Very loud fan (or other part?) noise in MacBook Pro

Greetings! My fan (I assume) has recently started making a very loud, horrible noise that sounds like a piece of plastic stuck in the spokes of a bike. It's driving me crazy and making me a burden to be around me when I'm working...which is always. Please help! I'd greatly appreciate it.

Perform a SMC reset:

If there is no change, open the MBP and examine it. Look for dirt an debris, and if found, clean it out. You will need a #00 Phillips driver.
If still no success it may be that the fan is faulty and should be replaced. Make an appointment at an Apple store genius bar for a free and definitive diagnosis. It is not an expensive repair.
Ciao.

Loud fan and metal cracking noise on Macbook Pro 13''?

I have the late 2011 model Macbook Pro 13''. The problem started out with just a loud fan, the computer started to operate really slowly and just yesterday I started to hear loud metal rattling on the inside. At first it was just when I turned the computer but now it will do it periodically while it's sitting completely still while running. It also is heating up a lot. I've already gone to Activity Monitor and killed all activities using too much CPU and the fan doesn't stop.

I have the same model and accidentally dropped mine off my bed today.
I looked around for a while to see what the noise could have been and found this
http://support.apple.com/kb/HT1935?viewlocale=en_US which seems to explain the problem, even if you haven't dropped yours. My fan has also been loud lately but it seems unrelated.
I'd suggest you try turning off the SMS and then back on.
I did that with mine and it hasn't made any more noise since. If that doesn't help, it's never a bad idea to go to the apple store to have it looked at. Especially for how expensive the computer is.

What is causing the very Loud Fan noise everytime I use the computer? What is causing the Heat as well? Please help

Please Help!
My computer has been making very LOUD fan noises. I know this cant be normal. How can I fix this issue?
This has been going on for a while now. As soon as I turn on the computer....the noise starts.

Go check out Activity Monitor on your Mac. It will show you which programs are running, and how heavy their use of your CPU is.
When mine does this, for some reason, I have a bunch of "Managed Clients" running at once. I use Act. Mon. to shut them down, and my Mac runs normally.

One of my fans is very loud, while the other one is fine, is this an issue?

Hello there, Snake97.
The following Knowledge Base article provides a great step for fans running at full speed:
iMac: Fans run at full speed after computer turns on
http://support.apple.com/kb/ts1433
In order to correct the issue, reset the SMC. Your iMac should now start up and operate as expected.
Thanks for reaching out to Apple Support Communities.
Cheers,

Very loud fan upon starting imac. Does anyone know how to fix?

My iMac has a VERY LOUD fan that turns on during start up and does not stoop. I tried to shut down and start up again. I also tried to unplug the machine overnight. Still happening.
Anyone have a solution?

This is a part of the larger MacBook Pro connectivity issue. There are several related threads dealing with the MBP's networking problems. If your unit is suffering from this type of difficulty, good luck ... (or a long ethernet cable)
(PS Everybody please make noise on this one so apple comes up with a solution.)

G4 not starting up, black screen, noisy fan, chimes OK then nothing, after a few mins very loud fan!

Anyone else had this? On start up chimes as normal but screen refuses to come on. Have swapped monitors and same happens on the newer one. G4 was making noises before last week with very loud fan cutting in from time to time. Got lots of work on that computer! Typical, not all backed up! Is it the logic board? How much does that cost to sort out?
Thanks for your help

Hello, it's going to be tough to find anybody to work on G4s these days, Apple doesn't.
Have you blown the dust out lately?
Does the Video card have a fan on it? Does the fan spin freely?
If worse comes to worse, you can pull the drives & get the info off of them with one of something like these...

Only part of my macbook pro keyboard backlight works

only part of my macbook pro keyboard backlight works , all settings and f6/7 keys work ok but only a triangle in the centre lights up, so the rest of the keyboard is dark.
Pleqase someone shed some light.
Bought in May 2012

It is likely a hardware defect. If you bought it in May of 2012, it is still under warranty. Take it back to the store or mail it in to be fixed.

Hi. I am preparing for CA Bar Exam. I am considering buying MacBook Pro for exam writing. One is 13 inch 1499 dollar 2.5 GHz 8GB, the other is 15 inch MacBook Pro 2.7 GHz 2799 dollar 16 GB. Both are retina. Which one is better for me?

I will use Barclays Card for 18 month free interest.
I wil ask Apple clerk to avoid LG monitor.
I will buy those in Apple store.
Which one will you recommend?

Tha's something you need to decide for yourself.
Do you think you need 16GB of memory or 8 will be enough?
Do you need to carry your macbook around with you more often? if so just get the 13" it's easier to carry.
Or maybe you enjoy watching media on a bigger screen?
As for word processing it shouldn't be a problem on both notebooks.
Also can you afford buying the 15"?
And what about the hard drive capacity?
So my advice is to consider these aspects, make a list of pros and cons and see what you come up with

Hp Pavillion dv7 - very loud fan noise (cracking)

My HP Pavillion dv7 starts up with a veqry loud fan noise.
It is still under warranty (hp care) tii 23/12/2011
Is the fan broken or can i resolve the problem myself

Hi,
If the fan is making a lot more noise than usual and sounds as if it's cracking, this is very likely to be a mechanical issue. By far the best suggestion I can make is that you contact HP straight away and arrange to have this repaired while the notebook is still under warranty.
The telephone number to arrange this can be found on the relevant link below.
If you live in the US, contact HP Here.
If you are in another part of the world, start Here.

Very loud fan noise

This has probably been dealt with, I have a 2007 intel iMac. It's been running fine but this week the fan has become very loud. Any ideas?

This can probably be reset by doing a SMC reset. Here is what to do on your iMac:
• Shut down the computer.
• Unplug the computer's power cord
• 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.
• Report back results to us.
Regards,

Brand new U500 has a very loud fan

I received this brand new U500 (customized on Toshiba.com) about 10 days ago - everything works great (love the back-lit keyboard) - but the fan noise is a little louder than what I'm used to. I had a 6-yr old Dell XPS with a quieter fan than this brand new Toshiba machine. Basically if I'm standing 20-30 feet away from the laptop I can hear the fan, and one can wonder if this comes from a refrigerator or a vacuum cleaner working in the background.
Has anyone had a similar experience - is this fan noise something I should just learn to accept or do you think I should do something before the computer comes out of warranty? I really would hate to have to return a brand new computer, but at the same time I think fan issues only get more numerous when a computer gets older.
Just for info, the machine is Satellite U500-ST6322, CORE 2 DUO P7450 2.1GHZ, 4GB RAM, DVD Slot load.
Thanks a lot.

Hi and welcome to the  forums.
you wrote
I've read that if I installed OSX 10.4 then the fan would run quieter.
Is this the case?
No, that wouldn't make a difference. eMacs are famous for their very noisy fans.
Some say they were originally intended as turbine impellers for Boeing, but were rejected as too large. So Apple picked them up, and modified them for use in the eMac.
eMacs were made to be workhorses in classrooms and their robust design includes that heavy duty fan, which does impose itself quite loudly.
Some people have installed a means to introduce resistance to the fan circuit to lower the voltage and hence the fan speed, in an attempt to quieten it down.
Whilst this practice seems to work, personally I would be concerned about that causing overheating as during summer things can get very hot here, though perhaps would be less concerned if living in the UK.

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.
