Can hear the fans blowing on Imac G5!?

I have had my imac G5 for a few months now. I have been noticing sounds. It sounds like fans or something blowing after the computer has been on for awhile. Is this normal??
*I know some other users may have noticed these sounds too*
Thanks in Advance!!

Well, this is the Intel iMac forum...but, I just got an Intel iMac, and I often do hear internal sounds...but nothing that sounds like a fan, so far anyway.

  • TS1587 I tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on you can hear the fan run, but the display stays dark. Any ideas what to do? Thanks Maja

    My iMac won't start up, or wake from sleep.  I've tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up.  Turning it on, you can hear the fan run, but the display stays dark.  Any ideas what to do?  Thanks!

    Mac doesn't boot
    Can you hear the fans and hard drive and see the white boot screen? Flashing question mark? The circle just runs and nothing happens? Only black screen and nothing else? These can be very helpful to diagnose the source of the problem. [1]
    Flashing question mark [2]: This is usually a sign of a failed hard drive. This indicates that boot up volume can not be found.
    Black screen: This is usually a sign of a failed logic board. There is no single reason for this and this may be caused by failed GPU, screen, CPU or RAM.
    Circle of death/no circle/blue screen: This is usually a sign of a hard drive failure. This may NOT be a dead hard drive, just broken permissions or something
    Gray screen/Apple logo/spinning gear or globe/prohibitory sign/folder with flashing question mark [3]: This could be a sign of faulty hardware but more likely a software issue, i.e. broken permissions, failed software update, etc.
    [edit]
    What to do
    First, hold down the option key (also known as the alt key) just after you've pressed the power button. This should show all the available options to boot from, so if you have Windows installed through Bootcamp or a disk in your SuperDrive, you should be able to see them along with your OS X drive/partition. Select the OS X partition with arrow keys and press enter. Startup key combinations
    If that doesn't help continue doing the steps from below:
    1. SMC reset [4]. Shut down and unplug all cables including power cord for at least 30 seconds and then plug in power cord and keyboard/mouse.
    2. PRAM reset [5]. Hold down option, command, P and R while booting. Start it when you hear the sound and don't let go before it reboots.
    3. Safe boot [6]. Hold down shift while booting to boot into safe mode. If this works, open Disk Utility from Utilities and repair your permissions and verify the disk
    4. Hardware test [7]. Insert the install disk (disk 1 in Mac which shipped with OS X 10.5.4 or earlier, disk 2 if shipped with OS X 10.5.5 or newer) and hold down "D" before the grey boot screen opens. Follow on screen instructions
    5. Boot from install disk. Boot from the disk that came with your Mac. Hold C while booting. Select Disk Utility from top bar and repair permissions and verify the disk. Reboot normally and see if it works now.
    6. Boot from another Mac (Firewire target disk mode). Connect the machines with a Firewire cable. Power on your Mac and press T. Select the other Mac's hard drive. Download the current OS X combo update. Run the combo update installer and select the drive that won't boot as the destination.
    7. "Repair" OS X. Boot from the install disk as in point 5. and reinstall OS X. This should NOT erase any data, just replaces the system files which may have caused your booting problem. Now install the latest combo update for OS X and repair permissions on your drive with Disk Utility.
    7.1. Install OS X into an external hard drive and then boot from it [8] and try to copy your data from the hard drive before proceeding. If you have done a backup recently, you don't have to do this.
    8. Restore OS X from Time Machine backup. Boot from the disk that came with your Mac and choose the Time Machine restore option. This step will lose any changes made since your last backup but the system and your data will be put back to exactly as it was on that date.
    8.1 Reinstall OS X. Boot from the install disk as in point 5. and select Disk Utility again. Now erase the whole hard drive and install OS X again. If you had a Time Machine backup and step 7 worked you don't have to do this.

  • My Powerbook will not power up, but I can hear the fan running...

    Please help!! My Powerbook will not power up, but I can hear the fan running when I press the power button to attempt to power it up. I just received a new power adapter because it wasn't working properly and it was doing this before and then it worked for a week and now it will not power up at all. It just starts the fan but nothing else turns on. When I plug the adapter, with the battery still connected, it will look as if it is charging but then the light on the plug turns from green to orange then off and doesn't power up at all. If I take the battery out and plug in the adapter, the light stays on but it does not power up except for the fan noise. Does anyone have any suggestions? I also followed the two articles listed online in regards to resetting the power setting and the command + alt + P + R as well. Nothing works. Thanks in advance.....

