MacBook 13" Air 2012 Fan Runs Incessantly

Why does my new 2012 MBA fan run constantly when docked to Thunderbolt display, even when asleep? If this is unfixable, I may need to return this otherwise beautiful machine

turn off bluetooth sharing.

You should contact AppleCare as soon as possible.
MBP is in warranty for 1 year from the date of purchase.
AppleCare: 1-800-275-2273.
Standard troubleshooting step for these kinds of issues is to reset SMC.

My MacBook Pro 13" (2012) is running Windows 7 on Bootcamp and there is an issue with the headset I'm using.

My MacBook Pro 13" (2012) is running Windows 7 on Bootcamp and there is an issue with the headset I'm using. I use a cheap Logitech Stereo Headset H130, but since there is only on audio plugin on the computer, I purchased a 3.5 mm 4-pin smartphone audio adapter thingy. That allowed me to put both my the sound coming to my headset & the microphone on my headset onto one wire. Everything worked wonderfully when running the Mac OS since they probably have support for that kind of stuff. The problem is though that once I try to use the same method in Windows 7, the OS doesn't recognize my headset microphone at all, but, instead when recording my voice decides to use the built-in mac microphone. Using this adapter still allows me to hear from my headset, but not use the microphone and that becomes a problem. It might be so that Windows 7 doesn't have support\drivers for that... How should I continue from here on out? Any advice?

From what I have read from others on here you may be out of luck. You would need the appropriate Windows drivers for the Cirrus chip in the Mac and no one has been able to successfully locate them. Apple wouldn't support this since Windows is an optional install.
Sorry to bring the bad news.

If you fan is not working, then you will have to bring the MBA to a repair facility.
You may try a SMC reset:

That might restore the fan function.

2010 MacBook White is unstable, fan runs all the time and wifi adapter randomly quits

I have a 2010 white MacBook running OSX 10.8.2 and last week rather randomly it became unstable. The fan runs nearly constantly and intermittently it does not recognize the WiFi adpater on start-up and has to be rebooted. Also sometimes after 15-20 minutes of use internet connection is lost. The WiFi adpater is still connected to the LAN, and recognizes other devices on my network, but cannot connect to any local device or the internet (Mail, Safari, or Chrome).
Any ideas?

This sort of helped.   Here is what happened:
     Upon the first boot after resetting the SMC, the MacBook indicated there was "no WiFi hardware installed."
     Shut down the MacBook and waited 15 seconds then started - it recognized the WiFi hardware and indicated a connection to my local network, however none of the local devices could be found and the internet was not connected.
     Restarted the MacBook to the same results as the previuos shut down/start up.
     Shut down the MacBook and waited for 15-30 seconds. Upon pressing the power button only the indicator LED on the lower right side of the body illuminated solid and nothing else happened.
     I had to then press and hold the power button for 3-5 seconds for the LED to go out.
     I pressed the power button and the MacBook started (very slowly). I gave it a few moments after the desktop appeared and the bars appropriately populated (WiFi indicator on the top bar looking good). Internet and local devices connected and no fan . . . yet.
My confidence is low, it's only be about 5 minutes, but will post again with an update . . .

Macbook pro 13' 2012 fan problem? (high cpu temp)

my macbook gets cpu temp at 98C and then the fan starts raising speed from the default rpm(2000rpm).
with heavy cpu usage and cpu temp at 93-100C, tha fan waits about 2-5 minutes and then kicks in and increase the rpm( the higher rpm i saw was 4000rpm at 101C cpu temp). all the other time the fan speed is between 1995-2004rpm.
Is this normal?
I've already tried SMC and PRAM reset and clean OSX installation.

thank you for your answer.
But is it normal for the fan to wait so long 2-5 minutes and then start raising the rpm?
I expected that the rpm will go up simultaneously with the Cpu temp. Like if the Cpu starts increasing temp (about 70-80C) the fan will kick in...
I know from a friend with a Macbook retina that his fans keep spinning at 3000-4000rpm and always keep the Cpu temp close to 60C. I know that the architecture is diferent but the cooling logic should remain the same. right?

Brand New MacBook Air 2012 Fan Always On with Only a Few Programs Open!

