MacBook Air :: Fan Making Constant Buzzing Noise
Mar 16, 2008
I have had my MBA for almost a week, and I've had no issues so far. Until now. This is the case: The fan operates as it should. It stays on 2500 rpm at light use, and increases with heavier use. At 2500 rpm I was not able to hear it without putting my ear next to the keyboard. That was yesterday. Today the fan produces a new noise. It isn't very loud, but clearly audible at 2500 rpm in a quiet environment. It's a low, constant, buzzing kind of noise. It also increases with fan speed.

I purchased a 21" iMac a couple of months ago. Today it started making constant buzzing/humming noise. It's not really loud, but it is noticeable and annoying after a while. It stops if I put the computer in sleep mode or turn it off, but it starts back up the moment I turn it back on again. It sounds like it is coming from the bottom of the screen near the speakers. I have tried adjusting the brightness and volume, but to no avail. I also tried lifting the computer off the desk to see if it was just vibration, but that did not make a difference either.

I was just downstairs in my basement using my macbook and I decided to come upstairs and when I got up here I noticed that my fan is making a weird buzzing noise. I can tell it is my fan because when I make the fans spin faster in smcfancontrol the noise gets louder. Could this be something that is in the fan or could this be a more serious problem? I can take the back case off and check but I just wanted to know if this could be a serious problem with the fan. Is there any chance I could have bent something by carrying it wrong?

Yesterday I started up my MacBook Pro that I've only had for about 9 months. I immediately noticed that there was a barely audible buzzing / humming sound coming the inside of the laptop, most likely in the fans. I don't know how long this has been going on, and I really don't know the cause of it. So is this something I should be worried about (the sound is barely audible)? Or is this something that happens after prolonged use of the laptop?

I've had my Macbook Air 1.8GHz SSD since basically the day it was announced and aside from iChat video lag and YouTube (which has only happened lately), it's been almost perfect. One of the things I particularly loved about it was how silent it was, but as of Saturday, that suddenly changed. It now makings a constant (as in, never stops as long as the Air is on) noise which sounds like a harddrive being accessed; a kind of buzzing/whirring noise. It's not particularly loud, and once about 2ft away you can no longer hear it, but it is concerning that it would suddenly start.

My 20.5 inch 2.7GHz iMac is about a year old and has recently started making a low humming/buzzing noise from the top right corner, near the SuperDrive bay. The top of hte iMac feels quite warm when it makes the noise and usually stops if I hold my hand on top of the computer. Is this something I should be contacting AppleCare about?

I have an older 15" powerbook Titanium. About five years old now. Been working pretty well all five years, save for an external hinge I had to replace. Last night, the computer started buzzing from the insides, a buzzing reminiscent of a distant chainsaw. The program i was working in (firefox) just went to the pinwheel of doom and never recovered. I moved to the finder, which did the same. I forced booted. Same noise. Same problems. I can use programs for a few minutes, but then they pinwheel of doom and the computer freezes out.

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 purchased a Macbook Air from Amazon. The display is excellent but i've been having this constant buzzing noise going. It's very irritating and I'm not sure what is causing it. I definitely didnt hear this noise in my rev A Macbook Air or in Macbook air sin the Apple store.

My first generation unibody Macbook hasn't had any problems to this date but now it's constantly making that mechanical loading-like noise which is usually heard when the Macbook is switched on (the noise before the start up sound) or when the lid is opened to wake up the computer. Is there a fix to this?

Let me preface this by saying I am probably taking this to the Apple Store about an hour away from where I live tomorrow. For A while my MacBook Pro 13" has been making a loud spinning/grinding noise on occasion. Normally, I'd just shut down, boot up, and it would be fixed. Well, yesterday, that didn't work. After being told by the support guy that my free phone support expired 14 days ago (Mac bought in June), he said he'd do what he could to help. I told him about the noise and held the phone up to it (it is coming from the right of the trackpad). He said he had never heard that before and said to take it in to the Apple Store. I've found an Apple Support article, but it doesn't shed a lot of light on the situation.

Ever since the 10.5.7 update I've been getting issues with my macbook, this a new one. I've looked around google for any other similar incidents and there have been but none with a solution so I figured I would ask here. At random times my screen starts making noise, I say my screen because if I dim the brightness to zero it stops, and the brighter I get the higher the pitch, the lower brightness - lower pitch.

I just bought the macbook 13" (white casing) today and the first thing I noticed when I turned it on was the fan, it was extremely loud!! I let it run for awhile and it was still constantly loud. Then I tried rebooting twice and still the same problem. My room is only around mid 60F. Is there some function I'm supposed to turn off? Or did I get a lemon macbook?

After upgrading to Lion (10.7.3) it started this anoying beep sound that is almost unbearable. Also, I upgraded to Lion so that my Mac could run faster, but I am more disappointed now!

