Loud and Hot

I bought my G4 MDD recently of Ebay and it is deffinetly the version nicknamed 'Windtunnel'. Its very loud, and hits high temps of 122°F. I know apple released a power/fan replacment kit shortly after the MDD release in 2003. But it is unavailable now from what I understand. Any suggestions for fan replacments/new heatsinks.
P.S. Can someone tell me the pros/cons of useing a copper heatsink to replace the stock aluminum one?

122 degrees F is not that hot for internal temps for CPU or inside your MDD. temps of around 140 degrees are common even. as long as you have an effective cooling system your computer should run fine.
well Copper heatsinks definately cool better. I bought a copper heatsink online and replaced it with the old aluminum one and notice approx 10 degrress cooler temps than previous. Copper handles heat better and cunducts electrical current better, hence the reason its used so much in A/C cooling, plumbing and wiring.

  • 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.

  • When I play minecraft my computer gets loud and hot.

    When I play minecraft on my macbook pro, my computer's fan turns on which is very loud, and also my computer gets hot.  Normally this wouldn't be a problem but I make Minecraft Youtube videos and it sounds bad in the video.

    Sometimes this happens when the computer has to do a lot of work.... What I mean by that is if you have other applications open or applications that are running it has to work minecraft which you are in and the other apps that are running.... To prevent this from happening is when you are playing Minecraft only have like 1 or 2 apps open in the background at a time and none running then the fans don't have to kick in and make the computer get hot. This has happened to me and I did exactly this and it stopped after the first try of doing it.
    Hope this helps,

  • Late 2011 17' MBP suddenly got very loud and hot

    http://i.imgur.com/tZ1QZJM.png?1
    Was using handbrake when suddenly the fans got loud and stayed like this for several minutes before I decided to cancel my DVD rip.
    Looking at iStat the Fans were at 5,500 RPM & CPU at 185.
    How bad was this? On occasion this happens but never for more than a few seconds.
    Any suggestions?
    Also I just upgraded to Mountain Lion last week, if that matters.

    i'm afraid it didn't work....
    it's like brightness control got stuck on lowest. If I shine a light on the sensor left of the iSight, the keyboard lights turns off, so the sensor works and shouldn't be the source of the problem.

  • My mac is really loud and hot

    I have a 13 inch Macbook pro. It is running slowly, not holding a charge, taking a long time to charge, staying very hot, and constantly sounds like an airplane attempting to take off.
    This has happened once before, and the tech in the Apple Store went into my settings and did something along the lines of clearing out my usage history. It was as if the computer was still trying to run programs even after I had closed them.
    Any ideas? I'm getting into finals and can't afford computer problems!

    update: I found my Activity Monitor window, and this is the resulting data:
    Even with every program closed, it still exhibits the same symptoms. Thoughts?

  • White Macbook (mid 2006) Runs loud and very hot,  battery not charging

    I know my Macbook is getting a bit old now, but I don't think the way it is running is very normal.
    The battery will say that it is fully charged, but it will only last about half an hour when disconnected from the charger. The light on the charger will not come on either, or it will blink when i attach it, then stay out.
    My Macbook will also run very loudly, and hot. I don't ever run too many programs at once, so I know that it's not a strain on the system from what I can tell.
    I tried resetting the SMC since it sounded like the problems I am having would be solved by resetting it.
    Are there any known problems such as these, or fixes? Thanks.

  • I-Pod Hard drive loud and doesn't work

    I've had my ipod for about a year now and have thoroughly enjoyed it. However, last week it decided to stop working all together. When I turn it on the apple symbol comes up and the hard drive gets real loud and hot, nothing else. After a few minutes it either shuts off or runs till the battery dies. Finally, when I connect it to my PC nothing happens. It's not even recognized as being there. The only thing I can do is reset it, even after talking to tech support and trying to run through the diagnostic buttons, nothing happens. I can't seem to find any of this in the forums.

    I have exactly the same problem since 2 days: My iPod 4G (40 GB) died. More specificly, the harddrive is out of order. I formated it, updated via the iPod update application, but it still has severe problems and they become worse. For example, I can hear the iPod trying to start several times until it is up and running (sometimes it never makes it). Or, when I copy songs on it it suddenly freezes. Or, when I try to play a song, it is not able to open it. As I said, it's dead or at least dying.
    It is out of warrenty, however, I got this iPod as a replacement for a previous one during it's warrenty in summer 2005. I guess it only can be solved with a new harddrive (or a new iPod ).
    Any experience with Apple's policy in such cases? The harddrive should not be dead after a few months.
    Is there a (free) diagnostic tool available to find the exact reason?

  • 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.

  • 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!!! ;)

  • 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.

    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.

  • I have good headphones and would like to be able to listen to music louder and possibly with better quality audio. Any advice?

    My old iPad had the 30 pin line in and I had an LOD cable which I ran to a headphone amp. This allowed me to use the headphone amp to control volume independent of the iPad as it was docked through the LOD. This made it louder and sound better than simply using the headphone line in of the iPad. I don't know how I can do this with my iPad Air 2 as I don't know of any cable that would connect into the 8 pin line in. I've looked for LODs to fit the 8 pin but can't find one. I bought a cheap 8 to 30 pin adapter but it only allows me to charge and sync, not dock. Does anyone have any suggestions?

    The apple lightning to 30 pin works just fine for me.
    Works with a fio amp and srs  iwow.

  • HF-300 Sound Quality - Loudness and Distortion

    Hi,
    Just wondering if anybody has any comparative testing on the sound quality and loudness with this unit. I am not sure if mine is faulty or just the best that can be expected from the speakerphone.
    Problem is (tested using n95 8 gig and n80) that once the volume is turned up to 70% or more the units sound is distoted terribly. Sounds like the speaker is vibrating and crackling. The symptom is like when you turn up the volume on any speaker beyond its capability which then gets that distortion/vibration effect.
    That said when used below 70% volume its too soft to be useable for everyday driving conversations.
    Golden question if you own the HF-300 also is can you put it on 100% volume and have loud and clear sound without any negative sound quality? May help if you mention what phone model you have tested youyr with also.
    I really think it must be a fault as everything marketed and reviewd about these units states 'loud n clear'. Surely its meant to be used on 100% also without such distortion or why have 100% volume possible.
    Message Edited by quozl on 25-Jul-2008 07:20 AM

    Sorry to ask again but is the car kit installed with an additional single Nokia speaker or is all audio played through the car audio system (original car speakers)?
    Most likely in the second case is that the installer has routed the audio incorrectly.
    The kit has two outputs: stereo for music and mono for calls. Mono calls can be installed to run through the single Nokia speaker but musics should be installed to run throught the car stereo 'aux in' channel, hence the question about what audio is distorted.

  • Can I have loud and vibrate on phone only?

    I have an 8330m and would like my ring to be loud and vibrate at the same time and only ring for phone calls. Eveb my cheapie phones could do that. Help!

    yes it is possible through the sound profiles if you use OS5. Just edit one of the sound profile, for example the one names "Phone calls only" and set what you want to set.
    if you are still with OS4, the standard option lets you "vibrate then ring" or "ring" or "vibrate". If ou wish to have "vibrate and ring" you need a third party application to do that.
