Fan Runs strangely and Warcraft 3 and expansion run strangely...

I have been experiencing my MacBooks fan rev up and down and sometimes completely stop for maybe 5 seconds then just rev up again and slow down then get really loud then slow down etc. Is there any way to see how fast my fan is running? And if I need a new fan?
The Warcraft problem is when I am playing the game it will lag and then the sound will repeat multiple time and my cursor will "float". It makes my entire computer stop for a second then act funny for a second then go back to normal. My itunes music will repeat multiple times (like a record skips) also. Sometimes in the worst case the music will completely become just distorted but when i plug my headphones in and out it repairs it. Sometimes when this problem happens there will be a long tone coming from the speakers when this problem occurs I restart my computer.
Can anyone help this?? I know its very strange and quite annoying! So plleaassee help!

I updated to Lion 10.7.3 and started noticing my fans running on high all the time and my battery would drain 2-3x faster.  I was going to take my computer into an Apple store until I found this thread.  I did the SMC reset by shutting down my computer, plugging it in, and then pushing down shift+control+option while also pushing down the power button.  Nothing happens on the screen and the computer did not turn on.  I then released all the buttons at once after holding them down for 10 seconds. 
After that, I simply turned my computer back on and everything seems to be working fine.  The  fans are not blasting anymore.  I have a newer MacBook Pro where I can't access my batteries.  The SMC reset may differ for other types of laptops.

  • I have a dual 1.8 ghz pwer pc g5 and sometimes i put it in sleep mode and come home on my lunch break and the fan is running at full speed and the computer has frozen up...what is going on here?

    and sometimes i put it in sleep mode and come home on my lunch break and the fan is running at full speed and the computer has frozen up...what is going on here? is it a virus or has my computer been hijacked? it cant be good for the computer...anyone ever had this problem..?

    Your problem has been reported many times, but causes are as varied as individuals.
    Can we assume that a hard shutdown allows a normal restart?
    Can I assume that you have used Disk Utility from your OS X install disc to repair the hard drive directory? The freezes and hard shutdowns require that the drive be repaired (not permissions) or soon the machine won't boot at all.
    If the root issue is software related, in Console (the application) under Logs, there should be loggings around the time of sleep and logs that tell you what process went wild and froze the machine.
    Network activity is also a common casue.
    Other info:

    If hardware related, such as an external drive, other USB device (Wacom tablet) or USB PCI card, ejecting, disconnecting, removing, or in the case of the Wacom, updating drivers, are all potential remedies.

  • Fan running at full speed and all the time!

    Hi,
    I was wondering what could be the reason for my fan running on full speed at all times?
    It is pretty annoying especially when I am in a quiet room. This just started happening this morning and I thought it was just going to stop but it didn't so I restarted my MacBook and shut it down also and still no luck.
    Oh...
    My battery meter only says 1:45 after I just took it off the charger when it said it was fully charged and I had the green light on my charger.
    What could be the reasons for these two things?
    Thanks,
    Sam

    I reset the PMU and the fan is still going at full blast right when the MacBook starts up.
    Will I know that the PMU is reset or will it just fix the problem if it is?
    Does anyone know a solution?
    The computer is running fine but it's just the fan that is really loud and going at full speed and the battery life is extremely short for some reason.

  • Fan Runs all the time- and Loud

    Since last night, the fan on my G5 hs been running constantly and loudly. It never did this before. The only difference between then and now is I run Software Update which updated iPhotos and QuickTime. It's driving me crazy! Anyone know how to stop it? Even when I restart, the fans never shut down. When I shut down they stop until I restart. I tried resetting the SMU but that didn't help.
    Thanks.

    Which model iMac do you have (how to identify your iMac)?
    Have you repaired Permissions?

  • Just updated to 10.7.2 and the fan on my 2011 mba wont stop running.

    I updated my 2011 Macbook Air to 10.7.2, and now the machine is really hot and the fan won't stop running. Any idea how I can make this stop?

    There is likely a program or process that is taking up most of the CPU.  If you open Activity Monitor and sort by the % CPU column that will tell you which process it is.  If its a program that don't need then you can simple quit it. If its something you don't recognize or something that you need to have running then report back and then the next course of action can be figured out.
    I had this problem with the Dock.  Deleting the dock preference file then restarting the Dock process addressed it. Your situation may be different.

  • HP G42 Fan Running in High Speed and Noisy

    I had a HP G42 i5 notebook. Recently I send my notebook for repair due to the graphic card problem. I encountered that the fan speed is running in high speed mode after I the repair. I asked the incharge and he told me that they had did the cleaning on the notebook, so the fan will run in high speed and making noise. I did told that person, it was silence before repair and the fan will only run in high speed mode when the notebook's got heat up. But now it's got into the high speed mode even during startup time.
    So I would like to get some advice or comment on this. Is it normal that the notebook's fan speed is running in high speed and noisy since startup? Thanks in advance.

