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.

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 myselfHi,
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.

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.

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. -
Hi there,
I have a Imac G5 Rev2 and I read a lot of topics about loud fan noise. I bought an Imac about 4 months ago and the fan noise is a bit louder than when I just got it. What do all the users mean by "loud"? It is only once, when I was running the hardware test, that I heard my Imac did the "airplane" (very loud) fan noise. When I am using applications using a lot of CPU, I hear a louder fan noise but not the "airplane" noise.
Then what is the most reliable program to check the temperature of the iMac G5?
Which range of temperature is normal for the iMac?
Thx in advance for ya replies....I have a Rev b just like you and light use the temp of the cpu is 65-68º C while the hard drive is about 53º C. This is the temp as I am using two browsers, with iTunes and MS word open and running.
For a temp program you can try Temperature Monitor at this link:
http://www.bresink.de/osx/TemperatureMonitor.html
You can also try the very handy iStat Pro Widget (Of which the temps I gave you above came from). It has a lot of very useful data, from CPU to Memory usage, from CPU to Hard Drive temps---and even the speed of all three fans. You can find that here:

Hope this helps. -
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.

My Macbook Pro is 3 months old and recently it has been making quite a loud fan noise whenever i play music/video or even turning up the volume. I haven't been playing music/ video for ages. Is there any solution?

I turned on my new imac for the first time and it is making a loud fan noise please help
I just got a new computer and when I turned it on for the first time it started making a loud fan noise. the noise seems like it is coming from the back speaker. and it does not make the noise on sleep mode.
Connect the iPad to a USB 2.0 port your computer with the cable and iTunes should launch and it will take you through the process step by step.
I assume that your computer meets the requirements and that you have the latest version of iTunes on your computer. -
My 2008 Macbook Pro makes a loud fan noise.
Hello -
I bought my 15" macbook pro back in October 2008. I was very happy with my purchase due to the machine's performance. But over the past year I have noticed an increase in the fan noise. It almost sounds like it's hitting against something at a very high speed, hense this irregular fan noise. The noise also increases drastically when I am working on Photoshop or InDesign. I also partitioned my hard-drive to hold windows so I can work on AutoCad.....noise increases also as I work on my machine.
Why is this happening? Could this loud fan noise damage any internal component to the machine? Should I bring it in to Apple immediately?
Thank you!Some of the applications that you mention are somewhat CPU intensive which creates heat and results in fan speed increase and hence additional noise (to state the obvious). However if you are experiencing excessive noise when CPU loads are modest it could be that your fans are failing as all mechanical devices eventually will or you may have 'schmutz' inside that is the cause of the unwanted noise.
I suggest you open the MBP and see if there is any dust in the fans that may very well be affecting their performance. After 4 years, this is not an uncommon situation and it could be the solution to the problem.
If not, then you may consider getting replacements from iFixit or Powerbook Medic and replace them your self. It is not rocket science in this instance. If you suffer from chronic fingerfumbilitis, then have the Apple store do it for you.

X200 is suddenly emitting a loud fan noise
My X200 has been working perfectly since October. Now, almost a year later, it suddenly started to emit a loud fan noise (almost as if something fell inside the fan, although nothing did). Has anyone experienced fan failure on the X200? How can I get it fixed? I'm on a long trip in Europe and need to use it on daily basis. It's quite embarrasing to turn the machine on in public places.
heretohelp - if WaleedBakr's system is under warranty then of course it would be covered. no one is claiming otherwise or denying him of service.
regarding Lenovo knowing "exactly what is wrong with [his] computer", that depends entirely if a call has been made to service. it sounds like the issue may have cleared itself and that a service case hasn't been opened.
regarding this post going so long without a response from a technician, this thread was started on a saturday (in the US) and our forum doesn't have technicians roaming around. this is a peer-to-peer forum, not an official support channel.
i recommend familiarizing yourself with our community participation rules where we outline the objectives of this forum and rules of conduct.
if you have personal experience with this same issue happening on multiple X200 systems then i suggest posting about it in this thread so the information can be logged. that would be very helpful.

Mac Pro will not boot, constant loud fan noise and nothing else
hello,
earlier tonight,i put my mac pro on sleep, then later on, when i wanted to take it off sleep and use it, it made the loud fan noise, which it always does but goes away, but this time it the fan wount slow down and the loud noise stays and i dont see anything on the screen. im guessing the fan noise is the ATI x1900 card...
any help please..i just bought it 2 months ago...Hi, here are the steps I would go through. I would unplug the Mac Pro completely from everything and look at the video card's fan intake to make sure it isn't plugged and just make sure everything "looks" correct. I would then plug the machine back into one monitor/keyboard/mouse (leave all the other peripherals disconnected. Once that is done push the power button. Does anything happen? If not then if you have another mac and an external hard drive, make a copy of the OS on the drive and see if you can get the Mac Pro to boot off that drive. If the video card doesn't work then it will not show anything when booting off an external drive. If the external boot does work then I would suspect that you have a bad hard drive (or it crashed). At that point I hope you have a back up of all your data and such.
Mind you these are steps I would go through. What a nightmare. One other thing to check, make sure your monitor didn't die.

I had the same problem, one of my fans was making a loud noise even when my computer was just idling. It can occur because you dropped the computer, thus damaging one of the fans, or the fan broke down partially. I took mine to the Apple genius bar and they ordered a new fan for me and installed it in under a week (all covered by warranty). This is likely a hardware and not software issue, the only way for a fix is taking it to a genius bar. -
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.)

Hey everyone!
I just got a new u310 a few days ago. It has Windows 8 installed. I started working on the notebook, hoping the fan noise would eventually stop but it is really really noisy. I installed a software, which would indicate a temperature of 36°C, so usually the fan shouldn't be working on such a high level in the first place. I have read a couple of posts about this, but no one seems to have found a solution for tge U310 specifically.
Does anyone have the same problem? I thought maybe there is a BIOS update which would help...?
Thanks a lot,
Sonnihi Sonni_87,
The loud fan noise that you're hearing, is it a:
1. A wind noise?
- If it is, this is normal as faster fan speed causes wind noise on the vents (this usually happens if you're getting unusual heat and the fan spins at a higher rate to cool down the CPU/GPU.
2. A grinding / rattling noise?
- this indicates that the fan is struggling - It's possible that it's hitting something, is dirty or is starting to wear out and needs to be replaced.
Also, the BIOS can configure on how the fan spins. It's possible that the configuration is set to make the fan spin at a higher rate even on less load on the CPU/GPU (like in this article). In this case, you may need to contact lenovo report this issue

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 helpHello, 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...
