My iMac's fan runs quite loudly.

I only got the computer yesterday from Apple, but it was refurbished. It's an iMac 21" 2.7 1TB.

When you say that the 'fan runs quite loudly' do you mean that the fan is making an unusual noise such as a buzzing or clicking sound, or do you mean that the fans sound like they are running at full speed?
If the fan is making a buzzing or ticking noise then that could indicate that something is touching or rubbing against the fan. If you just purchased the iMac then I would contact Apple to arrange for a replacement.
If the fans sound like they are running too fast then it could simply need an SMC reset. To do this, power down the iMac and then disconnect the power cord for ~15 seconds. After 15 seconds plug in the power cord while making sure you don't press the power button. Here's an article that provides additional information on this condition and why it occurs.

  • FAN RUNNING VERY LOUD

    I am wondering if anyone has had or heard of the fan in a 24" iMac suddenly running quite loud? My computer is a year old and today I turned it on and it sounds like a desktop DELL!! The fan is so loud. Is this an ugly monster rearing it's head? or is this a minor issue that might go away?
    Please help.
    Cheers

    It probably means the computer thinks it is overheating. Maybe it is overheating. As Miriam suggests, intense computational activities generate heat. Possibly dust has accumulated on the inside, or where you are positioning the computer is blocking the flow of air. If the software that controls the fan is not working properly the default mode is to run the fan at full speed. Have you run disk utility to verify your drive to check all seems okay?
    Alternatively the computer just thinks it is overheating. There are also hardware analysis tools that come on the disc with your Mac.
    There's third party utilities that report temperatures, but Apple says you shouldn't reply upon these, and take your computer to a service center.
    This isn't one of those liquid cooled CPUs is it? There was a post about one of those overheating recently and the guy found the coolant had leaked and left a puddle under his computer.

  • Why is my fan running so loud?

    I purchased my 13" macbook pro about 2-3 weeks ago, But have noticed just recently my fan running quiet loud and constantly. I have done two smc resets that didn't change anything, checked my activity monitor to find nothing wrong, and checked my exhaust rpm and temperatures which were perfectly normal. Does anyone have any other information that would help me fix this frustrating problem?

  • Satellite A300D - Fan running very loud and notebook is getting very hot

    I was wondering if anybody could point me in the right direction as what to do with the overheating problem i currently have with my A300D. I have had the laptop for under a year so it is still under warrenty but i am not sure where to go or what to do in order to repair it.
    The problem: Around two months ago I noticed the fan running very loud and also the laptop becoming very hot. Now it runs so hot the laptop switches itself off completly. The heat being fanned out of the laptop is so hot! burns your my infact.
    Has any one any advice they could offer me.
    Thanks
    James

    Hi James
    You wrote that you have the notebook under a year so my questions is did you already clean it?
    The notebook should be cleaned every 3-4 months and I do this every 3 months. Every time I do it Im wondering how much dust comes out and after this procedure the notebook is a lot of cooler.
    Here is an interesting Toshiba article about this:

    Compressed air spray is really useful and you should check it yourself!!! ;)

  • 27'' iMac fan running very loud?

    I recently had to have a logic board and a video card replaced under Applecare, (get it, I have always needed my iMacs fixed). I have 'Carbonite' installed as backup. My activity monitor (when Carbonite is running) is showing that Carbonite is really working the 4 cores of the processor. Between 75 and 99%. My fan NEVER ran really loud before on this iMac, or my last two iMacs. I have used Carbonite as a backup for the last three years. The reason for the logic board and video card burning up MAY have been that the fan did NOT come on.
    I'm going through a lot of phone calls with Carbonite to see if they have any answers. In the meantime I'm disabling Carbonite. So far the loud fan is not coming on.
    Does anyone else have the problem of a very loud fan running?  And why do you think that is?

    Hello, let's see some temps & fan speeds please.
    Get Temperature Monitor to see if it's heat related...

  • MB 13" late 2007 - fan running really loud

    Hi guys!
    I've tried to find a solution to my problem around the web, but I didn't find anything what could help. My old MacBook from 2007 started to get pretty loud recently. What I realised, fan is turning on while I'm running internet browser (doesn't matter, Safari, Opera or Chrome). But when I watch a movie, even in 720p, the fan is quite. I don't have much apps on my MB, and I try to run CleanMyMac from time to time.
    Is my MB just old (that is a pretty obvious answer), or I can do something to fix it?

