HELP. New IMAC loud fan

Just recieved my 2011 imac i7 with 16 Gb of memory running on Lion. The fan right out of the box , with only the apple software pre installed is extremely loud and runs constantly. What do you all recomend i do at this point? I will be utilising this for heavy duty graphics and motion.Very dissapointed.Should i cut my losses on this and return for a Mac Book pro instead as i am reading about a fan problem with these Imacs.
thanks-Kev

All the fans run constantly. But if the fans are very loud you should get the unit replaced while still within the 14 days from purchase.

  • IMac Loud Fan: getting error 4SNS/1/40000000:TCOH

    My BRAND NEW imac 20" has been making all sorts of noise. The fan revs up to full rpm and doesn't quit until I restart and zap the pram. After runnin some the hardware diagnosing app i get the following error:
    4SNS/1/40000000:TCOH
    What the heck is that?

    Your computer has to start from the Windows disc but it's not doing this. After creating the volume, make sure that the Windows disc is inserted, and turn on your Mac holding the Option (Alt) key, so you will see all bootable partitions. Choose the "Windows" option with a DVD, so the Windows installer will start and you must follow its steps.

  • Help - new iMac 5k not displaying retina resolution after migration from older iMac?

    Hello all,
    I have just recently purchased and started up a new iMac 27" 5K iMac.  Upon startup I took a look at the display settings to play with the different options for optimizing screen real estate.  I noticed that the default setting for the new iMac is labeled as "default retina" and when you mouse over this setting a line appears that says "looks like 5120 x 2880".
    An hour later I migrated my files and settings over from my previous iMac (27" late 2012) but noticed that when I go into display preferences it no longer has exactly the same options.  Now the default setting is simply listed as "default" (not "default retina" as before the migration) and the line that appears states "looks like 2560 x 1440", which was the resolution of the older iMac.
    I am unable to figure out how to revert back to the retina display options.
    Has this happened to anyone else?  Your help is much appreciated.
    Thanks,
    Warren

    The warranty entitles you to complimentary phone support for the first 90 days of ownership.
    If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

  • Does new iMac have fan? Is it noisy?

    Does the new iMac have a cooling fan? Is it noisy?
    Thanks,
    Edward.

    It certainly does. IIRC, there is a cooling fan for the processor (there must be one nowadays), one for the optical drive and one for the hard drive, plus maybe one for the graphics card (I'm not sure about this one). I get this info from the disassembly photos of the new iMac.
    I don't have an aluminum iMac, but if you search the forum you'll see that most people say it's quiet, maybe even more than the previous Intel iMac (which was reportedly much quieter than the G5 iMac).

  • [help] new iMac +tiger

    Hi,
    I purchased a new iMac (24inch, 2.8ghz core2duo extreme,came with leopard) a little while ago for use with music production (pro-tools, ableton live etc.). Before this I had purchased a MacBook Pro (running tiger) for use with DJ'n and production on-the-go, making the switch from Xp.
    I originally had the iMac setup with bootcamp running Win XP pro, allowing me to keep the programs I had previously used and slowly move across to a full Mac set-up.
    What I didn't realise is that leopard is unsuppported still by Digidesign for my soundcard and Pro Tols LE, and most of my plug-ins are unsupported aswell. This means my MBP and Desktop aren't running the same software, so if i work on a track on my laptop , I can't move it across onto the more powerful computer which is what i was intending to do.
    Anyway I decided I would try to install tiger on my iMac, so I backed up necessary files on my XP partition and used bootcamp to delete it,which somehow messed up my leopard partition aswell, leaving me with nothing.
    Now I have leopard re-installed and am wishing to install Tiger on it. I have used a program call CheckUp, which tells me that the computer is capable of running tiger and I have the tiger installation disk (boxed version, but it is for PowerPC only). I have read about succesfully installing tiger on a new model iMac (through using the iMac as a firewire drive from my MBP) but am unsure how to get the correct version to work on the iMac, as it seems it needs to be updated before it can be used.
    here is the link to what I had read on it http://discussions.apple.com/thread.jspa?messageID=6887285
    Any help with this would be greatly appreciated.
    Thanks,
    Shane

    You cannot install the PPC version of Tiger on it you need to find an original 10.4 ALU iMac install disk. http://discussions.apple.com/thread.jspa?messageID=6701696&#6701696

  • Help - New iMac, Time Machine backup issue

    Hello everybody,
    I am a happy camper with my brand new 27" iMac, however... I have a problem with system migration. Here is the issue:
    - On my Time Machine, I have backups of my old iMac and my MacBook Air
    - When I tried Migration Assistant to reinstall my old iMac contents on my new iMac, no backups were found
    - Then, when I disbaled the Time Machine on my MacBook Air, I could see the MacBook Air backup in the Migration Assistant.
    So, my conclusion was: I need to disable the Time Machine on my old iMac too! However - that one is BROKEN.
    How do I proceed??? Migration Assitant keeps telling me that not all copies can be restored because some systems still seem to be mounted... or something similar.
    How do I make my Time Machine forget about the old iMac? Yes, I can see the Time Capsule in the finder, I can even see the contents of my old iMac backups, but Migration Assitant won't eat them...   
    Your tips are much appreciated.
    Maccer. 

