Imac high fan speed and goes to sleep 10sec after wake-up

Hi,
Since today my imac's fan speed is high (optical fan and cpu fan speed at: 4000rpm)
Done a hardware test wich gives me 4SNS/1/40000001:IDSR-0.000 indicating something with logic board. According to istat all my temperatures are below 35°C (95°F). istat has readings for the cpu and optical drive temp (both around 26°C)
On top of that if I put my imac to sleep after wakeup (give or take) 10sec later it would go to sleep again. tried the smc reset procedure. no success
Any other tricks to try or just go for an exchange? (imac was bought on 2feb2010)

I've had this problem since replacing the MLB in my iMac a few weeks ago. Initially brought in for repair when the CPU fan came on at 4k rpm and stayed on even after SMC reset and nvram reset. First replacement MLB was a dud, second corrected the fan problems. Now I'm having the sleep issue, I can't tie it to any particular process. Initially I thought it was graphics related as it would go to sleep during graphics intensive work, but yesterday it was doing it when just copying data to an external drive. The temperatures of the CPU and the GPU diode are within spec. I now use a fan controller to keep the CPU fan at 2100rpm and the HD fan at 2100rpm and I don't have the problem. From what I can tell now is that a sensor is incorrectly reporting temperatures intermittently. It may not be the MLB or the graphics card specifically, but the cable connecting the sensor to the board. I ran AHT after the last time it did this and it failed a sensor, but after running ASD on the machine it passed all the hardware. I'm bringing it back into my shop later this month and if i can remember i'll post here with the resolution, not much I can do at home beyond software diagnostics.

  • Kernel_task high cpu usage, high fan speed, and low cpu tempterature

    Hi,
    I've noticed that a lot of people have been having trouble with the kernel_task process, but I couldn't quite find a situation similar to mine (most seem temperature related).
    Here is the situation (15' MBP, mid-2010):
    - on boot (while the apple logo is shown), the fans speed suddenly jumps, and stays there, even if the computer has been off for a while.
    - boot takes a little over a minute, which is considerably slower than what I was used to before today
    - when finally started-up, the activity monitors shows kernel_task using between 160-180% of the CPU!
    - temperatures are shown to be around 30C, except for the mem controller at 40C (still very low temp), but the fan speed is arround 6000rpm for both fans.
    - this happened out of nowhere, as I woke the mpb from sleep this morning.
    Since then I've tried:
    - multiple reboots
    - install all updates
    - uninstall flash player (some people where having trouble with that)
    - empty the system cache with Onyx (reported as a cause of slow boot)
    - reset PRAM
    - reset SMC
    - put some ice packs under the mpb to cool things even further!
    And so far, nothing has worked! I've had this laptop for 1 year, and nothing had ever failed. I upgraded to lion a few weeks ago, and everything had been working fine since the upgrade. This really happened out of nowhere, and none of the many forums I have read could offer a solution, and cals to apple support do not seem to yield better results (though I scheduled a call with them at 9am this morning, we'll see).
    Has anyone had a similar set of problems?
    I appreciate any help or advice you may have!
    Thanks!
    -Sebastien

    I have the same issue (2.66 2010 MBP Hi-Res Anti Glare.)
    I took it to Apple Store Covent Garden, JUST within warranty.
    18 days later my machine has a new Main Logic borad, heat sensors, top case, palm rest. etc.
    I turned it on.
    The fans kicked in. All processors at 50%, big ole kernal task.
    I took it back, geniuses rest SMC and tested it under load and it was fine.
    weirdly it failed diagnostics at first but then seemed fine
    I came home. Fans kicked in...
    I took it back. Diagnostics failed heat sensors again
    Replaced logic board and heats sensors again, but more carefully this time just in case, tested again.
    I took it home. FANS FANS FANS.
    Last time I was in the store I was told my machine was fine and had been thoroughly tested.
    In mac store, no fans.
    I erased hard drive and clean installed Lion
    FANS
    I replaced hard drive with OCZ SSD, clean LION.
    Fans
    Software update
    SMC
    PRAM
    permissions
    Onyx complete clean/maintenace
    FANS/CPU
    switched back to Snow Leopard SSD
    PRAM SMC ONYX etc.
    FANS/CPU
    replaced RAM, memtest-ed. fine, FANS
    gonna try again but up to nearly 2 months of all my spare time trying to shut this thing up so I can sell it.

