Fan buzzing noise at 6000 rpm.. Sound worst when tilted on any axis...

My macbook been overheated since the Snow Leopard upgrade but what really anoy me the most is that the fan make a buzzing sound over 6000 rpm and when I pick up the MBA is tilt in any axis it make a noise like a fly is right next to your ear and it also feel like the fan is loose or somthing. Is that fan sound normal for those who got a macbook pro. Try tilting the laptop a little and does it make a weird sound? I keep thinking is a defective fan or something is loose that relate to the fan.
Does this happen with your guys macbook air? Is this normale of should I bring it in and see if I can get my fan replace.
I can barely hear it at 2000 rpm but at 6000 is really anoying to work with the computer for me...

I would get it check out. It might be the blase hitting or a motor bearing.

  • HELP ME !!!! My MBP fans are stuck on 6000 rpm

    I recently cleaned the right fan on mbp because it was making a grinding noise . I then ran smc fan control to make sure that my fans were running well , now everytime i switch on my mbp the fans rev up to 6000 rpm and stay even if no programs are open. My temps are averaging around 35 celcious . I have tried everything , smc reset , pram reset , osx complete reinstalation and also tried to do a firmware restoration . None of these things have worked . Please help me

    Have you tried running the Apple Hardware test? I'm wondering if a thermal sensor may have become dislodged or unplugged, as that would also cause the fans to run all out.
    Also, have you checked in Activity Monitor to be sure you don't have some hung up process hogging the CPU and causing the fans to run all out? Be sure to select "CPU" on the bottom bar and "All Processes" on the top.
    Good luck!

  • Hard Drive fan suddenly running at 6000 rpm

    Hi, I have a 2009 20" iMac, 2.66GHz Intel Core Due running 10.5.8. I have iStats Pro and SmcFanControl installed.
    Randomly, my HD fan goes from 1099 to 6000. I can fix it by putting my Mac to sleep, wait for 10 seconds, and then proceed, The HD fan speed goes from 6000 down to 1099 and it will stay there. Sometimes this hapens a second or 3rd time. Every time I put the machine to sleep. And every time it "fixes" it. After 3 to 4 times going to sleep, the problem weems to be permanently solved and the "vacuum cleaner" does NOT turn on anymore. Obviously, this is highly annoying and not a solution.
    Is there any real solution to this problem? I bought this machine in July 2009, no Apple Care because I have had luck with Apple products in general (my iMac DV from 1999 still runs...). It seems as if my luck has run out.
    I scoured the boards but nobody seems to really know what is going on. I read about temp sensors and logic boards. Seems dramatic to me. Is this something I can fix myself?
    Has Apple recognized this as a real problem??? Because it IS! I am very disappointed. You do not expect this from a newer machine.
    Thanks for your help.

    First off smcFanControl is not going to fix the problem, it can only run the fans faster and not slower than the iMac's System Management Controller is telling them to run.
    It sounds as if you have either 1 of 3 problems:
    1. you need to reset the iMac's SMC.
    2. the Hard Drive is actually over heating for some reason.
    3. you have a faulty HD temperature sensor or bad connection (wire) between the sensor and logic-board.
    I would do the following:
    1. disable or uninstall smcFancontrol
    2. reset the iMac's System Management Controller
    as per >  http://support.apple.com/kb/HT3964
    1. Shut down the computer.
    2. Unplug the computer's power cord.
    3. Press and hold the power button for 5 seconds.
    4. Release the power button.
    5. Attach the computers power cable.
    6. Press the power button to turn on the computer.
    3. then if and when the HD fan acts up (ramps to 6000rpm) run the extended Apple Hardware Test
    as per > http://support.apple.com/kb/HT1509
    4. use the iStat Pro widget to check the sensor readings for the Hard Drive and Hard Drive bay when it acts up.

