My Macbook's Fan Constantly Runs at 5600+ RPM

have noticed that for the past few days, my fan was running all the time,and very loudly from the time I turn it on, until I turn it off. I got istat pro and saw that my fan was running at 5500-6000 rpm all the time. Can anybody tell me whats going on?

Yes, do a reset and if you are running something like Parallels. It does use a lot of CPU cycles which heats things up. Open up your activity monitor to see how much CPU percent you are using when the fan is running high. It will also tell you what programs are using it too.

Macbook Pro fans constantly running, Safari hangs up and/or crashes often.

My 2012 Macbook Pro (10.9.2, 2 GHz Intel Core i7, 4 GB Memory) has been acting up a lot lately. The fans are constantly running even if major apps (mail, safari, itunes, messages, etc.) are closed. Safari, in particular, has been hanging up and/or crashing recently for no real apparent reason. My battery has been draining out faster than usual. I've always tried to be very cognizant to the health of my computers and phones and try to limit the amount of apps and files I download, sites I visit, etc. I've already done Verify Disk and Verify Disk Permissions in Disk Utility, reset Safari numerous times, disabled all extensions, removed unnecessary apps, and altered settings in Energy Saver, all to no avail. I'm a grad student so I only use my laptop for Safari and Microsoft Word and put it to sleep when not in use as often as possible. Also, my battery was at 56% about 23 minutes ago and is now at 38%.
Below is a list of the processes using the most memory in Activity Monitor:

have you tried resetting your MacBook Pro’s System Management Controller?

Macbook pro fan constantly running on high

Hello i have a problem with my macbook pro
as soon as i start my macbook pro early 2011 up the fan goes immediately on high speed and when i look on on istat it says that the fan in going 0rpm but when i push above the F6 and F7 it suddenly stops and the fan goes to 2028rpm i have tried the smc reset and such and that doesn't work at all. I have looked at activity monitor and there was nothing strange as well so please does someone know how to stop this, its really annoying.

Most intereseting. The display shows temperatures at very acceptable levels but zero fan speed. That cannot be. Try a Apple Hardware Test:
http://support.apple.com/kb/ht1509
You may have to use the OPTION and D keys to start it.
Lets see if that picks up anything.
Ciao.

My mid-2012 MacBook Pro has the fan constantly running. As soon as I turn it on. My MBP won't even be hot and the fan is running. How can I fix this?

If you are still under warranty and/or have AppleCare, call them. Let them deal w/it.

MacBook Fans Constantly Running

The fans on my MacBook pro are constantly running. This morning I turned it on and they started up within the first 5-1o minutes of using the machine.
Has anyone else had problems with this? I have two other co-workers who are doing the same amount of activity I'm doing and we have the same exact hardware set up, but they aren't having any problems.
Help!
Thanks!

Have you been monitering Activity Monitor as I suggested to see if an application is causing the problem?
I would also suggest using a utility such as TinkerTool System to erase system, user, and font caches in case the problem is caused by a corrupted cache file. Restart after clearing caches. Also use the utility to run the Unix maintenance scripts. See the following for more on maintenance:
Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.1 or higher are Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. Versions 1.5.1 or later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts had been significantly reduced in Tiger and Leopard.
OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline. Note that presently AppleJack is not compatible with Leopard.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
7. SuperDuper! (Commercial)
8. Data Backup (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at www.versiontracker.com and www.macupdate.com.
It also can't hurt to do this:
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 and 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 (4.0 for Tiger, and 4.1 for Leopard) and/or TechTool Pro (4.6.1 for Leopard) 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.

Why does the fan constantly run

my fan on my macbook pro is constantly running today? any answer as to why

Hi Julian,
MBPs run very warm. The fans run to cool the CPU etc. The warmer it gets on the outside, the harder it is to keep the inside cool. There can also be issues causing the MBP to run warmer than usual.

Cooling fans constantly run @ full speed after replacing the upper CPU??

After replacing the upper CPU on a Power Mac G5 (June 2004), Dual 1.8Ghz PowerPC, model M9454LL/A, all the cooling fans constantly run at full speed. All other operations are normal.
I've read, "...after replacing or switching CPU locations the Logic Board doesn't properly recognize the CPU's in their new location and a "Thermal Calibration" is needed". Could a "Thermal Calibration" possibly correct the constant full fan speed issue?
What software would be required?

Hi-
Could a "Thermal Calibration" possibly correct the constant full fan speed issue?
Yes.
What software would be required?
The Apple Service Diagnostic disc (ASD) of the proper version for your machine.
Call an authorized Apple service provider and arrange a calibration, as the disc is not readily available to individuals.

Cpu fan is running at -1 rpm!!

h, i've been facing slight problems with my mac that it overheats sometimes, so after some research i found out that i can download a program called fan control where i basically can control the speed of my fans. then i found out that my cpu fan is running at -1 rpm, the desired rpm is 300, my other fans (hd and dvd) are running at the desired rpm, i'm not sure if i should be worried!!! i mean do i have to replace it!? and if so where and how!!!?? btw i've just got this laptop used, it's a 15" late 2008 with the highest configueration.

Resetting the SMC was my first thought, but you have done that. You might also try resetting the PRAM/NVRAM:
http://support.apple.com/kb/ht1379
After that if the issue persists, I would call AppleCare.

Post serviced IMac and the fan is running at top RPM.

