My iMac 27" is making noises like grumbling

Well there are air vents on the bottom or the back or both so you would blow compressed air into those areas or when they are changing the drive have the service center do it as it is easier and better to do it when the system is opened up.

  • My IMac just started making noise like a disc is running (there is no disc in it) . Is that normal?

    My IMac just started making noise - it almost soundslike a disc running - but there isno disc in .  Is this normal?

    Probably the fans running.
    Make sure the air vents are clear.

    Your iMac should be almost silent.

  • IMac from 2009. Suddenly making noise like a loud fan.

    My IMac from 2009 is suddenly making noise like a very loud fan, or a little like a vacuum cleaner. The sound seems to becoming from the IMac, not my speakers.  Could this be from any of the wires or connections plugged into it?  Restarting the computer did not stop this. I think this happened once before a long time ago. Anything I can do?

    Before I saw Mike Sombrio's post:
    I restarted the IMac without unplugging the power cord, but the noise was still there when the IMac came back on.  Then I repeated this about 10 minutes later, (restarting the computer without unplugging the power cord). This time the noise was no longer there. I don't know what's going on. I hope this problem does not return. Any explanations? Is this a sign that my IMac is having serious problems? Any advice?

  • IMac external speakers making noise

    I am not sure if this is the correct place for this question...
    but my speakers I have connected to my iMac make an annoying staticky noise all the time. It does this no matter what volume my iMac is set at, but it will go away if I turn the volume down on my speakers. When I plug my iBook or iPod in, the sound is not there. I have replaced cords and tried different inputs on the tuner, but the noise is still there.
    Is there some kind of option for the iMac sound output to fix this?

    Hi Don,
    Griffin made the iFire a few years ago that does just that...connect the Pro Speakers to any computer. Google it and I'm sure you can find one.

  • Fan issue making noise and heating issue

    Hi,
         My laptop fan is making noise like a car engine.Earliar i did nott realize it but since winters are here i can hear it clearly coz ciealing fan is not under use now.Also my laptop is quite heated below.I have read that dust can accumulate in vents but i cant see any.Also my previous laptop got killed becoz of this same issue.Hp should do something about it.Can a layman like me open the dv-4 version and clean the fan? It is out of warranty now and i dont want to spend on shop.But i saw a video HP laptops are complicated to open....and close.Watevr other advice u r most welcome to give regarding yhis issue.
    thanks

    HP notebooks tend to run hot & thermal control is minimal effort in design & materials.
    You can try clening with compressed air or a hoover perhaps but if looks clean & air sems to be flowing I expect it not the main issue.
    You may also want to check running processes & CPU use as issues here & viruses can causes CPU load thus heat.
    Also review notebook placed so vents are not blocked/restricted.
    Use software such as HWinfo to review the actual temps of CPU GPU etc as helps see how much of an issue you really have.
    HP laptops can be improved with thermal shims, ceramique paste, housing vent modifications & in extreme cases secondary case venting 25>30mm fan.
    Not easy to do without some experience.

  • Photosmart 6520 makes noise like slipping gears when printing

    Photosmart 6520 makes noise like slipping gears when printing. Printer is just one month old? Have Windows 8.1 OS.

    Hi @Zed0027,
    Welcome to the HP Forums!
    I noticed that your HP Photosmart 6520 is making noises like the gears are slipping during printing, and I am happy to help!
    For further assistance, I will need to know:
    If the printer is located on a flat surface.
    If there are any error messages displayed on the printer's display screen. Such as: Paper Jam, Carriage Jam etc.
    If the power cable is plugged into a surge protector, or directly to the wall outlet. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector. This applies to Inkjet printers as well.
    If you can see any broken parts in the printer when you open it.
    If the ink carriage is moving freely.
    In the meantime, please try a hard reset, please see this post, How to perform a Hard Reset by @Rich1.
    Hope to hear from you soon!

  • IMac hard drive making a chirping noise!!

    IMac hard drive making a chirping noise!! Its a quiet chirp that goes along with the hum of the hard drive. It doesn't always do it but I'm worried anyways. Has anyone else had this problem? Is it a problem?

    They told me it's likely the CPU Fan - a known issue - and said that resetting the SMU was the first step towards fixing it. I performed that reset, but the crickets in my machine are still alive and chirping. Step #2, as it was told, is to take the machine back to the Apple service center to be repaired. BUT - looking through other threads here on the same issue, it looks like the issue is currently handled by replacing the CPU fan with another identical model and that because the underlying engineering issue has not been fixed, the crickets will return.
    So if this problem is not harmful to the computer, I may be ignoring it for the time being.
    Regarding the recalls though, where did you find the serial number range for the recall? I should check mine against that list.

  • My Imac does not start and make a terrible noise like an alert.

    Please help me, my Imac does not start and make a terrible noise like an alert when try to start ,the Imac keep a grey screen when try to start and keep there.

    Sounds like it is time  to take it to an Apple Store or AASP to be serviced. You can also try troubleshooting using Apple's Gray screen appears during startup instructions.