    There could be a few things going on to cause the symptoms, the fan and likely excessive heat.
    If the hard disk drive is relatively full and has little or small available free space, the computer may be looking for places to put swap and temporary files the OS uses, to include those when the OS uses free space as Virual Memory. This would mean more read-write cycles to the hard disk drive, if there isn't enough RAM.
    Also if the hard disk drive is getting older and worn, it may be slower and the processor among other things are adding up and generating heat so the fan runs more. An early model MacBook may be a candidate for a larger capacity hard disk drive, & if it doesn't already have it, an upgrade in chip RAM capacity to the max it can use.
    There may be a reset, such as SMC (system management controller) that may help. In some cases, though the NVRAM/PRAM reset helps. I had to try both on my MacBook when it seemed the processor cores were alternatingly hotter than spec but without a load. In this case, I suspect my MacBook may need the thermal couple to the heatsinks removed and new thermal paste applied, so any heat may be transfered faster. I used a free utility called 'temperature monitor' that includes temperature monitor lite, a download. It works OK once you figure out the settings, and choose to install extra stuff for intel cpus.
    So there are things that could be done, depending on the cause of the symptoms. Going through the long way may include unproductive steps when 'trial & error' is involved, so hopefully there is a shorter recipe.
    Good luck & happy computing!

  • MacBook fan running very loudly

    I have been having issues with my MacBook overheating and causing the fan to run very loudly (so loudly I can't listen to music or watch videos on it very well). I have had the motherboard replaced twice this year alone by Apple and I still have coverage till November of this year. They told me if I keep it on a flat surface (like a desk), the problem shouldn't keep happening. More times than none, I only have one application running like Safari or Firefox with only one page open and still the computer is incredibly loud. Any suggestions? I really do not want to take it out to a retail store again unless I can get a new MacBook out of it since it'll be the third time the motherboard has been replaced.

    Hi Brandon: This is a shot in the dark, but check out the troubleshooting tips in the Apple article below.

  • Mac fan running too loud after update

    I have a Macbook pro 13".  (mid 2012)
    Memory: 4 GB 1600 MHz DDR3
    Processor: 2.5 GHz Intel Core i5
    Storage: 500 gb
    After updating to Yosemite 10.10, my macbook pro's fan is running too loud and producing a lot of heat. I reseted the SMC several times but it didn't help. Surprisingly, The fan also runs loud even if only 1 application is open.
    Please advice me what should I do.
    Thank you in advance!

    I have the same model and I've had the same problem for a few days. I didn't really have problems with heat, but my fan was going crazy even though I was just browsing the Internet. Maybe you're logged into iCloud and have some activity going on. What worked for me was going to:
    1. System Preferences
    2 iCloud
    3. Uncheck things like "Keychain", "Find my Mac", etc. (things you don't need/use)
    For me, I unchecked everything and logged out of iCloud. After several minutes, my fan is super quiet and not acting up! Hope this helps.

  • Fan kicks quite loudly every minute on Satellite L30

    Hi,
    I'm using a Satellite L30 laptop. One thing I am finding annoying is that the fan kicks in quite loudly every minute or so, then quietens down for a while. Using a temperature monitor it looks like the fan kicks in when the temperature rises above about 50, then slows down as it falls. When the temperature is below 45 the fan stops altogether which causes the temperature to quickly rise back above 50.
    I want to change the power management settings so that the fan stays on quitely at lower temperatures. I have a desktop computer where it is possible to change the fan settings in the BIOS, but I can't find anything like this on the laptop. Can anyone suggest where I should look - are there any open source or shareware tools which will do this?

    Maybe you should check this topic: http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=18258
    The trick:
    1. You need in Power Saver the performance profile, that uses performance fan control.
    2. You need to make another profile (for example called Silence). In this profile you need the optimized battery fan control, the other options doesnt matter.
    3. Then, you must activate the performance profile, and wait, until the fan speed raises (begins to cool down the CPU). Meanwhile the fan speed is high, you must speedily switch to the silence profile (with the Fn+F2 combination you can choose, which you want).
    4. And voila, the fan rolling remains on medium (not noisy) speed so long as you turn off or hibernate the computer, and the temperature drops to 40-50 degrees.
    This trick works only if you use Windows XP, because Power Saver doesn't work under Vista. (I have Satellite L30-134, BIOS number is 2.60.)

