Fan makes really really really loud noise

it sounds like it has been pushed out of line, and is hitting something as it goes round.
any ideas?

Sounds like a bad fan bearing.Give AppleCare a call,it's covered by warranty.

Why dose my Macbook makes really loud noise ?

When it is loading a disc, doesn't matter it's has movie, music, or software in the disc, the computer always makes this loud noise, it's driving me crazy every time, is it normal ?

My Macbook's drive if pretty loud too but I don't often have a disc in there. Usually only for a software install (not very often) or to burn something (fairly often). The fan running, especially if you're watching a video stream is pretty common. If you're really concerned, do you have any friends with MacBooks or is there a store nearby that sells Macs? Go check them out and see if your's is really loud of if it's just the nature of the super drive to be that loud.
Like I said I think mine is pretty loud but I don't use it enough to let it bother me.

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!

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?!

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.)

It's fan sounds really loud...should i be worried?

so hot imac, that seems to be a common one.. but now it's fan sounds really loud...should i be worried? obviously it's cool the hot mac but it's very loud

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

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.

My fan makes a bit too much noise! Whats wrong?

Hello,
For a couple of months my computer has been making quite a bit of noise. I think that there is something wrong with the fan, but I'm not quite sure what to do. When I go on skype and talk with my friends, they say that they can even hear my computer's fan! Even through the telephone. If I try to load something, something that's Java, then it will only load if the fan is making a lot of noise. If my computer is silent then it won't load the program. Should I replace the fan in my mac or what should I do?

Sofie,
It sounds like you have bigger problems than the noise of your fan, as you mentioned in your post,
"If I try to load something, something that's Java, then it will only load if the fan is making a lot of noise. If my computer is silent then it won't load the program."
You mac should load java regardless of the state of the fan, I think you may have other issues with your mac as the status of your fan making a lot of noise or not should in no way affect your ability to run applications on your Mac. Have you tried running the Hardware test on the CD/DVD that came with your iMac ? that may help track down a possible problem. Failing that trying doing a new install of your mac (remember to back up all your files first). I know that sounds a bit drastic but its worth a try.

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!

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.

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.

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.

Ipod makes really irritating noise as scrolling through names of songs

Just bought a ipod 3gen as I think its prettier than the new one, and i have bought a JBL on stage 111 model speaker....rushed home to try it, but when it is attached it makes clicking noises all the time, and can be heard through the songs. Its when the titles are scrolling or it is counting though the time of the song.....its really annoying! Is this my Ipod doing this or my new speakers?

But that doesnt stop it. The clicker button says its off and its says it is playing though the speakers. But for some reason it is really bad when playing though the bottom adaptor thing rather than the aux out. any more ideas?

My macbook pro is overheating and the fan is really loud. How can I fix this?

My mackbook is overheating and really loud

Try an SMC reset.

If that does not solve the problem, what temperatures are you experiencing in your MBP and what applications are you using?
Ciao.

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.