  • Fan buzzing noise

    Hello, my 13 inch late 2011 (Lion 10.7.5) MBP has started to make a buzzing noise when the fan is running. Its sort of a low E and a constant buzz, no static, so I dont think it has to be cleaned. When the fan gets louder and faster it drowns out the buzzing, so that also makes me worried.
    Oh, and if needed, I downloaded a Fan Control pref pane in January.
    I also just deleted some junk and cleaned up my computer.
    Thanks,
    Narmo

  • Fans always running at 6000 RPM.

    I have had this problem since my friend gave me his old macbook pro. The fans are very loud and running very fast. First I thought dust might be stuck inside but I checked and nothing was there. Nevertheless I cleaned it. When I powered on my macbook it was still very loud so I checked with SMCFanControl and it was still running at 6000 RPM. I have tried resetting PRAM and the SMC without any success. Also software like SMCFanControl and iCyclone won't let me change the speed even though the CPU is at 40C most of the time. I don't really want to take it for repair at the apple store because they will probably charge me a fortune. It is a MacBook Pro Late 2006 model. Thank You.

    Same situation here - the only update: it started to happen after I replaced the palmrest, screen assembly and installed SSD Intel X25M drive. First, at startup fans are quiet, and then slowly going to higher speeds. Since I did upgrade everything at the same time I did not catch what was the source of this issue. First I blaimed SSD since it's not getting any warmer (as oppose to standard SATA drive) and that might have confused the Mac's fan control. The other thought was the SSDs have a different SMART reporting method... Well, all kinds of resets (SMC and PRAM) did not help, neither utilities like smcFan Control and others. BTW, smcFan control shows temps from 35C-37C and 5200-5500 RPM. Fans are blowing a cool air, no signs of overheating at all.
    Bad temp sensors?
    Any thoughts?

  • Brand new Macbook Pro -Fans on constantly at 6000 rpm. Very Noisy. Broken ?

    Just bought a macbook pro today. The fans on it are constantly on ... all of them, spinning at 6000rpm no matter what the machine is doing. It sounds like a hurricane. I have tried to reset the SMC (no effect), update the firmware and EFI (refuses .. saying this update is not required), reset the pram (no effect) and resinstall OSX (no effect). The temp of the machine is only 34 degrees C (no doubt due to the fans being on constantly).
    Its like this on battery / AC / and even on better energy saving settings !
    Whilst the machine works, it is unusable. It sounds like a vacuum cleaner.
    There are utilities out there (smcfancontrol) that let you set the minimum speed for your fans but not the maximum speed... ! Typical. !
    Any suggestions... otherwise I will be returning this machine to a John Lewis branch tomorrow and asking for a refund (faulty machine). I suspect the thermo monitor is borked.
    ??? Thanks for any suggestions

    I have exactly the same problem - right down to the last of your words!
    I have had discussions with Apple Care but, sadly for me, I will have to have them look at it in my local apple store and I have no idea how long it will take.
    All I can say is that the noise is terrible - when you shut it down its like lovely peace and quiet! Imagine me in the library at Uni - I sound like the cleaning person!
    Good luck with your return and I will see what happens once I can actually get hold of someone from Apple Store!

  • Why do both fans always run at 6000 RPM

    I have a 17" MB Pro which spins both fans at 6k ALL the time (when it's on), even though the machine is not running hot.
    They go off properly when it's in sleep mode, but after wakeup or restart the fan speed will start out slow (and inaudible), then slowly increase until after a minute or so both are running at max speed.
    CPU heatsink temps are in the 93 - 95 degree (F) range.
    I have reset SMC, deleted com.apple.PowerManagement.plist file, same behavior.
    Any thoughts on this? The noise is getting to me.......

    I have just begun to have the same problem as of last night, also with a 17" MBP. I spent time on the phone with an AppleCare rep, but the fans stopped on their own after a reboot into Windows and then back into Mac OSX. As of right now, they've started again.
    As in the case of the first poster, my computer is not running hot, nor is any process taking up a lot of CPU cycles. This is really perturbing me.

