Fan starts running after 15 minutes very noisy. anyone with similar problems?

The fan starts after 15 to 20 minutes working with the MBair. Doe not stop. And it is quite noisy and disturbing. Anyone with a solution?

Believe me this is nothing unusual the F10 is a notebook with a strong GPU and CPU. These parts produce a lot of warmness and this must be cooled!
Please dont compare mobile notebooks fans with the Qosmio. The Qosmio notebook properties are similar to a desktop PC and in my eyes an desktop PC is much louder as the F10

Could be over-heating. Try cleaning out the air vents.

Another problem: fan starts running nonstop and messages says to restart

I recently had my hard drive crash and with help from this forum, I was able to replace the hard drive myself last week. I upgraded to Leopard and all seemed well. Now this has happened 3 times: the fan starts running nonstop and loudly and the computer displays a message that I need to restart my computer. The first time it happened, I restarted and it was okay for a few minutes, then started up again, so I shut it down for the night. The next morning, I reset SMU and it worked all of yesterday with no problems until about midday today, when I heard the fan going again and the same message displayed. I currently have it shut down and unplugged to reset the SMU yet again, but am wondering if this is a symptom of more serious problems?
The power supply was replaced a little over a year ago at a local Apple store. Of course, my AppleCare ran out about a month ago. I was really hoping to get another year or two out of this machine with the new hard drive! When I verified the hard drive yesterday, Disk Utility said it was fine. Are there any other troubleshooting things I can do? Thanks for any help with this.

Thanks (once again) for the help! That's a great web site. So far I have run Apple Hardware Test and it says no problems. I verified the disk and it says it appears to be okay. I repaired disk permissions and it did find a couple that it repaired. There were also several SUID files it said would not be repaired, but I found an article that said these warnings can be ignored. I will keep my fingers crossed that the disk permissions repair will help. Otherwise, I will call Apple and see if they will do anything for me. It doesn't seem like it is the power supply again, I'm having totally different symptoms...but who knows? I don't think I will put any more money into this Mac. I would probably buy a new one, but I sure would like to delay it for a year or two, if possible. When it's working okay, this computer is still more than adequate for everything I do.

My older mac book pro and iMac are both running 10.6.8 and both have started running safari and email VERY slowly. My new mac book pro running 10.9 is having no issues. Is anyone else experiencing these issues?

Satellite A300 - fan starts running every 2 mins for about 30 secs

Hi
I wanted to know if its normal that the fan starts running on my Satellite A300-1hv every 2 mins for about 30 secs?
This is happening continuously. I am on vista maximum performance power.
Help will be really appreciated.
Thanks.

Yes, this is nothing unusual because the fan starts rotating if a certain temperature level was reached.
There is an temperature sensor and if the temperature goes to a higher level the cooling modules begins to cool the internal devices like CPU, GPU.
If the temperature decreases then the fan slows down.
It seems there is nothing wrong and you shouldnt be worried

Workflow Agent Listener and Workflow Background program run after each minute

Hello,
We have scheduled Workflow agent listener program to be run after 5 minutes but it runs every minute more than once and fills concurrent request queue.
Please help.
EBS 12.1.1, DB 11.1.0.7, Linux 5.
Thanks & Regards

We have scheduled Workflow agent listener program to be run after 5 minutes but it runs every minute more than once and fills concurrent request queue.
Looks like this concurrent program was scheduled to run more than once? Maybe under a different application user?
What if you cancel the recent schedule you made, would you be able to reproduce the issue then?
Thanks,

What the...? Fan starts working after 14 months of zilch!

I bought a 24" iMac in August 2009 and noticed that it ran unusually hot. I checked a few forums and was told that this is normal, and the aluminium body acts as a heat sink.
I installed iStat Nano and it showed no fan sensors and temp only for the HD. So I used external fans (3) to cool it down all summer.
Two days ago, I accidentally disconnected the iMac from the power point and quickly plugged it back in -- and fans started blowing!
They're unbelievably noisy and I can't find any way to switch them off or turn them down. @#$%^&* cold, too! (Forget using Skype or microphones... way too noisy.)
No fan sensors showing still on iStat Nano, and temp still only shows HD.
Any suggestions?

Yes do a SMC reset and a PRAM reset, here are the instructions:
_SMC RESET_
• Shut down the computer.
• Unplug the computer's power cord and ALL other 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.
_PRAM RESET_
• Shut down the computer.
• Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
• Turn on the computer.
• Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
• Hold the keys down until the computer restarts and you hear the startup sound for the second time.
• Release the keys.

MacBook Pro's fans start running at high speed when the computer is asleep. Normal?

The other night, my MacBook Pro's fans started running at high speed when the computer was asleep. Loud enough to wake me up. And this just kept on going until I finally decided to turn the computer off. Is this normal? Is this anything to worry about?

This is not normal. See if a SMC reset solves the problem:

Sattelite A200-1N9 fan starts running faster and become loud

Hi,
So i have strange problem. When my fan starts running faster he bocome so loud i can't work.
What is more strange when he bocome loud i can't start any new programs and programs already running freezes.
What kind of sorcery is this?
Sincerely
Per Aspera

Hi
This happens because an process running in the background stresses the CPU up to 100% and this creates more heat dissipation and the fan kick on and runs faster to cool down the CPU. Additionally the CPU is locked and therefore the system freezes for some time.
You have to check what process or tool stresses the CPU.
You can start task manager (CTRL + ALT + DEL) and check the tab Processes.
Here you can see in the CPU column what process use most of CPU performance.

How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Premiere Elements 12 will not run after installing on my HP laptop with Windows 7.

Premiere Elements 12 will not run after installing on my HP laptop with Windows 7. HOWEVER, PE11, PE10 & PE 9 all run without a problem. I contacted HP, and there are NO NEW or ADDITIONAL video drivers available from HP.
I have NEVER had a problem running ANY software on this laptop -- except for PREMIERE ELEMENTS 12!

I recently updated? to Lion from 10.6.8(snow leopard), and things seem to be running slower. Has anyone had similar problems? I have Feb 2011 Macbook pro 13" 2.3 Ghz.

I recently updated? to Lion from 10.6.8(snow leopard), and things seem to be running slower. Has anyone had similar problems? I have Feb 2011 Macbook pro 13" 2.3 Ghz.

As Shootist pointed out, the system uses more power.
However, initially it will reindex the hard drive for spotlight, which will slow things down temporarily.
It also must rebuild caches that eventually will speed things up.
If it has completed indexing the hard drive (no dot pulsing in the spyglass), then there might be something wrong.
Start by booting into the Recovery HD (a partition created with Lion that has Disk Utility and reinstallation options) by holding down cmd-r when you restart. You can let go when the gray screen appears.
When it boots, select Disk Utility and Repair the drive.
If that doesn't speed things up, try re-installing the OS from the same Recovery HD. It won't delete any of your files, but it has helped some people whose Macs ran slow after installing Lion.
Also, how much memory do you have? Lion needs RAM so maxing your Mac out might also help.