    Hi Richard-G,
    I'm sorry for the delay in my reply, as I have been out of the office since last Thur.  The instructions would have been the same for your notebook, but not the same BIOS.
    This document will guide you through updating your BIOS if you wish.  Since the noise is reduced once Windows begins, I would not worry too much about this.
    Good luck!

  • CPU running hot and fans maxed out while no programs are running

    My 2007 MacBook Pro 3,1 suddenly started running hot (CPU-85°C) and the fans are ramping up to 6000rpm for no apparent reason. Nothing but Firefox running. I just downloaded a new Security update. Is anyone else having these issues? Any fixes out there? Should I be concerned? Thanks.

    There are a couple of things to try.
    First, I always repair permissions before and after adding anything from Software Update. May be overkill but I've never had any issues with updates on any of the family's eight OSX computers.
    Second, are you running any anti-virus software other than ClamXav? Most commercial packages create more Mac trouble than they prevent.
    Third, use Activity Monitor (AM) to check for runaway background processes. IMPORTANT: to catch the culprits, you have to change Activity Monitor's default setting of "My Processes" to "All Processes." Otherwise, most of the likely suspects are going to fly under the radar. Also quit any apps you have launched. Click AM's "%CPU" column to sort by how much of the processor each background process is using. Let it run about a minute and observe what shows as the largest users. In either Leopard of Snow Leopard, no background process should show over about 5 percent. If anything is grabbing a lot of cycles, post the process name here and we can help you figure out what it is and how it can be corralled.

    I suspect you didn't reset it right.
    Turn off the machine, let it charge up and then try the SMC reset again.

  • Fans run at 6000RPM constantly and Function keys are misassigned

    OK here's the story: I've got a 17" Core 2 Duo MBP that I replaced the top case (keeping the original keyboard) and hard drive in. Now the fans run at a constant 6000 RPM despite what I have Fan Control tell them to do. In addition, the function keys are misassigned - the keyboard is labeled with volume control on f3-f6 and keyboard brightness at f8-f10, but f10-f12 actually control volume and f5 and f6 control the screen brightness (it appears it still thinks I have the 110 key USB KB plugged in since it's following that layout).
    I've tried resetting the SMC and applying the SMC firmware update with no luck (the firmware updater tells me I don't need it and I can't find a way to force it). There are no processes hogging CPU, and I've disabled indexing just to be sure. The fans will run at 2700 or so for the first few minutes, but as soon as the temp hits about 104F they go max and don't slow down until I shut it down or put it to sleep. I'm using a drive image from a black MacBook so I suspect my OS install is confused about what hardware is actually present, but before I do a clean wipe and restore I'd like to know if anyone has any other ideas. Thanks!

    Welcome to Apple Discussions
    The fans run at maximum if either a) the cable has been left off the temperature sensor or b) the sensor is bust - I'd guess you didn't remake the connection or it's come off during re-assembly.
    +a drive image from a black MacBook+
    That's a mistake, you should only install and use the OS that came on the install DVD with your MacBook Pro, there are significant differences in the software ...

  • Often I will leave my office and return to find the fan running at max speed and the computer is unresponsive

    I also have a MacPro3,1 (2009) I believe and just started experiencing similar issues as described here.
    I have scheduled sleep and start cycles and often I will leave my office and return to find the fan running at max speed and the computer is unresponsive or I find the computer booted in to disk utility mode.
    I also often loose ethernet connectivity and have to try renewing DHCP lease several times before it will finally work.
    Has anyone found solutions for this. I have looked at the console errors right before shutdown and don't really see anything fishy. Here are the last couple of lines before it looks like it shutdown.

    Mac Pro early 2009 is Mac Pro4,1, anyway, I think you need to boot into recovery mode, launch Disk Utility, then select startup volume and run repair disk.
    Xcode is the latest one, by the way?

  • Macbook Pro fans constantly running, Safari hangs up and/or crashes often.