  • Is the iMac G5 fans running at incredible speeds safe?

    My iMac G5's fans are running at an incredible speed whenever I start from the Apple Hardware Test CD or when I enter Single-User mode. When the fans run in this fail-safe mode, is it safe?

    Perfectly safe, in both cases the fans are not controlled and this is normal.

  • My iMac G5 Fans run at full speed when using regular everyday applications.

    When using just normal everyday applications such as using about 30 min of Safari to surf the web or maybe something else, my fans run at full speed. I have just got a new logic board replacing my old faulty one. How can I fix the fan problem?
    Thanks!

    Hi again Miriam,
    With more news for you and iMacG5 on the fans go crazy. I just got back my computer from the repair center. After more than a week under observation, the technician told me that they just couldn't replicate the problem. They had the computer running non-stop during all this time, not even allowingit to go to sleeo mode and nothing.
    The CPU fan never went beyond 2300 rpm (or so) and never went to sleep mode on and off by itself. Furthermore, they ran all possible tests and everything comes back as OK.
    Right now I have a movie running on the background, together with a photo processing software open and other smaller processes and the CPU fan is running at 4361 rpm !!! the temp of the CPU is 66.3 Celsius.
    Any thoughts??? It's really making me crazy because the computer was neverlike this and now it sounds like a hair dryer. I emphasized with them the fact that this just started after they changed the logic board and as coincidence after Ioaded the security update 2006_04. The technician told me it may be software related. If the computer doesn't go to sleep by itself, then he recommended to reload the operating system.
    Any comments appreciated.

  • IMac G4 Fan noise very loud, excessive speed

    Hi there

    any suggestions or solutions?

  • IMac cpu fan running at full rpm

    hi all
    A few days ago my cpu fan started running flat out. I have done the smc or whatever it is caled reset thing where you unplug the cored ect.
    I have done the hardware test with no bad results.
    I have checked activity monitor for cpu usage and there is nothing unusual there, so I can only guess that the cpu temp censor is faulty.
    I should also add that this machine has been running non stop since mid 2007 , with the exception of the odd blackout and restart, thats pretty amazing i think.
    maybe its time has finally come ;(
    any clues ??
    thanks

    SMC is firmware and OS X is software, which has nothing to do. Furthermore, you are using a very old iMac, so SMC should not have been updated with OS X 10.10.2.
    If you have tried a SMC reset and it did not work, run Apple Hardware Test (make sure you choose an extended test) to see if there is any problem with a temperature sensor or anything like this -> Using Apple Hardware Test - Apple Support
    Note that you may need the DVDs that came with your Mac in order to run it. If you get an error at the end of the test, please copy it here.

  • Fans running really loudly?

    Recently when i was using my macbook pro, the fans seemed to go into overdrive and started making really loud noises, the noises sounded like it was rattling slightly. I didn't have any strenous programs running, just pages and google chrome, but the sound persisted until i put my computer to sleep, then it stopped. Right now it is queiter, but what should i do to avoid this in the future?

    If your fans are going crazy when you aren't loading the system, then something is wrong. Try an SMC reset. And to make sure some background process hasn't gone wild, run Activity Monitor (from Applications > Utilitites) and select All Processes - anything suspiciious running over say 10%? (You can sort by CPU% by clicking on the column label.)

  • IMAC G5 fans running at high RPM

    Hello,
    I have a 20" G5 iMac and just had the motherboard replaced under warranty. Since the replacement my fans will start to run at very high rpm's fr no reason. It will happen even when the computer is not being used and no applications are running. It is currently at:
    CPU 122 degrees
    CPU fan 2996 rpm
    HD 124 degrees
    HD fan 4178 rpm
    System fan 3098 rpm
    I have called applecare and they had me do several resets which seemed to help for about 1 hour and then the fans have ramped up and not gone down in the past hour. This last time I was watching TV and heard a noise from the computer and low and behold it was the fans. Nobody was working on the computer and all apps were closed. I bought this computer in September 2005 and have had 2 lcd's replaced and a logic board replaced. I am getting frustrated with this, my first, Apple computer. Does anyone have an idea of why the fans are running so high? I never had a problem like this with my old logic board.

    Have you looked in Activity Monitor to see if any applications are causing the fans to run? Applications/Utilities/Activity Monitor.
