Sounds like a plane taking off!

The iMac makes a loud noise similar to that of an airplane takeoff – at first I thought that it was mostly related to web usage, but the more troubleshooting that I do, the more I realize that applications seem irrelevant.
I took it to the Apple Store and, although they replaced my power supply, the noise issue has not been addressed. I plugged it into different power supplies and electrical outlets but that does not make a difference.
I assume that the noise is being generated by a fan but that’s just a guess because I do not know a great deal about the inner workings of the iMac hardware. Could it be the processor? The fan? Or some other component?
I have had this issue since purchasing the iMac fifteen months ago but I just assumed that it was “normal”.
Has anyone heard of this?

Sorry to hear about your woes.The only time you shoud really hear the fans is if: a) The ambient temperature is high and, b) The computer is being stressed (Photoshop, video editing etc.)
My advice: call Apple and explain the problem. But before you call, note down your serial number (it's on the bottom of the stand), memory, OS X version, and detail the problem. You could also run the extended hardware test from the installation disc. To do this, start your computer normally and insert OSX disc 1 (mine came with 2 DVDs) when you get to the desktop. Restart, and hold the 'option' button on the keyboard. When the computer is ready, select the hardware test (surprise!). Select the extended test... and wait... and wait. It takes about 1 hour and 45 minutes on my computer. By the way, it's normal for the fans to howl when the test is in progress, so don't worry about that. If there are any messages, note them too. Then call Apple.
Good luck!

MBP frequently slows down and sounds like an aircraft taking off

I have the original MBP with the following: OS X 10.5.6, Processor: 2.16Ghz Intel Core Duo, Memory: 2GB 667 Mhz DDR2 SDRAM, 120GB HD
I've recently started to notice that while running 2-3 applications my MBP's drive will frequently (happens about 4-5 times a day) start sounding like an aircraft taking off and some of the system resources jump up to around 100%.
What can I do to remedy this situation?

Take it to your nearest Apple Store so they can hear it for themselves. Or if you have AppleCare or your computer is still under warranty, call Apple. If you computer really is that loud, then the Apple techs should have no problem hearing your computer +taking off+ over the phone.
Let Apple deal w/it.

G4 Hangs, Sounds like an Airplane Taking Off

My G4 has been running smoothly on Leopard so far. Lately, though, it has started hanging often... no spinning wheel, no opportunity to force quit... it literally freezes. I hold down the power button to turn it off and then on reboot the fan goes crazy... sounds like an airplane taking off.
I have fixed disk permissions. Reset PMU. Run fsck -fy. And it's still doing it.
I am also running several usb devices through a belkin hub: iPod shuffle, external maxtor 80Gig for time machine, and occasionally a canon powershot camera.
Last time I tried to import photos off the camera it had all kinds of trouble. Had to reboot several times.
I realize this thing is getting old... but my whole life is on it and I can't really replace right now. Any ideas?
Thanks!
Josh

If this is a Mirrored Drive Doors model, the fans are likely working as designed.
There are circuits inside that run the internal fans on their highest setting by default. When the computer is running properly, the software periodically checks the CPU temperature, and sets the fan to an appropriate setting -- almost always less than maximum.
At initial power up, and when the fan hardware is ignored (not turned down) for some large part of a minute, the fan circuits revert to the default, maximum setting to keep the CPU from getting so hot it is damaged. Sure is loud, isn't it!
If you are running 10.4 or later, boot it up (if you can) and check About this Mac > More Info > Diagnostics -- to see if is detecting any failures at startup.

Computer sounds like it is taking off

This may be a simple fix, but for some time my computer makes an incredibly loud background noise .. almost sounds like it is taking off. A very, very loud humming. I have run diagnostics on it and reinstalled applications, but to no avail. This may be a hardware problem, but I am unable to run the Apple Hardware test that came with the start-up software. Any suggestions?

This would get better response and a more accurate answer if posted in the G5 usage forum.

IMac G5 Sounds like a jet taking off

Our iMac G5 sounds like a jet taking off shortly after we boot it up and try to open any applications. Also, when we try to power down and then turn it back on, a flashing folder shows up with a question mark and finder icon. Any ideas out there?

If you have not already, reset PRAM

and if that does not help, reset SMU (power management)
http://support.apple.com/kb/HT1767
FYI - For some reason, you are posting in the category for the older iMac G3 (CRT display).

