Macbook Pro fan running at high speed but is not experiencing heavy usage
My computer is 3 years old and I've had no problems.
A few days ago the fan started whirring incessantly after the computer had been on for only 10 minutes or so, even when experiencing minimal usage.
This could be just a coincidence but the issue started about the same time I installed the latest security update, I'm on Yosemite.
Can anyone help?
The first thing to try is a SMC reset.https://support.apple.com/en-us/HT201295 Also check for run away apps. https://support.apple.com/en-us/HT203184 You could also make sure the back vent is not getting clogged.

Macbook Pro Fans Running At High Speed
My MBP 17" CoreDuo 2.16ghz came back from having the Logic Board replaced at the weekend. All is well except that now the fans run at high speed all the time.
I have installed SMCFanControl, and the current readings are 45 / 113 degrees and the fans are running at 5500 rpm. I took the machine back to the Apple store but when I was there the fans didn't go above 3000rpm (typical huh?). It's nice that the case is now a lot cooler than it used to be but the fans seem very loud to me.
The question is, is this normal? I am not running anything very heavy duty at the moment. Any ideas?
Thanks
MattI tend to agree with Ned on SMC fan control (that it arguably causes more problems than it solves).
I had a similar problem with mine recently having the fans run constantly and at full speed. My temperatures never approached yours, but it would fail to go to sleep etc.
I would start with the advice Ned gave you. This is the same path Apple Care led me down in trying to resolve the issue.
Ultimately though I had to do an archival install of the operating system. It is non-destructive so it wasn't a big deal. I just had to slowly re-install patches and observe behavior. Oddly I was able to patch back up to 10.4.9 without the issue re-occuring so the root cause is still a mystery to me.
edit
Patch gone bad maybe? I tried re-applying the 10.4.9 combo before attempting the archival install route with no success. I know that has been suggested many times. Apparenty it solves many issues, but it failed to solve mine. -
Why does my mac pro fan run at high speed?
My Mac Pro cooling fan started running at high speed. Tried all the shutdown and restart options but didn't help. Suggestions?
The fan runs if something is overheating or if a sensor has failed or there is a problem with the SMC. So, reset the SMC - Intel-based Macs: Resetting the System Management Controller (SMC). If that does not stop the fan from running then check for a runaway application:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
If the problem still persists then create a new admin user account, logout of your account and log into the new account. See if this fixes the problem.
If none of the above help, then you may have a hardware issue such as a defective sensor. -
2009 17" Macbook Pro fans running at max speed aafter hard drive upgrade.
I recently picked up a 17" 2009 unibody MacBook Pro with Intel Core 2 Duo 2.8ghz, 4gb RAM, SuperDrive and a Samsung 1TB hard drive. The system did not come with the original hard drive and I don't have any other hard drives to test and verify that the new larger hard drive is the cause. I have tried a clean install of Snow Leopard, Lion and even Mountain Lion but no matter what my fans always running at max speed (5k+ RPM). I have looked at iStat and the temps of any of the components in the machine never show more than 42*C so the fans should never be running at full blast. Oddly enough smcFanControl shows 0* temp but fan speds for both left and right are always 5.5k+ and very noisy. Using HDD Fan Control I am able to get at least the right fan to run at a controlable speed but its silence is drowned out by the left fan that still runs on full blast. I have already done multiple SMC resets and PRAM resets with no change in the condition. These noisey fans are driving me insane! I have run every available update as well. Is there a chance that the hard drive or something elses temp not being supported or detectable by OSX is causing the fans to default to the fail safe constant high speed?!

I will have to try that when I get can find the original discs because I have been unable to boot into the diagnostic utility with my Snow Leopard, Lion, or Mountain Lion discs. More than likely I am thinking a sensor failure because even booting into Ubuntu Live USB thumbdrive the fans still run at max.
Well your just a regular pirate. There is no Mountain Lion disks, it's not even out of Beta and avaialble to the public yet
We thought you were just mistaken but now your tech handy enough to boot a Mac off a Linux live USB, so that means you've been bad and downloaded MT Lion off a P2P network or something.
If your beta testing 10.8 your bound to secrecy and not allowed to be discussing it and posting this sort of question on this forum, but the other one.
If you know anything, OS X must "talk" to the hardware or else the default setting is to race the fans. Linux doesn't do this by default as it's designed for generic PC's which a Mac may appear to be one it's not really. Apple only supports OS X and Windows 7 on Mac's, not Linux.
Obviously something on your machine is SEVERLY messed up in hardware, likely a dead sensor, you bought a used lemon that someone didn't want to pay to get fixed.

