I'm completely confused. The iMac is hot? It's cool? I don't think we know yet it's a G5.
Anyway, if it's an iMac G5, for the fans try an SMU reset.

If it's not an iMac G5, Google "SMU Reset" for your model.

  • Imac shut off and the fan is really loud...

    I have an iMac 27" i7, 16 gb ram. The screen randomly shut off and the fan became really loud. Tried turning it off and back on, but still did the same thing. Tried resetting the PRAM, heard the chimes, but then did the same thing. Is it overheated?

    Check it. Install an app like iStat Pro to check the temperature, and post it here. There are different temperatures (CPU, hard drive, graphic...). If you want, just take a screenshot of the widget (holding Command, Shift and 4 keys, and selecting the widget) and upload it here, pressing the photo icon at the top of the reply box.
    Apart, you should run an Apple Hardware Test extended test, to check if there's any problem with the iMac > http://support.apple.com/kb/ht1509 If, after running it, it shows an error, copy it here, because the Mac has got a hardware issue

    If you bought the product in the U.S. directly from Apple (not from a reseller), you also 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.

  • 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.)

  • Does anybody have problems with the Macbook Pro Retina 15' fans being really loud even when playing flash games like candy crush or tetris?

    Hey guys,
    So after a few months of using the MBP 15' Retina, I've discovered that the fans are incredibly loud even when playing flash games like candy crush or tetris.. are any of you guys having the same problem? Like all of a sudden from be quiet to unbelievably loud just as the games load. So yeah, hopefully someone has the same problem as I am having.
    What I was thinking was that the MBP Retina 15' is such a beefed up laptop, it shouldn't require that much CPU to run flash games that are not even THAT graphically intensive to which making the fans that loud..
    Thanks!

    Believe it or not, Flash REALLY isn't the issue.
    It's hardware makers making devices with less processor performance and requiring software makers to fit into a certain requirements of such. Namely iPhone, iPods and iPads.
    Flash is designed to give a lot of features and work across many operating systems, browsers and platforms as a write once solution.
    Flash has a certain level of processor performance requirement, which hardware makers like Apple want to build less powerful machines using less expensive processors.
    Apple has removed Coverflow 3D effects from iTunes and discontinued the 17" MacBook Pro, leaving only the 15" as having a more powerful 3D capable graphics capability.
    So Apple is obviously on a anti-heat/performance quest as they further thin up their hardware, trying to kill Flash by punishing Mac users who want to run it.
    Flash runs without a fan sound on my older Mac with dedicated GPU and older OS X verison, no sweat.
    Head to your System Preferences > Energy Saver and if you have it, uncheck Automatic Graphics switching, this will use the dedicated GPU and shorted battery life, but if your on power should reduce the heat and fan noise.
    Another option is to use SMC fan control and set the fan default speed slightly faster, this will keep the machine slightly cooler and not trigger the higher fan speed as often.
    If your running 10.8, you will need to System Preferences > Security > downloads to "Anywhere"
    SMC FanControl is over at MacUpdate.com.

  • The fan gets really loud sometimes

    I just bought my Mac a couple weeks ago, not more than a month ago, and I haven't really downloaded a lot onto my computer. But sometimes the fan comes on really loudly, like it's having a hard time cooling the computer. Granted this happens usually when I'm on a site or using a program that is graphic intensive, but it only started doing this sometime this week. Could there be something wrong with the computer?

    Your MacBook is behaving as it should. The fan will come on when the CPU is working overtime.
    You can run Activity Monitor in the background and see what processes are consuming CPU cycles when the fans come on.
    It is Abode Flash more often than not on a website that gets the CPU working hard and the fans going.

  • MacBook fan blows really loud for 5-20 sec.

    hi guys, I hope you can help me with my little problem. I started my MacBook a few days ago and I notice that my fan blows really hard at non working procceces. he blows 5-20 sec. very loud as if he must work very hard. I will open my Mail and it's sound like my mom turning the hoover on. I have a CPU utilization of 5%.. do you have any idea? it is not syslogd, I checked it.
    *I changed the backcover from my mac. it was a Apple exchange reaction.