My G5 is not booting up and it sounds like an airplane taking off. I replaced the 3.6v battery, but did not correct the problem. Any suggestions?

Resetting the Logic Board
Resetting the logic board can resolve many system problems. Whenever you have a
unit that fails to power up, you should follow this procedure
before replacing any modules.
1 Unplug the computer.
2 Press the Power On button on the front of the unit.
3 Open the side access panel.
4 Remove the battery from the logic board.
5 Wait at least 10 minutes before replacing the battery.
6 Make sure the battery is installed in the correct +/-
direction.
7 Reassemble the computer and test the unit.

After installation it sounds like a 747 taking off.

Hello,
After I installed Leopard on a dual partitioned hard drive (the other partition has 10.4.9 and FCStudio 1)and Final Cut Studio 2, I then rebooted the computer. It never booted up, but it did sound like a 747 taking off. Only after a few minutes did I have to force a shutdown to end this noise and power. What is going on here and what am I missing? Does it have to do with installing Leopard on a partitioned drive or installing Final Cut Studio 2 on the Leopard side of the partitioned drive? Your help would be appreciated.
Thanks,
Jordan

I have a dual G5 and that sound you hear always happens when the computer first starts up but quickly stops as soon as an OS is booted, I believe it is all the fans running full tilt. However, in your case, something happened and your system cannot find an OS and therefore that loud roar continues for a long time.
The noise is normal - the fact that it keeps going is not normal but related to a failed install or at least the inability of your system to boot into an OS.
Start it up and hold down the Option key and you should get a screen with all the bootable partitions showing. You should at least see your Tiger OS.
You may have to reinstall or repair the Leopard partition but the Tiger should still be working.

27in iMac very loud fan noise. 3hrs after setup and running the fan came on. Sounded like a jet taking off.

Brand new fathers day gift. The unit is cool to the touch. Air being blown out of bottom is cool. Shut down unit was what I found to get it to shut off. That worked. I get up this morning and wake computer from sleeping and immediately fan comes on. I'm thinking I should take it back. 2 days old but the amount of updating it needed to do it was prolly built months ago.

Tammy,
You can do a SMC reset. BTW the port on the bottom is the air intake, the exhaust is on the back on the upper left. However I'd recommend immediately contacting Apple Care. The machine should be OK right out of the box. You can find the contact information in your country at AppleCare Contact Info.
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.

"Sounds" like someone is taking a snapshot of g5 without my permission

Hi There,
I'm concerned I'm being hacked because from time to time I hear the sound of a camera lens shutter.
Is there a way of detecting if there has been activity?
Any advice or help will be much appreciated.
Kindest regards
Rob Slaney

Sorry, Console is in Applications>Utilities, run that and watch the System & Console Logs around the time of the click.
But if you don't have an iSight or Camera hooked up, then the Sound is likely a Hard drive going bad, or a Fan, or...
If you wish to check further on the Hacking possibility, (doesn't sound like it to me, but), might look into this...

Thinkpad Yoga - fan sounds like a plane

In tablet mode (and mostly when the tablet is horizontal) then the fan (I suppose it is the fan) makes some horrible noise. I can't work with it at work in this mode as my colleagues look at me weirdly. When I lift up the screen a bit, then the fan stops in a struggling sound.
I did a video of the issue:
https://www.youtube.com/watch?v=e0Y0hEr3qKc
It's a shame because in latpop mode it doesn't make any sound, even thought the work I do in laptop mode is much more intensive. Would not be for the sound, this is the best laptop I ever had. The keyboard is great, the edges are not sharp, the screen is beautiful, the wacom pen works perfectly. An awesome computer.
Anyone one had this fan noise issue?

Hi,
Welcome to Lenovo Community Forums!
I’m sorry to hear that fan in your Lenovo ThinkPad Yoga is making noise.
If your laptop feels hot and shows any of the problems below, chances are its overheating or getting there:
Fan constantly running and making loud whirring noises
Computer struggling to perform basic tasks like opening a new browser window
Mysterious error messages popping up in random programs
Lines on your laptop screen (a sign your video card is overheating)
System freezing or the dreaded BSOD (blue screen of death)
The laptop abruptly shuts down on its own
First of all, update BIOS to the latest version.
Use dust remover spray to clean out of the laptop's vents. Dust can accumulate in and block the laptop's fan vents. Start using compatible cooling pads which will help in the flow of cool air into the underside vents of the laptop. Keep your working environment or computer room as comfortably cool as possible. Check if the fan is touching some wires during spinning to cause the noise.
Best Regards,
Mithun.

