Fan loud and laptop hop

MacPro running hot and noisy since upgrading to osx 10.8. Funambol-sync using 42% cpu. Annoying - pls help

Right-click the installer and choose "Open" from there, and then confirm you want to continue installing. Alternatively, go to the Security system preferences and temporarily set the option to "Allow apps downloaded from" to the "Anywhere" setting. This should allow the program to run.

  • Fan loud and hot

    My Mac pro started running loud and hot after upgrading to osx 10.8.4 and moving to icloud. Tried suggestions posted w/no luck. Pls help as no longer want to use it!

    Open Activity Monitor, select All Processes instead of My Processes, then order the processes by CPU. Post an image of what processes are using the most CPU and how much. Also, do an SMC reset.

  • 21" Imac Fan Loud and Random

    Hi there,
    After trawling these forums and others, my problem has driven me to the point where I thought id post my own thread on here.
    I have had my 21" Imac for about 5 or 6 months. Up until about a month ago it has worked perfectly, until one day, whilst Idle, a fan inside kicked in randomly. Ill detail the circumstances and information here:
    Fan, which is blowing air out of the top slit on the left hand side of the imac has tendancy to turn on randomly
    When this happens it is VERY loud (for a computer fan)
    When this happens it continues until I put the imac to sleep, or shutdown/restart, which buys me a bit of time
    I have checked temprature readings and highest at these times have been about 60-70 deg celcius at the GPU, nothing ever higher than that
    Ambient temp never been more than about 25/26.
    This happens whether idle, or if im using a relatively heavy application all the same. Most of the time when it kicks in ive checked the CPU usage, which has been very low (10% or so) with just a few chrome tabs open.
    I have tried reseting the SMC/SMU many times (switching off, unplug for over 15 secs, switch on) (and method where you hold power button for 5 secs before you plug it back in) The fact that this has not worked is very frustrating as most of the other problems on the forums seem to be resolved by this.
    I have reset the PRAM twice.
    I ran the imac hardware diagnostics (hold D at startup) last night, one quick test and one extended test, showed no problems.
    The funny thing is that i experienced the same problem during the test. I am sure it was not part of the test as it continued well after the duration of it.
    This problem has really started to get on my nerves now, as the Imac is a core part of Sound engineering and music production related work and study - as you can imagine the noise is a real bane of this.
    Any help will be greatly appreciated guys, cheers.
    Thanks in advance.

    Hi Vance
    I feel your pain mate. However, having said that, here is the situation since my last post-
    The problem persisted all the way up to early september when i left home for uni.
    Since, it hasnt reoccured once. There are two reasons I can think of for this:
    A) packaging up the imac and moving it a few hundred miles in the car may have knocked something (e.g. A loose sensor connection) back into place. I can imagine that this would therefore mean the problem may appear in the future, when relocated again.
    B) i have a basement room at uni which provides a very stable, relatively cold temptature (thank god with no damp, an ideal hideout) at home the room used to get ALOT hotter (thick carpet, and more heat from larger studio monitors/subwoofer etc) worth saying though this would still happen when cold at home. Maybe it is environment related?
    Maybe also worth mentioning my old laptop always used to completely crash out on the basis of the graphics card overheating whilst at home, but ever few weeks where i would live elsewhere for a while it would always be fine. Very odd.
    Thats probably the most i can suggest, and do let me know if you find a solution or supernatural fix to this problem. This drove me bloody nuts for ages and no forum threads on the net directly tackled this particular circumstance as far as i am aware.
    Im sure anybody else in our boots would much appreciate seeing this thread rather than be corroded by the problem for so long whilst taking thier kit to the apple store isnt convenient.

  • X300: Annoying fan (loud and almost constanly running)

    Hello,
    after having my X300 for about 3 weeks now there are a few things that I'm not very happy with. The most annoying part in this laptop is definitly the fan!
    After poweron it takes only a few minutes till the fan is spinning at Level 1 (2000 RPM - that's ok, because it's almost impossible to hear).
    But after some more minutes (of almost no load) the fan goes to level 2 (about 5000 RPM).
    As a result, temperatures fall but the fan doesn't go off. If I produce some more heat (OpenGL Game) the fan will even speed up more
    (level 5, ~ 5700 RPM) but it won't go down later.
    Here's a little gnuplot of all I said:
     http://0je.de/pub/temp/x300_fan_01.png
    Some information about my system:
     Linux 2.6.25
     ThinkPad BIOS 7TET25WW (1.02 ), EC 7THT15WW-1.00c
    And some more: Why are there no fan speeds between level 1 and 2? Theres a difference of about 3000 RPM there ... (impossible to hear vs.
    quite annoying).