  • Fan noise - really loud - HELP

    Hi, everyone!
    I have a MacBook Pro 13'' from mid 2010, with OS X Maverick installed.
    Recently, my mac started to make an annoying noise from the fan...
    Check the noise in this video: https://www.youtube.com/watch?v=yWDuecRdn7I
    I've tried to clean the fan, but i don't have the Torx Screwdriver to open it completly...
    But I really don't know if this noise comes from the fan because it's dirty or because something else...
    I really like to solve this problem, cause sometimes it gets really loud, and i can't even concentrate on my work...
    My computer is really nice, 0 problems untill this time...
    Best regards,
    Pedro Couto   

    Yes, your fan assy. is about to fail to be certian
    Dust bunnies
    Your Macbook’s cooling system, including fan and rear vents pull cool air in from the back and (in the case of the Macbook pro) also from the left ports bringing this air around the processor, GPU, and heat sync and blow it out the back, as such your Macbook acts like a little vacuum cleaner of the air around you. If you use your notebook in a dusty area or around a lot of pet fur, this can quickly, even under seemingly ideal clean rooms, accumulate inside your notebook especially on the fan blades reducing its capacity for cooling and in a worse case scenario seize your fan due to caked on dust on the fan blades. Avoid very dusty areas or places where, over the long term you know fuzz, fur, or even smoke can enter into your Macbook.
    Is it making a buzzing or scraping noise?
    If you only hear it in a quiet room, that is normal.
    noisy fan reasons:
    A: you notice it more in a quiet room (the typical case) which is normal, all is AOK
    B: fuzz and dust has caked onto the blades causing the fan hub to get off balance and make a buzzing sound.
    C: fan rotor is going bad and making a whirring or buzz noise (rare).
    D: Fan is spinning up due to excess heat from gaming, heavy graphics (typical, all is OK)
    A and D are normal
    B and C are not.
    Do you use it in a dusty area or where there is a lot of pet fuzz?   Laptop fans act like little vacuum cleaners and take in dust etc. from the ambient air around them.
    If B and C continue for a long time (B is just a cleaning), they eventually cause the fan to either seize and/or die.
    Contact Apple for a new fan assy.

  • Soundblaster Audigy SE first sound really loud, then rest are quiet

    no matter which system sound I set as the first one the system plays back after starting the computer, it's REALLY LOUD, then the rest of the sounds are quiet. How do I get ALL the system sounds to be the same volume?

  • Computer is unresponsive and fans are really loud.

    Last night I walked into my room to hear my G5's fans blaring loud. I tried to move my mouse and the entire screen was frozen. I didn't know what else to do but to hold the power button in to force shut it down. I let it sit for a few minutes and then powered it back up. It made it all the way to my desktop but would not load my icons and the fans started blaring again. So I forced it shutdown again. After powering it back up 2nd time it won't go pass the grey apple screen. The fans are blaring loud again.
    What is causing this and how can I correct it. I am able to get online via my Macbook Pro but I really need to get to the bottom of why desktop is acting crazy!!!
    Thanks!!!

    No.
    That is why I always advise,
    CLONE and run Disk Warrior on clone, then test that out.
    And in the past and for PowerPC, Applejack.
    If it is with cache files, those are of course temp files, and which SD doesn't copy, some of which now 10.6.x is better at clearing during a SAFE BOOT but for which people use to use AppleJack (and Maybe Leopard Cache Cleaner) and since we are talking PMG5 10.4/10.5 PPC.
    To check all the files, TechTool Pro 5.x or Drive Genius 3 (never used DG, never needed to).
    Have multiple backups.
    All of these system and disk repair and maintenance? mostly so you can mount and backup any files you need to, and then proceed to restore from good backups.
    Usually, people are lucky and they can continue to work. Disk Warrior used regularly and for preventative maintenance (rebuild but also scan files and folders).
    HFS+ is not reporting errors (they can be just weak sector, more retries on read) and even ECC is not perfect either at stopping memory errors.