  • Noise (like a chirping bug) in iMac mid-2010

    There is a chirping / bearing failure noise in my mid-2010 27" iMac, upper left when looking at the screen.  Computer runs perfectly, hardware checks using the Apple provided software, and at the certified Apple repair shop shows no current problems.  I've had the iMac serviced, replaced one faulty fan; I installed a new hard drive (nice, but did not fix this problem).  Using "TG Pro" temperature sensing / fan control app, shows the noise does not change in frequency with any fan changing speed.  Putting the iMac to sleep, the noise stops immediately when the LCD screen turns off; starts immediately when the LCD screen turns on.  I believe that the noise is not a bearing sound, not a fan and not the hard drive. 
    I am now suspecting the LCD or the LCD electronics board.  This morning, I noticed that TG Pro shows the LCD proximity temperature sensor is 20 degrees F lower than all other sensors.  The next logical step is to replace the LCD proximity temperature sensor -- but Apple does not like user repair (I am very competent), so instructions are sparse.  I cannot find where the LCD proximity temperature sensor is, or any vendor who sells one.  That suggests it may be built into the LCD screen.
    It also may not be related to the LCD screen or electronics, and I have (so far) totally missed the source of the problem.
    The noise is driving me nuts.  Any nuts, or notes from anyone's common experience would be most appreciated. 

    Yes it does.  Brighter is louder, dimmer is softer.
    From other threads, I tried resetting the SMC by unplugging the power for a while.  This time, when I plugged the power back in, and turned on my iMac, the noise started immediately before the screen lit up.  Not sure what that means -- changing the brightness correlates with the noise volume does point to an LCD-related issue.
    Thank you!!

  • IMac making noises.

    My imac recently started making a fan noise upon start up that with time can (not always) increase in sound level which = my concern and irritation.  I have downloaded the widget that monitors the temps and fan speed with the following results:
    HD: Mac = 94 degrees F
    CPU = 92                        Optical Drive = 697 rpm
    Heatsink = 94                  HD = 1189 rpm
    Airport Card = 94              CPU = 1198 rpm
    Ambient = 67
    GPU = 112
    GPU Diode = 108
    GPU Heatsink = 104
    In addition I have also done a shut down and unplugged everything for >30 seconds but still the noise returns immediately upon startup.  The computer is not operating poorly, just the noise.  Any ideas, suggestions?  Thank you!

    It MIGHT, just MIGHT, be a software issue. On my iMac G5, if I start up holding down the Option key, I get a loud fan noise all the while, from when it starts looking for drives with an OS on them, up until partway through the launch process after I select an OS. That's obviously a software cause, as it's the same routine that cuases the fan to start then stop, every time.
    While there is a odd possibility of it being a sw issue, what your are describing is not.
    What you are describing is a safety feature. When you are booted to the hardware or test disc (rather than a full system install) the system runs in a very limited mode. Often it does not see or read the data from the temperature sensors. So, what happens is the code on the board is designed to run the fans at a fixed speed that is higher than normal to prevent the system from overheating. An Xserve sitting on a bench running HW tests, with the back end pointed at a cork board, will cause papers to hang upside down the fans run so hard!

  • My macbook pro won't stop making noise! It sounds like the fan but I'm not sure. Any ideas?

    my macbook pro won't stop making noise! It sounds like the fan but I'm not sure. Any ideas? It's really worrying me because I haven't had it for up tp 2months and last week everytime I switch it on it makes sooo much noise. And I treat like an egg so I don't understand whats going on.

    Hey,
    My friend had a very similar issue to yours. The issue came down to the pins of the MagSafe not meeting with the MacBook perfectly causing the lights and the transfer of power to be wacko. I'm not sure if this is issue that your experiencing, but its worth checking out the pins and the MagSafe area on your MacBook for debris.
    Troubleshooting Magsafe power adapters with stuck pins
    If that is all clear, then I would suggest you call AppleCare or take it in to an Apple Store to have it checked out.

  • IMAC fan is making a very loud noise

    Hello,
    Does somebody has similar problem?
    I switch on the iMac and the fan is making too much noise that I can not hear the sound on the computer and the there is a lot of air coming out.
    It is on all the time and I already open a SR with the apple care to repair it, I left the computer for a few days in the apple center but they do not fix it, apple do not care about it.
    I have this problem since I bought the iMac.
    Sometimes it is no making noise it is quite.
    I read that some iMacs have this problem and Apple did not do anything to sort this problem, at least mine was not fixed.
    I bought the Apple care but it is useless because Apple does not want to fix this problem, they said that they were not able to reproduce the problem.
    Any help let me know, please.
    Thank you.
    Maria

    It can be caused because of different reasons: a process which is eating your CPU, a defective fan, a problem with the SMC, etc. First, reset the SMC > http://support.apple.com/kb/HT3964
    If it doesn't work, run Apple Hardware Test > http://support.apple.com/kb/ht1509 This program will allow you to diagnose problems with the hardware of your computer, although this may fail and it may not show anything. When you run Apple Hardware Test, make sure you tick the box to run an extended test. Finally, if you see an error at the end, copy it here and copy it in a piece of paper and take your computer to an Apple Store or reseller, because it indicates that there's a hardware problem with your iMac and it must be fixed
