant whirring kinda noise from my Mac Pro. Thought it was the DVD drive/s but no different when ejected. Decided to unmount the drives one at a time and it turns out to be the Apple supplied 500GB Seagate making the noise. It sounds like a low toned whine with a change in note every revolution. Very annoying, but NOT as annoying as having to uninstall and back it up ready for a replacement!
    Thank goodness for Applecare, I'll update with the response I get tomorrow.
    Well I won't be buying another Seagate, think I'll buy another Maxtor Maxline II as it has been very reliable.... and quiet to boot!
    Ciao 4 now
    B

    AMUG will probably run some tests and do their normal thorough job reviewing the card.
    Someone found that the Intel SATA chipset used in the MacPro is capable of RAID5, but it isn't enabled, which would be interesting also.
    The drive trays are cable-less, no data or power, rather they plug into and make connection on a backplane, and no way or room for cables - you'd probably have trouble closing the case and/or need to put the drives in backwards.
    So running cables outside, out another PCI slot, kinda sloppy, and you'll need shielded cables.

  • HT1338 Problem: My Mac Pro is heating and the fan produce a lot of noise, what shall I do? I got the new Montain Lion

    Dear best Users,
    What shall I do? My Mac Pro 2.53 GHz Intel Core 2 Duo/OS X 10.8 13-inch 2009= Is heating and producing a lot of noise with the internal Fan.
    Best,
    Dario van der Lündin

    If you can, open Activity Monitor and see what's using up all the %CPU.
    If its kernel_task, shutdown immediately and do a PRAM reset, like this:
    1. Power down the machine.
    2. Locate the following keys on your keyboard in preparation for Step 4:
    ‘command’ – ‘option’ – ‘P’ – ‘R’
    3. Press the ‘power on’ button.
    4. Immediately – and before the grey screen appears – hold down ‘command-option-P-R’ all together.
    5. Keep them held down until you’ve heard the start-up chime twice. After you release them you should hear it again, and hopefully your Mac will boot up as it should and with the kernel_task process back to normal.
    If that's not it, try quitting whatever the process is by selecting it in the Activity monitor window, then 'Quit' in the task bar. If the process refuses to quit, post back with the name of the process.

  • New mac pro making a lot of noise

    my mac pro is not even a month old... but after about 15 mins of use it makes a lot of noise.. i think it's the cooling fan. it is noticeably much noisier than my 3 yr old macbook. and it seems to get pretty hot as well (hotter than my old macbook)...
    has anyone got the same issues?

    During the time it's getting really hot and you're not doing any heavy-load work, check Activity Monitor and check your CPU usage. Do you have any apps that are hogging the CPU at that moment? Carbonite is a big problem with CPU usage, if you have that installed, I'd watch that. Also, you could try downloading some utilities that check fan speed/temperature. If the fans are revving for no real reason, could be an issue.
    It wouldn't hurt to reset the PRAM and SMC, as this can have an affect on the fans.

    My Mac Pro makes a lot of loud clicking processing noise for simple procedures like surfing or using finder. Bought in 2006, the problems I think started after an upgrade to Snow leopard this year. Any help???

    Although it is often refered to as "Number Crunching" computation does not actaully make any loud noises.
    A failing Hard Drive does. Are your backups up-to-date?

  • Mac Pro 8-core Power Supply Making Humming Noise That Comes And Goes

    This is in reference to a Mac Pro 3,1 8-core purchased around Feb 2008.
    Lately, I've noticed a strange noise coming from my power supply that sounds like the noise a refrigerator radiator makes. It's a humming noise that rapidly comes and goes, constantly.
    The power supply fan speed is running at 599rpm
    I'm not sure if the problem could've been caused by adding additional ram (12GB, OWC) or an additional HDD (3rd HDD, WD), but I didn't really notice the noise until after adding these components.
    What could be the cause of this problem? What are my repair options if necessary (without Apple Care)?
    Thanks in advance.

    I know for a fact it is not any of my hard drives because the noise is becoming more frequent no matter what hard drive I use, I actually have a 1.5tb, a 1tb, two 500gb and two 320gb drives, I have set an appointment to take my system in and have it tested, it is starting to crash 5-6 times a day. I can not get a lot of work done with this annoying spinning noise and the shutting down. Thank god for my Apple care, and I have visited various forums that lead me to believe its the power supply going out, with the symptoms it is having. This article and others like it explain what to look for when a power supply is going bad.

  • My Mac Pro Early 2008 is making a cricket noise

    Hi all,
    My computer started making an annoying noise. It's exactly the same like a cricket. I removed hard drives, SSD, CD-ROMs and turned on the computer again but the noise is always present. If you scroll down with your mouse, it increases the noise, if you stop doing things it kinda goes down in intensity but it's still present. Does anybody know what is the reason? I am going to replace the PRAM battery, maybe it's the reason. I also reseted the PRAM but it didn't work.
    I would appreciate your feedback. Thanks in advance.
    David

    Honestly, I would first try to just clean off the fans of any dust (a slighlty damp paper towel will work fine).  If they have much dust or dirt on the blades, that can throw off the balance enough a fan starts to chirp.  But the fan itself is still fine.
    If you do need a replacement fan, there are lots of places online to get them - amazon, ebay, http://www.macpartsonline.com, http://www.powerbookmedic.com (despite the name of that last one, they do sell Mac Pro parts too).