  • 2010 Mac Pro fan gets really loud after 10.8.4 update

    Hey all,
    I've been having some issues with my fan since upgrading to 10.8.4, it's been incredibly loud compared to what it use to be. I typically run very graphic intensive programs and heavy video use but even simple tasks like browsing the apple site with nothing else running the fan slowly ramps up it a distracting volume. You can even hear it in the next room.
    I've reset the ram, done a clean instal, blasted out any possible dust, it's in a well ventilated area, even run system hardware tests Nd everything passes I really don't know what else to try? I've searched lots on the Internet and I can't seem to find a solution nor do some others. Some say it will be a fix in a later update? Is this a known issue that needs to be fixed? I miss the snow leopard days :(
    Everything was wonderful until 10.8.4...
    Any advice or tips would be greatly appreciated I love my macs but can't work with really noisy machines.
    Thanks y'all!
    Machine specs -
    10.8.4 Mac OSX
    2x 2.66 6 core intel Xeon
    20Gb 1066mhz DDR3
    Nvidia quadro 4000
    4 hard drives
    1 super drive
    Running dual monitors
    20" apple cinema and 23 LG

    I know there aren't 'as many' but it is better now than it use to and you don't need $2000 Quadro 5000 or something, a $600 GTX 680 or somethjng from EVGA will do
    Don't know what but MacRumors did a good job on one thread detailing possible GPU AMD FirePro possibilities. Yes it is huge change.
    People have always said that about PCs. I have a few. Not for gaming but that is the only way if you want like a small percentage of users, to spend on GTX 690 x 3 for $$$ (big bucks just for gaming).
    I can't recall a Mac Pro 5,1 2010 with 2.66GHz (sounds like a 2009) and 12-cores. 2,26 GHZ yes but that is just, does not make sense to give up MHz for more cores. The 12-core 3.34GHZ custom build, yes, but again that was never an Apple BTO choice either.
    Apple has always disappointed geekheads you might say.

  • Is it okay that my fan is really loud?

    it sounds like my fan is working extra hard/very loud.  I am online and have microsoft word open.  it is also being charged. 

    When you press Shift-Cmd-4 all together you'll see the mouse pointer turns into cross hairs with a small circle. At that point you can release all those keys. Next drag those cross hairs with the circle around  whatever it is you want to save as a screenshot. You'll see that area becomes highlighted in grey. Then when you're satisfied that you've captured the area you want, just release the mouse. Might take a few practice tries.
    Just for future information, you can do a full screenshot using Shift-Cmd-3. With that, no need to select anything. But don't do that this time. The resulting image will be too small.
    EDIT: I see you figured it out.

  • Fan making really loud noises

    Hi,
    The fan on my laptop is making very loud noises, like something's stuck in it, but after I took the entire laptop apart, and cleaned the dusty fan, the noise level is still the same (+3 extra screws now...=( ). Is there anything else I can do, or do I need to replace the fan? If yes, can I get a replacement fan at any normal computer store? The model is Compaq Presario V3233AU. 
    Thanks!  
    Message Edited by ArielSY on 10-26-2009 09:36 AM

    So I just talked to an HP online specialist, and it turns out that it might not be the fan at all, and might instead be the hard drive making the grinding noises. I cleaned the fan, and my laptop temp has gone down significantly, so I'm not sure that was the problem either. The specialist said that I could take the laptop apart, take out the hard drive, and run the laptop to see if the noises continue to confirm if the fan is making the noises. If not, the hard drive is probably replaceable =P 
    However, he ALSO told me that I could continue using my laptop, regardless of the noises, which was confusing, as I assumed that anything wrong with the hard drive probably had to be fixed immediately for me to avoid losing all my data? Help! What should I do?!  

  • 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!
