Macbook has a very loud noise

When I turn on my Macbook Pro it has a very loud whirring noise. The noise continues for the whole time the macbook is turned on. Sometimes it becomes a little quieter but always is so loud my kids complain about it. The macbook is 5 years old but had a new graphics card/chip 2 years ago. The noise started about 2 weeks ago.
I took it to a genius at mac to check if the hard disc was failing and he couldnt diagnose any issue. Thought it might be the fans needed cleaning out.
Anyone got any ideas?
(I am constantly backing up in case the disc is about to fail)
Thanks

Yes, very likely, Ive seen endless clogged laptop and notebook fans ,......a lot of them were horrific
Dust and fuzz residue caked onto the internal fan
Dust bunnies and Fluffy’s fur
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.
Good news, if that happens, and out of warranty, fan is a very cheap fix.
Bad news, if you let the fan die and continue to run same, you can overheat your unit and cause unwanted damage.

HT1338 My macbook air got some loud noise

Just recently my macbook air got a loud noise when i plug in my cable. the fan sound is very loud and i just purchase my macbook recently,may i know what issue is that?

When you think about it, you'll have to agree that with this "description" we can't do much - other than advising you to "turn all sounds off"...
So, a better explanation of what type of noise and possibly in what situation it occured would be absolutely necessary.

this morning my PB G4 would not get to the password screen after power on. I have rebooted many times and very loud noises (like a HD spinning/rubbing) emits. Tried the Install disk and it cannot find the hard drive. Ran HW test and got a "Mass storage Error Code" message.
Did my HD just crash and unrecoverable? Time to replace my notebook?

I believe your hard drive has failed. Hope you have a backup.

Very loud noise heeelp

I bought my macbook pro on ebay 2 years ago and have not had any problems with it until recently. It gets very hot when using it and makes a very loud noise if i smack the bottom of it the noise stops but recently it hasnt stopped andis getting worse. any ideas?

I suggest not 'smacking' your MBP. The noise makers on a MBP are the fans and the HDD. You could open the unit and see if dust and debris have accumulated inside and if so, clean it out. Open Disk Utility>First Aid and run verify and repair. Also running the Apple Hardware test might give some clues:

If no problems are identified, than an appointment at the Apple store genius bar is in order.

My MacBook has become very very slow

My MacBook has become very slow for the last 2 weeks and often gets hangs with mail/address book applications. I have tried disc cleaning and permission repair but no change. Anybody has solution?

That confirms the hard disk requires replacement. There is nothing you can do about it until you return to school.
If you want to attempt a repair using your sister's Mac you need a FireWire cable with the proper connectors on each end. Connect the two computers, restart yours in Target Disk Mode by holding the T key as you start it, and run Disk Utility on your sister's Mac. The option to repair your hard disk will appear.
I don't believe the error you describe will be repairable.
If you have any information on the computer that you do not want to lose forever, copy those files from your computer to your sister's Mac. Since the disk is already damaged some or all of your data may already be lost.

Macbook Pro makes a very loud noise as soon as i turn it on

hi there im having an issue and i was wondering if someone could help me.. basically i only just bought my macbook pro about a week ago and my issue is that every time i turn it on it makes a really LOUD noise which is so irritating! and i know its not normal cause i have a friend with a macbook pro and his doesn't do that the noise he has is very low.. i was wondering if someone could help me out?

You might try running the extended version of the Apple Hardware Test (on one of your gray system discs) and see if you get anything in the nature of an error code which would point to the cause of the noise.
Also, download iStatPro and use it to check your fan speed. If it is 6000 RPM or so, that is likely the cause of the noise. Fans normally idle silently at 2000 RPM, so 6000 RPM would not be normal.
Also, if the noise is the fan, open Activity Monitor. Select "All Processes" at the top and "CPU" on the bottom. Look for a rogue process which is consuming an inordinate amount of the CPU.
If the fans are at 2000 RPM, there is a high possibility that the noise is coming from your hard drive. If so, back up everything immediately and contact Apple about a repair or replacement. Since your Mac is just a week old, you may be able to exchange it for a new one if there is a hardware problem with it.
Good luck!

Hi my late 2008 model Mac Book Pro has gotten really slow and has made a loud noise twice in the last month.

My Macbook is not acting right it has gotten very sluggish online and has made a really loud buzz or screaching sound twice in the last month. The first time I was just on the internet and it wouldn't quit making the loud noise until I turned it off and back on. This last time it made it while restarting it or was in the process of restarting from updating and while it was still a black screen it made that noise but stoped on its own this time. I have no idea what to check in Macs or where to looks for errors or problems. If someone could please direct me in what I can check to see if there is any info on what may be problemactic on my computer. Thank you. Laurie

Thank you ds store for replying. Not to sound ignorant but I am when it comes time to this...how do I upgrade to 10.6? I also think I have all the ram installed I can on it. This is what system profiler shows in memory.

Also the link you profided is this what the update to 10.6 will provide? I really didn't understand the tech language so I didn't understand what it was telling me. I am sorry to be so inept on this. I just had to have the battery replaced about a month ago and while in the store I was asking the tech to check all the error messages and make sure everything was OK because I had no clue what they meant or if I had any problems. I just use it I guess you would say. The tech said I didn't need to worry about any of that stuff that Mac's don't get viruses and I was fine. Well that didn't answer checking for hardware problems or anything like that but he didn't have anything else to say about it.

Macbook pro fan making loud noises and going really fast. Now the fan doesn't work at all and my computer gets extremely hot almost instantly. Is there a way to fix it without having to pay a ton of money to have someone fix it for me?

