Fan on top speed

My computers fan has been on top speed (6100-6200 rpm) since a week ago. I tried to set the configuraiton to normal using shift-control-alternative-power button before starting up the computer again and I have also installed a fan speed controller (smcFancontrol) but nothing seems to help.
I dont use any hard graphic programs just iTunes and firefox and time to time openOffice. The fan doesnt tend to care. The temperature is about 35 degrees celcius or 97 fahrenheit.
Is there anything else I can do?
cheers

Welcome to Apple Discussions!
There are a couple of things you can check:
Run the extended version of the Apple Hardware Test and see if you get anything in the form of an error code. If a thermal sensor has failed, the fan will run all out by default.
Open Activity Monitor (in the Utilities folder in your Applications folder). Select "All Processes" in the upper preference pane and "CPU" on the bottom bar. Look for a hung up process which is hogging the CPU. Often printer processes will hang up like this, but it could be almost anything. A hung up process will also cause the fans to run all out. If you find such a process, highlight it and quit it.
Good luck!

  • Dc5850 cpu fan speeds to top speed sys then shutdown

    I have a Hewlett-Packard HP Compaq dc5850 Micro tower PC, now running windows 7 pro 64-bit. That was new in late 2008. Originally it came with vista 32-bit downgrade able to XP pro 32 bit, running on 2G RAM, and 160G C drive with a 2.30 gigahertz AMD Phenom 8600B Triple-Core processor. It also has ATI 3100 integrated graphics as well as integrated NIC at 1G and integrated High def audio. In the first few months I had the system, I upgraded memory by 4G and total Disc space by 500G by adding a D drive; then upgraded to windows 7 pro 64-bit.
    Overall, I have had a good experience with the PC but it has had problems while in its 3-year warranty. I did need to replace the C drive and later it original RAM devices. Yes HP did these replacements and swaps, under warranty; that meant I had 6G memory for a long time before the HP 2Gig failed out of warranty, leaving me with 4Gig now. Yes I have always had the Unit on an UPS; I even replaced the old UPS with a more powerful unit in late 2009 or early 2010 when the old UPS showed signs of failure. Now instead of serial based UPS connection it is USB.
    Over the last few months I have been getting blue-screen errors of all sorts. Ranging from video related errors, Memory faults, Disc read/write failures and processor flag errors too. After numerous repair disc runs or re-install of windows, the disc read write errors wore corrected by the HP drive sanitation utility disc repair/wipe after failing the extended test. The non video ram was tested by a bootable CD of memtest86 v4 running extended test as well as MS memory Diagnostic. Both run multiple times, both passed multiple times. I was able to find a CD based video diagnostic for ATI and the Video passed repeated stress test as well. Over Labor Day I conducted these test and re-installed windows 64-bit; on the following Monday windows informed me I needed to activate windows, so I verified the correct key and called to do so, successfully.
    With that background given here is the question. Recently over the last two or three months, for no apparent reason, mainly on boot the fan races to top speed and the system shuts down to protect itself. I researched this a little and found one cause to be inadequate airflow over the CPU to keep it cool; the recommendation made sense to vacuum with a computer vacuum and be sure airflow is not somehow obstructed. I am now thinking all these problems are related to the CPU temp sensor. Is it on the CPU fan or the motherboard, and can raising the fan speed in BIOS help prevent the problem, particularly if it on the motherboard.

    My pentium 4 3.0c stock Intel fan is 4.44 watts. Isn't the mobo designed for this?
    Also, can the sys fan header have the speed sensor activated by a bios fix or is it a hardware issue where it just does not exist? If hardware, seems strange since Corecell shows sys fan.

  • Cooling fan for iMac G5 - at top speed

    Even when only one program is open (like now with Firefox) the cooling fan is running at top speed.
    Is there any way to check on why and solve the problem?

    Hi jaygreenman,
    Just wanted to suggest, since you are not receiving much help here, that you may want to post your topic over in the iMac G5 usage forum:
    http://discussions.apple.com/forum.jspa?forumID=881
    Do a search there for "fan running full speed" or something similar and you'll find a lot of topics dealing with fan problems.
    Sorry that's all I can suggest but hope that helps some,

  • Installed SSD, now the fan is running at top speed

    Thought I would be brave and install an SSD in my new June 2010 Mac Mini. I have done this for an older Mac Mini, and my iMac, without any problems. It boots fine, but the fan is now constantly whirling at top speed (iStat shows it topping out at around 5K revs). The only temp sensor I removed was the one attached to the HDD, which I reattached to the SSD. I am pretty sure I got the cable attached to the sensor correctly connected back to the logic board. Can one mis-installed/mis-aligned temp sensor cause the fan to max out as it appears to be doing?