    I complained about the noise and the missing control of fan speed using the Lenovo-Support-Form. After some days I got a flat answer telling me that software-support is only available till 30 days after purchase.

    Are they unable to read (I also included a link to this thread) or are they just unwilling to fix the problem?
    Maybe everyone else should use that support-form, too. Here we go:

  • My MacBook Pro (Early 2011) keeps freezing, the fan becomes extremely loud and the laptop gets very hot, what can I do?

    Hi there,
    I would be grateful if any one could help me. I purchased my MacBook Pro  13 Inch in August 2011, it was the "Early 2011" version, which was shipped with Lion (I have now upgraded it to Mountain Lion last year).
    Up until a few weeks ago, it was running fine. But recently my MacBook keeps freezing (A circular rainbow appears on the cursor), slowing down, the fan gets very loud and I often have to restart the whole machine. This usually happens when I'm running programs such as Safari, Preview or Microsoft Word
    I only use my MacBook for university work so I only have Microsoft Office and iWork installed, nothing else. I've only used 19gb out of the 320gb available. I've also reseted my MacBook to its factory settings but that hasn't fixed the problem.
    I've checked my AppleCare status and it says:
    Repairs and Service Coverage: Active
    Your product is covered for eligible hardware repairs and service under a custom agreement.
    For more information about your coverage, please contact us.
    Estimated Expiration Date: 24 August 2014
    I was wondering if anyone had any suggestions to how I can resolve these problems, as it is stopping me from doing my work?
    Many thanks.

    Call Apple and make a appointment, backup your use data off the machine to a external drive.
    Don't bother with TimeMachine if it asks, too long and likley be corrupted and unable to restore, just drag and drop your Users folder to the external drive.

  • Why are my fans so loud and my macbook pro so hot?

    I have a 15" MacBook Pro.  I've had it since a little bit before Christmas and the fan has always been so loud and the laptop itself, as well as the charger, tend to get VERY hot VERY quickly.  I'm keeping it elevated so it's not being suffocated but it doesn't seem to help.  I've already checked Activity Monitor and nothing is running up my CPU very much and I'm out of options.  Any help is appreciated!! It's driving me crazy!!

    Those are very, very high temperatures and very high fan speeds just trying to cool things down.
    Now - which applications or processes are turning up the heat? Open Activity Monitor (Applications>Utilities) and select "All Processes" and sort by CPU %:
    Then post your screenshot (http://support.apple.com/kb/PH4391) using the little camera icon in the composition bar at the top of your reply.

  • Fan suddenly starts up and laptop starts lagging

    I recently purchased a refurbished 13' Macbook Air. It has been working perfectly until now. I stream shows on my laptop and suddenly the fan starts up really loudly and my laptop freezes and lags. It isnt overheating. I've checked the CPU. I also occasionally get volume issues where I have to restart the laptop to get it working again. Any suggestions?

    Reset SMC.     http://support.apple.com/kb/HT3964

  • After browsing websites, the fans get louder and louder, no internet.

    Hi,
    With my 2011 Macbook Pro 15inch, I have found that browsing some websites causes the fans to spin up very loud and the internet to drop.
    Websites won't load etc. Even after reconnecting to my wireless network. The only thing that seems to fix it is rebooting.
    Sometimes this will happen quickly, other times it may take an hour of browsing before the internet stops working and the tell-tale sign of the loud fans
    makes an appearance.
    All other features of the laptop work, just not the internet. Across all browsers too.
    Thanks in advance,
    Finn