I've had my Macbook pro for about 3 1/2 years now. It has worked great until recently. A few months ago I noticed that the fan would always run really fast when I was doing simple tasks. After a few weeks/months, the fan was still really fast but it also started to make these loud noises. Now, it only occasionally makes the loud noise if I move my computer after its been stationary for a while. The fan no longer works at all and my computer gets exceptionally hot almost instantly when I turn it on. Is there a way to fix this problem without having to pay a ton of money to have someone fix it for me?

You can try a SMC reset:

My powerbook makes a very loud noise for hours!

i dropped my powerbook off my lofted bed the other day and it landed on the ground on the very left side. the charger is a little bent and split (the actual thing you insert into the computer), and the very left side where the charger whole is is a little bent.
however, there's been a noise coming out of my computer like a tktktktkttk noise constantly. it's very loud and disturbing. the powerbook runs fine except for this noise. i don't know if a fan is broken or something. the noise will stop when i put the powerbook to sleep and usually will stay quiet if i'm either running just safari or Word, but if i open itunes or ichat or anything where it needs to start something up the noise goes on for hours.
it started last night for a few minutes, then stopped, and now it's been doing this the entire day.
my questions are:
1. is this a problem with the fan?
2. is there anything i can do to stop it?
3. what is the problem?
4. how much will it cost to repair? i have applecare, but that runs out in feb., and i knwo they won't cover it for accidential damages.
5. any other advice?
6. has this happened to anyone before?

Hi ...
If the sound you hear on startup sounds like a "chord" being played, that's ok. That's telling you your Mac passed it's startup diagnostic tests. But a "whirring" noise.... no, that should not happen.
If it doesn't sound like a chord, probably best to take it back for a replacement. You have 14 days from the date you received the product for an exchange. Beyond that, your iMac has a one year limited warranty.

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.

160 GB iPod Classic: VERY loud noise upon connecting!!

Hello,
Every time I connect my iPod to my computer, it makes these very loud and frightening grinding noises. It has only happened since I got my iMac back from repairs, during which the hard drive was replaced.
It only occurs when I connect, and later, when I eject. After a while it stops.
Nothing appears to be wrong with the iPod, and it syncs fine. This noise is the only issue.
Here is a video showing what happens:
http://www.youtube.com/watch?v=YlhOIDZVOww
Note: you may need to turn your volume up to hear it.

Yeah- that sounds very frightening indeed. I also have the 160GB iPod Classic black but it purs like a kitten. I've had problems with the battery meter not being accurate but I can deal with that. I hope you have it insured with an extended warranty like I got when I bought it at Best Buy last year.

Retina MacBook Pro fan very loud and usb mouse disconnecting when restarting the computer

2 days ago, I got a brand new retina MacBook Pro 13 inch with the specs 2.8 GhZ i7, 8 gigs of ram and 512gb ssd. It should definitely be functioning properly since it's a really expensive computer, but I already noticed a few problems that I hope you can help me with.
So first of all, when I play World of Warcraft, the fan seems to go up to 6000rpm and is very loud. I checked the activity monitor and it says WoW is using about 60% CPU, so it shouldn't have to be that loud. I also installed smcfancontrol, but it doesn't seem to lower the speed of the fan.
I ran an apple diagnostics test and it couldn't find any problems, and I also tried resetting my smc, but the fan is still going very loud.
And the second problem I have is, that when I have my mouse usb connected to my Mac, and I restart it, it can't detect the mouse anymore. So I'd have to pull out the usb plug and put it back in everytime I turn on my computer. isn't it supposed to automatically connect to my mouse when it's already plugged in?

Matt,
Try reading this, then go to the section on Resetting the SMC for a Macbook Pro with a battery you should not remove.

My MacBook has become very slow to start up. What could be slowing it down?

My MacBook is now very slow to start up. What could be causing this and what is a way to repair?
Thanks, Chris

Hello Chris,
A variety of things could be causing the slow startup. The first place I would look is at the Login items on your MacBook to see if there are items in this list that are set to automatically start. Having applications automatically start will increase startup time. This article has the steps to do this:
Mac OS X 10.6: If items automatically open when you log in
http://support.apple.com/kb/PH6811
The steps from the article should work for Mac OS X 10.4-10.8; the only difference in Mac OS X 10.7 and 10.8 is that the Accounts icon is named Users & Groups:
To permanently prevent items from opening at login:
Choose Apple menu > System Preferences, and then click Accounts.
Click Login Items.
Select any items you don’t want to open automatically, and then click the "-" button.
If you are still experiencing a slow startup after that, you might want to try the steps in the following article:
Mac OS X: Gray screen appears during startup
http://support.apple.com/kb/TS2570
I hope this helps!
Best,
Sheila M.

SuperDrive vibrating and making very loud noise

Whenever I finish ripping a CD, the SuperDrive starts vibrating (excessively?) and making a loud noise for about 10-15 seconds... I was thinking that was normal, but recently the noise has kept getting louder and this last time the whole MBP was vibrating so much I ejected it before the noise stopped...
Would this call for a visit to the Genius Bar?

Yes, a few months ago I noticed it making a lot of noise for 10-15 seconds after CDs finished ripping to iTunes, though I can't say for sure it wasn't doing that before. Within the last few days it's gotten so bad that the whole desk that the MBP is sitting is vibrating heavily... not normal, I assume. :/
This would be under warranty, right? (13" refurb MBP bought in Jan 2010)
