Mac fan running too loud after update

I have a Macbook pro 13". (mid 2012)
Memory: 4 GB 1600 MHz DDR3
Processor: 2.5 GHz Intel Core i5
Storage: 500 gb
After updating to Yosemite 10.10, my macbook pro's fan is running too loud and producing a lot of heat. I reseted the SMC several times but it didn't help. Surprisingly, The fan also runs loud even if only 1 application is open.
Please advice me what should I do.
Thank you in advance!

I have the same model and I've had the same problem for a few days. I didn't really have problems with heat, but my fan was going crazy even though I was just browsing the Internet. Maybe you're logged into iCloud and have some activity going on. What worked for me was going to:
1. System Preferences
2 iCloud
3. Uncheck things like "Keychain", "Find my Mac", etc. (things you don't need/use)
For me, I unchecked everything and logged out of iCloud. After several minutes, my fan is super quiet and not acting up! Hope this helps.

Fan runs too fast after SMC update

About a week ago I updated the SMC of my Macbook 7.1 (mid 2010).
I even leaved it sometime (days or weeks) on the list of software updates without installing, as it said I should not touch until it was done and it was to fix some compatibility with hardware that I don't have. So I did it at a time I would not do anything.
Since then, the fan began to work at full speed almost permanently, sometimes it slows down to normal operation (really normal, increase rotation when the device heats up, slow down to 2k rpm when it is cold).
I have formated the HD twice, because I tought that had done something wrong, but the problem persisted, so I used the hardware diagnostics and found two error numbers, one for the fast run:
4SNS/1/40000001:TN1D - - 110.00
And another for the extensive test:
4SNS/1/40000001:TN1D - - 1.000
I searched these numbers but the results are not good nor precise, peaple said it's related to thermal detector or the logic board permanently damaged.
My current SMC version (after the update) is 1.60f6
I don't know the old version of SMC.
I installed iStat PRO widget, from where I can see that all thermometers are operating normally (these must be the source of the control of the fan) and the fan running at 6,200 rpm.
I even tried to install Fan Control system pref component, but it can only increase the commanded speed of the fan at any time, never decrease.
I also tried to reset SMC as said in http://support.apple.com/kb/HT3964 , sugested in https://discussions.apple.com/thread/1306035
Is there a way to roll back to the old SMC version?
Or to install some program to overwrite the wrong control?
Thank you.

you need to bring it to an Apple store or AASP to have it properly diagnosed. Only Apple certified technicians have access to what those diagnostic codes mean.

Powerbook G4 12" Fans running on High after update

Hi all. I just finished a pushed update (and I apologize, as I do not even remember what was updated), but as soon as the update finished and the software installed, the fans started (and continue after several shutdowns) to run at high speed. Is there a way to see what was updated and how to remove that update as it is obviously causing some serious issues with my computer. Thanks very much!

HI Bob,
For fan issues, try resetting the PMU. http://support.apple.com/kb/HT1431
Hopefully that will help.....

IMac is much too loud after updating to 10.4.9

Hello!
I just installed the 10.4.9 Update on my Intel iMac. Right after reboot I launched iTunes and noticed that the sound volume of the Mac had been increased by far!
What has been my normal listening volume (50%) is now really loud, normal volume seems to be 1 or 2 boxes on the scale you see when changing the volume.
This is really annoying as you cannot listen to quiet music any more without changing the volume directly in iTunes (what doesn't work with the remote). Furthermore this would mean to change the volume in any program manually. I think that is not the way an Apple system should work...
iMac CoreDuo 20" Mac OS X (10.4.9)

Sorry for that. I should have had a closer look first, though I did not find a topic concerning this special problem.
Well, I hope there is some update coming up from Apple, for I don't see any practical solution to this.

My MAC fan runs extremely loud when I use Safari. What can I do to fix it?

When using safari my Mac gets extremely loud. No flash content, no video. It can be sitting there untouched just with safari open and out of no where the fans kick in and loud. What can I do to solve this issue?

To remove a forgotten Restrictions passcode you will need to either...
1) Restore the Device as New... See Section 6 here...
http://support.apple.com/kb/HT4137
OR...
2) From a Backup created Before the Restrictions Code was set....

My iMac's fan runs quite loudly.

I only got the computer yesterday from Apple, but it was refurbished. It's an iMac 21" 2.7 1TB.

When you say that the 'fan runs quite loudly' do you mean that the fan is making an unusual noise such as a buzzing or clicking sound, or do you mean that the fans sound like they are running at full speed?
If the fan is making a buzzing or ticking noise then that could indicate that something is touching or rubbing against the fan. If you just purchased the iMac then I would contact Apple to arrange for a replacement.
If the fans sound like they are running too fast then it could simply need an SMC reset. To do this, power down the iMac and then disconnect the power cord for ~15 seconds. After 15 seconds plug in the power cord while making sure you don't press the power button. Here's an article that provides additional information on this condition and why it occurs.