    Thanks Toad, I did that. Unfortunately I could not find an anwer to my problem there. All I can do now is retrieve individual files, which is a hassle. I want full system restore, including all my files, email etc.
    The Time Machine keeps telling me that "another system is mounted"  and that "not all copies can be restored".
    Since I can SEE the full backup file, I cannot imagine it is hard to use that file for Migration Assistant.

  • I turned on my new imac for the first time and it is making a loud fan noise please help

    I just got a new computer and when I turned it on for the first time it started making a loud fan noise. the noise seems like it is coming from the back speaker. and it does not make the noise on sleep mode.

    Connect the iPad to a USB 2.0 port your computer with the cable and iTunes should launch and it will take you through the process step by step.
    I assume that your computer meets the requirements and that you have the latest version of iTunes on your computer.

  • My new Imac 24", 2.8GHz Intel Core is suddenly making a loud fan noise

    Please help!
    This Imac is only a week old. I bought it on apple online store. This is 24" 2.8GHz Imac and it's been the best computer I've ever had. It was wonderful to work and silent until yesterday. And suddenly I can't stand the fan noise coming from my new Imac. I downloaded i-stat Pro to check the status of my computer and it reads *CPU fan:1198rpm, hard drive:1198rpm, optical drive: 4401rpm*
    what is wrong with my computer?
    I searched many mac forums, and I've tried many things including shutting it down and unplugging everything and replugging everything after a while, but nothing solves this problem. Does anybody have experienced this problem? I am not even using many applications. I am only using safari, and the fan is at full speed. SO LOUD! What can I do to solve this? Should I take it to apple to look at it?

    Hello lovingimac
    Welcome to Apple Discussions
    That sounds like there is something wrong with the temp. sensor for the optical drive.
    If carefully following the SMC reset instructions below, does not fix the fan issue:
    http://docs.info.apple.com/article.html?artnum=303446-en
    Then yes you need to make a trip to your local Apple service center.

  • The fan on my brand new Imac Quadcore is blowing extremely loud. Is this normal

    The fan on my brand new Imac Quadcore is blowing extremely loud. Is this normal?

    I have the same problem on my 2010 IMAC 27" I7. Even if the mac is running at idle it occurs. It was already at the apple store for repair.
    Later they told me, they found nothing with the hardware test so its not their problem?!!!
    the activity monitors shows also nothing special, even the cpu's are at idle. No streaming or rendering, just working on the web or some normal documents...
    I runned smcfancontrol to check whats going on. It seems that the onboard temperature sensor is measuring wrong instantly so they SMC thinks, its to hot/or not and then spinning up the fans to full power.
    SMC reset is not really working, or just for some hours.
    Can anybody else help?
    Thx

  • Clicking noise, random loud fan, brand new macbook help?

    Ok. Here goes:
    Just bought a new macbook 2.16, with 2 gigs of ram from an apple store on Friday. I notice that about every twenty seconds I hear clicks that sound like the harddrive is thinking, followed by a slightly louder fan, and then just as suddenly the louder fan goes away. I downloaded IstatPro and my fan would hover around 1799 but constantly go from 1795 up to 1805.
    What's strange is that when it gets louder, I don't hear it go up to speed like my Imac used to do, and it's not a higher frequency but sounds like something that was in front of the vent kind of jumped to the side, and now it's just louder.
    It's annoying. I would much prefer a constant 1800 whir which is actually quite pleasent.
    Let me know if this is normal fan activity. Or any idea of what this could be. Besides that the computer is running great. I'm going in on Saturday and possibly asking for a new computer? Just now afraid that I might not get something better. Also the box the computer came in was really dirty, and a little banged up. Do they used recycled boxes, or could I have possibly got a previously owned unit? Thanks. sorry for the long post...