  • My fans are running at 6000+ RPM all the time - new MBA 1.86

    Run the extended version of the Apple Hardware Test that you'll find on one of the DVDs that were shipped with your MBP. I expect AHT will report a SNS error, indicating that one of the temperature sensors in your machine has failed. When a temp sensor fails, the fan or fans usually run at top speed all the time as a precaution, in case the machine is overheating but the bad sensor is failing to report it.

  • I have an i pod and am having problems with sound. When I watch any video on the device with headphones the music is always too loud for the voice meaning i can't hear what is being said. This problem is accompanied with a buzz in some parts of the music.

    When watching a video with my headphones the volume of speech seams very low even when i adjust volume. The speech also tends to make a humming sound in places. When I listen to music humming is sometimes transmitted, but the volume level is normal. The problem is that when the video is playing i can only hear music and humming with the voice too quiet to hear properly. How can I make both volumes balanced? Also. This happens in all music videos.

    - Try cleaning out/blowing out the headphone jack. Try inserting/removing the plug a dozen times or so.
    - Reset the iPod. Nothing will be lost
    Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Reset all settings
    Go to Settings > General > Reset and tap Reset All Settings.
    All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
    - Restore from backup
    - Restore to factory settings/new iPod.
    - Make an appointment at the Genius Bar of an Apple store. Seems you have a bad headphone jack.

  • Fan speed always 6000 rpm

    Hi!
    I got early 2008 MBP , and both fan speed is around 6000 rpm. They work such way all time.  GPU temp in fan control is 0 , other temp is ok. In program (Temperature monitor) i can see a temp of Graphic Processor Temperature Diod, is it a temp of gpu? I try to run hardware test, but i haven't got install DVD and holding D when starts doesn't help.

    If your GPU temperature is 0, that suggests a problem.  It may be that the fan controls have set to a default level and thus the 6000 rpm fan speeds.  I think that you will have to take it to a repair facility for evaluation and repair.
    Ciao.

  • Will fans running at 6000 rpm hurt my macbook pro?

    Whenever I run certain programs the fans will run at 6000 rpm after 20 mins or so.  The actual temp of the computer will reach 80C max but the fans seem to be working very hard. Will this harm my computer?

    Yes and no. The fans are spinning at that speed to try and keep the system cool. That is normal. But the excess heat being built up from that program will cause parts to ware faster than less heat.
    Will it cause the system to fail sooner than later? Maybe then maybe not. Each computer is different, even of the same exact model. Some last a long time, other don't no matter how they are ran or treated.

  • Fans going at 6000 rpm with little cpu usage--computer too hot?

    Hi,
    I am not sure what normal temperatures are for my computer, but often the fans are running at 6000 rpm when the computer doesn't have all that much going on. When I am trying do anything actually demanding, the fans are running non-stop. I've also noticed that things have just been running rather slowly, with lags in mouseclicks and typing. I am not sure if these are related, or why the computer might be working so hard to complete simple tasks. Here is a picture of iStatPro showing what's going on--CPU is 95% idle and the fans are at 6000 rpm. Does anyone know if the temperatures shown are normal or what I can do to improve the situation?
    Thanks!
    Laura

  • Horrible buzzing noise whilst on charge

    Hi all...not sure if anyone has had the same problem but when my Mac is plugged into charge and I have audio or video playing I have this awful buzzing noise in the back ground but when unplugged the audio is perfect - maybe there is some kind of electrical interference happening but it is getting a bit serious as I am a musician and I need total clarity with my recordings. Has anyone had this before? Please help?
    (Was thinking maybe a shielding issue or something)
    Thanks in advance!

    Are you using a third party power supply? I've heard some of these cause hum / buzzing. If you look at the comments here for example:

  • Macbook Fan Noise at Low RPMs

    My Macbook makes an annoying buzzing noise when the fan is running at low rpms. It sounds almost like a motor running and is very irregular. If I use smc fan control to up the rpms to near 3000 this noise stops and becomes the usual noise for a fan running at higher rpms.
    Is my fan broken or put in incorrectly? Is there anything I can do?

    To add to Michael's statement. There is a 14 day window for returns. If you just got it return it and get a different one.
