My fan is on ALL the time. Any ideas?

Hi Appleheads,
My Macbooks fan just keeps on running. I am using Safari, iTunes, Mail and sometimes Firefox. I don't use any big apps so not sure why it's going mental. It has been doing this for the past 2 or 3 weeks. It's doing my nut in.
I've already gone through disk utility and repaired the permissions. Could it be something to do with the Widgets o the dashboard?
Also because my fans running so long, it's eating up the ole battery. It's dropped from 12 to 4% in about 2 mintues.
Can you help?

Glad to hear your fans have settled down. As far as temperatures go, I use Celcius and mine is usually in the 46-60 area. When I switched to fahrenheit, it says 100-120 and the fan is only running at 1500rpm. This is totally normal. Your fan actually runs constantly at around 1500rpm, it is just so quiet your can't really hear it unless your hold your ear to it. If you are truly running at 86 degrees fahrenheit, you are fine, but having the guys at the Apple Store look at it isn't a bad idea. And you get the chance to talk to the Specialists there too. If you end up having to wait a little for the Genius Bar, take advantage of the Specialists while your waiting for your name to be called. Sometimes the stores are pretty crowded, but I find they enjoy answering questions for anyone that is willing to listen and learn.
Good Luck.
Adam
PS... I just thought of something I would like to share.
With all the new updates coming out lately, I would like to suggest to all new Mac/Apple users this word of advice...
Only install 1 update at a time. use your mac for a couple days to determine if you are having any problems before going to the next update. Too many new users are running into issues after installing multiple Updates at a time and I figured this would be sound advice.

  • My Mac book pro has all the sudden started running slow and freezing up all the time , any ideas why or what to do

    Hello ,
    I am not very good with tech things , I have a Mac Book Pro and have had it for almost two years with no problems. Now for the past week or so it has started running extremely slow and freezing up all the time. I am not really sure what is going on but is there any advice on something to do or any idea what could be wrong.

    My MacBook Pro is running very slow.

  • My fan is on all the time - possible overheating; software cause?

    I’ve got a 17” G4 powerbook running Panther (OS10.3.9). It has been doing great but lately I’m noticing that the fan is running all the time. The thing sits on one of those aluminum wedge-shaped platforms (for max. air flow) on my desk and the room isn’t very hot. I have a temp monitor running on it and it says 52 C, even though the machine isn’t doing anything computational. I’ve also gotten one warning from the SMART sensor on the internal drive about a possible future failure due to high heat. I do know that my disk space is running low (2 Gigs when I boot up, which slowly disappears as I work). Is there anything software-related that can be the cause of this or do I definitely need to send it to a repair shop? If the latter, then where do I send it? My AppleCare is surely expired now… Is an Apple store my best bet, or an independent repair place, or what?
    Machine Model: PowerBook G4 17"
    CPU Type: PowerPC G4 (1.1)
    Number Of CPUs: 1
    CPU Speed: 1.33 GHz
    L2 Cache (per CPU): 512 KB
    Memory: 1.5 GB
    Bus Speed: 167 MHz
    Boot ROM Version: 4.7.1f1
    Serial Number: V7344967P21
    Memory:
    SODIMM0/J20STANDARD:

    SODIMM1/J23REVERSED:
    Size: 512 MB
    Type: DDR SDRAM
    Speed: PC2700U-25330

    I have a very similar problem. My G4 has been running great since I picked it up in January. But, in the last couple days my fan has been running real loud and the machine in general has been hot. Today was watching some youtube and my machine started to freeze up all togeather (a problem I've never had before) as the fan started sound extra loud. As I tried to power down my machine the fan started to make a more grinding type of sound and cause my whole laptop to vibrate. I just really want to know the best coarse of action here. Should I take my mahine to my mac people and have them replace the fan? Is this a common problem? What is this a cronic problem that is a symtom of somthing more ominoius?
    Thanks for you're help!!!

  • I want my fan to run all the time on power adapter, any guru know how?

    After buring out one hard drive, and getting tired of hauling a mini-fan and 1/2" foot spacers around with me between motels, I want a way to force the powerbook fan to run at full speed all-the-time when the powerbook is connected to a/the power adapter. Anybody out there know of a "patch" / "script" / "shell add-on" that will do this on 10.2.x?

    Trust me, you don't want to do this. That's not how they are designed to run. If your machine is overheating, consider this article:
    http://docs.info.apple.com/article.html?artnum=30612
    And perhaps a notebook cooler, like this one by Antec. And when get back home, run the hardware test that came with your machine:
    http://docs.info.apple.com/article.html?artnum=86178
    If your machine is under AppleCare, I would take it in for service if any issues are detected.
    Also note if your battery is under the battery exchange program:

  • MacBook Retina 13 fan goes up all the time and wlan crashes every few minutes

    Hello,
    I've got a MacBook Retina 13" Haswell edition and as soon I open any kind of app or if I just idle at the desktop the fan goes up to 100% and the temperature of the CPU goes over 90celsius all the time.
    Also my wifi connection drops all the time im not using my thunderbolt bridge which is super annoying, it can only be fixed by tuning the wifi on and off and after 10 minutes it disconnects again.
    is there any way to fix it?

    Backup your data or Home folder. Boot from your Snow Leopard installer disc. Select your language and click on the Continue button. Wait for the menubar to appear then select Disk Utility from the Utilities menu. Select your hard drive from the DU sidebar, click on the Erase tab in the DU main window. Set the format type to Mac OS Extended, Journaled, then click on the Erase button. When the process is finished quit DU and return to the installer. Complete the installation.
    After you have reinstalled OS X you can restore your data from the backup.

  • Powerbook fan turned on all the time?

