Fans running fast on mac pro

This quesiton has been brought up many times before, and I've tried the suggestions everyone has offered in resloving the problem of fans running fast on a Mac Pro. In my case they started running fast after Sleep, Restart or after Startup. I have a 2007 Mac Pro and have reset the PRAM and SMC in the past and these, along with updates from Apple, seem to have resovled the problem. Recently, however, I began to have this trouble again and went throught the motions of resetting PRAM and SMC. I even reinstalled my OS Lion to see if that would resolve the issue, but to no avail. So this is why I am writing. In an effort to give someone else a heads up to a new problem I incurred that hasn't been brought up in any discussions on the subject to this point; that I can find, anyway.
About 8 months ago I had one stick of Ram blow on me. I sent it back to OWC and it was replaced no problem. Then I noticed a month ago that all the RAM on my lower riser, except the replacement stick, had blown. Again, all were replaced and this is when the fan issue arose. I tested the RAM on the Upper Riser in the lower slot and they worked. I put the Ram from the Upper Riser on the Lower Riser Board to make sure it worked, and they did. I did this, however, after thinking I had blown the Lower Riser Board and ordered a replacement...glad I did. I now had 8 sticks of Ram in the Upper and Lower Riser all working well, but had a computer that sounded like a 744 just before take off. After numerous attemptst to fix the problem and searching long on the internet I decided to try the New Riser Board I had bought. It workded. That Lower Riser Board, for what ever reason, must be foul somewhere/somehow. I now longer have the problem.
So, I suggest you follow all the advice of those who have written before me because their suggestions worked initially. However, if you've had blown RAM recently, or maybe are about to and this is an indicator you have a Riser Board problem, you just may want to check your Riser's one at a time in both slots to see if the fans run fast while Board is in and the other is not.

  • Geforce 9800 GT Running On Early Mac Pro (EFI32)

    I arrived at this point from another thread, which is here:
    http://discussions.apple.com/message.jspa?messageID=8988306#8988306
    To make a long story short, I now have a 9800 GT running safely on my early Mac Pro.
    It is a single GPU solution and it works reliably under both Mac OS X and Boot Camp Vista Ultimate 32 and is the fastest GPU (according to the Open GL benchmarks) I've ever seen on any Mac Pro. Absolutely no artifacts under either environment and the Crysis series is easily handled in Boot Camp. Still testing though...
    Here is the specific GPU that's now installed:
    http://www.newegg.com/Product/Product.aspx?Item=N82E16814187026
    The dual fans make it insanely cool. It's also quiet and while perhaps a useless observation, its setup of copper heat sinks and connectors, etc., appears very practically done while also being a kind of attractive arrangement as well.
    My 9800 GT is a reflashed PC board by bruinmacs:
    http://shop.ebay.com/merchant/bruinmacsW0QQ_nkwZQQ_armrsZ1QQ_fromZQQmdoZ
    As for installation to replace my also very fast 8800 GTS, I had to remove the side rail (two screws) and the daughter board (small lcd display) from the standard 9800 GT so it could fit in the lowest slot. The small lcd is not helpful for us Mac Pro owners.
    I don't know for sure, but I believe this board by bruinmacs will run in any Mac Pro (it is PCIE 2).
    FYI...
    Cheers,
    tyvol

    Thanks for the reminder hatter...
    I think that you are correct that the ROM's on these reflashed PC GPU's should be targeted to either the EFI32 or EFI64 Mac Pro version.
    I forgot to mention that in addition to reflashing the 9800 GT with their ROM update for my EFI32 Mac Pro, bruinmacs also first increased the ROM to 128k.
    Don't know for sure (bruinmacs would, though) but it seems to me that with the proper EFI32 or EFI64 ROM reflash, this 9800 GT could work in any current Mac Pro.

  • Power Supply Temperatures Running Hot! Mac Pro shuts down.

