Added Ram to Mac Mini & Now There is Loud Fan Noise

Hi everyone,
Today I bought a Mac Mini Core Solo. I brought it home and opened it to add an additional 1gig of ram. I now have 1 stick with 1GIG and 1 stick with 256mb of ram inside of it. After adding the additional ram I closed the case and turned the power on. It picked up the new ram but it is now making a really loud fan noise. I'm nervous that something has gone awry. Any suggestions for as to what is wrong? Did i do a big bad?
I'd appreciate any advice!

Sounds like a connector to the fan was pulled loose when you dismantaled the mini to get at the memory slots.

Open her up and check that the wires from the fan a re seated onto the motherboard correctly.

  • Mac Mini won't boot loud fan.

    I left my office only to return to find that my Mac mini had turned off. I tried to turn it on, the light comes on, and the fan comes on (very loud). But that is it.
    I have had it less than a year with no trouble.
    Anyway I have tried resetting the PRAM. Any ideas?
    Thanks.

    Reset the SMC, as per > Resetting the System Management Controller
    1. Shut down the computer.
    2. Unplug the computer's power cord.
    3. Wait fifteen seconds.
    4. Attach the computer's power cord.
    5. Wait five seconds, then press the power button to turn on the computer.
    If that does not resolve the problem..?
    Run the Extended Hardware Test, as per > Using Apple Hardware Test
    If that does not work or you encounter a hardware problem, contact your local Apple Store or AASP using > Apple - Find Locations and have the Mac Mini checked out.

    It is standard Mountain Lion error due to the networking ability which is comparable to wet string. (actually that was lion.. it dried out some with Mountain Lion.. higher in the hills perhaps!!)
    See C12 and C17

    But many people are suffering the same issue..
    And the above is even a little out of date.. you might need to do a reset to the TC.

  • Is it worth it to buy a Mac Mini now?

    I was dissapointed that they didn't announce a new Mac Mini yesterday.
    I was ready to order the new version.
    So my question now is, is it wise to order a Mac Mini now?
    I currently have an iMac from early 2009, and it is showing it's age. I have upgrade the ram, but it still struggles bit. The max ram is 8 gig.
    I want to replace the iMac, but wanted to replace it with the current technology.
    The Mac Mini hasnt been updated since 2012.
    Any advice?
    Thanks
    Len

    I had a 2008 iMac and replaced the HDD with an SSD.  Like night and day.  However, not sure if it was 2009 or 2010 where the iMac changed the HDD design to include a temp sensor.  If you replace that type with an SSD your fan speeds will go to max as there is no temp sensor.  There are ways around this with some mods. so Google first to check if you can do this.  I recently replaced my iMac with the MIni hooked to a TBD and it has been great.  So much faster than my iMac. (faster CPU and more Ram).  My Mini also has an SSD.

    you know the invisible arrow that appears in the additional tabs pages in "Numbers program"
    Especially an inconvenient for previous Numbers users as you all know.
    any word on New Numbers Tutes at all??
    You'd think with a Billion dollars they could make a 10 min clip saying here are changes guys, go enjoy new layout.....  Just saying...  not.
    anyway Hi and any help out there tonight is GREATLY APPRECIATED.
    Cheers Jason.

    If the reset doesn't work:
    FORCE IPAD INTO RECOVERY MODE
    1. Turn off iPad
    2. Turn on computer and launch iTune (make sure you have the latest version of iTune)
    3. Plug USB cable into computer's USB port
    4. Hold Home button down and plug the other end of cable into docking port. Do not release button until you see picture of iTune and plug (very important)
    5. Release Home button.
    ON COMPUTER
    6. iTune has detected iPad in recovery mode. You must restore this iPad before it can be used with iTune.
    7. Select "Restore iPad"...
    Note: Data will be lost

  • I dragged my ext. HD iTunes backed up folder into my new mac. Now there are duplicates of every song!! The problem is both versions seem to actually BE there when I check the info. Now I have no idea if iTunes is playing the files in the trash or not