Got this awesome machine a few days ago. Everything is perfect except the fact that the fans are on 24/7! I have nearly no applications running and I've cheked the activity monitor and nearly everything is at 0% and the programs that aren't are around 5% (or less). I've got a protective case on the computer and I've taken it off and tested the situation out and without the cover the MacBook Air still runs the fans at full speed.
As I'm typing this, the fans are just blasting. I never new a computer fan could get so annoying!

Oh snap. FahCore_a4 user: nobody CPU: nearly 400%!....what on earth is this. I did a Google search and it's suppose to relate to a Windows thing....
http://folding.stanford.edu/English/WinGuide
Supposedly relates to a "Share your computer power for research". So this is what I get for doing charity? How rude!

Unresponsive MacBook Air with fan running and keyboard lights.

This is a weird one: I opened my MBA today to find it dead, ie no lights or sounds. I initially thought the battery was empty so I hooked it up to the power adapter. No light on the plug. After realising that the power adapter was ok I did an SMC reset, which started the fan and the keyboard lights. Other than this there is no sign of life. I am unable to start or stop the machine and there is no effect when using the power button (Ctr-Cmnd-Pwr).
Any bright ideas out there?
Many thanks in advance...

You should also ask this in the MacBook Air forum. This is the forum for the white and black plastic MacBooks that were discontinued in 2010. You should also post this question there to increase your chances of getting an answer.

My Macbook Pro Retina 2012 is running very slow and gives me frequent speed problems.

So, I've noticed it happen gradually for about a year now. It started with just minor but not significant delays in opening up programs, but I didn't mind it because the computer was still fast compared to a PC, which is what I used to use before this Macbook. I got this macbook in 2012, and luckily I still have a warranty, but it'll close soon.
Right now, some problems include:
1)
2) Shutting down and turning on the computer is slow (sorry no picture on this one). When I first bought this mac, and until about a year ago, whenever I turn it on/off it would do it instantly. But now, there is a bit of a delay when turning off. The screen seems to just freeze at a certain frame, stays that way for a few seconds (longer when turning it off right after playing a game or two-- don't worry they're compatible with Mac OS), and then shuts off. And when it's frozen at that frame time, you can still see the background materials because they're only faded away. You know what I'm talking about-- Macbook turns out when turning off and then shuts down. So, much of the screen is white, but you can still see the screen prior to the shut down faded.
3) Internet is running extremely slow. When I check my speed at speedtest.net, I get around 47 mbps on bad days and 53-ish on good days (download speed)

Resetting computer to factory conditions doesn't work, time-machine didn't work, and clearing more storage space didn't work either. I would like to get this problem fixed before my warranty runs out. Thanks for reading and any sort of help will be appreciated!

Do you know of any specific tasks or situations that cause it to perform poorly? If so, make a note of those and demonstrate them for Apple. Do NOT, under any circumstances, restart the machine. You want it at its worst when you take it in. If you try to do any of those magic resets, it may just reset things just long enough for Apple to proclaim it healthy. If Apple does that anyway, then there are plenty of opportunities to try those things later after your warranty has expired.
I wish I knew exactly when it does this, but it doesn't always happen. It sometimes does, and sometimes doesn't. I thought about this, too. But the problem is that it's really hard to catch a time or figure out what causes these symptoms to occur. I haven't taken it to Apple because I thought it'll just be a waste of time because they'll probably say that it's healthy so they don't have to put any money/effort to try and fix it...

Macbook Pro 2008. Fans run on high. AHT shows not issue

Have an older macbook pro thats been sitting on the shelf a while. I have a new battery on order so I am powering it solely off AC right now but when I went to start it nothing happened. Did some research and found that holding the power button while disconnecting and then reconnecting power might bring it back....and it did. When it started up it looks like its flashing the SMC and the fans kicked up to max and stayed there. I have run the AHT and everything passes just fine so I downloaded fan control. It shows 0 RPM -0 Celsius Temp, left fan -1,073,7 RPM and right fan -1,607,0 RPM. It looks like the sensors are bad but AHT found not issues (even on the deep scan) so i'm wondering what I should try next? Thanks for any help i've been searching for days on this.
OS 10.10 - same problem on 10.6.8
15" Early 2008

Bring the MBP to an Apple store genius bar and have the technicians check it out. Their diagnostic tools are superior to the AHT. The evaluation will be FREE.
Ciao.