I had my IMac serviced doe to the HDD dieing. When I got it back, the HDD fan is running at max RPM. I've tried to reset the PRAM (7 times, over and over) and tried to reload the SMC patch and no luck. Apple Store is over 2 hours away so I'd like to save 8 hours on the road by figuring our if there is anything else that I can try to fix this.
C2Duo IMac with Tiger and the 'fans played on' from the moment I got it back and started restoring the data.
Any ideas?
Also, a new AppleCare agreement talks about 'onsite service'. Do they actually do onsite service? Does one have to request it? It wasn't offered when I called in after finding the fan issue.
Thanks!!!

So, I called AppleCare and they walked me through an 'SMC reset' routine and now SMCFANCONTROL doesn't run AND all the fans sounds like they are running at full speed.
I got a call that they want to swap my system rather than have me wait for a new sensor. I wonder what issues I might have with a 'refurb' system.
There is another issue, there is a smear of some kind of glue on the screen from the service experience.
It's been interesting dealing with their support...
I can't stand the whine of the fans and now am back on Windows for most things. Yippee...

What is causing my Macbook Pro fan to run constantly?

Hello. Recently my Macbook Pro fan has begun to run constantly at high power. I've checked the activity monitor and even when there is little RAM or CPU this occurs. I am wondering if the issue is the hard drive because the I am seeing spikes in disk activity at random times even when I am not using the hard drive. The computer is actually heating up when the fans are on at full power, so this also leads me to believe it could be the hard drive. I have already tried resetting the system management controller. Any other ideas? What should I do about this?
Thanks a lot.

Try raising the the the machine with wood, or , plastic botttle caps t get it up an inch or so, that way there is more air flow under the MBP to help with the air flow to help keep the cooling more een. Hope this helps.

MacBook fan constantly running after recent updates

Ever since I installed the QuickTime/FrontRow/iTunes update of the other day, my MacBook's fan has been running constantly. I have rebooted, reset the SMC, checked Activity Monitor for any rogue processes, reinstalled the updates via the downloads from Apple, etc., and found nothing out of the ordinary. I installed iStat Pro's Dashboard widget to monitor the speed, and it shows it as running from 5300 - 5800 RPM regularly even with nothing intense going on. This doesn't seem normal, as before the fan would only come on when I was doing something CPU-intensive. Any ideas?

I finally found my issue, it was NOT the recent update (at least on my machine) but my printer queue.
When I print from my MacBook I do so wirelessly through a printer I connect to a different Mac just for this purpose. BUT, this time I disconnected the Printer from the other machine apparently before two of my jobs had been able to print. Thus, for the last three days each time I turned my Mac on it would endlessly look for the printer and attempt to print. This could be seen under Process ID 0, called "_PrintJobMgr".
THE FIX:
All I needed to do was go to System Preferences -> Print & Fax-> then delete any open jobs.
So, this was my fault, but it would be nice if the software was smart enough to kill these jobs on its own.

Mac Book Pro fan constantly running

For a couple of days the fan of my (15" late 2011) MacBook Pro has been constantly running and the Mac has become sluggish. The CPU temperature is 156 °F. It seems that the problem would be caused by "coreservicesd" process taking a huge percentage (57%) of the Mac RAM.
What is wrong? Restarting the Mac does not help. Thank you.
I am running OS X 10.9.3 with 8 Go. RAM and 500 Go. HD

Fan Constantly Running. Choppy Video. Slow Loading. Comp is Slow to Typing

A week ago my Macbook started to perform slowly. My fan is constantly running and my battery and the area around it is wicked hot. Video is choppy but the audio is streaming fine. Web pages are slow to load and when I type, the screen is a second or two behind what I'm typing.
I've looked for new updates but none are out currently.

Did you look at Activity Monitor? Did you check if the battery is deformed? Is your ram working properly - try memest for osx - and seated properly?

Macbook Pro Fan Continues Running After download Error -- Please Help so Loud

Hello,
I recently tried to download the Citrix reciever application onto my Macbook pro. The installation was taking an excessive period of time and it was obvious that something had gone wrong in the download because it had taken several hours and was stuck at a certain step. I tried to cancel the installation but it wouldn't allow me. So I force quit the installation and thought that it was shut down, but I was mistaken. The next time I opened my computer the fan was running at an increased rate and was very loud and the computer was heating up. I tried to restart the computer and it said that the program was still trying to download and that the computer could not be shut down until completed. I got frustrated and basically forced a power down by signing out and holding the power button or something of that nature till it shut down. I waited overnight and then powered it back up but nothing had changed and the fan was still running like crazy but it says the program is not trying to install anymore though. I checked the activity level and CPU but nothing is out of ordinary of high. The program is not anywhere on my computer either so I have no idea what is going on and cannot figure out how to stop this fan running like this. It is draining my battery, overheating my computer and is annoying too.
Any help, hints or ideas would be greatly appreciated or I will be forced to visit the apple store for some help I guess.
Thanks,

Unfortunately, spoke way to early. The fan issue is still a big problem. From the second the machine is turned on, the fan cranks up. Frankly, I think this is overheating the machine to some extent (running the fan at max speeds when it's not even warm). Additionally, the noise caused by this has only gotten worse, and now it is even making a "whistling sound." Looks like I'm going to be making the trek to the Genious Bar, but based on comments by others on this issue I am not optimistic about a fix.