    Same here. If I start up with the power adapter attached, it starts up fine. If I try to start up from battery only, the fan comes on, the sleep light comes on but nothing else happens. I tried letting it sit that way for about 15 minutes and nothing changed. I tried attaching the power cord while in this mode and nothing changed. I tried the PMU reset a couple of times but nothing helps.
    This computer is just over 1 year old and I have not had any problems with the power cord (3rd party), the battery, or any problem like this before. It started after a proper shutdown last night and attempt to start without the power cord this afternoon.
    Any answers to this yet? I think I'll call on this and report any success to this discussion.

  • My MacBook pro wont wake up from sleep. The screen is blank at all times, but I can hear the fan for 5 sec then everything stops. Please help! I don't kno what to do.

    My MacBook pro is about 3 yrs old. It is a 2008 model right before the new design came out. Recently I closed it up which puts it to sleep and a couple minutes later when I opened it up the screen stayed blank but could hear the fan running but then the power clicked like it was shutting down and I could hear nothing more. My power supply is working and I have already tried resetting it. Can anyone help me? I don't live exactly near a Mac store to get help.

    Before resorting to an LB change-out, try this, as it has fixed many of the "silver-key" Macbook Pros with wake-from-sleep issues:
    1) To get the computer running, do an SMC reset. Instructions here:
    http://support.apple.com/kb/HT3964
    Your MBP model uses the first option under the subhead, "Resetting the System Management Controller (SMC)"
    2) If you get it running, go to System Preferences > Network and select your Airport connection
    3) In the result main pane, click the "Advanced..." button.
    4) You should be looking at a window with multiple tabs at the top; the "Airport" tab (far left) should be active---if not, make it so.
    5) There is a panel showing "Prefered Networks." Use the "minus" button below that window to eliminate any networks that you don't need to access on more than a weekly basis. I'm down to two: the home Airport Extreme Base Station and the network for a museum at which I volunteer once a week.
    5) Click "OK" and close System Preferences.
    Now try letting it sleep and see it if wakes up.
    When this happened to my Late 2007 MBP, I used Console to read system.log and found that, on waking, the compuer was looking for the wireless network at a lodge where I'd stayed weeks earlier and miles away. Clear the morass of old networks and keeping the list short has completely cured my wake-from-sleep issues.
    The steps I listed take less time to do than to read, and are within the ability even of novice Mac users.
    If that doesn't work, you may need to seek professional help. If you take it to an Apple Store and they recommend a logic board replacement, ask about a "Depot Repair." Instead of replacing the logic board on-site (which will whack you to the tune of US$700-1100), they send the computer to a central Apple refurb facility that fixes whatever they find wrong for a flat fee of about US$315 (last time someone reported using the service here). Turnaround is about one working week, and people who have taken of this service have reported being very pleased with the outcome.

  • I can hear the fan making a weird noise. What can i do?

    My brand new macbook pro is making weird fan noises, like something stuck or loose. I had the same problem with my windows computer. I got my mac two weeks ago. I did not pay $1300 to have the same problems.

    You make an appointment in advance. They look at it and tell you what's up. If they have the parts, they can fix it on the spot. (but they will take it in the back where they have a static-free workstation). Fan replacements (if that is indeed the problem) are straightforward, but the parts are special Apple parts.
    There is no need to touch any data, but service always begs the question, "Do you have backups?" If not, what if your drive died tomorrow?
    If you have an external drive, Time Machine is good because it does the backup (when the drive is available) automatically at low priority in the background. It does not interfere with your work.

  • Can you hear the fans on iMac? (my new 2011 27'' i5 fans are constantly audible even from a distance)

    I have the 2011 27'' Imac i5 and I can hear the fans all the time as of start. It's not super strong but clearly audible even from distance. istat shows normal fan speeds (1100/1300/1000 respectively) . The noise bothers me a lot especially in a silent room. The fans start to be audible immediately after switching on and get higher (+temperature rises significantly) under any easy activity .. like streaming a video from net.
    Can you hear the fans on yours at all?

    Do a SMC reset (maybe do it 2-3x) and if the problem persists as you have been advised call AppleCare.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • Major heat problem. should i be able to hear the fans?

    my black macbook with 1gb ram is getting very hot when i use front row to play videos at full screen. after about 30-40 mins the left corner of the macbook is so hot i can only touch it for a second or so. then without warning the video just freezes. the picture remains on the screen but looks like it's paused. i then get the spinning colour wheel. the only way to rectify is to force a power off (force quit has no effect). i have to let it cool down for a while and try again. it works fine after that until it gets hot again.
    when it locks up, it is completely silent. should i be able to hear the fans working? there is no warm air being expelled from any part of the unit as far as i can tell. the case is just really hot.
    i ran a little experiment by pointing a desk fan at the notebook and it played fine for five hours without problems!!! the corner of the macbook was cool to the touch.
    this happens in lid closed or open modes.
    anyone else have this or is it time to call applecare?