    Seems the answer to my question is yes. Opened up the case again and checked all the connectors, and found one of the temp sensors unrelated to the HDD/SSD had been bumped, and was slightly loose. Made sure all the connectors/connections I could see were properly seated, and now the fan is back to being basically silent (iStat shows it spinning at 1800 revs).

  • Macbook Pro 13" early-2011 Fans at high speed

    Hi guys,
    I hope you can solve this pussle for me.
    My Macbook Pro (13", early 2011, Core i5 @ 2.3) started to behave weird, its fan (only the exhaust one, since it's a 13" Macbook Pro with the Intel HD integrated graphics) is running at top speed (6200-6208 rpms) with no reason at all. No system processes consuming high CPU, just idling.
    There's a twist to this issue, though. It only does it when I open the lid more than 90 degrees. If I get it back the fan returns to normal functioning.
    What I did:
    checked the temperature sensor values, they are fine
    checked for crazy background tasks, there are none, CPU usage is at max 7%
    it does the same thing even in safe mode
    reset PRAM
    reset SMC
    reinstalled OS X (Lion). Updated to 10.7.4
    searched every discussion I could find on this matter
    The difference between this issue and others I encountered along the way is the lid opening thing.
    Does anyone know if getting the lid past the 90 degree mark triggers anything?
    The other theory I have is that there's some dust blocking the intake and when the lid is opened wide, the air is somewhat obstructed by the bottom of it.
    Any help is much appreciated.
    Thanks!

    You may have diagnosed the problem.
    (The other theory I have is that there's some dust blocking the intake  and when the lid is opened wide, the air is somewhat obstructed by the  bottom of it.)
    I would take off the bottom cover and see if there is any offending material.  If not, then the Apple store genius bar should be your next destination.

  • IMac G5 (no iSight) fans running full speed always

    Hi,
    The processor usage is relatively low (like 10%) but the fans are full speed at all times from the second the power comes on. I imagine there isa problem with the mother board? I've tried resetting all the SMC stuff, no effect.
    Any ideas?
    Is this something Apple Stores will charge to fix?
    Thanks

    It could be either faulty, leaking caps, or a failing power supply unit. Yes, Apple will charge since you are long out of warranty. You can open the machine and check the caps yourself, they look like little soda cans, and their tops should be perfectly flat and there should be no exudate.
    Let us know what you find,

  • Fans always max speed from boot

    Hi,
    my macbook pro unibody (15") has fans always on at maximum speed even. No matter the temperature of cpu or % of CPU activity (smcfan is of no use). Batteries drained in one hours...no use of a portable,
    After an hardware check it seems some temperature sensor were not working properly.
    I've got my logic board changed and.......fans keep running at top speed and now also keyboard backlight is gone....any suggestion...I'll ask to change the machine that is clearly faulty somewhere...
    Any hints from Apple?
    Ciao
    Nik

    Have you tried running the extended version of the Apple Hardware test? If you get an error code indicating the sensors, it may be that they were not properly plugged into the logic board following the logic board replacement. If the sensors are not sensing the temperature, the fans will run all out by default. If the sensors themselves are faulty, then replacing the logic board will not cure the problem.
    For the backlight, check in System preferences>Keyboard & Mouse> Keyboard and make sure the box is checked to illuminate the keyboard under low light conditions. If it is and the keyboard still does not light, the keyboard backlight flex cable may not have been well seated.
    Who did the repair? Apple or an AASP? If the latter, it may be worth trying someone different. It sounds like the logic board replacement may not have been done as carefully as it should have been.
    Good luck!

  • Qosimo X775-3DV78 - Fan no longer speeds up

    My lap top shut off not too long ago and now I noticed the fan no longer speeds up.
    Only the usual fan air take works but not the loud fan that speeds up.
    I fear, the laptop will only burn out eventually, any help?

    The laptop will shut down if it gets too hot before damage occurs. However, if the fan has failed, you'd probably want to have your laptop serviced.