  • High fan speeds and high GPU temperature during idle

    Hi,
    I'm hearing slight similar problems around this subject but this one seems to be obscure.
    My iMac 20inch (Early 2008 - 8,1) has just passed by the 3 year mark now and only yesterday just suddenly started haven't this weird gain in fan speeds mainly on the CPU.
    Checking the temperature in iStat shows that its coming mainly from the GPU (GPU - 79c / GPU diode - 91c / GPU heatsink - 83c) and that's from looking as I type this.
    I've done the SMC reset a few times and the PRAM reset too, but that's only managed to make things worse...occasionally on startup after the resets the screen will blank out and ask me to reset.
    Below are screenshots from istats of the state of my iMac during idle:
    Hope someone can help and this be of some help to others in the same situation.

    I think a SMC reset will handle this for you. If not then also do a PRAM reset.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.

  • High Fan speeds and draining battery

    Have any of you experienced this? Plug in the MPB when the battery is close to drained (10%). From that point onwards, till it charges to about 30% (some times beyond that to about 50%), the fans roar (literally) at close to 6000 rpm (and most of the time it is more than 4500 rpm). The laptop becomes an embarrassment to use, particularly because I use it (most of the time) in front of customers (typically CxOs). When this happens, the health of the battery is sharply eroded, and I need to replace the battery every 4-6 months.
    Support from Apple is whole different story.
    Thank you!

    *This is a problem I have experienced for about 18 months now. AppleCare expired late last year (2010). When it was in warranty, Apple replaced 3 batteries (from what I first reported the problem till AppleCare expired). Lots of parts (logic board, heat sensors etc., apart from the battery) changed. Things I have tried:*
    *1. System Controller Reset as described above.*
    *2. Battery use best practices (as described above)*
    *3. Complete system diagnostics run by Apple*
    *4. Reinstall OS on multiple occasions*
    *Other Observations:*
    *1. Finder consumes more than 80% CPU when this happens, please note reinstall of OS does not help*
    *2. CPU Temp is upwards of 70 deg C when this happens. My normal CPU tep is upwards of 60 deg C.*
    *3. GPU diode temp is above 70 deg C as well. My normal GPU diode temp is usually close to or above 70 deg C.*
    *4. No other applications running. So, Firefox, Office for Mac etc are all closed. Only apps open are usually Activity Monitor and Adium. Adium does not seem to make any difference.*
    *Finally, how does one connect with Apple Customer Relations? I see just Customer Service, which is support. I do not see any escalation point beyond that.*
    *Regarding Support:*
    *1. Apple Store support has been cosmetic in this instance. Replace battery was the solution on the first two occasions.*
    *2. Replace a lot of parts in the computer was the next option. See above for what was replaced.*
    *3. Over the past few weeks, it has been get Capture Data information.*
    *4. This problem started about 18 months before the AppleCare expired. Now, AppleCare has expired, but I do get help from Apple because it was a problem I reported when in warranty.*
    *However, I am not sure any one ever did a root cause analysis on this issue to start with. The result is a frequent trip to the Apple store, not to mention hours spent trying to get a solution.*

  • IMac (early 2009), 3.06 GHz, ATI 4850 - fan speed and temperature questions

    Well, so I downloaded and installed Temperature Monitor and iMac Fan Control - mainly for observational purposes and not for toying around with the fan speeds and I've got some questions. Mind you, I haven't tampered at all with the fan speed settings, just installed Fan Control. Here are my readings (while browsing the internet with Safari and doing a chat via iChat):
    Fan Speeds:
    CPU fan (desired) 1300 RPM / (current) 1530 RPM
    HD fan (desired) 2100 RPM / (current) 2099 RPM
    DVD fan (desired) 1300 / 1298 RPM
    Temperatures:
    CPU Heatsink: 92°F
    Internal HD: 108°F
    Internal DVD: 95°F
    GPU Heatsink: 107°F
    Are these, under the circumstances, normal readings?
    Thanks in advance for your replies.

    Your welcome and no problem. I would say only the Apple engineers can tell you why the fans are set to those speeds however my best guess is the obvious they found those speeds the closest to keeping the temps at an optimum operating temperature. I found when I'm doing graphics intensive work my machine heats up but quickly cools down when I'm done.

