24" imac overheating problem

This 24" Apple imac computer is fantastic in all ways that I've used it, yet my 24" imac has been recently overheating and shutting down without notice. As a mechanical engineer looking over the design of this flat screen PC at the back I note the cooling fins are the wrong way round for maximum cooling, so assume this is a manufacturing defect because heat rises upwards not downwards.
So do Apple management accept the flaw in the design of the imac 24" with the direction of the cooling ducts and rectify the problem as soon as possible, or do they ignore this problem in the cooling system of many imacs distributed around the world?
The imac 24" is a fantastic machine to use, and by Apple tech turning around the cooling vents by 180 degrees the venting problem will probably disappear.
Sometimes the simplest of solutions are blindingly obvious!!!

i get what u mean about the vent, i was thinking the same thing BUT;
i was reading something on wiki a while ago about the OLD apples, i mean real old like the SE (i think)...
- they initially didn't have fans and they used to overheat (more so when people rested papers on top blocking the vents) - but their design was to allow the heated components situated towards the top to actually draw cold air through the bottom of the machine and up inside - past other components and out the top and hence cool it effectively, then apple started using fans...
- i think apple still use a combination of fans and the radiated heat to cool the imacs of today, the components that get hot are situated at the top of the aluminum macs and the aluminum itself heats up allot which makes it radiate the heat outwards like a heatsink and then fan kicks up to help it along when needed, maybe the design of the vent helps this process? i.e. the vent causes the aluminum to heat up more and radiate more heat than if it were the opposite way - perhaps if it were the other way, the fans would have to run a tiny bit higher and possibly over time suck more dust in and create more problems?
couldn't find the article on the apple computers to what im trying to communicate here - dont remember the right terminology to explain it all properly but try researching heatsinks on wiki - heatsinks work on the same sort of process

  • IMac overheating problem? This may help in some cases!

    My daughters iMac frequently suffered of a kernel panic after about 2 hours of use. Symptoms lead to suspect overheating of some component. How I fixed the economical way:

    Hi Topias,
    Tervetuloa!
    Thank you for this excellent page and the useful links.
    Glad to know such good contributors like you are around...
    A very good work indeed.

    P.S.
    The air is meant to be sucked from bottom, through the computer, to the top.
    But have you by chance tested the reverse: blowing air from top, through computer, to the bottom?
    I mean, with such an external, noisy installation, you can allow yourself pure efficiency (and a more powerful fan), since you don't care anymore about design and noise?

  • Windows 7 64 bit on iMac display problems and instability

    I received my iMac 27" quad core with 8 gig ram & 2 x 1 TB hard drives last Friday. I'm using Boot Camp to run windows 7 64 bit on maximum 2560 x 1440 screen resolution.
    I get intermittent but often display problems in windows 7. I get areas of the screen covered in little yellow dots or blue squares (never red artefacts.) This will happen at random areas of the screen, inside an open window, around borders of windows and so on. Most often the screen will go black and come back with a message in the bottom right corner of the screen saying 'Display driver has stopped responding and has recovered' with the sub message saying 'display driver ATI radeon family stopped....etc'. Sometimes I lose the screen wallpaper. Once I've had the system just shut down, once I've had Photoshop seize up and I had to do a cold reboot. Could this be an overheating problem or resolution too high problem or driver problem? Windows 7 tells me my drivers are up to date. I tried installing the drivers for the card from ATI's website which made no difference
    The reason I bought a Mac is because it's the only effective way to code for the Mac family of OS's in XCode. The reason I didn't just attach a miniMac to my PC monitor was because there's rather a lot of advertising by Apple about the fact that you can use a Mac with a PC OS via Apple's own Boot Camp. Now I have a lot of Windows software (some of which is not available for the Mac or requires buying again) sitting on an unstable system. Any ideas would be much appreciated...