    The only way to know what is going on is to retrieve the certificate and check who is the issuer.<br />
    It is always possible that the server doesn't send the full certificate chain (intermediate certificates), so it might help to post a link to this website
    Check the date and time in the clock on your computer: (double) click the clock icon on the Windows Taskbar.
    Check out why the site is untrusted and click "Technical Details to expand this section.<br>If the certificate is not trusted because no issuer chain was provided (sec_error_unknown_issuer) then see if you can install this intermediate certificate from another source.
    You can retrieve the certificate and check details like who issued certificates and expiration dates of certificates.
    *Click the link at the bottom of the error page: "I Understand the Risks"
    Let Firefox retrieve the certificate: "Add Exception" -> "Get Certificate".
    *Click the "View..." button and inspect the certificate and check who is the issuer of the certificate.
    You can see more Details like intermediate certificates that are used in the Details pane.
    If "I Understand the Risks" is missing then this page may be opened in an (i)frame and in that case try the right-click context menu and use "This Frame: Open Frame in New Tab".
    *Note that some firewalls monitor (secure) connections and that programs like Sendori or FiddlerRoot can intercept connections and send their own certificate instead of the website's certificate.
    *Note that it is not recommended to add a permanent exception in cases like this, so only use it to inspect the certificate.

  • Very Loud and Never Stopping Fan

    Hi,
    I purchased my HP laptop in September 2010 and for the past few months the fan runs constantly and is very loud. Even after shutting down my laptop for hours, upon start up the loud fan begins. It has gotten so loud and distracting that it is now hard to focus and use the laptop.
    Any feedback would be appreciated. I remember when buying the laptop something about a year warranty on hardware. Does this exist? This issue needs to be resolved.

    Well, the never stopping fan can be due to a number of factors, most usually:
    1)      You have a dust build-up in your heat sink (which may not be apparent by just looking through the vents). Unfortunately your computer’s cooling system also acts as a vacuum cleaner to all those table tops it has been on. It is a common nuisance after over a full year of work. Cleaning it up may require disassembling the whole computer, since the heat sink is inaccessible on many computers. (Word of caution: if you are thinking of using “Canned Air” to blow the dust out, be very wary that you may destroy your fan bearings if the canned air makes the fan blades rotate too fast!)
    2)      CPU may be under constant load (maybe some new buggy software update was installed?) – Check CPU Load on “Task Manager”.
    3)      The GPU (graphics card) may be running always at full speed, thus increasing the heat inside the unit (change GPU profiles to “Battery Optimized” or such).
    Finally, do use a program such as “CPUID Hardware Monitor” to read out the temperature sensors inside your computer. You can better understand at which temperature the fan kicks in and why the temperature is rising to that target.

  • 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!!! ;)

  • Loud fan/whirring and heated MacBook Pro

    Hi,
    My MacBook is continuously loud and it seems to be the fan - does this mean it could be near death? I have to admit it sounds like a PC and I can't do my work in peace.
    Also, the unit gets extremely hot above the keyboard and below the screen.
    Anybody know the problem before I have to scrap the love of my life???
    Thanks.

    Exactly how much CPU is Firefox using? If that is causing the problem then I'd suggest using Safari or another browser.
    I think it is wise to upgrade your RAM to 4GB particularly if Activity Monitor indicates you have low free memory. With 4 GB your machine should have a nice performance increase so I'd recommend doing that soon.
    You never stated how what you are doing when the fans begin getting loud, if you have a lot of processes open and are operating with only 2 GB of RAM you are taxing your machine.
    I'm sure there is nothing wrong with your CPU.
    BTW do you turn off your machine when not being used, if you do that isn't recommended. I'd recommend following Apples instructions in the owners manual.

  • IMac 2007 20'' black screen and fan loud

    Hi, I have a imac from 2007 and i got it from an other person that said to me that the problem was the rams, and i got the rams and the screen continues black and the fans loud.
    Thank you.

    Hello brunofig132,
    Thank you for using Apple Support Communities.
    I understand that your iMac is booting to a black screen and loud fans. The following article provides steps to troubleshoot the startup process for your iMac. It should give you an indication of what might be causing the problem. 
    Your Mac won't start up in Mac OS X (Mac OS X 10.3.9 or earlier) - Apple Support

    I suspect you didn't reset it right.
    Turn off the machine, let it charge up and then try the SMC reset again.

  • G575 - Fan stoped working, CPU overheats and Laptop shuts down

    Hello!
    I've bought a Lenovo G575 three years ago, my warranty isn't active anymore.
    The fan in my laptop stopped working yesterday, and now when I do something that is CPU intensive, the Laptop shuts down because of the overheat.
    Is there a way to buy a new fan?
    Should I open the laptop and take a look at the fan, to see if it can be fixed without changing the fan.
    Thanks for the replies.
    Solved!
    Go to Solution.

    Yes, the listed fan will fit your model laptop.