    Hello,
    First I will give machine/hardware specs of interest:
    2 x 3 GHz Quad-Core Intel Xeon (pre 2009)
    8 GB 800 MHz DDR2 FB-DIMM
    NVIDIA Quadro FX 5600 (running 2 displays)
    Apple RAID Card/Controller
    SMC Version: 1.25f4
    *venting dimensions around computer: top=18", left side=3", right side=3" and back=18".
    Software of interest currently running:
    OS X 10.5.8
    iStat Menu
    SMC Fan Control
    My machine has been shutting down spontaneously and I suspect either CPU or power supply overheating. In the 5 instances this has occurred, the room was very warm (AC was not on) and I was running HandBrake with CPU at full and an iStat reading of 145 F. Ambient was 77 F and I was not reading power supply temps at the time. I figured for sure this must be a CPU overheating issue. However, just a few hours ago I had another shutdown. The room was warm again but I was not running Handbrake, but StarCraft II. I have played a lot of Starcraft II with no problems until tonight.
    I decided, this time, to check the temps on my power supplies. Power supply 1 = 147 F, and #2 is at 178 F. After many hours of searching forums I have concluded that these are crazy hot temps! I immediately installed SMC Fan Control to attempt to increase the fan speeds. I was successful in increasing all fans except the power supply (stuck at 599rpm). I have now turned the AC on in the house and the Ambient is down to 70, PS #1 145 and PS #2 169. All of these temps are a result of and idle machine running a browser.
    The following may or may not be an issue, however, leave no stone unturned. I currently have 12 external devices running on USB. 4 WD passport drives, 1 DVD writer, 5 WD powered drives plus the keyboard and mouse. Also, the Mac Pro is plugged into a small UPS.
    In all my forum searches, I just can't seem to answer some basic questions:
    1. Can an overheated power supply shut the system down?
    2. What are optimal (normal) running temps for Mac Pro's? (everyone seems to have opinions, but there doesn't appear to be a technical specification anywhere).
    3. I thought the fans, especially CPU fans, were supposed to kick in when the heat rises. Why are mine staying at minimal rpm's?
    Finally, does it look like I need new power supplies? Fans?
    This machine was put into service in March of 2008 and has done very intensive rendering for the film industry...long nights...rendering for days sometimes. It has been retired for over a year now and is used at a lesser degree.
    Thanks for reading this long post! I appreciate any input you can provide!
    Other iStat reading of interest:
    Power Supply 1 voltage = 12.28 V
    Power Supply 1 current = 26.44 A
    Power Supply 1 power = 316.75 W

    Also, the Mac Pro is plugged into a small UPS.
    Put your peripherals on that.
    Don't share the same circuit for A/C as the Mac Pro, and put the Mac on 1300VA UPS at least.
    As for all those external drives.... I'd consolidate into a good SATA case or two.
    And yes in summer run with 3 of the fans up around 900 rpm.

  • Fan Running Continuously Power MAC

    Mac PRO  Dual Core Intel Xeon Processor   OS X 10.6.8
    Front and rear fans run constantly.
    I have shut down, unplugged, waited and restarted.
    Tried only using a single application at one time.
    In an air conditioned officce.  It is very cool.
    Unplugged computer.   Opened case.  Carefully cleaned out dust as best possible with mini vac and soft brush.
    Offered relief for about 45 minutes then fans come back on.
    Hmmm!
    Any ideas.
    Thank-you,
    John L.

    UPS? something else on the same circuit your Mac runs off?
    (Mac Pro are not Power, Power = PowerPC, not "Intel Inside" Xeons.)
    The way to reset SMC keeps being rewritten. I don't put much into unplug and wait. Mine would be reset every night when they go with no AC current (I turn off UPS as I hate to see light it has)

  • G4 Wont Start Up No chime and fan runs fast.

    Hi Mac Users,
    I am at my wits end! My Mac won't start up.When I switch it on there is no chime and the fan runs fast.
    I have checked the battery and it is OK.
    Tried the reset button and no joy.
    I have reseated the ram memory still no improvement.
    I am completely lost without my computer would some kind soul point me in the right direection?
    It is the hub of my recording studio and my life cos I'm disabled.
    I have read a lots of posts on here and I feel I am getting confused with too much information.

