Remedy fan making noise on Late 2012 27" iMac?

My iMac started making a noticble noise coming from the internal fan about 2 weeks ago and when I'm working/writing it drives me nuts.  I tried blowing into the back vents with a dust remover compressed air can to no avail.  Anyone have any luck making a fan silent again?

NEVER EVER blow dust into a computer that makes an issue worse!!!!!!! If you suspect dust then remove the RAM cover and vacuum out the air intake.
Reset the SMC and PRAM each 3x back to back. If you don't know how please follow the instructions in:

  • In anyone experiencing loud fan noise for late 2012 27in iMac

    I am getting a rattle sould like fan blades (as opposed to the whoosh of air) on my lat 2012 iMac.  Is anyone else having this issue.  It can be quite distracting.  Could it be a hard drive issue instead?

    I have AppleCare cover so I will try to see if they do onsite repair as my nearest store is only about 2 km away.  As I was using the computer last night I heard three incidinces of really loud 'static' noise as well!?!  It went away each time but I managed to record the noise one of the times.  I have included the 'rattle' fan noise also in the links below:

  • Windows 8 on late 2012 27" iMac?

    Hi Guys,
      I m planning to install windows 8 on my late 2012 27" iMac, i read online that people have over heating issues with their macs when gaming via bootcamp. Is that true & is there any issue i should be worried about? The new slim late 2012 iMacs are suppose to be better in cooling, anyone with these new slim iMacs can give me feedback? are the new iMacs handling the gaming via bootcamp better then the old ones? is there any safety precaution i should take like placing a external usb fan near the iMac? feedback would be great.
    Thanks

  • Headphone jack not working on brand new late 2012 27" iMac

    Just purchased the new late 2012 27" iMac. Have tried 3 pairs of headphones, all work with my iPhone but when plugged into back of iMac, they do not show up in Sound>Output as an option. Only internal speakers and Apple TV.
    I have pushed...hard. Not the issue.
    Tired changing Audio Midi settings to 32-bit floating. Didn't do anything...
    Any thoughts?
    Thx

    What you did at last?
    This is happening to me and I'm very disappointed and frustrated!
    Is the first time I tried to use a headphones and the stupid machine doesn't work!
    I already reseted PRAM and SMC also updated OS to 10.8.4
    Is a HW problem?
    Do I have to go to the store and lost ALL the time I already invested in SW install and file moving from my old laptop?
    By the way I can see the light when I unplug the heardphones.
    Before some help desk robot asks, YES, I tried 3 pair of phones ALL of them work well in my Vostro 3550, Samsung S3 and in my Nexus 7.
    Some light here please!

  • Image Persistence On Late 2012 27" iMacs

    Hi.
    I'm currently on my second late 2012, 27" iMac. I returned the first one I bought because of uneven color from top to bottom of the display, as well as a very readable image of my browser's address bar that seemed to not want to vanish from the display against a plain dark gray background every time I closed the browser. It was a persistent image after using the browser for only five minutes. It was pretty bad, and I exchanged the computer for a replacement.
    The replacement model is much better. The colors are pretty even, and if I leave a web page open for a long time, the ghost image on the display generally takes about ten minutes to fade completely away, against the plain dark gray background that I've set as my desktop wallpaper. On my previous model, the image of the address bar never really left. It was, like... permanently burned in.
    I've read an awful lot in these forums about image persistence, and also the help articles that Apple published on this site about it. I'm aware that Apple acknowledges this as normal behavior for their displays.
    I still have a couple of days left, where I can return this replacement unit for another iMac, or get a refund. My question to the community is this: Is what I have now, as good as it gets? I'd hate to take this one back, and exchange it for another that's only the same, or possibly worse.
    Mostly, I'm concerned about residual artifacts from desktop wallpapers, recently closed application windows, etc., interfering with accurate perception of, say, a photo that I open to edit or something. It's a little worrisome. I don't plan to use blank wallpaper forever, or wait ten or twenty minutes after browsing the web before proceeding to work on graphics.

    Although I don't own a imac from reading these forums I'd have to say what you now have is as good as it gets. So that leaves 2 options.
    Live with it.
    Or return it for a refund and move on to some other mac computer or something else.

  • Randomly shutting down late 2012 27" iMac, 3.2 GHz i5 processor.  16 out of 32 GB ram (crucial).  Tried the PRAM and SMC, both did not work.

    Hello,  I have a late 2012 27" iMac.  Its a 3.2 GHz i5 processor.  I originally upgraded my ram to 32 GB and was running like a champ for over a year.  Then, it started to randomly turn off no matter what I was doing.  I took it to the apple store and they said it was the ram.  So I ordered 16 GB of ram from Crucial that matched what they said my computer would need. I got it in last week and installed it and it still turns off randomly. I have tried the PRAM and SMC resets and the computer will run like a champ for 15-20 mins then turns off. I would love any help, advice or possible solutions as I am by no means a computer wiz. Thanks in advanced! 

