OS X :: Loud Whirring / Grinding Sound Coming
Jun 18, 2009
I just bought a new 24 inch 2.66 GHz iMac off of MacMall last week (6 days ago) and it has been working fine up until a day and a half ago. You see, I put the iMac to sleep for a while, and when I woke it up there was a moderately loud (but in no way ear bashing) grinding/whirring sound coming from the left area of the machine under the screen. I now noticed that the longer I have the machine on for, the louder and more annoying it gets. Does anyone know what is there (HDD, fan or what)? Also, is this something I have to worry about or is this an issue all iMac users face? I am new to OS 10.5 and modern Macs. I am really starting to get worried about this, as the machine is almost brand new.

My family just recently upgraded from an old PC to this 27" iMac, during the early part of the summer. While using it over the last little while, I would notice a noise that sounded like a harddrive spinning or possibly some sort of a fan noise. The best way to describe it would probably be as digital noise. It's not incredibly loud, but it's a decent volume, and can get quite annoying. It has a little bit of a squeak to it.
Over the last little while, it's become more constant. When the computer is in use, it'll usually occur quite often. It's quite annoying and obtrusive when I'm watching videos and I'd like to know what it could be.I think our computer is still under warranty, so I'm hoping to find out if it is something wrong, so I can get it replaced.
I've also been wondering if it's a fan, or a regular noise. However, it's so constant that I'm starting to wonder. The other night, I was watching a video and it seemed like it was coming on every 30 seconds for a long span of time. We don't run any memory heavy programs on this computer. If anything, we're just using Firefox, iTunes and/or Messenger. Sometimes Office. There's little to nothing stored on this computer, as it's brand new, so most of its memory is free.

I just bought my MacBook Pro last week. When I power it up, it makes a loud noise for about a second and a half. I think it's the hard drive starting up or the disc drive. I'm not sure which one, but it's pretty loud, so I was just wondering if anyone else noticed this and if it is normal.

I am new to the Mac platform but got rid of my pc because of the endless hassles. I have a two month old Imac that almost always finds an error when I try to burn files or music onto a dvd or cdr. Yesterday while attempting to burn music onto a cd the burner made a loud grinding sound.

first time i have ever come across. I have a Intel 2 MacBook Pro. There is no sound coming from the speakers even though it is not muted and the vol is turned to the max. There is sound coming if i plug headphones in the jack. Just noticed that there is a red light coming from where the headphone jack is...anyone have any idea how i can get my speakers to work again?

I have an external HD (old MacBook HD in enclosure), and I was using it on a PC earlier. The PC came up with a message in the bottom right saying something about a power surge to the HD, and that it couldn't be recognised. Since then, every time I plug the HD into a PC, it grinds and squeaks, and isn't recognised at all, yet when I plug it into my MacBook, everything works fine. What does this mean? Is my enclosure faulty? Or has it now got a Windows allergy?

I just had a question about my fan, whenever I'm on my computer for about 30 minutes plus, my fan starts making a kind of grinding sound, and my computer exceeds 200�F. I do play World of Warcraft, and I know this most likely causes the heating issue, but it only started about 2 months ago. And i bought my Mac mid-2009 and have had no problems until now.

I have the early 2008 Mac Pro, standard configuration. I run a 30" ACD and recently added a second monitor. Ever since then I have been hearing this faint whirring sound, as if something in the machine is starting/reving up and then whirring down. It's audible to me because I have my machine sitting on top of a pedestal desk right beside my table. Does running two monitors make something inside, maybe a fan, run wierd? Could it be the fan of the video card? I am just curious, as I had not heard the sound before when I was running just one monitor. Oh, and the second monitor in question is a Wacom Cintiq. Video card is the stock ATI Radeon HD 2600 XT. I dare not open the side panel when the machine is running to check what's causing it lest I mess something up. It's like, rrrrrrrrrrrrr, rrrrrrr, rrrrrrrrrrr, like a miniature reving sound. LOL, that's the best I can do to imitate the sound. It's as audible as the sound of the regular fans.

About 5 mins ago i rebooted my Mac, and in the boot process something started to buzz horibly. I was in a dark room, so it was very scary for me and very late too... Being scared i pushed CTRL+OPTION+SHIFT+POWER so it shut down imeaditly.
I powered it on, no buzzing. But OS X did not boot at all. Just stood there. Now I'm booting of the recovery DVDto disable my EFI pass, so i can boot verbose.

