Intel Mac :: White 2006 Loud Humming Noise?
May 11, 2012
I have a 2006 White Intel Imac and I recently replaced the Superdrive with a non apple Panasonic Superdrive Model: UJ-85J-B from a used Acer Laptop. The replacement drive has no sensor circuit board. After putting it back together there was a loud humming noise and I assumed it was the new drive but when I took it out and started the Imac without it the noise remained? Now I am thinking it is the fan just below where the Superdrive sits? I blew out as much dust as I could from this fan and around the bottom of the case and that made the noise just a little less annoying. It sounds like it is about to take off like an jet airplane?Â

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.

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?

When I turn on my 17" iMac I hear a loud clicking noise. The noise repeats every few minutes and finally a folder icon appears with a question mark in it. Could my hard drive be failing?

I have a refubished iMac G5 OS X 10.6.8 desktop that was purchased in Aug, 2006. Recently it has been either freezing, shutting down completely, or the display will just shut off multiple times per day 20+ times/day. I am not interested in purchasing the $49 help from Apple. Is it time for a new computer?Â
I've been attempting some troubleshooting:
I have plenty of RAM- we installed more memory about 8 months ago. Temperature running at 40 degrees CÂ
I reset the SMU but now am hearing a loud fan sound and there is air blowing out of the horizontal vent in back of the desktop- which does not typically happen. The computer has not crashed since I reset the SMU 20 minutes ago. I'm worried about the noise.Â
Also, it has been really hot where I live, with a heat index of 110 today and I don't have air conditioning. Current indoor air temp is about 86 degrees F.  Â
Also, I have been seeing thin horizontal stripes across my screen for the past few months, related or unrelated issue?Â

My Mac Pro 8 Core 2 x 2.8 GHz Quad-Core Intel Xeon with Leopard 10.5.8 started making a humming noise about a month ago. The humming noise is very consistent in pitch and is always humming whenever the computer is on, except for when sleeping.

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?

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.Any ideas what to do? 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.

After returning 4 21.5" imacs with yellow screens and hard drive noise, I decided to try a 27" and finally a beautiful screen with no problems, no hard drive noise. I was very happy...untill I started hearing a humming noise that sounds like it is coming from the power supply. The noise stops when I put it in sleep mode. I tried a bunch of things to determine if it was the fans or hard drive and that was not it. I am pretty sure it is the PSU humming all the time. This is the first imac with a perfect screen and now it is humming. I am so frustrated.
What should I do? Have the power supply replaced or return it for another one and take the chance of getting one with a yellow screen? I am still within my 14 days of original purchase date.

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?Â

..by the power unit at the back of the machine - where the power cord goes in.
I happened to be switching out displays at the back of my MP today. Could hear the fan at the lower back portion of the machine (as normal). but this time could also hear a very slight electrical hum just by the power unit -- is this normal (the hum) does yours have this hum?
I never heard it before. guess my head was never that close to it when the MP was on the floor. but since i moved it to the top of the desk my head is closer to it when I switch out the DVI ports
Trying not to be obsessive. I'll run before the white coats turn up by the front door

There is a loud and really annoying humming & static noise when I connect my charger to my MBP. The humming only comes out of the headphones jack, and not the MBP speakers. This really cripples me in my work as I am a music producer.
Mp3 of the noise: [URL] ....

So my 20" 2.4 Imac crashed on me twice tonight. A box popped up telling me to hold down the restart button for several seconds to restat. The second time I did this it just sits with a white screen and give three loud beeps over and over. Is there a fix for this? Is it my ram? I'm at a loss.

I had the fans and HDD replaced in my 1.67Ghz PB G4 in January, but I think the fan noise is getting too loud again, plus the HDD randomly squeaks and squeals. The problem with the random squealing is that I can never start the camera on my phone quick enough to record it, and it is completely random! Does anyone know what the normal operating noise is for my laptop, or where I can find this out from? The normal fan noise is OK, but when the processor is under full load and the fans kick in to full speed, it sounds like the vacuum cleaner is on in the room. Should I take it back to the shop? It was 'repaired' roughly 2months ago.