    UPDATE
    ok, so we have had the firmware update and guess what?
    all seems ok now!!!!
    coreduotemp now reports 65 degrees after playing video at full screen. much better than the 85 degrees it was hitting. now when it gets hot i can hear the fans going. i ran a terminal window and did yes > /dev/null and after only a few seconds the temp was rising to 85-87 and the fans came on really hard and brought it to 68-70. no system stall yet.
    normal idle while using only safari over airport is between 41-45 degrees!!!!
    i am very happy so far. lets just hope it is the cure.
    many thanks for reading and replying.

  • We have an iMac OSX Lion.I received a CD with photos on it by a friend of mine. She scanned the photos to her computer and gave the disk to me . I installed it yesterday. I can hear the disk spinning but no pictures come up. What would be the problem?

    We have an iMac OSX Lion.  I received a CD with photos on it from a friend of mine. My friend scanned the photos to her computer and gave the disc to me. I can hear the disc spinning but the pictures aren't coming up to view. Before having the iMac I had a Dell computer.  I was able to view the photos at that time. Is there something I can do so I can view them on my iMac? Thank you.

    The information I see in disk utility is the following: MacIntosh HD superdrive. 1TBST31000528A S Media

    Hello Bluebird,
    See if it's related to this...
    It also seems to be related to later OSX versions, like 10.8.x & 10.9.x
    The 2012 macs (and later apparently) (also later OSX versions on earlier Macs can do it also), not waking normally from sleep after hours being in sleep. (noted here ...

    "Why 2012 iMac/2012 Mac Mini won't Wake After Hours of Sleep (Hibernates/Powers Off)")
    The sleepimage file still reappears even if never slept. Delete it (hibernate off, etc) - within minutes its back.

  • TS1367 What to do when I do not hear the fan in my Powerbook G4 and it overheats and shuts down?

    My Powerbook G4 shut down in the middle of a power point creation. After a couple of days it booted up again. However, I do not hear the fan running the way it used to. I believe that the fan stopped working. I can use it but if kept on for more than 1/2 hour, it overheats and locks up. How do I get this fixed?

    Since Apple no longer is supporting the PB G4, you'll either have to find a fan for it on your own or find someone else to work on it for you.

  • How do I turn on the fans on my iMac to keep it from overheating? I used to be able to turn them on when I plugged in the computer and turned the computer on simultaneously but that stopped working.

    how do I turn on the fans on my iMac to keep it from overheating?

    You could use smcFanControl.  That will control the fan speed but be aware the fan is always running.  If you have a fan revving up due to overheating it could be because a temperature sensor is failing.  Try running Apple Hardware Test (on your second installer DVD -- boot with the D key) to see if can detect any sensor problems.

  • My new macbook air 10.7.3 is running hot with the fan blowing just by using the internet. Is there something wrong with the computer?

    My new macbook air is 10.7.3 s running hot, with the fan blowing after about one hour on the internet. It will also run very hot with the fan blowing when it is closed and in sleep mode, is this normal? My macbook pro did not do this.

    My Macbook Pro 15" Early 2008 model had been running hot for a long time.
    Checked Activity Monitor.  (Applications/Utilities)
    AdobeResourceSynchronizer was taking 83% of CPU usage.
    Did a google search and found information regarding AdobeResourceSynchronizer causing high CPU usage and heat.
    http://forums.adobe.com/thread/822790
    Problem seems to be Adobe Resource Synchronizer.app
    To disable go to: System Preferences > Accounts
    Click the Padlock icon, enter password if needed, click Login Items,
    uncheck AdobeResourceSynchronizer
    I don't know how this got install on this computer.
    I suspect Adobe Reader. AdobeResourceSynchronizer.app is within the Adobe Reader application package.
    Control Click (or right click) the Adobe Reader app, click Show Package Contents
    Location: Applications/Adobe Reader.app/Contents/Support/AdobeResourceSynchronizer.app
    Some other Adobe applications may also cause this to run.
    After disabling this in System Preferences > Accounts, temperature seems to be acceptable.
    Also start Adobe Reader X, go to Preferences, Tracker and in the "Automatically Check for New Comments and Form Data", slide the top slider all the way to the right so is says Never.
    After having done all this and restarted the computer, check Activity Monitor again and see if
    AdobeResourceSynchronizer is still running. If it is you can click on it so it is highlighted and click the Quit button in the upper left.
    This solved my excess heat problem.