    Sorry, that thread got moved for edit and as a user tip... which I didn't want and won't be doing....
    Here is the post:
    A tip and workaround for how to get ATI mobility/laptop drivers so that Windows no longer thinks the ATI is a desktop card:
    http://discussions.apple.com/thread.jspa?messageID=11286987
    Summary (my own edit steps):
    1. Install Boot Camp 3.0 and upgrade to 3.1
    2. Uninstall graphic drivers and run Driver Sweeper
    http://www.guru3d.com/category/driversweeper/
    instead of:
    removing the crashing driver by going into windows 7 setup via its install cd and deleting the ati driver manaully
    3. Install ATI Mobility (link)
    4. Uninstall ATI (Programs control panel?) Device Manager (rollback; uninstall?)
    5. Device Nanager: update driver and BROWSE BACK to 8.681 (the original apple driver that was causing freezes and purple artifacts) - navigate to /Apple/Drivers/ATI
    (Apple uses) a 4850 card in the iMac, its modified a bit for apple. Enough that desktop drivers don't work, and modded-for-laptop desktop drivers don't work either.
    Now the upshot of using modified drivers is that it FORCES the catalyst control panel to be installed, meaning you get a few more options to mess around with the card.
    I couldn't use the original apple drive, it locks up, the newer one had banding, the newer radeon drivers direct form ATI wouldn't work until they were modded and then they cause black screens.
    SO the solution, as obscure as it was, was to download ACTUAL mobility Radeon drivers - version 10.3 still, but made for laptops.
    http://support.amd.com/us/gpudownload/Pages/index.aspx
    THESE drivers I was able to install - and here is where things changed.
    THIS driver changed they way windows saw the video card in device manager.
    As I mentioned before, its NOT a desktop card, its a modified laptop card, but installing mac drivers makes windows THINK its a full desktop card, and running the original 8.681 driver crashed it.
    Once installed 10.3 LAPTOP driver it now appeared in device manager as a MOBILITY card.
    +These Steps "should" work:+
    delete ATI driver manually
    reinstall apple driver after that and see if that works,
    otherwise try the steps above
    (mod drivers, remove via windows recovery off setup disk, install laptop drivers, reinstall apple driver over it)

  • Imac Overheating

    I have a major overheating problem in my 24" imac.
    When the problem began I suspected the hard disk, but I have ruled it out. The behavior of my machine had become sluggish and sporadic over the last month. This week it became nearly useless. It would "pinwheel" for no reason. A right-click would result in a five-minute "pinwheel" before the menu would pop up. It would be completely unresponsive. It would freeze during burning or just copying files and then start again. Open a folder and view the items inside and have no ability to scroll. Oddly, while doing that, it would slowly report the sizes in the file size column. (one about every second)
    I've run a handful of utilities on the Hard Disk like Disk Utility and OnyX. All things say "OK." I did repair the disk a week ago and many corrections were made then but not now.
    I ran AHT and get the following errors at different times:
    4MOT/1/40000003: HDD-1333
    4MOT/2/40000004: HDD-1350
    4HDD/11/40000002: SATA (0,0)
    Most of what I have read in various forums suggested the fans and temperatures. So, I ran "temp monitor" and noticed some alarming temperatures. The HDD in particular was reading 176F^. So I concluded that I lost a fan. Thus I ran smcFanControl and ramped up the fans one at a time. They all sound good and I can detect wind around the machine.
    Now it was "crunchy" and very frustrating to get the apps to start even after shutting the machine down to let it cool. However, once the fans started to run, temp monitor reported significant cooling and the machines behavior straightened up IMMEDIATELY.
    Something has been degrading over a longer period of time. Actions by the machine were more crisp and more responsive than they had been in a much longer period. I ran photoshop and tried to force a crash. Nope. Like new.
    OK, so what is the issue? If I drop out fan control, the machine gets sick and dies? What is the apple failing to do on its own to regulate temperature?

    If you search through previous posts you'll find it's quite normal. The aluminium chassis forms part of the heat sink of the iMac, if it gets too warm it'll increase the fan speed, and as a safety measure would eventually turn off, but it's safe and normal for temperatures to reach 85+ degrees Celsius.
    I think you have a hardware failure not induced by heat, as you say the fans are working and the temp's are not really that excessive that your getting.
    If he's getting error messages running AHT, it probably is a temperature sensor or fan failure of some type. It's difficult to know, because we're relying on the accuracy of a 3rd party utility to tell us if all of the fans inside the machine are working, and often these change via model.