    The red LED indicates power to the logic board, which is good.
    Try Resetting the Logic Board
    Resetting the logic board can resolve many system problems. Whenever you have a
    unit that fails to power up, you should follow this procedure
    before replacing any modules.
    1 Unplug the computer.
    2 Press the Power On button on the front of the unit.
    3 Open the side access panel.
    4 Remove the battery from the logic board.
    5 Wait at least 10 minutes before replacing the battery.
    6 Make sure the battery is installed in the correct +/-
    direction.
    7 Reassemble the computer and test the unit.
    Note:
    This procedure resets the computer’s PRAM. Be sure to
    check the computer’s time/date and other system parameter settings

  • Fans running fast

    OK. When I install the 10.5.8 combo updater and restart the Mac it closes down as far as the screen goes blank, but then the fans start running slow at first but after about 2 minuets they are running as fast as possible, should I leave them running? I have left them in the past for up to 2 hours but then I decided to push the button to force quit, just how long should I leave them running? And is this normal?
    Thanks

    That is a retail upgrade to a new system; not a gratis update within one.
    The ownership & use of a retail 10.5 Leopard DVD installer disc set is required.
    A disc from another computer won't work in a different one, so that's out, too.
    +In your post's signature line, you say the G5 shown is running 10.5.8; if so+
    +do you have another computer now, with 10.4.11 installed? Or was the issue+
    +you had mentioned, due to attempting to run the Leopard 10.5.8 update step+
    +in a Tiger 10.4.11 system? Usually, those kinds of things never get very far.+
    (If you know someone who has upgraded to Snow Leopard 10.6, & has
    no further need for their old 10.5 installer disc set, they may make a deal.)
    Sadly, the normal retail sources for buying a new/unused Leopard 10.5 disc
    set won't have them; so other options and sources have to be examined or
    researched. One possible source may be to call the main Apple phone number
    for the sales support (see web page) at 1-800-MY-APPLE and ask for a Mac
    OS X 10.5 specialist; and inquire about the purchase of the Leopard 10.5 full
    install disc set, which is essentially the retail disc for a complete installation.
    +In regions outside of North America, you may have to contact your nearest+
    +Apple main sale support & inquire about getting the Leopard OS X 10.5 discs.+
    The best way to upgrade to Leopard 10.5.8 is to have a separate hard disk drive
    (if you have a tower computer) for it, all alone; no old Tiger or other OS X parts.
    And if you use iLife, get a later version of that suitable for the hardware in your
    computer; as not all older Macs can support the latest iLife. Some may prefer to
    be using iLife 06 or 08, if they don't have all the newer stuff. Older ones may be
    better with an even older version. Since iTunes is a separate download item, that
    may also be too much for some ancient computers. Of course, newer iPads and
    other items probably need to get into the iTunes store and interface with the Mac.
    Those would require the minimums as indicated by their system requirements list.
    If you are on the lookout ahead of time, getting a clean no longer in use Leopard
    DVD retail installer disc may be a matter of timing and luck, in your vicinity. A few
    weeks ago, a craigslist ad had some Apple OS X software including the 10.5 DVD,
    in the box with book; an iLife 08 in box with instructions, Garageband jam-pack, a
    white Apple usb keyboard, and iWorks 05 in the box with paperwork; all for $50.
    And someone else, a few years ago, gave me an early retail Leopard 10.5 DVD.
    So, I could easily upgrade one of my Macs (again) to Leopard 10.5.8 and have no
    old Tiger system parts inside the computer at all. - A clean break, as I'd done before.
    Be sure your computer has better than minimum hardware requirements to run
    Leopard 10.5.8, including more than enough RAM, large capacity hard disk drive
    with large cache and good read/write speed; and a good Superdrive optical drive.
    If the issue with the 'fans running fast' has been resolved, or is conditional, you
    could add whatever new info you have in this thread. And if you are considering
    an upgrade to Leopard 10.5.8, issues outside of the actual computer hardware
    seem to appear in the Leopard discussion page, if you needed to start a thread.
    Sometimes, getting the dust and other debris out of a computer so it can breathe
    and get adequate air-flow, can help it run cooler. But sometimes, there are other
    possible reasons why, if it is running too warm, for it to be doing that. Do you have
    and use a Temperature Monitor software that an be read in the main menu bar?
    A temp widget is mostly pointless, since in order for that to work, you have to stop
    most everything else & run DashBoard. That can further load the system, to make
    it run warmer; if the issue of heat and fans remains an issue to be watchful over.
    Hopefully a few of your questions or curiosities are finding answers; at times, a
    fair gamble on information can be a google search. If worded adequately.
    Good luck & happy computing!