  • Intel imac 24" seems to overheat top LH corner and goes to sleep

    Intel iMac 24" - Since upgrading to Lion, my iMac keeps halting - particularly whilst playing back video - and goes into sleep mode.
    The iMac is very hot in the top left hand corner so I assume that there is a thermal safety cut-out that is putting it to sleep ?
    Tapping the keyboard a few seconds later staarts it up again but very soon heating issue causes it to go to sleep again.
    I've never opended it up so I don't know what componenet is sitting in the top LH corner that is getting very hot - suspect its the graphics card.
    anyone else had the same issue and know how it can be resolved ?

    Your machine is working kind of hard, the first thing I'd try is doing both a SMC and PRAM resets, in fact doing 2 of each wouldn't hurt.
    With only 493MB of free RAM you should upgrade. One thing you can check when you do this is to see if there is any dust that has accumulated on the intake port, this could be obstruction air flow. Do NOT blow are in but you can vacuum it out. I would recommend using www.macsales.com (OWC) and Crucial as vendors. I prefer OWC because they specialize in Macs so you know what they sell works, have terrific customer service and competitive pricing.  BTW OWC has how-to videos that show how to install RAM.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.

  • K8N Neo4 Setup - Issues Adjusting CPU Fan Speed - Alarm Going Off

    Building this PC for a friend, and I just got it to post.  Everything seems to be running stable, only when I get into the CoreCenter, the CPU Fan alarm is going off and the speed is flashing red.  It is currently running at about 820 RPM, but the CPU temp is sitting at 37'C and the sys temp is 32'C.  Is this too hot, is the fan speed way too low, I'm somewhat new to this.  I set it to Cool'n'Quiet and it still does it, I disable Cool'n'Quiet and try to increase CPU fan speed manually, and it won't increase.  Any input would be greatly appreciated.  The rig is setup as follows;
    MSI K8N Neo4
    AMD 64 3000+
    Kingston 512MB DDR400
    80GB Seagate ATA
    nVidia GeForce 6600GT 128MB
    Antec NeoPower 480W

    You can adjust the alarm level by clicking the little red arrow(Hardware monitor option) on the right side of Core Center, move the slider for CPU Fan Speed Alarm to the left(set it to 500-600rpm), and click OK.
    Now you shouldn't get alarms any more.
    The fan speed and temperatures you report are very similar to what I see on my system at idle. The fan shold begin to run faster if the system is under load for some time.

  • Streaming audio from my IPAD to my Apple TV from Rhapsody application.  when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode.

    I am Streaming audio from my IPAD to my Apple TV from Rhapsody application.  when Apple TV go into Screen Saver mode, about 5 minutes after that it stops playing the Audio Stream and goes into Sleep mode.  I am using the Optical Out from the Apple TV to my receiver, the Apple TV is hard Wired to the Network, the IPAD is Wirelessly attached to the network (it continues to play the Audio Stream).  When the Apple TV is turned back on it resumes playing once I manual select it for output from the IPAD.  All device are on current releases of software.  I have no Video hooked up to the Apple TV.  How do I correct this?

    Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
    You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
    Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
    There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

  • Fan Speeds, and Mirror Raid with New Internal Hard Drive

    Regards,
    I recently installed and formatted a new hard drive in my PowerMac dual 2.3 ghz computer and I have a few questions.
    1. Now that there are two hard drives do I need to do anything to ensure that the fan on my computer can keep them cool? I think the fans I have in the hard drive bay is enough, but I do not know if they will automatically set themselves to run properly. I can monitor the fan speeds and temp from iStat pro, but do not remember what level the temperature was before installing the new one.
    2. Given that my new drive is a SeaDisc hard drive and the older one is a Western Digital, will this cause any problems in creating a mirrored RAID. I believe that both are 7200rpm drives, and my second hard drive is a little larger (I will just have unused space after making the RAID). I am concerned with the fact that these two drives are from two different manufactures. Will this cause problems or drastically slow down the reading and writing of data? Has anyone else experienced problems in making a mirrored RAID from two hard drives that are not exact matches, and even come from different manufacturers?
    Any advice will help.
    Thanks
    earpshmael

    Hi earpshmael;
    Generally when creating RAID arrays the more similar the drive the less problems you tend to have.
    The real question is exactly why do you want or need RAID?
    I think so many people seem to think that RAID will solve all of their problem. I hate to tell you the bad news but it will not.
    Generally there are to varieties of RAID available using the software RAID built into OS X which are 0 and 1. RAID 0 or stripling is generally for moving large file rapidly for applications like HD video. It usually doesn't help the OS. RAID 1 or mirroring is for protection from drive failure. It is not a valid backup solution.