    My 2012 Macbook Pro (10.9.2, 2 GHz Intel Core i7, 4 GB Memory) has been acting up a lot lately. The fans are constantly running even if major apps (mail, safari, itunes, messages, etc.) are closed. Safari, in particular, has been hanging up and/or crashing recently for no real apparent reason. My battery has been draining out faster than usual.  I've always tried to be very cognizant to the health of my computers and phones and try to limit the amount of apps and files I download, sites I visit, etc. I've already done Verify Disk and Verify Disk Permissions in Disk Utility, reset Safari numerous times, disabled all extensions, removed unnecessary apps, and altered settings in Energy Saver, all to no avail. I'm a grad student so I only use my laptop for Safari and Microsoft Word and put it to sleep when not in use as often as possible. Also, my battery was at 56% about 23 minutes ago and is now at 38%.
    Below is a list of the processes using the most memory in Activity Monitor:
    kernel_task                                   429.4 MB
    Safari Web Content                      127.7 MB
    com.apple.IconServicesAgent     122.8 MB

    have you tried resetting your MacBook Pro’s System Management Controller?

  • I have a Macbook Pro early 2011 running 10.7.5, does anyone know why it sounds like the fans are spinning really fast and loud. It's not like I'm using many applications at one time. Thank you.

    Trying to see why the fans are spinning real loud and fast. I dont have a nearby Apple store to take it to and Bestbuy wants to overcharge you for a bunch of uncertified geek squad employees working on them. Any help? Thanks in advance.

  • I have a 3rd generation iPad running iOS7.0.2, and since updating to iOS7, it will not mirror to an AppleTV.  The devices will connect, but the video monitors show only a blank screen.  The AppleTV's work fine with various other iOS & OSX devices. Ideas?

    I have three AppleTV's where I work.  I have two at home.  I have an iPhone 4S running iOS7.0.2 which mirrors smoothly via AirPlay.  I have a 2011 MacBook Pro and a 2011 iMac, both running Mountain Lion, both of which mirror smoothly through AirPlay.  I have a 3rd generation iPad running iOS7.0.2, and since updating to iOS7, it will not mirror.  The iPad will connect to the AppleTV, but the TV's and projectors only show a black screen when connected: the iPad screen looks as it should, except that the transitions become jumpy when connected via AirPlay.  This is true on both networks: at home and at work.  Another gentleman using the network where I work has the most recent iPad, also running iOS7.0.2, and he is having the same problem.  I have tried to "Reset All Settings."  I have tried to "Restore."  Does anyone have any suggestions?  Has anyone else experience difficulty mirroring the iPad through AirPlay since the release of iOS7.0.2?

    No problems exists with the router (on either network described above) or the multiple AppleTV's which are able to mirror multiple other OSX &amp; iOS devices seamlessly. The problem is strictly with the iPad and iOS7.

    This is an iOS 7 AirPlay mirroring bug...
    To make matters worse, the iPad automatically drops its mirroring session 45 seconds after it auto-locks.
    3-4 mirroring sessions is all it takes for the iPad mirroring to freeze up.
    After this happens, mirroring to an Apple TV only projects a blank screen.
    Once the mirroring is hung, the only way to fix it is to restart the iPad.
    Apple please fix this iOS 7 issue!

  • [FIXED] Compiz runs only with emerald and crashes with metacity

    Hey,
    I currently try to use a metacity theme and have compiz enabled but apparently that's something compiz doesn't really like.
    One think i noticed in fusion-icon is that the entire metacity option under: "Select Window Devorator" is just not there.. (or was that always the case?)
    Oke, things i have done so far:
    - Search this forum (obviously) nothing found with a solution
    - Searched the wiki (same results)
    - in gconf-editor /desktop/gnome/session/required_components/windowmanager set to compiz (like said in the Compiz wiki page on archlinux.org
    - disabled metacity as compositing manager (tried with enabled as well but the same results)
    - right now i have the compiz bash script from ubuntu (tweaked a little) and that starts up compiz just fine but not with metacity
    And incase you want the script:

    That's it so far.

    I hope someone can help me here,

    Wait, what, I thought metacity isn't as window decorator, it is a window manager, right? I don't really get what you're trying to do... maybe install compiz-decorator-gtk and use it instead of emerald?
    edit: aaah, yes, I think you're missing compiz-decorator-gtk, try that, look at fusion icon "window decorator" option again.
    Strange.. i was under the impression that pacman -S compiz-fusion would install GTK and QT decorators... guess not.
    This issue is fixed now. Running metacity decorations now WITH compiz.

    Sorry if i wasn't more clear but was that response needed?No it wasn't needed, but I'm not the one asking for help so I have the luxury of not worrying too much about it. It's extremely frustrating trying to drag relevant information out of someone, and makes one less inclined to bother.
    Anyways, there's still nothing in this thread that actually explicitly says "there is a file called VolcanoApp.java in the directory where I'm running javac from" and I really can't be bothered banging my head against the wall any longer. You've made a silly mistake, or a false assumption. We all do it from time to time. My advice is, take a break, go for a walk and re-visit this in a while. You'll probably spot the mistake right away.