I received my nice new Mac Pro yesterday. 2.66GHz With one 160gb drive and one 500gb drive and some other customisations which, for the purpose of this are not relivent.
My first and most serious problem is a rhythmic clicking, which according to technical support is a known issue and is to do with my hard disk drive. The noise comes from the top front side of the machine and clicks at around 200bpm at all times. It is very audible and unnexceptable and for this reason Apple are replacing my machine.
The second problem which I believe to be more of a design flaw is noisy fans. I obviously know fans make noise but this is an intermitent buzz, at a constant frequency. It sounds like a bee is flying about in my machine and varies according to the angle of the machine and wheither the superdrive bay is open.
As you will understand I am very dissatisfied. My machine took 3 weeks to arrive and is riddled with problems.

The power socket at the back of the mac pro makes a kind of buzzing noise. Only for a short amount of time though. I have have never heard this before as it isnt that loud at all, and only cam across it by chance. I kind of figured out that it might be the electrical current.

I've owned my iMac for a little over a year and I started having a weird buzzing noise coming from a hard drive fan. Downloaded iStat, everything runs at idle speeds (hard drive fan at 1200rpm), so the speed is not an issue. Sounds like a mechanical problem. Also downloaded FanControl, and once I increase the fan's speed to 2500rpm, the buzzing noise goes away, but now I can hear the fan It kind of defeats the purpose of having the expensive computer, that used to be virtually silent. I am in remote location in Alaska, where we don't have Apple store and the only way to fix is to ship it to mainland. Apple warranty is over, but I still get additional 1 year of coverage from Amex credit card, but I would much rather prefer to to fix it myself. Any suggestions on possibly replacing the fan myself? I am really debating whether I should ship it to Apple and trying to go through American Express with warranty. That would be complicated and I would end up without a computer for a few weeks.

I've had my imac for under two years, and just recently I noticed it making an odd humming/buzzing sound at times. It's not the normal sound you hear when your hard drive is working hard, it's definitely different. It's not the speakers either, it happens whether they are on or muted.
My suspicion may be that it has something to do with the power. That's because I've been bug testing a mac beta game, and it often crashes my computer, and I have to manually turn off my computer by holding down the power button until it cuts the power.
Does anyone know why this may be and how I can prevent it/fix it?

I've been trying to audio record my piano playing with my unibody Macbook using Quicktime Pro 7. The recording is absolutely terrible--there is so much buzz, as if the microphone is being held right next to the back of the piano. In truth, I set my laptop about ten metres from the piano. The buzzing continues. It's as if the equalizer settings are set to max.

I have noticed this buzzing noise (like crackling electricity of sorts) coming from the left side of the machine out of the cooling vent. I bought my IMac in 2010 and have not had any problems with it until now. I noticed the "noise" a couple of months back and it would show up here and there every once in a while, it was not annoying, so I let it be. Until this last time, when the noise was loud and annoying, I could not just forget about it. I am under warranty and called into Apple to see what can be done for this problem.

I've got a RevB iMac G5 20" (1.5 GB ram) for a year and a half now, and since the last six months, the fans becomes quickly really loud for no apparent reason. It seems that my iMac think he is an helicopter and he want to take off by spinning it's fans the fastest it can. This is really annoying and it was not like that in the begining. It prevents me from doing audio conversations: the fan are so loud they make it impossible for the other to hear something else than my fans. Try convincing your friends to "switch to mac" with noise like that during an audio conversation! Sometimes just with firefox running I have my fans spinning really fast, with no intention of stopping anytime soon.

I've got a serious issue that needs to be solved, one way or another. I have a Seagate FreeAgent 1.5 TB External Hard Drive with two partitions on it: one for Time Machine, and one for extra storage. Yesterday, I tried to plug the drive in and nothing happened. It didn't light up; it wasn't recognized by my Mac. Just a strange buzzing noise that occurs every 2-3 seconds. So, I left it alone overnight. Woke up this morning, plugged it in, and same results.
I'm extremely upset and concerned over this. Losing this data is not an option, as there are more than just backups on this. It should be noted that the day before this started, it took a short tumble off my desk, and when trying to eject it yesterday, the drives would not eject so I had to pull it out. Please, if you know of any way to get it working again or to salvage the data on this thing, please help. I've attached an audio clip of what the drive sounds like when plugged in.

My MacBook Pro just started to making a clicking/ticking noise. I am assuming that it has something to do with the fan because when I shut my computer down, the noise stops, but once I start my computer back it, it starts once again.

My macbook pro was on while I was sleping and I think the power got disconnected and it shut off on its own. I woke up to it making this ping noise every 20 -30 seconds.
Here is a link to the YouTube video: [URL]
The computer works fine I've tried to turn it back on and off and it works ok.