    Very true - and the tests they do at the store are far better than the AHT. As well, Apple does not tell you where it puts the RAM - they just tell you to add RAM in the empty slots, LOL. Your About this Mac > Memory should show your two modules next to one another (which, as I've decided to "name" them would be slots 1 and 3 as showing from the top as you are looking at it with all the slots facing you (the bottom being towards the bottom of the display). The odd thing (to me) is that the 'about this mac' window still shows the same arrangement even though the modules are now placed vertically. In mine (with two rows of two slots side by side), it shows the OEM RAM in the top and the additional RAM I added on the bottom (which is exactly how the slots are arranged):
    And, one more thought - maybe way off - the late 2009/mid 2010/early 2011 iMacs had problems with adding a full complement of third party RAM (they were ok with all OEM or a lesser amount of third party RAM - that is why mine only has 12 GB rather than the supported 16 GB). There were several very lengthy threads about this; I will try to find one of them which I had bookmarked (I can't find my bookmarks in this new iteration here)...

  • Laptop's Fan Making noise when i use flash

    I am passionate about playing games online, Not that i care about whether or not my computer gets cracked or not, but i am curious now, I want to know why fan of my laptop start making noises and run faster then usual whenever i play games for more than half an hour. I mostly like [various links removed by moderator] and many others.  I just want to know why it happens plus if it can be fixed that would be great.

    I've never heard anything from my trackpad save 'clicks' - and I don't recall anyone else coming here with that problem, either.
    Since it sounds (no pun intended) like a hardware problem, if I were you I would take advantage of your remaining warranty and take the machine to your local Apple Store or an AASP and have them take a look at it. Could be a swollen battery, a bad trackpad, whatever.
    Good luck,

  • Rear fan making noise - is it fixable?

    Greetings, the lower rear fan of my Mac Pro is making noise - a faint grinding noise - as if the motor has sand inside. Since I bought my Mac Pro at an Apple Store, can the tech guys fix it? Or can I fix it? Or is it even worth fixing?

    The lower rear I believe is an exhaust fan to dump the heat inside.  It can be replaced.  Not sure how difficult that particular fan is.  You could add one of the temperature monitor utilities (iStat Pro, iStat Menus, Temperature Monitor, Hardware Monitor) and keep an eye on some of your temperatures if you can live with the sound.  It may get worse or may not.  No way of knowing if or when it would fail, or if it will fail at all.

  • K8N Neo2 Platinum Chipset fan making noises

    Hey all,
    I just turned on my computer and noticed it was making funny noises.  In particular I believe it is the chipset fan making the noise.  I opened up the computer and got as much dust as possible but when I turn it back on continues to make those noises.  How do I solve this problem? 
    Thanks.
    Update: now the fan is barely even spinning.  :(

    Hi,
    You can use the excellent SpeedFan to monitor your PC and to quiet the northbrige fan. I use it an make that fan to run at 70%. It is enough for make it a lot less noise (for me ..). You can also drive your CPU Fan with it.
    But maybe it is another kind of noise you speak of ?

  • Mac Mini (late 2012) vs. iMac (mid 2007)

    I use my computer primarily for video conversion, internet, iTunes, iPhoto, iMovie (occassionaly...too slow), iWork, Office, various other things but NO Final Cut video editing and intense graphics work.
    I've wanted to get a new Mac for quite sometime.  I have an abundance of monitors, mainly HD, just laying around collecting dust, one on a Windows () 8 computer, figured I might just get a Mini.
    I have an opportunity to upgrade from a:
    24" iMac 7,1 (mid 2007)
    2.4 GHz Intel 2 Core Duo
    4 GB Memory
    ATI Radeon HD 2600
    to a:
    Mac Mini MD387LL/A (late 2012)
    2.5 GHz Intel Core i5
    8 GB Memory
    Intel HD Graphics 4000
    Questions:
    1. % wise, how much faster would it take to convert a video of the same format and length? Significantly?
    2. I use AirParrot to send internet video to my Apple TV, tried looking for it (remember seeing it somewhere), can I see my screen or AirPlay it to AppleTV without having to use a HDMI or AirParrot application.
    3. Will I really see a TREMENDOUS amount of performance from the newer Mini in comparision to my old iMac?
    I've read reviews online and have amazing read arguments for and against to the point that my gut is going crazy. Are the benchmarks between the i5 and Core Duo significantly going to reduce my work load.
    Please provide some feedback as I truly appreciate it.
    THANKS!

  • Does Adobe Premier Pro CS6 and After Effects CS6 support the graphic found in the new late 2012 27" iMac?