    ... we've got the same machine. mine's a month old; it sounds exactly as you describe. the fan noise increases with cpu load, and on mine doesn't start to bug me until around 3,000 rpm and gets real loud ~6. the last laptop I had, a win machine, was absolutely silent until I saved to the hard drive or opened a new program. the keyboard was silent too. so I got spoiled. I did about a 100 page search here and it seems common for the macbook to run noisily and hot. I haven't been able to get a definite yes or no from any genius or tech on whether the fan is designed to ever shut off, but from what I've found out, I would guess not. The cd/dvd drive crunches and clunks when it grabs a disc (there's a recording of this on the apple site indicating it is normal)and when it spins up, sounds like the machine will lift off the desk -- which I have read other users say.
    take an hour and search here. between user comments and moderator replies, and the apple tech docs, there's a lot of info.
    hope that helps.

  • Loud fans in sleep mode 20" G5 iMac Rev A, OS 10.4.11 New Info

    This is more of a confirmation and heads up on a problem I encountered and solved to see if any of you have other ideas.
    Several weeks ago I replaced the power supply bought from Mac Pro Online in my G5 iMac. When I put it to sleep I hadn't noticed anything odd at first because I'ld just walk away until one day I could here the fans going full blast. The screen was off as usual but the sleep mode light wasn't on while the fans were running. I waited about a minute until the fans returned to normal speed and the sleep mode light returned to its usual behavior only it seemed to be a lot brighter.
    I awoke the iMac from sleep and all was fine. I put it back to sleep and the screen shut off as usual but the sleep mode lights wouldn't turn on. I waited about a minute and listened to make sure that the iMac hadn't shut down and then the fans started up full blast for about 30 seconds and then returned to normal and the sleep mode lights turned back on.
    I shut the iMac down, disconnected all USB and ethernet cables and reset SMU using the unplug power cord, 10 second wait, replug holding down rear start button. Fixed it!
    Swapping out USB devices I narrowed it down to a Kingston USB Multi-sized port memory care reader hub-part number: FCR-HS219/1. I tested and got repeated results described above reconnecting it and downloading some images and ejecting. Loud fans in sleep mode happened again.
    Tried a MobileMate Memory Card Reader, downloaded images, ejected and no problems with sleep mode.
    My question is what could've messed up the Kingston Card Reader? It was working fine before the power supply replacement.
    Thanks,
    Tim

    There's no telling.
    Only cause that came to mind is a lightning hit last week that sounded very close by where all it did was cause the lights in my home to blink. The computer didn't. However, this might have fried the Kingston card reader.
    To give an idea of the resilience of the former power supply, about a year and half ago I had the back off with the iMac sitting upright on a towel on the table while I played a YouTube video to see if I could cool this thing down. Instead of cooling it I overheated it by blocking the vents to where suddenly the iMac just shutdown. I could detect a strong smell of melted plastic from the power supply.
    Put the iMac back on its stand and restarted without a hitch and I've never had any problems until several weeks ago when it just started shutting down for no reason. It passed the LED light test as it still does now with the new power supply.
    This is the first Mac out of three I've had since 1998 that allowed me to see odd behavior like this. I had to rely on my 2000 Pismo G3 PB to find a replacement PSU online. That thing never breaks.

  • IMac 27" (Late 2012) Loud Fan and Overheating Issues, causing Hard Drive Failure

    Hi all,
    I'm having some serious overheating issues with my new iMac. Any help to help me solve this problem would be gladly appreciated since it's really beginning to bug me. Here's what's has happened:
    I noticed in the first few hours of switching the iMac on that there was a short burst of very loud fan noise. This has been happening about once every two days since and every time I haven't been doing any heavy processing with the system. I've noticed that the main fan will spin, on average, at 1200rpm. Is that normal? The iMac is very well ventilated and sits right next to a window...
    I have also boot camped the iMac with a copy of Windows 8 so I could run some fairly power-hungry games. I intentionally purchased a high end iMac (27" display, Intel Core i7 3.4GHz, Nvidia GeForce 680MX Graphics, 1TB Fusion drive) and expected the iMac to run games flawlessly. However, after a few days, I noticed that the CPU and GPU had shot up to a worrying 80°C whenever I ran power-hungry games, with a very loud hissing noise from the fan. After running games for about 10 minutes, the fan will stop hissing, causing the GPU and CPU to increase to 100°C. The iMac then fails and switches off unexpectedly without any warning. After analysing the Windows event logs, I received an event ID 41: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.
    As this occurred about six times whilst I was testing my iMac's performance, I think my hard drive has now begun to fail - sometimes I will hear the hard drive make a click noise, about once every 5 seconds. Sometimes, the clicking noise causes OS X and Windows to run very slowly (even though minimal RAM is being used and nothing too intensive (Safari, Mail etc.) is being processed). Running Repair Disk and Repair Disk Permissions under OS X's recovery mode as well as a repair in chkdsk in Windows suggests that there were no problems with the hard drive. All I can do is wait a while for the clicking noise to stop, and then performance will increase. I have backed up everything externally.
    I have also performed a reset of the SMC as well as the PRAM, which hasn't really helped.
    Any help will be appreciated. I will gladly provide any extra logs etc. if they're needed.
    Thanks so much,
    Alex.