    I just had my logic board replaced and since I've had it back, the fan run constantly. All the time, non-stop. The temperature sensors read the processor temperature at ambient (24-26C) and the hard drive at 40C.
    Is there a setting or something I can tweak rather than send it all the way back to apple? I lost a whole week of work when it was in repair and dread having to send it in again...

    I'm not aware of any setting that will turn the fans on or off, beyond the Apple hardware test that tests if they are working. Although you're not keen on returning the machine to Apple, they mucked something up and need to make it right.
    That said, you can try resetting the Power Mangement Unit by following directions at http://docs.info.apple.com/article.html?artnum=14449

  • New MBP seems to run hot & fan runs almost all the time

    I've had my MBP for just about a week now. It's the new, 15", 2.2 GHz model. It's great, but I notice that it runs hotter than my Powerbook G4 did and the fan is almost always on. It's presently sitting on a wooden topped table. My house is not AC-ed, but the air temp is about 70 F/21 C today. Seems to run hot in my AC-ed faculty office too, when I am there. What is "normal" for this machine. TIA.

    David,
    Ditto what Ned says. To be sure, 80 C is not too hot (it is the temp that the MBP is designed to maintain as a working maximum), but that you are experiencing this temp at all times indicates that something is pushing the processor at all times.
    That is not normal. As has been suggested, have a look at Activity Monitor. If you are not doing anything of any consequence at the time, your CPU usage should be very, very low, and processes that you see using CPU intermittently (there will be many of these processes) should only use a small percentage when they use any at all.

  • Fan is on all the time since I replaced the HD

    I just replaced my stock macbook HD with a Hitachi 160GB 5600RPM HD and ever since I have noticed that the fan is always on. Right now, for example, CPU A is 36C and the fan is running at 1495. When I first started the machine this morning the temperatures were in the teens but the fans were running anyway.
    I backed my machine up, replaced the HD, re-installed the OS from the disks, used migration assistant to restore data from the backup, and then let the software update do it's job.
    Any ideas what is going on? I think I'll swap in my old drive and see if it behaves any differently.
    (40C now, still 1494)
    Ben

    I switched back to my old drive (ridiculously easy to do in a macbook, thanks apple!) and started it up but couldn't hear the fan. When I checked iStat pro, however, it was just as you said - the fan was running at about 1500 rpm. I just couldn't hear it. Switching back to the new drive, I could hear the "fan" again. I really does not sound like the drive, but what else could it be? iStat is telling me the fan is running at 1500 rpm just as before so the only new sound could be the drive itself. Nothing horrible, just noticeable. Certainly something I'll live with to gain the extra 100GB.
    Before I put this to bed I want to figure out a way to put the drive to sleep and see what the machine sounds like then (because it really really sounds like a fan to me - though I can hear it best coming right from where the drive is located so... it all points to a much louder drive).

  • HP Envy Fan Suddenly Runs All the Time

    A few weeks ago, I sent my HP ENVY 15t-j000 Quad Edition Notebook PC (product number E4T17AV) to HP because my trackpad was especially stiff, squeaky, and unpleasant to use. After they sent it back, my hardrive was wiped. I restored all of my files, and despite some permissions issues, that has gone smoothly. However, ever since I've begun using my Envy again, the fan runs constantly and the computer is always warm. I've had it for about a year with no serious issues, and the fan never ran like this before I got my computer back from HP. The fan even runs when the computer starts up and there are no programs open. This is obviously a little annoying. Does anyone have some suggestions?
    Miranda

    Hello @MirandaSnow ,
    Welcome back to the HP Forums!
    I understand after having your notebook services the fan constantly runs and is getting warm.
    Can you tell me if you are using any software to manage the fan speeds and what operating system you are using? To see which version of Windows you are using click here: Which Windows operating system am I running?
    Here's 2 documents to get you started: Fan is Noisy and Spins Constantly, PC is Warmer than Normal and Reducing Heat Inside the PC to Prevent Overheating
    You can find a detailed guide to disassemble the notebook for better cleaning here: Maintenance and Service Guide. Please do not remove the fan/heat sink unless you have new thermal paste to apply.
    Let me know if either of these help.

  • GT60 0NC, no GPU and fan at 100% all the time

    Hello.
    Recently after many tries to solve nvlddmkm.sys problems I've got final crash. After which my OS could not see my GPU and fan was spinning at full speed. It was after underclocking shader clock from 1240MHz to 1200MHz and opening a game. The screen froze and at the bottom of the it, there was black belt through the screen with RGB colours dots in random locations. Now after full reinstall of the OS from win7 64bit to win8.1 64bit, this all still persist.
    Any ideas would be good, as I could not see nor find any solution to this.
    My current config is:
    -MSI laptop GT60 0NC
    -NVIDIA GPU GeForce GTX 670M
    -Intel Core i7-3630QM
    -Windows 8.1 Pro N 64bit

    So to settle the fan down I would have to disable dGPU. Not just unplug it but disable it. And to do this I would probably need unlocked BIOS. Correct me if I am wrong, if not I would appreciate any leads how to do this.
    And if my dGPU is broken I can at least try the oven. And question about further actions, can i access mini PCI-e in MSI GT60 0NC in any way? To try connecting external GPU via EXP GDC Beast Laptop External Independent Video Card Dock. I do have GTX 460 from my old PC so I am just wondering.

    The kernel is using excessive processor cycles. Below are some possible causes for the condition.
    Throttling
    When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
    ☞ a buildup of dust on the logic board
    ☞ high ambient temperature
    ☞ a worn-out or faulty battery in a portable
    ☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
    Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
    If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models. CPU usage should drop when charging is complete.
    Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
    If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
    Installed software
    User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
    Corrupt NVRAM or SMC data
    Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
    External display
    Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.