I just bought an iMac 24" 2.8Ghz Dual Core, 2Gb RAM, 320 HDD. This nice iMac has been with me only 2 days and the problems already started. I don't know why when I play a song either in iTunes or in web(audio streaming) the audio suddenly changes. It's as if you applied an EQ and removed all the low frecuencies and after a few seconds the sounds returned just as normal. When this "auto EQ" happens, the sound becomes "brighter" (I hope you understand what I am trying to say) but just as I said, after a few seconds, the sound is played normaly. I am running Mac OS X v 10.5.2.

On my 13" MacBook Pro, the hinge makes a cracking noise on the right side of the computer (near the power button) when the screen is positioned all the way back.
The entire hinge also makes a loud popping noise when I adjust the screen position. The screen seems very tight, and it takes a little bit of effort to move the screen, and when the screen is moved it makes the loud popping noise.
This is probably going to make some of you guys cringe, but sometimes putting pressure down on the top of the case close to where the black hinge meets to unibody enclosure seems to stop the popping noises. Putting downwards pressure on the hinge, or flipping the computer over and putting pressure on it that way, also seems to alter how much popping noise there is.
If I mess around a bit with applying pressure on different parts of the computer around the hinge, I can usually eliminate the noise. But, the cracking noise when I put the screen all the way back is still there.
It's not interfering with the operation of the computer, it's just incredibly annoying and this is only a four month old machine which shouldn't be creaking and cracking already.

Sometimes I lift and carefully move my 17-inch MBP a short distance to another flat surface without putting it to sleep mode, it starts making really loud mechanical noise when I put it down, so loud that people in the same room can hear the noise and I can feel vibrations too! What causes this? Where does this noise come from? Is my MBP defective?

My Blueberry G3's sound is entirely too loud, even on the lowest volume setting. Any way to get it quieter? I have to turn the sound down on each program, which is annoying, and any OS sounds are freaking overkill.

I didn't play any music. Not beep sound or something similar. The sound comes from one side of the speaker. I closed all application but the sound is still there. Sounds like fan or something blowing inside. I ain't sure. It stops only when I completely shut down my computer. When I switched it on, it's gone. My battery level is low (22%). Does this affect?

The last days appeared a problem on my IMac 21,5 inch Mid 2010, OSX 10.7.3. Without notice an intermittent sound appears very loud and the imac freezes. I have to re-initialize the machine. I've checked the console log and nothing.

I've read in several posts in this website's forum that there's a CPU noise problem with the MBPs, i even got to this site: o-noise-update...The thing is, that my computer is experimenting completely different symptoms, and that's quite annoying. I feel I'm alone in this The thing started like this, I sent my 13" Mid 2009's 2GHZ MBP to AppleCare to be repaired after the audio jack stopped working, they told me the audio card was to be replaced, and they did fix that problem, little did I not notice in the Apple Store (due to the store's natural noisy environment) that after this repair they gave me the computer back with the infamous hissing sound.

I noticed that when I move my MacBook Air when the fan is running, it makes a slight buzzing/grinding sound. Is this just air hitting the fan at a different angle or is it a bigger problem that needs to be fixed ASAP?

My Macbook Pro 15" [2 GHz Intel Core Duo, OS X 10.5.7, 1 GB 667 MHz DDR2 SDRAM] makes a loud crackling, chainsaw-like noise from the upper left part of the keyboard. I think it maybe the fan but I'm not sure. I've attached an audio clip of the noise:

When I click on the built-in mouse (whatever it's called), it's a lot louder/snappier sounding and feeling - makes more of a loud clicking sound - then my old Powerbook G4 did. Might I have got one that's a little out of whack or are they all that way? If it's normal, why so "clicky?" These days aren't they able to make things softer/quieter? I also noticed how sharp one of the corners is in the area where the latch (or lack of) is...that center area where you lift up the lid. I like that much better than the old one but does anyone else have the problem of a corner being too sharp?

few loud clicks when closing the lid of a MBP 13" slowly, mostly when its like in a 45 degree angle (the lid compared to the bottom)? Really creeps me out sometimes. Edit: sorry about duplicate thread, forum didnt seem to respond at first.
