IMac fan will not shut off. Screen discoloration. Mac disappointment.

I have an iMac (3.06 24") about a year old. About 2 weeks ago the fan(s) started running all the time. This had happened once before about 6 months ago. An SMC reset and PRAM reset "fixed" it that time. This time though all attempts did nothing. The iStat widget showed normal temps except for the ambient temp which read a ridiculous 259 degrees. I did a Apple Hardware test and got an error code for the temp sensor. Took it to apple store 5 days ago. They said they would replace the temp sensor on HD and since they noticed screen discoloration at bottom left of screen they would replace that too while they were at it.
Today they called to tell me the temp sensor did not fix it and they were replacing the logic board. This has turned into a "thing."
I am very thankful that it happened 13 days before my apple care expired. (whew!)
I am glad that Apple is fixing it.
I am disappointed however that this happened at all. I never had any problems with my Macs in 10 years and now it seems the last two major mac purchases have been problematic. My macbook pro has performed poorly. latch broken. casing bent. battery awful etc. And now this iMac thing.
I post this for a few reasons.
1. To help anyone that has a fan issue and let them know that it could be potentially serious so stay on top of these little things.
2. Apple care. Apple care. Apple care.
3. I'm curious if others have issues with their similar model imacs. Did the logic board fix stick?
4. Is there currently ANY machine in the Mac line up that is a solid workhouse with few, if any, problems. Please don't let this turn into a "If you had a PC it would be worse" thread. I know that. I'm already a believer. I just hold apple to a higher standard.

I've been repairing electronic equipment for over 40 years and you are always going to run into components breaking down; that's what warranties are for. I always advise buying AppleCare if you plan on keeping your Apple product over a year. It also adds to the resale value if and when you sell it under 3-years old. Tip: You can buy an AppleCare plan for an iMac for about 1/2 the cost of retail on eBay. I buy all my plans there and never had a problem.

  • IMac 27" (mid 2010) FAN WILL NOT SHUT OFF

    Hey, I'm not sure if this topic has been brought up in the past or not, but I'm having major problems with my iMac and the fan never turning off. From the moment I turn the computer on the fan is running at full speed.
    Computer has plenty of ventilation - running off of a surge protected power bar - almost never have more than 2 or 3 applications running at one time. The fan will run at full speed with no applications running as well.
    I have taken the computer back to the company I purchased it from so their tech department could review it, they said there's nothing wrong...
    I reviewed the article on apple's website regarding fan issues and resetting the SMC. I followed the exact procedure noted to reset the SMC and it did not fix the issue.
    Has anyone else had this issue? What did you do to fix it? My computer is less than 2 months old has nothing on it except for iTunes and a few scanned fax documents...
    Please Help!!!

    Rik84,
    Welcome to Apple Support Discussions.
    Is this how you did the SMC reset, either way please re-do it and a PRAM reset as follows:
    _SMC RESET_
    • Shut down the computer.
    • Unplug the computer's power cord and all other cords.
    • 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.
    • Release the keys.
    Regards,
    Roger

  • My ipod touch will not shut off. lock up

    My ipod touch will not shut off. It is just a black screen with the time dial turning. It does not do anything. How can I get it to do something?

    Try:
    - iOS: Not responding or does not turn on
    - Also try DFU mode after try recovery mode
    How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try on another computer          
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • MSI z77A-G43 - After Shutdown - Fans will not turn off

    Just installed a new MSI Z77A-G43 Motherboard for my husband since his old motherboard died. The one thing I've noticed though is that the fans will not turn off after I do a shutdown and I'd have to do a manual shut down instead. Any ideas what could be happening? Also it will randomly restart when not shutdown completely with the fans still on.
    Here are the specs of the PC.
    MOBO: Z77A-G43
    Processor: Intel i5 - 2500k Quad Core
    Video Card: Geforce - GT 610
    Ram: 8 Gigs
    Hard Drive - 128gb ssd and 1.5 tb hdd
    It's really barebones since I'm trying to just get it to run then get it back to normal working order with the next pay check
    EDIT!!!!::
    Forgot OS is Window 7 Ultimate X64

    If you are sure that your CPU is seated properly and that the PWM fan connector is seated correctly, then you may want to test with another known working PSU. I am not saying that your PSU is faulty, but before exhanging the board, I would definitely test that as well.
    EDIT: Just a question, did you disconnect the power switch and the other front panel connectors of your case and started the PC by shorting the Power switch [pins 6 and 8 on JFP 1]with a screw driver tip ? The remote possibility exits that the cables may have been connected incorrectly or may have a short.

    Ipod classic will not shut off. Have held menu/select until apple logo appears, no change

    Menu/Select is to reset the device, not turn it off. You need to press and hold the Play/Pause button until the display turns off.  Then activate the hold switch.

    You should try taking it to the Apple Store and asking for a replacement.

        Hello Four_Soups,
    That is incredibly strange! I'm so sorry your son is having this issue.  I will be delighted to check into this and see what we can do.
    I checked my resources and I didn't see any other recorded reports of this same issue.  I truly appreciate you trying to reboot the phone as I would have suggested this as well.
    Since you've already completed that step, I would ensure all of his personal information is backed up such as contacts and media (pictures, etc) and reset his phone:
