Anyone encounter loud fan sound upon power up?

Hi,
When I power up my iMac, I encountered a very loud fan sound in the background that I had never encountered before.
This happens despite turning off and powering up again.
Any idea what's happening? And how to remedy the situation?
Regards.

I would recommend downloading and running the popular, useful and FREE "iStat Pro" to see what the actual temperatures of your computer's inner components are. Then post the data here for us to see and comment. You'll find it here:

Hope this helps

My macbook pro i7 (2011 version) has a loud fan and high cpu % when I have Skype on or when I am on Safari. Help please!

My macbook pro i7 (2011 version) has a loud fan and a high cpu % when I have Skype on or when I am on Safari. My laptop would sometimes freeze for a while and it is usually hot. Has anyone else encounter this problem and know how to fix it? Thanks!

Skype is a very resource intensive activity...it has been reported on here users are seeing cpu temperatures on the order of 80-85 °C, within the limits of the cpu, but still hot to the touch.
Make sure nothing else is running so you keep the thermal load down.

Very loud fan sound, can't get video, system still running...help?

I can't seem to find an answer to this anywhere here or throughout google. Can't find a similar problem.
We have a G4 tower here at work that we run FileMaker server on. It pretty much just sits there and we all connect to it remotely and use the FileMaker on our own machines. It's usually not even touched unless Filemaker needs to be restarted or something along those lines. It shares a monitor with another system so its not usually even connected to a monitor.
Well - today there is a loud fan noise coming from it that we havent heard before. So we went to hook up the monitor and can't get any video. It was fine in the past week or so because we have been on it with the monitor.
FileMaker must still be running fine because we can still connect...for now...but we can't load up a screen to properly shut down, or run the backup or anything to safely turn the machine off. I am not sure which OS is currently installed because I can't get to that info.
Our guess is that the video card died, and that is the video card fan spinning...but if that were the case, would the software running still be fine like it is?
Any help would be greatly appreciated. Our tech guy can't make it out until tomorrow morning and we're afraid to have to wait that long...
Thanks in advance!

G4 tower covers a lot of G4s; it would help to have more specific model information. I think some of the later ones (not my DP800 QS) had software controlled fans. It's possible part of the operating system has crashed and the fan is automatically going into full speed to automatically prevent overheating. The rest of the OS may still be running and explaining why you can get to your files. I'm not sure about the video though. Perhaps somebody else has something more constructive but with that kind of thing I can't help but feel you'll just have to switch off the machine and restart it.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
* On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.

''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.

Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

HT1420 how do i deauthorize a computer i no longer have? or has broken down on me and never had a chance to deauthorize it

how do i deauthorize a computer i no longer have? or has broken down on me and never had a chance to deauthorize it

If you did not deauthorize before selling, you have to deauthorize all from your actual computer:
Remember to deauthorize your computer before you sell it, give it away, or get your computer serviced. Also, make sure you deauthorize your computer before you upgrade your RAM, hard disk or other system components, or reinstall Windows. If you do not deauthorize your computer before you upgrade these components, one computer may use multiple authorizations.

You don't mention what device and iOS version you are using so I'll give you a generic fix for now.
You can try resetting your iPad by simultaneously pressing and holding the Home and Sleep/Wake buttons until you see the Apple Logo. This can take up to 15 seconds so be patient and don't release the buttons until the logo appears.
Try to download and run the app again to see if the problem persists.

G4 MDD has REALLY LOUD FAN noise!

Hello All!
I've just purchased a dual 1.25 GHz MDD G4. It has a much louder fan than the Graphite G4 (Digital Audio) that I have been using. Is there anything that I can do about this? Is this a known issue... or maybe is it just this particular machine?
Thanks,
Mark

Just Wondering...
Are loud fans normal for these machines?
Yes. They were nicknamed "The wind-tunnel". The noise was so bad on the early models that Apple offered a free replacement power supply with a quieter fan (and a slightly lower power rating).

My ibook G4 won't start it shows black screen and loud fan sound only

my ibook G4 won't start, after you press the on key it makes a loud air sound, almost like a kernel panic sound, no screen light just the sound, it will turn off by pressing the on key again. Is there anything I can do to get it on?

Your very welcome.
You would need to apply pressure to the left side of the track pad about 2cm out. I found applying pressure to both sides of the track pad more successful. All you have to do is push down on the case, while making sure your iBook is on a flat surface. If you have someone willing to help you, you can get them to apply the pressure while you back up your files. Other methods would involve tempory repair or removal of the hard drive. If you remove the hard drive to be read by another computer, you would need a cady to put the drive into. These caddies are cheap enough. Would suggest you use a USB cady and plug your drive into that, which would act as USB external drive. I'd suggest you get a USB cady to remove your files, be careful to what operating system you have on the computer you are using to get the files off. Windows OS won't read a MAC OS X drive (extended journal format) It would need to be another Mac or a Linux PC.
If removing the hard drive is something your not to confident in doing, you could alway pay a computer repair shop to remove it for you. (Maybe they would have a USB cady for a 2.5 IDE hard )
Here is a link giving further details about this chip solder problem.

Let's hope just applying enough pressure is enough to get your files back up.
Best of luck!

Imac desktop is making real loud fan sound?

The imac screen went blank & black & when it came back on the fan is running really fast & loud. What's going on??

It crashed or shutdown due to possibly heat.
Have you blown the dust out lately? Let it cool for an hour & see if you can get these...
Get Temperature Monitor to see if it's heat related...

Too loud fan sound when play WOW

i have 5 giga ram. thanks in advance...

i mean what is the exact name. there are some model in ac company.

but available to mac slot maybe different story.

MacBook Pro has a loud fan

My MBP gets a new Logicboard and 4GB RAM. Now the fan is louder than before. How can I repair this??
It is the MBP with 8600m gt.

Ok, whenever they open for you.
The fans have 5950 bis 6007 rpm
The temps are: 24°C to 50°C
That's interesting. The highest temp is 50C, but the fans are running at maximum (about 6000rmp)? Mine are at "idle" speed, 2000rpm, at that temp and even when temps get somewhat higher.

Very loud fan sound after sleep when Ram is upgraded.

Recently I have upgrade the Ram memory from 1Gb to 5Gb with (2x2GB) FB-DIMM DDR2 667MHz from Ondamatica. Memory works perfectly, hardware tests were OK and i didn't notice any issue except one: after sleep, fans start to spin faster and faster (seems like a vacuum) to what I supose Is the fastest speed they support, during arround a minute or 45 seconds. That generates an intense noise but happens only when awake afer sleep, not when restarting.
I've done almost everything: reset pvram, reset SMC, change memory slots... And the issue only stops when I remove the new two Ram modules.
I've read about it in some forums, but no one solved it. ¿Any suggestion before I return the Ram to the store?. Could be a software problem?.

It will or can happen but you can reduce it somewhat maybe using SmcFanControl (2.1.3.1 - wwww.macupdate.com ) to keep the fans above default by 200 rpm. And run Hardware Monitor to monitor temps as well. They may be running much warmer than they could/should/ought to.
1GB and your system was on starvation express! ouch. 4GB is more of a normal minimum even. 4 x 1GB is nice balanced setup. 2GB DIMMs might be warmer, run 70C perhaps. And they use about 15W each.