Macbook Pro 13" 2012 Fan

Hey,
I'm new to owning a Mac! Last week I bought my first Mac in-store and had no problems with it, until today.
Today I noticed that the fan is rather loud especially compared to people who have the same model (the base 13" non-retina). I must admit I'm quite surprised as my windows laptop which is considerably older isn't much louder. I'd like to take it into store to get it checked out but this isn't very easy as I live over three and half hours away from one.
Therefore I'd like to ask is this normal? And if not what are my best options?
Thank you!

Macs set the fan speed based on measured temperatures. If your fan is loud, it indicates your Mac is working hard. If you think it is loud at idle, something is wrong. This article may help:

Macbook pro mid-2012 13" has very slow disk access

Until 3 days ago my macbook pro mid-2012 13" running OX 10.8.3 was running fine. Then, it showed very slow response anytime it had to access the hard disk. After doing the usual checks and disk first aid repairs to no avail, I booted from my external disk with an older copy of my hard disk and everything then worked as normal, except when I accessed the internal hard disk, then it crawled once again (spinning beach ball, took many seconds just to open a finder window and then several minutes to display the contents). I ran the Apple Hardware Tests and it said everything was fine, even though it tooks several minutes before the test would actually start. I also ran the program BlackMagic Speed Disk to find out if the disk was having transfer speed problems and it showed a respectible transfer rate (60MB/s), not great but not like the 0.3MB/s I was getting when I tried to back up the internal disk. I was using Carbon Copy Cloner to try to back up the internal disk but had to give up since at 0.3MB/s, it would take days to back up the 250GB on the disk. I found on the web that using "restore" in Disk Utility, I could do a disk copy without the file by file copy which allowed me to back up my disk in "only" 6 hours. Booting from my newly made copy on an external disk worked fine and ran at nearly normal speed (slightly slower since it was an external disk running through USB2). As a final attempt to prove this was a disk problem, I erased the internal disk and reinstalled OSX 10.8. I am still waiting for this install to finish, it has been 5 hours although the progress bar said it should be done in 20 minutes. This was fairly convincing evidence that it is not a software or settings problem. However, all my web searches could find no other case of a problem like mine. I presume I have a failed hard disk but as all the diagnostic programs say it is working fine, I was hesitating to bring it in without hard diagnostic evidence. If anyone knows what might be the problem, it would be much appreciated to hear from you.

It should not take 5 hours to install Mac OS X. There is something wrong with the disk. Try reformatting where you do a wipe of the drive (an select the option to write zeros which will remap bad sectors). Then try to install MAc OS X.
I got this information from here:
http://reviews.cnet.com/8301-13727_7-20064489-263.html
Back up your data.
Use Time Machine or a system cloning utility to create a full and restorable backup of your data. If you suspect bad blocks, then when cloning you might consider not using a "block-level" copy process, since this will likely run into problems.
Boot to the utilities DVD.
If you have a boot DVD for a tool like Drive Genius or another drive utility, then boot to that; if not, use your OS X installation DVD (once you select your language, open Disk Utility from the Utilities menu).
Format the drive.
Using your selected utility, format the drive and check for bad blocks. If you are using Disk Utility, click the Erase tab, click the Options button, and then select the option to write zeros to the disk (you do not need to do multipass erase options, as this will provide no additional benefit for managing bad blocks). Writing to zeros may take a couple of hours depending on the size of the drive, but when done the drive will have remapped any blocks that were not reliably read.
Restore the OS installation.
If you have used Time Machine to create your backup, boot to your OS X installation DVD (if you are not using Disk Utility) and use the option in the Utilities menu to restore from backup. Attach your Time Machine drive and then proceed with the restoration, selecting the newest backup as the one to restore to your system. If you have used a system cloning tool, then attach the cloned drive and boot off of it (hold the Option key at start-up to select it from the boot menu). When you are booted to the cloned drive, run your cloning utility to copy the installation back to the computer's main boot drive.An optional approach here is to perform a full reinstallation of the OS from your installation DVD, and then migrate your data, applications, and settings from either the clone or the Time Machine backups using Apple's Migration Assistant.