Macbook Pro Fans Running At Full Speed When Macbook is Very Cooool
Ok, So now i'm pretty sick of the fan noise.
I've done PRAM reset, Power Management Reset to no luck.
So i decided to do some experiments.
As soon as the computer starts, Fans spool up to 6,000 and stay there. CPU Temp 42 Degrees Celsius.
Now My CPU temp does pretty well staying there. In Activity Monitor, No Processes of what so ever. Computer idles at 99% and only 1% being used by system.
So i decided to put the computer in the fridge. As soon as the temps went down 5 Degrees, to like 30 to 35 Degree Celsius, Fans idled at 2000 and as soon as the CPU temp is 40 Degrees, Fans spooled up and kept going all the way back to 6,000.
See as the temp drops on the computer, the fans do slow back down as the CPU temp drops from 40 to 35.
I called apple and the apple tech i talked to said that it seems the fan specs might be set out of whack. Meaning, the temps as which the monitor spools up the fans is set to low. He said it should be around 50 to 60 even 70 Degrees Celsius's before fans should spool up. He said the problem isn't the monitoring system since it does appear to be slowing down and speeding up the fans between 30 to 40 Degrees but it's spooling the fans up and to low of a temp than needed. He told me to take it to a Mac Genius sometime soon.
so before i do that, any apple geniuses what to take a stab on whats wrong and why it's doing this?My fan runs continually, BUT, with several monitors watching core AND fan exhaust temps I have noticed something strange. The core indicates 28C while the exhaust jumps from 42C DOWN to -128C and then the fan races. While this is keeping the book cool as a cucumber it is driving my wife and now me up the wall. NO I don't have any hung processes. NO the CPU is not caught in a cycle requiring massive computing power. Regardless of the temp the fan runs at the 6200RPM max. Zapping PRAM and resetting the System Management will soon be followed by gravity resetting through my 2nd story apartment window. One way or another this needs to stop!

Macbook pro fans running at 6200 rpm,running slowly and 35deg C?
About i week ago i was noticing significant slowdown in the operation of my mac. Yesterday the slowdowns were so much so as to render it useless.(30+seconds to realize that i had scrolled). I had just downloaded SOPHOS...it found nothing. so i assumed installing it had done something. i proceeded with a clean instal. After a few trys i was able to reinstall and boot up. The computer is functioning but not at the level of a wiped mac. there is still lag as i write this sentence, and at almost every action i see the pinwheel. I did a reset of the SMC and there are no hogs of CPU in the Activity Monitor(All programs). I downloaded a wiget to allow me to see temperature and fanspeed. the highest temperature is 35 degrees C and that is of the CPU, yet my fans are still posting speeds of 6204 rpm.
To make matters worse i'm overseas and cant seem to find information on a genius bar near me.(Toulouse France)
I feel like ive tried everything.
-Highfan speeds
-Laggy functioning (akin to a 5 year old PC).

I find it incredibly coincidental this happened the day steve jobs died....
Thanks for any help or advice you can offer.Backup your files before doing anything. May be a dying hard drive, would account for slowness. Software update fully.
Perform a hardware test
https://support.apple.com/kb/ht1509
that should tell you if it's a bad sensor or something
And yes, perform another SMC reset because your symptoms are typical

MacBook Pro Fan running fast after Mavericks update
Hello All! I have a 2009 MacBook Pro 13 inch and I have noticed that after I updated to Mavericks my fan has been running really fast and my computer getting warmer than normal. It's always on a table so there is nothing blocking the port in the rear. Any ideas on how to fix this?

Early 2008 MacBookPro keyboard backlight off and fans run at high speed
Hi!
I wrote from Turkey.
My Early 2008 MacBookPro 2.40 ghz 4 gb Ram OSX Mavericks machine's keyboard backlight off and fans run at high speed; it seems an exact smc resetting problem.
So i tried the 2 ways of SMC restting procedure; both battery you can move and not, but nothings changed on the situation..
On the way for removable battery; nothing changed but on the way for umremovable battery way; keyboard backlight flashes and gone, but fans are at high speed not changed. So nothing changed.
What can i do right now? i'll wait for your advices
ThanksYour Mac may need a new PRAM battery. Once it is over 4 years old, that often is needed.

My MacBook Pro fan runs while sleeping
My MacBook Pro fan runs constantly, even while sleeping.
The problem started about 2-3 months ago, but was pretty rare. When I noticed the problem, I would restart the computer and it would stop for 1-2 weeks. More recently it has become more constant, and now it always has the fan running when it's sleeping.
Any ideas on what I should do? Thanks!Mine too. If you're worried you might like to try a laptop cooler like one of these:

Fan running at high speed (iMac 2011)
I'm using an iMac mid-2011 model, 21.5". For the past few weeks, I'm facing an issue where the fan runs at high speed (>3900 rpm). This generally happens when I use the mac for more than an hour with simple tasks like browsing, checking mails, working on word / powerpoint, etc. If I play a game or watch a video, it happens faster in 15 - 30 mins.
I've tried SMS reset several times but it did not help.
I also ran the apple hardware test (extended testing) and got the following error:
4SNS / 1 / 40000000 : TS2p - 121.250
Could anyone help me understand what this error means?
Thanks.There is a sensor error. That is most likely why you are experiencing the problem. Take it in for service.

Mac running slow and fan running at high speed
MacPro1,1, osx 10.7.5, 8gb ram
My mac is running slow and fan running at high speed & very loud. On MRI diagnostic it passes everything except this error "CPU Proximity: Can't Read ". I did low level configuration and still having issue with unit.See Below.
Mac running slow and fan running at high speed -
Resolution changed on remote display. Fan runs at HIGH speed.
Today, for no reason, resolution changed on remote display. Option needed no longer shown. Tried SMC and PRAM resets. Now resolution on the MAC AIR is messed up (not full screen) and the fan runs at HIGH speed. This is a sudden change. Have been using the MAC Air in this exact configuration for 2 years. Tried restart/reset of monitor. Nothing. Did resets on MAC and screen changed there. Also the fan runs at high speed.