Satellite A300D - Fan running very loud and notebook is getting very hot

I was wondering if anybody could point me in the right direction as what to do with the overheating problem i currently have with my A300D. I have had the laptop for under a year so it is still under warrenty but i am not sure where to go or what to do in order to repair it.
The problem: Around two months ago I noticed the fan running very loud and also the laptop becoming very hot. Now it runs so hot the laptop switches itself off completly. The heat being fanned out of the laptop is so hot! burns your my infact.
Has any one any advice they could offer me.
Thanks
James

Hi James
You wrote that you have the notebook under a year so my questions is did you already clean it?
The notebook should be cleaned every 3-4 months and I do this every 3 months. Every time I do it Im wondering how much dust comes out and after this procedure the notebook is a lot of cooler.
Here is an interesting Toshiba article about this:

Compressed air spray is really useful and you should check it yourself!!! ;)

Why is my fan running so loud?

I purchased my 13" macbook pro about 2-3 weeks ago, But have noticed just recently my fan running quiet loud and constantly. I have done two smc resets that didn't change anything, checked my activity monitor to find nothing wrong, and checked my exhaust rpm and temperatures which were perfectly normal. Does anyone have any other information that would help me fix this frustrating problem?

You are still under warranty. Call Apple Care. Make sure you get a case number as all repairs have an additional 90 days of warranty.
#1 - You have 14 days from the date of purchase to return your computer with no questions asked.
#2 - You have 90 days of FREE phone tech support.
#3 - You have the standard one year Apple warranty.
#4 - If you've purchased an AppleCare Protection Plan, your warranty last for 3 years. You can obtain AppleCare anytime up to the first year of the purchase of your computer.
Take FULL advantage of your warranty. Posting on a message board should be done as a last resort and if you are out of warranty or Apple Care has expired.

CPU fan running full speed after 15 minutes

My 3 month old iMac 24" has just started having fan problems.
Before I went away on a training course, it was working fine. Left it switched off at the outlet for 3 days, now the CPU fan runs full speed after the iMac has been switched on for 15 to 20 minutes.
CPU temp is 24C, CPU heatsink is 28C. Ambient is 17C. CPU fan is 3600rpm. Other fans are normal.
CPU usage is less that 10%. Only Safari is running.
I've tried resetting the SMC - left all plugs disconnected for 15 minutes, reconnected mains power for 15 minutes, reconnected USB, then switched on.
Still the same - OK for 15 minutes, then CPU fan runs full speed.
Anything else that I can try?

I tried again, following your instructions exactly. It seemed to work, running normally for about an hour.
I left all the USB devices unplugged, except for the keyboard and mouse.
I then shut the iMac down, but left the mains power turned on at the wall. When I switched it on again 2 hours later, all was OK for 15 minutes, then the CPU fan ran at full speed.
Shutting down for a few seconds fixes it for another 15 minutes.
I'm wondering if it's a software problem, although I haven't loaded any apps recently, apart from a few monitoring programs since this problem appeared.
Last night I left it running the extended hardware test for a couple of hours, and the fans were fine.
One thing that I noticed yesterday was that the "GPU" temperature readings in iStat were all missing (just "-" displayed) for a couple of seconds when I clicked on Dashboard. Is there a way to keep iStat open while I'm using the iMac?
I think I'll try booting XP and see what happens.

Mac audio TOO LOUD after rebooting Mac

After rebooting a PowerMac G4/500 (AGP) with Mac OS X 10.4.6 sounds too loud (as if it was at top highest volume) when playing audio files, even though the audio setting (keyboard audio keys) is set to only one to three points. Just clicking such keyboard audio buttons (to lower or even increase it) fixes it and the audio returns to its correct volume. What is going on? This is driving me nuts!
Thanks.

Justin,
Thanks. I have done as indicated, shut down and booted, yet the issue persists. For instance, if I go to iTunes and play a song, it plays very loud, yet the audio is set at a single point. I can see it clicking the keyboard audio keys. As said, once I click any of such keys (increase or reduce volume any amount) the audio returns to its normal volume until the next time that I boot the Mac. This is a 100% consistent issue. Weird.

Fan is too loud

normally when i start my mbp it is normally quiet. Then one day all of a sudden the fan just got really loud. I dont know what happened or why it is so loud and i only have 2 applications open. SO can someone help me thanks

One day about a week after I got my new MacBook, I shut it down and closed the lid, then noticed the fan was somewhat loud. I'd hardly ever heard the fan before, but I didn't think too much about it. I figured it was just warmer than usual and the fan would run for a bit then shut off. I put it in a bag and a few hours later when I took it out it would not start up. Turned out the battery was run down. I assume the fan had kept on running until it depleted the battery. It's only happened that once, but I'll be paying attention from now on when I shut it down to make sure the fan isn't still running. I guess if I had too, I would just pop the battery out.
Make sure you have installed the latest firmware updates for your Macbook. They update the fan controller.
