HELP! Really Loud Humming Noise. HELP!

PLEASE Help. All Day Today, My PB Has Been Making A Really Loud Humming Noise, Start Up Is Very Slow And Apps Keep Crashing. PLEASE Help Me.
Any Ideas On What It Could Be?
ThankYou.

There is a very high probability that it is your hard drive. If you can, back up IMMEDIATELY.
The same thing happened to me. Good luck.

Why does my MacBook Pro suddenly turn really really slow and make a really loud fan noise?

Whenever I turn on my MacBook is runs perfectly fine for 2 minutes but then it turns really slow (to the point that it takes ages to move the mouse cursor and to type) and make a really loud fan noise. What should I do to fix this?

Welcome to Apple Support Communities
There's a process that is taking up the RAM and CPU. Open Activity Monitor (in /Applications/Utilities), and select "All Processes" above "Show" in the toolbar. Then, order processes by CPU, and tell me which processes you see that are consuming more CPU

Loud Humming Noise?

Hi There,
Am using a new iMAC G5 and have been noticing after being on it after a short while it starts to hum - really loudly - when surfing the net mostly? Sounds like a loud fan. Anyone else have/know of this problem. Am new to iMAC and MAC and I love the machine but have been reading posts and there seems to be quite a few issues? Serious MAC users - what do you think of it?
Thanks....

Be that as it may, you must agree that the "noise" issue has been beaten to death in these forums, and if one does a simple search of these discussions they will find at least a dozen things to try BEFORE they start complaining here.
I personally have no problem helping out someone that has a "noisy" Mac, provided that person is willing to try the suggestions AND not use these boards to reiterate the obvious.
In the Mini Mac forum, one guy (I can too, but not until I read about his woes and started training my ear towards power brick sounds) can hear the pitch change in the frequency of his mini's power brick when the computer is sleeping and pulsing the light. As the light changes brightness, the brick changes frequency. Go figure.
We both find the noise annoying. Neither of us intend to file a lawsuit at this time.
Noise level, and for that matter image quality, are very subjective matters. I would really like to see the folks that are complaining about noise spend 40 bucks at Radio Shack and get a sound pressure meter, do a sound test, and then come forward with the results. My gut tells me that almost all of these "noisy" machines fall well under Apple's published specifications.
Ranting done.
Peace.

Final Cut Express REALLY loud beeping noise?

i've been using Final Cut Express for a few months now,
i have just started to edit a new video and i was listening back the music to see if it was mixed right, then a REALLY LOUD beep started. my macbook was on volume 2 out of 16 and it sounded as tho i had my laptop of full! or louder :/
what is this?
the first time i played the music, it didn't happen, but the second time it did? - it also did the same thing the other day!
-it isn't because i haven't rendered my music, because all my music and video is rendered. the noise is 100% louder than the 'unrendered' beeping

Beeping is usually an artifact of using iMovie video in FCE.
What exactly are your sequence settings & clip properties? (Frame size, vid rate & compressor).
And are you really using Final Cut Express on a Lion (10.7.3) machine?

G4 MDD has REALLY LOUD FAN noise!

Hello All!
I've just purchased a dual 1.25 GHz MDD G4. It has a much louder fan than the Graphite G4 (Digital Audio) that I have been using. Is there anything that I can do about this? Is this a known issue... or maybe is it just this particular machine?
Thanks,
Mark

Just Wondering...
Are loud fans normal for these machines?
Yes. They were nicknamed "The wind-tunnel". The noise was so bad on the early models that Apple offered a free replacement power supply with a quieter fan (and a slightly lower power rating).

Loud humming and super lag on pbg4(15i)

So this morning I woke to my powerbook humming very loudly. it may or may not have been the fan, but if it was, then it was working double overtime. Nothing I did made it stop, until I shut it down. While it was making this noise, everything ran very slowly, even such simple tasks as viewing my dock. Once I shut it down, Let it sit a few minutes and restarted, the noise stopped, but started again within a few minutes.
it seems that the longer that I let it sit, shut down and plugged in to a/c power, the longer it lasts after I restart without making the godawful humming sound.
Any ideas what this might be related to? I would just bring it right to Apple, but I am a little strapped for cash. Could it be something simple like a dying battery or something shaken loose that I could reconnect?
please help.