  • CPU Overheating problem on Windows 8.1 Pro (installed with BootCamp)

    There is a really important overheating problem on windows 8.1 (installed with bootcamp) even i do nothing Cpu is 50-60-70 Celcius degrees. This is really annoying problem. Most of users necessarily need windows OS for using third part programs that doesnt exist on OS X platform. I think this problem is important and has to be fixed as soon as possible.
    My brand new Mac:
    MacBook Pro (Retina, 15-inch, Mid 2014)
    2,5 GHz Intel Core i7
    16 GB 1600 MHz DDR3

    I have the same problem on macbook pro retina 15 late 2013 - top configuration

  • Macbook Pro overheating problems.

    I am running OS X Lion on my Macbook pro (late 2008) and it has been over heating for the past 2 months. I noticed that it was getting warmer than usual initially but now it gets too hot it comes up with the grey screen and forces me to do a manual shutdown. I can't even turn it on immediately because I think the it's so hot the pre-boot up check realises it's so hot for it to be start. I get 2 beep sounds and a pause whenever I try and turn it on after a forced shut down. I normally have to wait for it to cool down before I can turn it on again. I have tried cleaning the fans but that did not help. I should take it to the Apple Store but I don't want to give away my laptop for a week or so hence why I am trying to solve it myself if it's possible. Any ideas? My guess is the heat sinks not being as effective as they used to be?
    Thanks,
    Omar

    about my experience in kernel panics, mbp 17 no boot, freezes etc etc, i would recommend an Apple Authorized Repair Center as soon as possible. there are many thing that can goes wrong. Gpu and Cpu becomes very hotter during normal usage and if there aren't some slowing down performaces, it seems normal. A couple of week ago my mbp 17 core 2 duo start to freeze sometimes. Sometimes very often. My first think is an overheating problem due to intense cpu and gpu works but after a while, i realized that is totally random. my mac can stay on in idle mode for hours and freeze as soon i open firefox or safari to load a youtube vid.... and vice versa. Smc gave me an illusion but if there's an hardware problem, soon or late, it occours again. to be honest, ear fans at 6200 rpm most of the time is kinda annoying and noisy. So i decide for the apple authorized repair center. they diagnose a faulty nvidia gpu and after replacing the whole logic board, my mbp seems brand new. it becomes hotter as a brand bew one but it's absolutely normal. it's a laptop..no cooling fan like many others but only 2 fan to extract hot air from inside to outside.... it have aluminum chassis and this work like a big cooling system.
    there are many little pieces on the logic board and a faulty one can be a problem. A broken thermal sensor or a broken diode can compromise some other pieces to work in the right way. So, don't waste your time searching  a band-aid to your problem.... take it to an official repair center.. they know how to solve your problem.... at least, they do a try :)

  • Servere overheating problems on my T500 =/

    i've been having overheating problems for about 2 month now, basically have had to keep tpfancontrol running to keep from shutting down, constantly 95c ish. goes up to 110c and than shuts down. I cannot even reinstall windows without significant issues. I've tried reseating the heatsink/clear dust/reapply thermal paste but it does not help at all. I haven't called warranty yet because I didnt want to have to send it in but I checked today and my warranty expired on the 8th on this month =[. any idea how much it would cost to repair? I'm hoping visa extended insurance will cover the repair costs

    there is probably a problem with the heat sink, you may need to get it changed. The heatsink contains several heat pipes which use a relative low boiling point fluids like acetone, where the heat of the cpu and GPU is carried away through the evaporation and condensation process. If the fluids in the heat pipe somehow leaked out, then the heat conduction from CPU or GPU to the fan, would be purely through conduction through the copper materials, which is insufficient, hence the high temperature in the CPU.
    The other possibility that the thermal grease between CPU/GPU between the copper heatsink is either too thick or insufficient, and there is large voids where the heat from the CPU can't be efficiently conducted between the CPU/GPU to the heat sink.
    So you must get warranty to look at it and change out the necessary part.