I've noticed that most Macs have their fans run around 2000RPM, maybe 1300RPM. I was surprised to find that my CPU fan runs at only 500RPM pretty much all the time. However, it is much louder than those other Macs that have higher fan speeds.
Oh, and in case there is a misunderstanding, the fans are NOT running fast, and the temps are low. I've seen a few people complaining about this only to have answers about reducing the fan speed.

I have a 15" MBP from around 2006, the one where they first introduced the new magsafe connecters.It's started to make a rattling noise which is very rythmic leading me to believe its the fans. Several years ago it started to make a clicking noise but that stopped and until recently it's been fine.
If it is the bearings on the fans or something like that, how much would that cost to fix?The machine is well out of warranty now.

My G5 has been making more noise at start up. It sounds like one of the fans is making a grinding "rrrrrrhhhh" noise. My living space if very cold and quite dusty (warehouse). I notice it more on colder mornings ( inside temp 45° - 65°F ). Should I refrain from using my machine on cold mornings/nights until the heat is running?

I have a mac book pro, version 10.7.3. When I use quicktime player 10.1 to do a screen recording, and I turn the volume up, there is a loud screeching noise. The noise goes away if I turn down my laptop's volume or if I turn down the volume in the quick time player settings, but then my video no longer has audible audio.

I have a problem with my G5 freezing and it is preceded with by loud fan noise. I was wondering if the hard drive could be the problem? It had the problem with 10.4 as well as 10.5. It happens at startup most of the time and eventually lets me get up and running and stops being a problem.

For those of you that have the new imac, is your HD also pretty loud? I notice it constantly. Whenever I am browsing I can hear the ticking noise for a couple of seconds, this restarts every time I navigate to another page or simply by typing text like I'm doing now or scrolling down. I realize this is with all HDs, but this one is pretty darn loud. Does anyone else have the same issue?

I have a MacBook Pro 2009 with a 500GB drive (WDigital, I replaced the 160GB). I was using Perian to play mkv movies, and yesterday I downloaded Plex to try it out. But in both every time I play a Mkv file the fans start spinning, I think it's the fans or maybe the hard drive. But it's quite a loud whoosh all throughout the movie. Is this normal or playing a mkv file shouldn't make any noise at all? Should it use a lot of CPU? I'm using Leopard latest version.

Anyways, at the moment my mac is around 6 months old and just recently I am noticing that the fan is starting to vibrate- like when I type on the mac with my palms rested on the computer I can feel the vibrations. Now it is subtle but was not there before. As I am typing this the fan is at 2000 rpm. Also, when I am not out with the computer. I hook it up to my 23 inch monitor and a portable keyboard. Now when I do this I can hear a very loud noise coming form the computer while using it as a desktop. Almost as it its straining to use it. Its not so much a violent noise as it is that the fan seems to be over working.
I dont know if I am getting paranoid or if this is a serious problem- I have a 3 year warranty from bestbuy. The small vibrations I can feel form the computer seem to be like a small issue- however my friend beside me with the same model- her mac is silent and doesn't vibrate subtly. However, I am more worried about the louder noise it makes when I hook it up at work. Like when i put the computer to sleep I can tell a substantial noise different in terms of it going silent after I put it to sleep.

For lucky 15" i5/i7 owners: how silent are they? Does the fan come on at all? If so, after how much load? Any other noises? Hard drive?

I've just purchased a new Macbook. I'm very happy with it aside from the fan noise, which seems a little loud to me. Now, before I bring it into the Apple Store to have it looked at I just want to check and see if maybe I'm just being overly picky. I downloaded iStat, based on some Google searching I did on the subject and my fans are running around 2000 rpm, which I understand is normal. But in my apartment, which is admittedly quiet, I can hear my fan running constantly. It isn't extremely loud, but it isn't totally quiet either. I'm just wondering what level of noise I should reasonably expect out of my Macbook.

My Macbook Air has suddenly decided not to turn. I have tried the rebook using the left hand side keys 'shift/control/option & power' but still nothing happens. Every now and again when I try turning it on using the power button the fan turns on and is really loud?