  • Weird Mouse moving + Fan at FULL Speed + NO Power LED (Suddenly)

    After having a minor issue on Can't Wake Up from Sleep using Apple Remote Desktop 2.2 (previous post) .... Tonite I got another surprise !!
    Tonite, when I turned on my Mini (Intel), I noticed there are some weird movement on the Mouse pointer which happened before; however, since I used ARD as main control ... I will never notice such weird Mouse pointer behavior unless I plug-in and use an USB Mouse!
    How weird? Say, I move the USB mouse from Left to Right ... the pointer move and all a sudden ... it disappeared then resurfaced back at the Starting Point which is the place where I started moving it !?! Sometimes, the USB mouse simply not functioning when I move it, the on-screen cursor "blinks" rapidly !!
    ( BTW ... keyboard seems not functionally too at that moment ... reboot ... things resume normal ... )
    Already tried swap Keyboard, Mouse and different USB port too; no use!
    Reset PRAM = NO use.
    Reset PRAM then followed by PMU, now the Cooling Fan itself spins at FULL/Top Speed and I also noticed the Power LED Lite is now gone??!!
    USB Mouse problem .... still persist and happened randomly but only limited to physical connected mouse only. Using ARD? No problem ... even the pointer already freeze and blinking but it still under control !
    Good thing is, I am still able to use my Mini (Intel) .... its still working!!
    Any clue?
    Geez .. did I finally get a "Lemon?"
    Or should I bring it to service centre for this 7.5 days old Mac Mini (Intel) !
    ( p.s. don't worry there are neither Refund or Exchange in my country ... :< ... only way is to go dealing with Apple Service Centre.)

    just to continue...
    i plug in the power cord and the fans go full before i touch the ON button. no front light, no boot chime, no hard drive noise (though the fans may drown it out), no video after many minutes, pressing the power button does nothing. About the only thing this mac does is plug in and fans on full. Unplug, fans off.
    i held power in for ten seconds, i held power button for 5 seconds with power unplugged, i held power button in when plugging in power. Nothing.
    I even reseated the ram.

  • Mac Pro will not boot, revs fans at full speed

    Hi,
    I had my Mac Pro (2006 3.0 quad core) asleep, it woke itself up and didn't display video, instead revved the fans at full speed and did nothing, so I shut it down using the power button. When I turned it on, it did/does the same thing, no chime, no video to the displays, and I cant boot in safe mode or any other way, it wont even eject the DVD drive if I hold the mouse down.
    has anyone encountered this before?
    Any ideas?

    Give the SMC button a kick, hold it in for 5-10 seconds. Hard to see, but hidden by drive #4.
    Or try zapping PRAM/NVRAM first and see if that helps.

  • Spinning beach ball of death after crash with fans running full speed

    I recently put my machine to sleep - came in the next morning to find it running all fans at full speed and frozen. Did a hard reset (power button in for 5 seconds waited 15 secs and then power on. It rebooted after a long re-boot period. Since then it has slowed down. Many apps take an age to open. Many freeze and there is the infamous SBoD. I have rebuilt permissions, installed 10.5.8 combo, done a permission repair from a separate firewire disk, run onyx - which at time never ends and has to be aborted. Activity monitor shows no exceptional activity when the SBoD is running. I had significant issues until last December when i did a clean rebuild and installation of leopard and put all essential software in from clean install disks - all in all had a pristine machine which was working perfectly until the week before last when the full fan and freeze crash occurred. I notice that it speeded up after the 10.5.8 combo install and permission rebuild from external disk but gradually slows down and gets increasingly unstable requiring forced reboots more and more often. I have no hacks or other background processes other than Virus Barrier 6 which ran perfectly before the crash.

    As expected after running well at about 11:40 Mail slowed down and the SBoD started.

  • My AppleTV will not play anything over Air Play.  Every other function works perfectly, and my Internet/router are working at top speed.  I can watch HD Netflix and YouTube but nothing via my iTunes library on my MacBook or iPad.  All software is updated.

    Every other function works perfectly, and my Internet/router are working at top speed.  I can watch HD Netflix and YouTube but nothing via my iTunes library on my MacBook or iPad.  All software is updated.  The AppleTV will recognize that Air Play is trying to do it's thing, but with music files it sounds like they're skipping and video files just load endlessly. 

    I'm searching for an answer to almost the same exact problem, using almost the same exact hardware and software. Has an answer been found?
    The files that I'm trying to burn come from eMusic, and they are formatted mp3. Recently, (after the iTunes update to 9.2.3?,) they would not drag and drop from iTunes into Toast. From several different discussions I've tried working around this by dragging to the desktop first then dragging and dropping to Toast, going to Toast from a programmer's homemade help window, " iToons," and today, after talking with Apple support, going directly to Toast from my eMusic folder. Alas, all recordings do not perform like they use to. Sometimes they play and sometimes not. There is one I managed, that is listenable, but sometimes I have to put it in my car stereo over and over again as it gets ejected with an error code, sometimes, finally it takes it... Some of the recordings on other disks I've burned are not clean - they have white-noise sounds creeping in... I use to have none of these problems. One time as I was listening to a CD that managed to play, and it just stopped playing... Is there an answer out there to get back to how it use to be? Thanks for you help.