  • XServe fans running fast and loud

    Good morning
    I have searched the information base and tried a few suggestions without success.  Hoping for another solution here.
    I have an Intel based XServe (2008) (OS 10.6.8) whose fans are running faster (and therefore louder) than they have previously.  This follows on the heels of a power outage (two of them actually) here at school, though the server is behind a UPS.  The system identifier light is also blinking in a particular pattern - 4 flashes and a pause repeating.
    The server is up and running, teachers are connecting to it just fine, the RAID is intact and online, the drives all look good according to Disk Utility.  So, functionally, everything looks OK - the fans are just running faster and louder than before - noticibly louder than the other Intel XServe in the rack.  The server is at the top of the enclosed rack with a space below it as it has been for the last 4 years.
    This summer I took all the XServes out of the rack, opened them up, and blew the dust out of them (including a moth - truly a bug in the system), so the all the airways are clean and clear.
    I have tried the suggestions I could find on this forum:
         restarted a bunch of times
         shut down and disconnect everything (including power) for a period of time
         reset the PMU/SMC or whatever it is called doing the front panel buttons with the blue lights on the lower row
         reset the PMU/SMC or whatever it is called by holding down the power button while disconnected from power
    I have installed iStat Pro and the temperatures are averaging around mid- to upper- 30°C and the fans are running around 3000 RPM .  The temperatures aren't signifcantly different that the other XServe, but the fans are running about twice the speed.
    I had to reformat the RAID earlier this weekend and copy over the data files from backup and reassign permissions, but the server was running quietly after that was all finished.  It seems to be post-powerbump that the fans became noisy.
    Sorry for the long post, but I tried to include all the pertinent information.  I would have tossed in photos and videos if I could have!
    Any suggestions would be appreciated.
    TIA
    Greg

    Did a little more searching about setting up LOM on the XServe and I think I have it figured out now.
    I assigned a unique (different) IP address to Network 1 in the LOM dialogue box in Configure Server menu of Server Monitor since I only have Ethernet 1 enabled and linked to a switch using a unique (different) IP address for network traffic between the XServe and my clients.
    I can now see (via Server Monitor remotely) that I have a dead blower in my fan array which, upon closer inspection, is also evident in the iStatPro display (one fan running at 18 RPM).  Hence the blinking system identifier light and the other fans running faster and harder (and noisier).
    Oddly enough, I have a replacement fan array in a box of XServe spare parts.  I now have a weekend task.
    Thanks for all the information to be found and the people participating in this forum.  Love it.
    Greg

  • Satellite C55-A - after BIOS update cooling fan runs faster

    Hello,
    I was informed by Toshiba application that new BIOS version is available I confirmed it and BIOS was updated. Now I have problem. Cooling fan runs faster than before and it is very annoying.
    Can I find older BIOS version somewhere and roll it back? I don't need it if it doesn't work properly.
    Now I have version 1.40. Is there some solution for this new version?
    Message was edited: posting has been translated

    Toshiba EU driver page provides only the latest BIOS version.
    Furthermore the BIOS downgrade isnt possible using the win-bases BIOS update.
    In order to downgrade the BIOS on Toshiba unit, you will need to use the traditional BIOS update method which requires special BIOS version. This is available only for authorized service provider.
    At the other hand there must be an serious reason why the cooling module run faster.
    Maybe the cooling method has been improved in new BIOS just to ensure that internal parts would be cooled down properly.
    Its just an assumption but I think it makes sense
    By the way: after each BIOS update, you should load the BIOS default settings and should save the changes. If you havent done this in the past, do it

  • Will firefox 5 run on a mac pro running snow leopard

    I like FF but am concerned whether it will run on my mac pro running snow leopard, since the download information says it is a windows program.

    Snow Leopard being Mac OSX 10.6
    You need to download the version for Mac, not the .exe which is for Windows.
    www.mozilla.com or if you prefer a certain language no given then look at http://www.mozilla.org/en-US/firefox/all.html and look down the middle which is Mac OSX.

  • Iavd is 98%, computer gets real hot, fans running fast

    Hello,
    I see from some posts of last year, unresolved, I guess, that iavd (anti-virus?) is
    very high for no good reason, meaning it's taking lots of processor (space? function?) and the computer gets hot and the fans run fast.
    Mine has been doing that for a long time.
    Does Apple know what causes this?
    A fix might help lower my electric bill.
    Thank you.

    Not to mention computer wear and tear. I think it is the nature of the beast though, as all antivirus programs can have a tendency to cause a shorter life expectancy on a hard drive and other parts of the system. I skip the AV altogether on mine, and simply choose to browse carefully and stay away from filesharing apps and the like.