    Hi. I'm in a situation here and would really welcome some guidance. I dragged my ext. HD iTunes backed up folder into my new mac. Now there are duplicates of every song. Both versions seem to actually BE there when I check the info. So, I moved what I thought were duplicates into the trash from iTunes, and resigned myself to the fact that I would have to do this manually for each album. I did this with about 10 albums. I emptied the trash and lost them even though they still LOOKED like they were in iTunes. I repeated the process tonight on a bunch of other albums not realizing yet that I had screwed up terribly the first time. This time I saw what had happened and pulled the files out of the trash, onto my desktop and dragged them back into iTunes, then deleted the duplicate files that had exclamation points next to them. Now I have no idea if iTunes is playing duplicate files from the trash or not, and am nervous about emptying the trash. Anyone dealt with this before? Thank you

  • Is that true, use 16 Ggo RAM on mac mini mid 2011?

    is that true, to use 16 Ggo RAM on mac mini mid 2011?

    macsales.com (other world computing) is a good source for quality RAM and says "yes": http://eshop.macsales.com/shop/mac-mini/
    crucial.com is another trusted source of RAM.
    Be sure you get the correct RAM as advised by the website and do not try faster RAM.

  • If I purchase a mac mini now - will Mountain Lion be avilable free?

    If I purchase a mac mini now - Will Mountain Lion be available free - or should I wait to purchase the mac mini?

    No. It will come with Lion installed. A free upgrade to Mountain Lion would only occur when Apple announces such an option, and only to those who purchase the computer within some period of time after ML is released.
    If saving $30 or so to upgrade to ML is your goal, then wait until it is released and Apple initiates an Up-To-Date program.

    Do you have a Time Machine backup or clone?  If not,
    all is lost if you have in fact deleted your OSX partition
    and you will have to do a reinstall from Recovery HD
    and install all else.

    Installed 8gb RAM on mac mini model A1347 but it won't recognize past 4gb, any way to fix this to recognize the full 8?

    What RAM did you buy?
    Try reseating the modules, they need to be pushed firmly into the slots before tilting them down into the clips.

  • Loud fan noise on mountain lion, Mac Pro early 2008

    Hi there,
    I've recently installed mountain lion 10.8.5 lon my Mac Pro , early 2008, 2,8 GHz, 24 gb ram, 2x ATI Radeon 2800 XT.
    To give it a clean shot i clean installed it on a sep. Partition, no upgrade from my previous Snow Leopard.
    The Machine usually works quiet, i've measured via Isat Menu:
    exhaust fan: 681 rpm
    HD/expansion: 1100 rpm
    After running Mointain Lion, latest update version, i get a much louder fan noise than in snow leopard:
    exhaust fan: 845-950 rpm
    HD/expansion: 1500 - 1800 rpm
    The activity monitor shows no significant CPU usage, only the kernal has over 90 threads constantly running.
    I've heard that this is a known issue but it's never been resolved. SMC and PRAM reset did not work at all.
    when i go back to snow leopard everything gets back to normal. Yosemite is even harder on fan noise than mountain lion
    so i've rolled back to mountain lion.
    Any idea ?
    dezzo

    no one here with the same problem on an early 2008 Mac Pro ?

  • Mac Pro will not boot, constant loud fan noise and nothing else

    hello,
    earlier tonight,i put my mac pro on sleep, then later on, when i wanted to take it off sleep and use it, it made the loud fan noise, which it always does but goes away, but this time it the fan wount slow down and the loud noise stays and i dont see anything on the screen. im guessing the fan noise is the ATI x1900 card...
    any help please..i just bought it 2 months ago...

    Hi, here are the steps I would go through. I would unplug the Mac Pro completely from everything and look at the video card's fan intake to make sure it isn't plugged and just make sure everything "looks" correct. I would then plug the machine back into one monitor/keyboard/mouse (leave all the other peripherals disconnected. Once that is done push the power button. Does anything happen? If not then if you have another mac and an external hard drive, make a copy of the OS on the drive and see if you can get the Mac Pro to boot off that drive. If the video card doesn't work then it will not show anything when booting off an external drive. If the external boot does work then I would suspect that you have a bad hard drive (or it crashed). At that point I hope you have a back up of all your data and such.
    Mind you these are steps I would go through. What a nightmare. One other thing to check, make sure your monitor didn't die.