Whilst a RAM issue will cause problems running your PowerBook, I don't believe it will cause the loud humming noises you have been hearing. Therefore I don't think your problems are primarily with RAM - but it doesn't necessarily mean you have fully functioning RAM. Still worth a quick check, but I think your problems are elsewhere.
Can you elaborate on where the noises seem to be coming from? Are they at the front, to the left of the trackpad? Or are they in the corner/s towards the back (ie. nearer to the screen), where the fans are situated?
If the noises come from the front then I think you are experiencing the symptoms of impending hard drive failure (which is potentially one of the cheaper hardware problems to fix). The 'classic' symptoms of a failing hard drive are unusual noises, slow/sluggish performance, problems accessing files/applications, startup problems, lots of spinning 'beachball' activity and the problems may come and go (ie. it may work normally before experiencing problems and then work normally again etc).
If the problem is, indeed, impending drive failure then I would advise you to backup whatever data you can (unless you already have a backup) - whilst you still can. Otherwise the only other option is to replace the drive.

In anyone experiencing loud fan noise for late 2012 27in iMac

I am getting a rattle sould like fan blades (as opposed to the whoosh of air) on my lat 2012 iMac. Is anyone else having this issue. It can be quite distracting. Could it be a hard drive issue instead?

I have AppleCare cover so I will try to see if they do onsite repair as my nearest store is only about 2 km away. As I was using the computer last night I heard three incidinces of really loud 'static' noise as well!?! It went away each time but I managed to record the noise one of the times. I have included the 'rattle' fan noise also in the links below:

Loud hum when Imac sleeps

i've been using my imac g5 for a few months with no issues what-so-ever. just recently i've run into one major issue. when the computer puts itself to sleep...i get a loud humming noise that will not stop (i think its the fan running. the power button is disabled and i have to unplug the computer and plug it back in to restart it. any idea what the problem is? i think i may have changed the power saver settings just before this issue surfaced, but i'm not sure what would cause this to happen.

What it's doing is going into sleep mode and this is normal. You should be able to wake it up just moving the mouse or pressing any keys on the keyboard. What I want to find out is whether it's hanging up when it goes to sleep or if it will wake up normally as it should regardless of the humming sound. To check the Energy Saver settings go into System Preferences/Energy Saver.

Loud crunching noise

Hey just wondering my macbook makes this really loud crunching noise when i put a disk in it...it sounds like its eating it...the drive works absolutly fine its just an awful noise and i was wondering if it normal for macbooks?
thanks

The slot-loading drives in Apple's notebooks are noticeably noisier than similar drives in other devices, such as CD players. I have both an iBook and a MacBook, and the MacBook's drive is a bit noisier than the iBook's.
I would bring the computer in and have a Genius listen to the noise and see what he/she thinks. The sound may be perfectly normal.

Added Ram to Mac Mini & Now There is Loud Fan Noise

Hi everyone,
Today I bought a Mac Mini Core Solo. I brought it home and opened it to add an additional 1gig of ram. I now have 1 stick with 1GIG and 1 stick with 256mb of ram inside of it. After adding the additional ram I closed the case and turned the power on. It picked up the new ram but it is now making a really loud fan noise. I'm nervous that something has gone awry. Any suggestions for as to what is wrong? Did i do a big bad?
I'd appreciate any advice!

Sounds like a connector to the fan was pulled loose when you dismantaled the mini to get at the memory slots.
See the pictures here...

Open her up and check that the wires from the fan a re seated onto the motherboard correctly.

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.

Help with a super loud fan noise?

I bought this macbook pro from a friend late summer of last year and I belive it is a 2009 macbook pro. It has been working perfectly since I got it from him and I have had it in a case and had keyboard cover on it at all times. Since about a week ago, it has been making this really loud noise, which I am assuming is the fan. It sounds like a light drill and vibates the whole laptop. Using iStatPro, it shows that the RPM is rougly 2000 and the temps are at 50 degrees at their highest. Any clues as to what is wrong and if there is anything that I can do to fix it?

What is causing the very Loud Fan noise everytime I use the computer? What is causing the Heat as well? Please help

Please Help!
My computer has been making very LOUD fan noises. I know this cant be normal. How can I fix this issue?
This has been going on for a while now. As soon as I turn on the computer....the noise starts.

Go check out Activity Monitor on your Mac. It will show you which programs are running, and how heavy their use of your CPU is.
When mine does this, for some reason, I have a bunch of "Managed Clients" running at once. I use Act. Mon. to shut them down, and my Mac runs normally.
