2008 macbook loud fan

The fan in my late model 2008 macbook sometimes gets very loud and the only way to stop it is to put the machine to sleep, but when it awakes it staerts again after 5 mins.

Resetting SMC may help.

Late 2007 Macbooks Loud Fan

I recently have gone through 2 late 2007 black macbooks. I have noticed their fans are much louder than the previous version of macbooks. Has anyone noticed this? or is it just been very bad luck with my two laptops.

Hi,
I don't know but maybe this will help, with the stock 160gb hard drive, the fans kept running every 10~15 minutes, but I have replaced that hard drives with both a 250gb hard drive and 320gb hard drive.
With the 250gb hard drive, the fan hardly ran (unless I am in Boot Camp).
But with the 320gb hard drive, I have never heard the fans run so far, (but I have not yet installed Windows for Boot Camp yet).
I also get much cooler temperatures every time I have upgraded my hard drive, right now every temperature reading is under 110*F.... And my fans always stay around 1785~1800 rpm
However, my late 07' macbook fans were much quieter then both of the macbooks that I bought in October (pre-Santa Rosa).
Hope this helps you in some little way, and Happy Holidays!!!

2008 macbook pro fan runs hot

My mac runs really hot, is there something I can update in the OS to help fix this? The monitor is starting to separate from the back (seriously) form the heat. I use my mac a LOT and I have two small kids so it's been bumped around a few times, so who knows if that had something to do with it and I plan to take it to apple to have it looked at (after I back it up this week) but was wondering if there was a fix for it running hot. It almost burns my fingers above the keyboard at the top if I touch it when it is running hot (if I have a lot going, illustrator, photoshop, dreamweaver etc).

I've had the same problem ever since installing Snow Leopard. Random high heat even with no system activity. One thing that seemed to help slightly was to un-check the "Open in 32-bit mode" checkbox in the "Get Info" window of Safari. This seems to avoid using the 32-bit version of Flash.
Another temporary fix that I found elsewhere in the discussions is to shut the MBP down, remove the battery and disconnect the power cord, then press the power button for 5 seconds. Re-install the battery, then boot. This supposedly does a partial reset of the PMU (Power Management Unit.)
I haven't had the problem recently (in the last week or so, knock on wood) after installing several seemingly unrelated updates. I have installed the "ProKit 6.0.1 (SnowLeopard)" update and the "Java for Mac OS X 10.6 Update 3", but NOT the "MacBook Pro SMC Firmware Update 1.4" since my MBP doesn't qualify.
My MB Pro runs cool now, except when Time Machine is grinding away. The updates may or may not have fixed the problem. Good luck.

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.
Ciao.

Loud fan when opening macbook

Hi,
Since the other day whenever I open my macbook the fan is very loud intermittentley for about a minute and then stops completely until I close it and open it again.
I have an early 2008 macbook. The problem just started a few days ago. We recently reinstalled Lion but have since downloaded a few things. My macbook doesn't feel warm at all.
Thanks!
Please let me know if there is any other information I have to give you.

Try resetting the SMC
Shut down the computer.
Disconnect the MagSafe power adapter from the computer, if it's connected.
Remove the battery.
Press and hold the power button for 5 seconds.
Release the power button.
Reconnect the battery and MagSafe power adapter.
Press the power button to turn on the computer.

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.

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.

Macbook pro retina start to make loud fan noise and work slow

I bought macbook pro retina display less than one years ago. For some reason my macbook pro has been making loud fan noise for about five mounth. Whenever macbook pro makes the noise, all the programs start to run slow. Typing, opening safari, and etc takes forever. It takes 20min to 40min for the noise to stop. At first, the macbook pro made noise once or twice in a day, but now it's making the noise frequently; It happens every 2-3 hours. It got to the point where it start to annoying me. Is there a way for me to fix this issue? If not, can I use one year warrenty to fix this problem? Thank you.