    Hi there guys! I´m very, very, VERY close to buy a full configuration iMac (the late 2012 27" model) but I have reed in different forums that Adobe Premier Pro CS6 and other applications from Adobe such as After Effects DO NOT support the graphic cards found in the new iMacs....
    is this true??????
    i really wouldn´t understad the logic behid the decission of picking a graphic card that is not supported by one of the leading video editing sofrware used today.... specially when this computer is suppoused to be an Editing Animal....
    I hope this rumor is not real..... then I can be just... really happy and get my new desktop computer and work, work, work, work
    thanks for your attention

    Hi there Daniel, thanks for paying attention to this subject. Today I got an answer from Larry Jordan from his blog (I believe he is one of the "videoguys" from http://videoguys.com and he said that actually adobe does not support those GPU that we will find in the new late 2012 iMacs. However it seems there is a way to make that work out.....
    here is his review on his new iMac, at the very botton you will see comments from people and his answers... one of the last coments is mine regarding this subject, this is what I asked and his answer:
    mGabo Jan 18, 2013 08:50Hi there Larry, I reed in your other post on your iMac that Adobe didn´t support the Nvidia graphic cards found in this model, I have been asking in forums about this and people say Adobe does supports them……Do you know if Adobe now works fine with these cards?
    Larry Jan 18, 2013 11:10When I contacted Adobe about this a couple months ago, just after the release of the new iMacs, I was told that Adobe did not support the graphics card at that time. There is, however, a workaround, which I’m hoping to write up this weekend.Larry
    mGabo Jan 18, 2013 12:28 oh! great Larry! please post the link of that article so I can follow that!many thanks

  • Replace Late 2012 27" iMac stand for Vesa Mount

    Hello
    I purchased the Late 2012 27" Vesa iMac as soon as it came out. Now, I'd like to wall mount it and I see that there's a VESA compatible iMac. I don't want to sell my iMac and buy another one with the VESA adapter. Does anyone know if it's possible to take my currrent iMac to an Apple Service Center and have the stand swapped for the vesa adapter?
    Thanks!

    Not possible unfortunately as the mount is built into the back of the computer...you will have to come up with another solution or replace the machine. I seriously doubt an Apple Store would perform this upgrade but an AASP might, you need to visit one and discuss it with them. 

  • Cannot reinstall OS X on brand new Late 2012 27" iMac

    Using either a flash drive or trying to install Mountain Lion from the store I get the same message that informs me that OS X Mountain Lion is not compatible with this computer. I would assume they have some sort of custom build for this machine currently but this doesn't make it easy to quickly deploy a new machine with a clean install. I am currently using a recovery disk that I made using recovery disk assistant which will work OK but it still doesn't answer why we are not allowed to install the supported OS from scratch.

    The Late 2012 iMac uses a special OS X build that it's not available from the App Store. However, you can erase the disk and reinstall OS X Mountain Lion without any problem. To do it:
    1. Press Command and R keys while your Mac is starting to start into Recovery.
    2. Open Disk Utility, select Macintosh HD in the sidebar, go to Erase tab and erase the disk.
    3. Close Disk Utility and reinstall OS X.
    This issue will be fixed in 10.8.3

  • Late 2012 i7 iMac not waking up and also finding wifi enabled after I turned it off as I use ethernet

    I have a late 2012 i7 3.4 imac with 32 GB ram.  I am finding a perplexing issue and I hope someone may help me out.  I am blessed with the inability to wake my mac up after an overnight sleep intermittently must push power off and then turn on again to reboot.  I noticed since this started that the imac wifi is always turned on when I restart .  i connect via Ethernet (FIOS).  The wifi connection is a extension of my FIOS router wifi.  Will there be any problems with wifi on along with Ethernet connection?  The only software I have on my mac that shows it can work with either connection is CrashPlan. 
    I have no idea how the wifi enables itself as I do not activate it and the icon in the upper taskbar is an empty triangle usually.  This am it was a triangle filled with black lines and when I checked it was enabled.   Any suggestions or tips would be greatly appreciated.  Thank you.

    I've got kind of a radical suggestion, if you want to try it. In cases like you describe a full OS restore, then setting the iPhone up as a new device can fix all these little glitches. It is a lot of trouble, I know, but if you do want to use the service this is one method that should clear it all up for you.
    Thank you, it's good to know that Apple does offer refunds.  I want it to work, if it does what I would like the $25 would be more than worth it.
    I thought clearing my music and starting up iTunes Match with an empty music library might do the equivalent of a full reset... I can't say I really feel like doing that, and I'm skeptical it would clear up all of the issues I've had (play counts, play lists, album art, data usage when I told it to bloody well not use the data).
    Thanks for the input!
