IMac :: 24' Hard Drive Fan Buzzing Noise?

May 25, 2010

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.

Late 2008 iMac 24'. 3.06 GHz, 2GB RAM, 500GB Hard Drive, NVidia GeForce 8800GS.

Mac Pro :: Mac Pro Buzzing Fan And Hard Drive Noise?

Sep 1, 2006

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.

OS X :: External Hard Drive Makes Buzzing Noise/ Not Reconized By Mac?

Mar 8, 2010

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.

IMac :: Hard Drive Noise On My 27-inch?

Aug 20, 2010

I bought an iMac in 2009 from the Apple Store (core 2 duo). Ever since the first time I turned it on, I have been hearing a rattling noise from what seems to be the hard drive. It is a constant rattling sound, and you can really hear it when you click something or open something. It is only noticeable when the room is dead silent - when the air conditioner is on, I can't hear it.

Is this normal? Should I have it replaced/looked at? Should I upgrade to a Solid State Drive for a quieter experience? The model of my hard drive is: ST31000528ASQ

IMac :: Excessive Hard Drive Noise Even With No Activity

Nov 16, 2009

I am getting HD noise like every 20 seconds. Even with no activity. Per the suggestions of another user, I typed this in terminal: iostat -w 1 disk0
And the sound seems to coincide with the output whenever the first column has a value other than 0. So it seems there is activity, it's just not user initiated. Is this some kind of energy saving feature that apple is doing or is it a logging application? Is anyone else having the same issues? Even if you're not, could you run the program and check for 1 or 2 minutes (without any other apps open or doing anything) to see if you also get a value other than 0 in the first column every so often and an associated sound?

IMac :: Hard Drive Noise Caused By Partitioning?

Aug 14, 2010

My drives for all 3 imacs i have gone through so far were dead silent until I Partitioned them, then they made the classic stomach growl noises. I was just wondering if others with the noise problem had a partition or not, ause it seems making a partition should not effect the noise. Say I am crazy cause to me it sounds crazy but I swear the first two imacs were fine till I partitioned them. I am now afraid to partition this new one I have cause its quiet and I do not want to go back to the store again! Anyway others who have had this issue did you have a partition?

MacBook Pro :: Fan Noise Or Hard Drive Noise?

Oct 25, 2008

I just got my macbook pro yesterday and ran it all yesterday not hearing anything. Today when I woke it from sleep I could clearly hear the fan or hard drive going. I was in a quiet room and it's quite annoying.

istat says its at 2000 rpm so thats when I started thinking it may be the hard disk. It does pulse every now and then but thats even while it's just sitting idle.

I guess I could live with it but its just annoying. Anyone else having this?

MacBook :: Fan Making Buzzing Noise

Jul 22, 2009

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?

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.

Mac Pro :: Slight Buzzing Noise Around Power Socket

Nov 2, 2008

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.

MacBook Pro :: Making Humming/buzzing Noise?

Apr 4, 2012

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?

MacBook Pro, Mac OS X (10.7)

Laptops :: MacBook Pro Grinding/buzzing Noise - How To Avoid It

Oct 5, 2009

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.

MacBook Air :: Constantly Making Buzzing / Whirring Noise

May 12, 2008

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.

Applications :: Recording With QuickTime - Continuous Buzzing Noise?

May 16, 2009

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.

MacBook :: Screen Brightness Related Buzzing Noise

Jun 1, 2009

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.

Intel Mac :: Making Constant Buzzing/humming Noise?

May 6, 2012

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.

Intel Mac :: Buzzing Noise Coming Out Of Cooling Vent

May 23, 2012

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.

Jun 7, 2012

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?

PowerPC :: 15" Powerbook Suddenly Making Loud Buzzing Noise And Crashing?

Feb 28, 2008

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.

PowerPC :: Hard Drive Spins And Super Drive Make Noise - No Boot Up

Jan 7, 2010

My friend gave me his old Apple cube G4 + 15" Cinema display in like 1000 pieces. Its completely teared apart. I tried a lot, but it doesn't work. The original IDE cable wasn't included, so I bought one for 2 cents. It should work or not? Maybe the powersupply. I'm not sure. I don't believe actually that the hardware itself, like the motherboard is broken. When everything is into place and I connect the cube to the powersupply it boots immediately. I don't have to do anything. Harddrive spins and the superdrive makes some noise as well. This repeats itself every 5 seconds. The screen is connected and gets power through DVI, but no display. Both the cube and display have touch enabled buttons to switch it on, but they do not respond (I guess).. Motherboard gives 2 light. DS1 is green, DS2 is red.

Mac Pro :: SATA Hard Drive Noise?

Nov 3, 2007

I just bought a 500gig WD Caviar SATA hard drive for my Mac Pro. When it is being written to it creates noise in my speakers. I've had this problem with external hard drives before (Seagate) and thought I'd be avoiding this by going with an internal drive.

Could I have installed it incorrectly? Is there anything I can do, or should return it and see if I have better luck with a new one?

MacBook Pro :: Clicking Noise In My Hard Drive?

Aug 30, 2010

I just bought a brand new MacBook Pro about 2 weeks ago. I'd say about a week ago I notice a clicking noise when I pick up the macbook or move it at all coming from the hard drive.

I finally took to the internet to find out what was going on, and got mixed results. Some said that it was normal for a Macbook Pro and that it was securing the hard drive so it didn't break while I moved it, and a vast majority said that the hard drive's failure was imminent. So what is it?

I bought a 13" macbook pro only weeks ago and since the day I bought it I noticed any sudden movement causes a "clicking" noise from the hard drive.