If your Mac works slowly when fans turn on, it's quite possible that there's a process which is eating the CPU and/or RAM.
Open Activity Monitor (in /Applications/Utilities), select "All Processes" above "Show" (in the toolbar) and then, order the processes by CPU usage. Do you see any process which is consuming more CPU or RAM? If so, tell us the name.
Additionally, you can reset the SMC > http://support.apple.com/kb/HT3964

MacBook Pro Not turning on, loud fan

My friends 13in MacBook Pro won't turn on. The light on the bottom near the remote reciever is on and there is a very loud fan noise.

If the light is on and the fan is running then the system is on, even though you can't see anythinig on the screen.
Press and hold down the power button for 5-10 seconds to shut the system down. Once that light goes off and the fans stop spinning try to start it again by just pressing the power button once. If you get the startup chime and something on the screen then it might be ok and it was just hunge. If there is nothing on the screen and it doesn't give the startup chime thenn the system needs to be taken to apple to be looked at and diagnosed as to the problems with it.

Loud fan noise on mountain lion, Mac Pro early 2008

Hi there,
I've recently installed mountain lion 10.8.5 lon my Mac Pro , early 2008, 2,8 GHz, 24 gb ram, 2x ATI Radeon 2800 XT.
To give it a clean shot i clean installed it on a sep. Partition, no upgrade from my previous Snow Leopard.
The Machine usually works quiet, i've measured via Isat Menu:
exhaust fan: 681 rpm
HD/expansion: 1100 rpm
After running Mointain Lion, latest update version, i get a much louder fan noise than in snow leopard:
exhaust fan: 845-950 rpm
HD/expansion: 1500 - 1800 rpm
The activity monitor shows no significant CPU usage, only the kernal has over 90 threads constantly running.
I've heard that this is a known issue but it's never been resolved. SMC and PRAM reset did not work at all.
when i go back to snow leopard everything gets back to normal. Yosemite is even harder on fan noise than mountain lion
so i've rolled back to mountain lion.
Any idea ?

no one here with the same problem on an early 2008 Mac Pro ?

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?

How to get rid of the "Other" in storage? Is this related to my MacBook's fan becoming louder?

My MacBook finally reached its max capactiy and approximatly 75% comes from "OTHER". What am I looking for to delete these items?
Also, coicidence or not but my MacBook all of a sudden started making sounds similiar to a louder "fan" noise. Is this a seperate issue or is this related to my storage filling up?

For information about the Other category in the Storage display, see this support article.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. Then reboot. That will temporarily free up some space.
According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown asBackups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Reboot and it should go away.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
Proceed further only if the problem isn't solved by the above steps.
ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
Back up all data now.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install ODS in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The application window will open, eventually showing all files in all folders, sorted by size with the largest at the top. It may take a few minutes for ODS to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
When you're done with ODS, quit it and also quit Terminal.

Loud fan like noise coming from 2012 Macbook Pro 15 inch but gets quieter when my palm is placed on the right side of the trackpad.

Hey,
I just got a Macbook Pro 15 inch. It is the preconfigered one with higher specs. I noticed that there is a loud fan like sound coming from my laptop. The strage part is, when I place my hands on it to typle, specifically the right hand. The sound gets cut to be about half as loud. I don't notice the sound when I am in class when there are people talking and the air is on in the room, but when I am in the library it is really loud. Does anyone know what this might be. All of my friends older Macbooks are dead silent.
This is not the buzzing or clicking sound that you can hear from a hard drive, it sounds almost like a computer fan, and it does it from the second the computer is turn on, to the second it is turned off or put to sleep.

Why does my MacBook Pro suddenly turn really really slow and make a really loud fan noise?

Whenever I turn on my MacBook is runs perfectly fine for 2 minutes but then it turns really slow (to the point that it takes ages to move the mouse cursor and to type) and make a really loud fan noise. What should I do to fix this?

Welcome to Apple Support Communities
There's a process that is taking up the RAM and CPU. Open Activity Monitor (in /Applications/Utilities), and select "All Processes" above "Show" in the toolbar. Then, order processes by CPU, and tell me which processes you see that are consuming more CPU