  • IMac Overheats & Fans Won't Speed up to Cool

    I have a 2007 iMac that for some reason the fans won't speed up above idle and so if it's put to heavy use eventually it will overheat and shutdown. It was a while before I had installed software that measured temperatures of devices or fan speeds inside the iMac and then determine what was happening and that indeed the iMac would shut off when the power supply got too hot.
    Then I found some of these apps that let you control the fan speed manually or customize the threshold and with some of these I was able to speed the fans up. The one I chose as the best was Derman's version of Fan Control, a control panel which is automatic and effectively keeps all the temperatures normal and has been my solution to the problem. Many people seem to like SmcFanControl for some reason but I don't because it's crude and  totally manual in setting the base fan speed which keeps the fan running higher than normal all the time but doesn't help much to cool if the iMac gets really hot unless you manually speed up the fan more.
    The whole thing baffles me. Why can this control panel speed up and control the fans just fine and effectively cool the iMac but left to it's default control it does nothing and allows the iMac to overheat? And has anyone had this problem and found a way to fix it?

    As you have already noted, the problem with SMCFanControl is that it only sets a higher minimum speed which leaves the user to have to manually ramp it up (or define a higher preset for various level tasks) when running something that will tax the CPU.  Cooler idle speeds will do little to extend the life of your computer.  My new Quad-Core i7 Mac Mini idles at a cool 110-115 degrees Fahrenheit (yes, that is COOL in computer terms to those that think it's hot because a day in Arizona at that temperature feels very hot). 
    Manual control is better than nothing if you know you're going to play a game or encode a file, but it stinks if you have a batch of files and you leave the room and it finishes and your fan keeps needlessly running at higher speeds (possibly for days if you left on a trip and left a list of videos to convert while you're gone).  I've left feedback on SMCFan's web site, but perhaps having an upper limit is beyond the author's capability?
    Derman's Fan Control has exactly the features needed, but sadly it hasn't been updated since 2007 as far as I can tell (Leopard Era) and thus may not be suitable for a newer Mac running Mountain Lion (the preference pane is also not 64-bit).  iMacs and Macbook Pros all have different fan setups for different equipment and my Mac Mini has its own case fan.  In my case, a Quad i7 will quickly reach 180+ degrees Fahrenheit or hotter when encoding with Handbrake at full speed.  Apple's own fan FINALLY kicks in beyond a smidgen at around 90C/190F, but it doesn't reach near full speed until it gets hotter yet (it seems content to let the CPUs roast at 90C/190F; I think Intel's automatic throttle is at 105C/221F, so perhaps Apple thinks that 90 is perfectly fine.  I'll admit the case isn't super hot or anything, but the concern should be the shelf life of the CPU and other components in the computer, not whether it will run at that temperture for weeks or months or even a year or two. 
    My PowerMac Digital Audio PPC tower (upgraded to 1.8GHz/1.5GB with dual 1.5TB Sata drives and used as a whole house audio/video server for over 6 years on nearly 24/7 and god knows how much before I bought it used in 2006) still works fine (case fan is starting to get a bit noisier, but still functions and the machine was on 24/7/365 for the most part!  It was built in 2001!  That's 11 years with no component failures and over 4 years 24/7 on the 1.5TB drives).  I'd like my new Mac Mini Quad i7 to last at least half that long.
    In short, there aren't many good solutions because no on has bothered (or at least bothered to update) a good fan control for the Mac.  I found a fan control program to run in Windows on my Macbook Pro and it has no configurable options, but automatically ramps at a very good set of default temperatures  and so it's just set to automatically run at startup and forget (I wish I could say the same about OSX; Apple's defaults seem to be set for quiet operation with little thought about longevity).
    I'd gladly pay a few bucks to have a good quality fan control program in OSX that is up-to-date, 64-bit and works fine with my new computer in Mountain Lion.  It's a shame I can't seem to find one to buy.

  • Lost 10Mb off my top speed. :(

    Afternoon all,
    Hope you're well.  Just wondering if someone can point me in the right direction with this one please, and also what information I would be best placed to provide to get to the bottom of this?
    I've noticed over the last 3-4 days that my once rock solid 45mb/16mb has now become 33mb/11mb, and whereas the (admittedly someone finger in the air) Speedtest.net test would fly up to the top speed and stay there solid as a rock, they now flip all over the place and produce less than consistent results.  33mb some times, 40s others, 12mb just a moment ago etc...
    I've tried the BT SpeedTester as well and get a similar result in the low 30s download.  I've also noticed my pings SpeedTest.Net have gone from 12-15ms to 30+ms...
    Something is definitely awry!
    Cheers in advance.