  • Imac display problem, the resolution seems to be unusual, top bar and all folders on the desktop background is off the screen

    Need help with 21" imac display problem. The resolution seems to be unsual, everything on the desktop background goes off the screen. The resolution is set at 1920 x 1080

    Quit the game and restart the iPad.
    To quit the game - Go to the home screen first by tapping the home button. Quit/close open apps by double tapping the home button and the task bar will appear with all of you recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner to close the apps. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
    If that doesn't work try this.
    Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

  • GT60 2PC Dominator - Overheating problems

    Hey guys,
    I am getting desperate here. My 6months old Dominator has been lately suffering from massive overheating problems - 90C+ which happens after in a short while after launching any Dx11 game (but many Dx9 suffers from the same). I have tried two different cooling pads Zalman and now Cooler Master N-1 that has positional fans which I have moved underneath the GPU+CPU, but computer behaves like they are not there, so it is virtually no good at all.
    What happens when PC gets into overheated state is that game starts massively to stutters both audio and video in terms of freezing in and out in short intervals that even ensues in Wind when I close the application. I wanted to check out whether the thermal compound has not been reduced, but comp is still sealed and after 6months that seems rather suspicious.
    What do you recommend ? Are there any other cooling solutions for laptops other than ineffective cooling pads ??
    Cheers

    Hi,
    What country do you live in? As in EU (at least as far as I am aware of) opening notebook for repasting (or adding RAM/HDD/SSD) is OK and doesn't void warranty. However if you prefer to hear an official statement, contact MSI. If you live else where, then opening very likely voids the warranty.
    >>How to contact MSI.<<
    At last you can RMA the notebook.

  • [GX620] MSI GX620 Overheating Problem

    Hello,
    I have a MSI GX620 laptop and it overheats all the time when playing games (World of Warcraft)
    When playing the laptop just randomly shuts down after playing for a while.
    I am using a USB cooler to get rid of it but it doesn't seem to help in any way.
    Can someone please help me to fix this overheating problem since it is very annoying and I just can't get rid of it.
    It's been good for a week and now it just happens to shut down very often.
    Thanks in Advance,
    Sam

    Please note that Arctic Silver is slightly conductive. If you're going to use this, be VERY sure not to spill any or that you don't use too much.
    If it does spill and gets in contact with the small pins around the core you might create a short circuit.
    I recommend the following best tested thermal pastes:
    -Prolimatech thermal compound
    -Tuniq TX-3
    -Arctic silver 5 (slightly conductive)
    -Arctic silver ceramique
    -Enermax (Dow Corning TC-5121)
    -Thermaltake thermal compound

  • MSI GT70 Dominator Pro - overheating problems

    Hi all! I'm very interested in buying that notebook, but i've heard a lot about msi's overheating problems and it worries me. I am aware that gtx 880m requires a lot of cooling and i would like to know if those infamous overheating problems have been fixed ? i don't want to spend so much money on something that works for a month.... I play a lot and i am very demanding in this case, so i predict i'd be playing 4-5h/day on max settings. Will i have problems ? what to do to avoid it ?

    You know what?  I already buy it in china.  and it's really high temperature .
    For example. I play Call of duty 10, and no matter I open the full effect or normal effect , the temperature always can be 93C  .  I see the Weather temperature is only 20.  and If I'm play Batman:Original    full effect same problem, the 880m temperature is going to 90+ .I'm use normal effect and close the Physical , then the temperature on 82-85....
    I'm very confuse,  If the 880m very high temperature .... why use it on laptop.... because if always a high temperature, you really not  good feeling to play anything, because high temperature will let you laptop retired more fast.
    Any way I also buy a cooling pad, but looks like not any working....maybe that about the laptop inside design....
    well, I search on Internet about GT70 design, and I think maybe the original thermal paste not good. So I buy IC Diamond 7 Carat ICD7 ,but I'm not use it yet. because the MSI chinese customer service tell me if you change it or reload it , They do not offer the warranty........looks like a joke......then what now.....?  I don't know , some friend told me , it's fine to change the thermal paste, but I still warry,  and I'm not continue play the game anymore....because every time the temperature on 90C. I don't any desire to play.
    GT70 only 1 Fan for Radiating, not 2 like ROG or Alien, maybe that is a dead design.......
    So, these all true story, and if any one has any idea or any advice, please tell me . thanks.
    any way I just search the GT70 temperature problem and I in here join every one, so sorry for my bad English.