  • My macbook boots up and only stays on for 30sec and goes into sleep mode

    My macbook boots up and only stays on for 30sec and goes into sleep mode! Any suggestions as to why this might be happening? Thanks....

    I assume you have checked your sleep settings in System Preferences>Energy saver
    I also assume this has just happened recently and spontaneously, not after installing any particular hardware or software or you would probably have mentioned it...if anything new has been added recently, obviously just remove it!
    It could be the battery - have your tried it just on mains? If it's a pre unibody MacBook try it without the battery at all. This could happen if you have a non-Apple (cheap Chinese) replacement battery.
    Try NVRAM, PRAM & SMC resets (Google if you don't know how)
    Try booting from the install media and repairing or reinstalling OS X. (Back up first!)
    Just out of interest if you boot from a DVD or go into Open Firmware or Boot Select modes, does it still sleep after 30 seconds or is it just in OS X?

  • Too high fan speeds? 15" late 2011 MPB

    Hi!
    I bought my new 15" MacBook Pro in the end of november, and it is therefore the late 2011 version.
    I have huge problems with the fans, though. Since day one, I have always thought that the computer was kind of loud, in comparision to my 2009 13" MacBook Pro, but just thought that since this new computer is more powerful, with the i7 CPU and everything, it was normal.
    Now, a little more than two months later, I have had enough. I have tried using Google to find an answer to this extremely annoying problem, but everyone is saying the same thing. Reset the SMC, reinstall OS X, install Fan Control apps, etc. I have tried everything, and nothing works as it should do.
    When in idle, with nothing but Finder on, the average temps and fan speeds are:
    CPU: 52°C
    CPU Heatsink: 47°C
    GPU: 45°C
    Left fan: 3700 RPM
    Right fan: 2600 RPM.
    I have tried using Fan Control apps (smcFanControl and Fan Control), resetting SMC, etc.
    If I look in the activity monitor, everything looks normal. Nothing that spikes out of the ordinary. Every time, it is the activity monitor app that has the highest percentage or CPU percentage.
    When having Safari and my mail client Sparrow on, and just casually browsing on the internet, the average temps and fan speeds are:
    CPU: 64°C
    CPU Heatsink: 60°C
    GPU: 49°C
    Left fan: 4300 RPM
    Right fan: 3200 RPM
    I would understand if I had these temps, fan speeds and noises if I were playing a graphic demanding game, or using Photoshop and Xcode.
    Computer spec:
    Intel Core i7 @ 2,4 Ghz
    8 GB RAM-memory
    AMD Radeon HD 6770M 1GB
    750 GB Hard Drive
    Late 2011
    I am writing here and explaining my problem since I am not sure if I should go to an Apple Store and let them deal with it. Maybe there's nothing wrong. Maybe these temps and fan speeds are normal, and then I just have to adjust. Otherwise, I know that there is something wrong, and I will let Apple fix it.
    Thank you in advance for any help!
    I appreciate it.
    Regards, Anton

    Agree with Ogelthorpe. You have some type of hardware problem.
    More then likely the heatsink that removes the heat from both the CPU and GPU is malfunctioning and has been from the first day.
    I'm running a 15" 2.2 i7 with 8GB RAM 120GB SSD 500GB 5400RPM HDD and right now my CPU is 41c GPU is 34c and I have Chrome, Lightroom, DNG converter, Thunderbird,  and Word open.
    Yes take it in and get it fixed.
    I would of taken it back the day after I bought it, compared it to the units siting on the floor of the store I bought it and then asked for a new one.

  • What are you using for Fan speed AND temp monitor?

    Thanks to Bosskiller, my rig seems to be running a bit stabler now!  Knock on wood.  Is there any program other than MSI's core center that monitor fan speed AND temp?   I used to use MBM but it's no longer being supported and CoreCenter doesn't seem all that popular here?

    Actually how accurate is the temp reading on HWMonitor for your MSI board?  One thing I noticed is that w/ Coretemeter the temp reading was around 48-50c on Rig#1 and almost 58-60c on Rig#2 (That's my HTPC w/ EXTREMELY tight spacings so still work in progress as far as cooling's concern!) but using HWMonitor I got 31c CONSISTENTLY on both rigs!     I'll love to think that I'm indeed running this cool but feeling the exhaust air, I think this 31c reading is not real...