  • 2008 Mac Pro Monitor loses picture, computer becomes unresponsive and the fans run fast.

    My early 2008 Mac Pro is dropping the signal to the monitor and the fan on the back begins to run at max speed. I have to do a force shut down and start again. It will then run ok for several hours. This typically happens when it wakes up, I log in and begin doing a task. However, it has been known to do this at a random time. This has progressed to a once a day event mostly in the morning after it has been sleeping for several hours.
    I pulled the cover when it did it last and pressed the diagnostic button. LED's for the GPU and PWRG did not light.
    I am wondering if it is the power supply beginning to fail or if it is the logic board or, is it something else.
    Can anyone help with this?
    Thank you

    When using the Hardware Monitor software (from http://www.bresink.com/osx/216202/Docs-en/faq.html ) -- i emphasized the stuff in red
    The sensor X shows the reading Y. Is this normal?
    If you want to find out whether a sensor value is within normal limits, please select the menu item Window > Show Overview (or press ⌘+1) and look for the limits in the third and fourth columns of the sensor table. They contain the known official limits Apple has specified for readings acquired at the given sensor locations. If no limit is given in the table, this either means that it does not make sense to specify a limit for this particular sensor (e.g. the battery capacity should not have limits), or Apple hasn't published any specifications for this sensor.
    Note that all up-to-date Macintosh models automatically shut down or enter sleep mode if one of the readings exceeds a critical limit. For this reason it is impossible that your computer can be damaged in an overtemperature condition.
    For old computers without temperature managment, no limits have been specified by Apple. In this case use the following limits as orientation:
    Most older G3 or G4 processors are designed for a maximum operating temperature of 105 degrees Celsius (221 degrees Fahrenheit), measured at the chip die of the CPU.
    G4 processors of type 7455 or later (typically used in Macintosh systems with 867 MHz and above) are designed for a maximum operating temperature of 65 degrees Celsius (149 degrees Fahrenheit), also measured at the chip die of the CPU.
    Most desktop hard drives are specified for a maximum operating temperature of 55 degrees Celsius (131 degrees Fahrenheit). For exact information, use the Drive Overview window (⌘+8) to get the manufacturer and model code of your hard drive, and then direct your web browser to the manufacturer's web site to download the official data sheet for this drive. The temperature limits are always specified.
    ==================================
    And don't forget you can look at the fan speeds (there are several in the Mac Pro) - that sometimes will give you a hint something abnormal is going on if the fans start running a lot.

  • MacBook Pro Fan running fast after Mavericks update

    Hello All! I have a 2009 MacBook Pro 13 inch and I have noticed that after I updated to Mavericks my fan has been running really fast and my computer getting warmer than normal. It's always on a table so there is nothing blocking the port in the rear. Any ideas on how to fix this?

    Hey emilyiow,
    Thanks for the question. I understand that you are experiencing issues with your MacBook Pro in relation to the fans. Sometimes, this symptom can indicate that the SMC needs to be reset. For more information and instructions on how to do so, check out this resource:
    Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
    http://support.apple.com/en-us/ht3964
    After performing normal troubleshooting, these symptoms may indicate that an SMC reset could be necessary.
    Fans
    - The computer's fans run at high speed although the computer is not experiencing heavy usage and is properly ventilated.
    Additional information:
    Using Apple Hardware Test - Apple Support
    http://support.apple.com/en-us/HT201257
    What to do if you get an error in AHT
    Confirm that the power adapter is connected if you're using a Mac notebook.
    Confirm that all external devices are disconnected from your computer.
    Record any error code given so that you can give the information to a Mac Genius, Apple Authorized Service Provider, or Apple Technical Support Specialist.

  • Macbook pro 10.7.5 fan running fast and hot

    Recently (past 2 weeks) my macbook pro (just over 1 yr old) 10.7.5 fan has been running fast and hot. It begins after uploading photo's into iPhoto '11. Sometimes it takes 30 minutes for it to cool down and run at normal speed. Uploads are usually 50 to 200 images. I verified the Activity Monitor CPU % and nothing exceeds 12%.
    I did a restart twice this week which seems to be a temporary solution. Any tips to resolve this is appreciated.
    Happens when running iPhoto is only app open.

    When you were checking Activity Monitor, did you select "All Processes" from the drop down list at the top