    That's the default fan speed on iMacs, so there isn't any problem with this.

    You must know that Boot Camp isn't compatible with Windows 8 and that Apple hasn't released drivers for Windows 8, so it can fail. Install Windows 7 inmediately until Apple launches updated drivers.
    As it looks like the hard disk is damaged, I would take the Mac to an Apple Store. It's in warranty, so it should be repaired for free or you should receive a new one

  • IMac G5 keeps freezing/crashing. SMU reset resulted in a loud fan noise.

    I have a refubished iMac G5 OS X 10.6.8 desktop that was purchased in Aug, 2006.  Recently it has been either freezing, shutting down completely, or the display will just shut off multiple times per day 20+ times/day.  I am not interested in purchasing the $49 help from Apple.  Is it time for a new computer?
    I've been attempting some troubleshooting:
    I have plenty of RAM- we installed more memory about 8 months ago.
    Temperature running at 40 degrees C
    I reset the SMU but now am hearing a loud fan sound and there is air blowing out of the horizontal vent in back of the desktop- which does not typically happen.  The computer has not crashed since I reset the SMU 20 minutes ago.  I'm worried about the noise.
    Also, it has been really hot where I live, with a heat index of 110 today and I don't have air conditioning.  Current indoor air temp is about 86 degrees F.  
    Also, I have been seeing thin horizontal stripes across my screen for the past few months, related or unrelated issue?
    Thanks for the help!

    Not that this will cure it but it may help:
    As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
    You are now in a perfect position to do a
    SMC RESET
    http://support.apple.com/kb/HT3964
    Shut down the computer.
    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    It is the 5 second timing that initiates the reset.

  • 17" iMac G5 2GHz (ALS but no iSight) runs hot and LOUD fans

    Hi all,
    I love my iMac. I've had it for nearly 8 months now. From day 1, I've been surprised by how loud it is under any significant CPU load. Unfortunately for me, I have waited until I'm well out of my phone support window to do anything about it. I have not yet purchased AppleCare.
    As I type this, my CPU temp is 70 degrees C and fan is running at 2600 RPM, running nothing beyond the browser in which I'm typing. Should I attempt to work in iMovie and render said work to DVD (the reason I bought the machine), CPU temp will climb to ~76 and fan speed jumps to 4600-4800 RPM. At this speed, the noise is unbearable...but it is annoying even when idle.
    Can any of you with this model of 17" iMac comment on your experience? Do these numbers and this experience sound normal? I know I'm not alone in this complaint, but I can't tell how widespread the problem is or whether my machine is normal or defective. I've been told by my local service center (CompUSA) that every single 17" iMac of this revision runs hot and has loud fans, and that there is nothing I can do short of complaining to Apple in the hopes of getting a replacement of a later revision. I was told by a "genius" at a different Apple store that my machine sounded about like he'd expect.
    I'm getting a system board replacement tomorrow, but have been told not to expect it to make a significant difference. I figure I must do it before Apple would consider further action.
    Any advice at all will be greatly appreciated. Sorry for the long message...
    Thanks,

    iMac G5 17" Mac OS X (10.4.5)

    Mine is still fairly new as I picked it up off ebay a couple weeks ago brand new. So I don't know when it was actually manufactured. The part of the noise that gets under my skin is that soft but constant background whining coming from the CPU fan. It doesn't really sound like anything rubbing or a bad bearing, just the sound that an electric motor makes. But, it just seems to resonate from the lower left hand side where the air intake is.
    So quite accidentally one day I held my hand under the left hand side and it completely muffled the whine sound. You could still here the hum and the sound of air but the irritating element was gone. Playing around a little more, I opted to tape a business card under that lower left hand corner, bridging the gap from front to back to still allow an airspace for the fan's suction. It knocks out about 90% of the whine.
    It's been running that way for two weeks with no ill effects. Yes, the fan speeds up and slows down when needed. Normal at rest RPM is 1500 and mid to upper 50's on the temp. The highest temp I've seen under max continuous load is 65 with the fan at 4000 rpm.
    I did experiment with something longer than the business card but I did then see a decrease in cooling capability. The isight models have their suction ducted out the back and I bet that gets rid of that resonance.
    So all in all it still makes less fan noise than my old B&W, it's just that the B&W wasn't up on the desk so close to our heads. But, If your fans are constantly on high, there is a procedure for resetting something in power management, I just can't find it right now. Hope this helps.