Sounds like 747 taking off after installation, no screen with which to work

Never, never never never never never partition any drive where you will be doing/installing, editing etc. any video production.
If you want use Tiger and Leopard, then either install one or the other on a separate, not partitioned drive.
Any do not ever partition any drive where you will be doing/installing, editing etc. any video production.
I guess I said that.
Jordan, video production should be installed and should run a cleanest system possible.
partitioning is not part of that system
in my view

Fans Like Jet Plane!

Has anyone else's fans just flared up as they were using the macbook on their lap, and become like a jet taking off?

Check your internal temps with Hardware Monitor of CoreDuo Temp. Also, run your Apple hardware tester once.

21.5" iMac sounds like a Boeing 747 taking off...

Sooo....I have a 21.5" iMac that has been giving me fits for the past couple of months. If I leave it on for more than a day or so, that baby really starts humming and, like the subject line says, sounds like a Boeing 747 taking off. It won't stop unless I shut it down then turn it back on. I ran that istat pro widget and discovered that when operating normally, the hard drives spins at roughly 1700-1900 RPMs. When it starts making that sound, however, it jacks up all the way to 5300-5500 RPMs! Sounds like the hard drive, right? Took to the Apple Store, explained what happened, and they recreated the issues. Sooooo, they changed the hard drive out for me. All was fine until last night when it did it AGAIN! Does anyone have ANY idea what it could be??

Hi, well I would sat it's another trip to the Apple Store, maybe they misdiagnosed! maybe the exchange HD is bad!
Apple warranty their work....L

Shutter sound that camera makes when taking a picture sound like it's dying.

The shutter sound that my iphone 5s makes when I take a picture sounds like it's dying. Anyone else have this happen on their phone? This hasn't caused a problem with taking pictures but it sounds weird.

Unfortunately, your naivete about complex electronic devices has misled you into a common misconception that Problem A = Cause B = Painless, no-effort, Solution C. It's all magic to you.
Virtually any problem can have a multitude of causes, if for no other reason that you have incompletely described the total state of the phone. More broadly, your camera problem is being caused either by corrupted code and or settings, of unknown origin, or a hardware issue. There is no way anyone determine psychicly. The only way to find out is the standard troubleshooting steps developted by Apple, and described In the User Guide.
it's taking more than half a day to put a big bandage on the wound and hope it fixes it.
Nonsense. 1-2 hours tops for 2 restores.
This has been a problem with the phone since the day I bought it. It can occur everyimte I use the camera app for a week then not happen as much for a couple months. In the past year, I have restarted, reset restored, etc several times and I still have this problem
You oddly failed to mention any of that in your initial post, and instead endowed us with whining about your frustration level... You didn't mention doing ANY of the troubleshooting steps you now describe. Yet another example of entitlement trumping logic.
The bottom line: Restore the phone as new (without restoring the backup), if you haven't done so already. If that doesn't work, you need warranty replacement of the phone.

I was playing Angry Birds and had to hit the pause button to listen to something. When I hit the pause/play button again to resume, I heard talking that sounded like a talk-radio program and I couldn't turn it off, even when I turned off my iPad.

Does anyone know what would cause me to start hearing a talk program of some type after hitting the play button after it had been on pause. Hitting the pause button shuts off the talking, but hitting the play button starts it up again. The strange thing is that the talking continues even after I turn off my iPad. The talk program was about silly or trendy news items, not regular news. It sounds like it could be a talk-radio program, but there were no call letters or information on where it was coming from or who was talking. The person doing all the talking is a male and sounds like he could be in his 20's. The only way I could turn it off was to hit the pause button and then turn off my iPad. I just got my iPad last week and had not had any problems with it until this happened. At the time this happened I was playing a version of Angry Birds that kept being interrupted by t-mobile commercials from time to time, which I had never experienced before. either.

Well, shut my mouth! There was a similar question over to the right about a 6th generation nano repeating over and over again -- I read the answer to that one, followed the instructions, and holy crap, it's back to normal.
Is there a name for this when you end up replying to your own aggravating question? That's what I did. Now I can go out and listen. It's only 91 degrees. Heaven. Thanks, Apple.
