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.
View 1 RepliesYesterday 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 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?

This is in reference to a Mac Pro 3,1 8-core purchased around Feb 2008.
Lately, I've noticed a strange noise coming from my power supply that sounds like the noise a refrigerator radiator makes. It's a humming noise that rapidly comes and goes, constantly.
The power supply fan speed was running at 599rpm yesterday, but is running at 629rpm today.
I'm not sure if the problem could've been caused by adding additional ram (12GB, OWC) or an additional HDD (3rd HDD, WD), but I didn't really notice the noise until after adding these components.
What could be the cause of this problem? What are my repair options if necessary (without Apple Care)?
I'm new to this forum and I just bought a new iMac 20" 2.66GHz, I turned on my computer and noticed a weird sound (buzzing or humming noise) not loud but loud enough to here I notice when I messed with the Brightness it went away is there something wrong with that or is that a known issue?
View 16 Replies View RelatedAfter 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.
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?
..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

so i love my new 27"; it's simply fantastic.... so far. i encountered a problem when i plugged in a 1/8 to RCA to go to my surround sound system. There is a loud humming sound coming from the speakers when i connect it. i tried to wiggle it and push it further to no avail. the sound was still there. i tried using another cable and the sound was still there. then i tried plugging in my headphones, and they WORK FINE! what the hell is going on and how do i fix this problem?
View 1 Replies View Related 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?

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.

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?
View 5 Replies View RelatedI have an early 2008 Mac Pro. For the past 6 months or so, it has been making a whirring, clicking, chirping noise. It does this constantly, no matter what I'm doing. I replaced the hard drive, but that didn't help. The sound appears to be coming from the rear of the computer, near the top. (where the power cord plugs in).

I was looking on GeekBench and noticed there are quite a few quad core iMac that are running faster than the 2.66GHz of the i5 and the 2.8GHz of the i7. I can't make sense if people really are trying to overclock or just somehow are making Geekbench think they have a faster CPU/are editing their scores somehow. How in the world could one overclock the iMac when cooling is a serious concern?

View 7 Replies View RelatedI 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?

My iMac 20" G5 (PPC, working with Tiger 10.4.11), bought in April 2006, has the following illness:
When I work locally, it functions fine. When I go into Internet, it starts purring and whining.
When I watch a video on YouTube, for example, the purring and whining increases and finally the screen blacks out. With a mouse click, the screen comes back but goes out again immediately.
After shutting down the system and giving it some rest, everything starts working again normally, but only until I go online.
I have tried to use Disk Utility, but the install disk that came with my Mac gets ejected.
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.

The computer works fine I've tried to turn it back on and off and it works ok.
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.

Seems like a click noise every 10-15 secs even when hard drive is idle
I have a friend with an ibook and it was working fine until one day all the sudden it started making a spinning noise and he restarted it then on startup it beeped.
