MBP Fans speed up during minor operations

Hi everyone,
Something has happened to my MBP over the last few weeks. It always has been the case that whenever I have my MBP do a heavy operation (compressing HD video, for example) the fan kicks up to 6000rpm, as it should when all the computer's available resources are going to a heavy operation like that.
But now, I can just be browsing through a couple of different Firefox windows or have a few programs like Word or Excel open and the fan will kick up to 6000rpm again. And it won't quit unless I do something about it. I'll either have to close it up for a little while, or take it to the basement in my office where it's about as cool as a fridge. When I take it downstairs and set it on a cool surface, within about two minutes the fans have dropped back to 2000rpm.
Here are my readouts I get from when I have the MBP on my desk and it's up at 6000rpm versus after I've had it downstairs for a few minutes:
Before:
CPU: User 16% System 4% Nice: 0% Idle: 80%
Memory: Wired: 215MB Active: 538MB Inactive: 1.01GB Free: 1.25GB
Temps: HD Macintosh: 108F CPU A: 133F Enclosure Base: 99F GPU: 124F GPU Heatsink: 130F Heatsink A: 124F Heatsink B: 113F Mem Bank A1: 140F
Right Fan: 6001rpm
Left Fan: 5994rpm
After:
CPU: User 8% System 5% Nice: 0% Idle: 87%
Memory: Wired: 215MB Active: 539MB Inactive: 1.02GB Free: 1.25GB
Temps: HD Macintosh: 108F CPU A: 131F Enclosure Base: 97F GPU: 117F GPU Heatsink: 121F Heatsink A: 119F Heatsink B: 101F Mem Bank A1: 133F
Right Fan: 1994rpm
Left Fan: 2003rpm
And just now as I was writing this post, the numbers went back up to where they were before I brought down to the cool room. Any ideas?

That is always a problem--you need your Mac so you can't ship it off for repair because you can't do without it.
I think that Apple has some sort of a program where you pay an annual fee, and as one of the benefits, you can get a loaner if your Mac has to go off for repair. This may be something to consider.
Be sure and at least get a case number to document all the problems that are covered by your warranty, and be sure and send it off before the warranty expires. I still think the genius bar could run the AHT to see if you have a sensor problem or not. If you do, it is something that needs to be fixed at some point.
Good luck!

  • IMac 27, i5/i7 - Fan speed / temperatures during gaming?

    Hi all!
    This is my first post in this forum. I have searched a lot in the internet, but I have not found any reliable information on this topic.
    I currently have a MBP (see signature) and I am really happy with it. However, each time I am playing a game (just casually), the fans accelerate to 6200 rpm within a few minutes which is really annoying (= very loud, high frequency noise). Typical games are Sims3 as well as the Steam games TF2, Portal, and Torchlight. Furthermore, I am playing games like Black&White2, Bioshock or Chess using Parallels 5/Win XP.
    I am now looking for an additional desktop computer - and I am loving the idea of buying an iMac i5. However, I would really hate to hear this loud fan noise again... (the alternative would be a Dell XPS 7100, but I really love OS X after 20+ years using Windows).
    Thus, I am looking for reliable data (fans rpm, cpu/gpu temperature) during gaming (under steam os x, parallels, and boot camp). Also any experience on long-term reliability of iMacs used for gaming is appreciated.
    Thank you very much in advance!
    P.S.: Hope my english is not too bad, since I am not a native speaker...

    It's a simple match - the more power your computer uses, the hotter it gets, and the faster and louder the fans. The graphics card and CPU are the most power-hungry parts, and are used at a high percentage during gaming.
    That said, my current iMac is the i5 (27", 4850) and it doesn't spin up the fans at all playing Torchlight at full native resolution. It does start whirring a little playing Bioshock/Portal/HL2, but not so loudly - the fan speeds go from 1100 (normal, nearly silent) to 1450 or so.
    Temperatures I've not followed - but they don't actually matter, just the noise that is made to keep them under control.
    In Boot Camp, much the same - although I don't have a fan-speed monitor for Windows, again HL2 would just slightly speed up the fans.
    But! I would suggest waiting a short while, it's 10 months since the iMac range was last refreshed so it could be just about time for them to be updated.
    ps Your english is perfect, I would never have guessed you were not a native speaker.

  • MBP Fan Speed/Temp and one extra problem.

    My 17" MBP fan is almost constantly running at the max speed (6000 rpm). The temp is at 75 C as well. Since i'm in school the loud fan speed it very annoying and I would like to know if I have a problem with either my temp sensors, logic board or fans.
    My other problem is that I get two error messages saying that a usb port is drawing too much power and will be deactivated. I have 3 usb ports my two left ones do not work and only my right one functions.
    Any help would be great.
    ~ Justin

    One thing to do is to run the extended version of the Apple Hardware Test and see if anything shows up in the form of an error code. If you get an error code with "SNS" in it, that would indicate that a thermal sensor is either not working or possibly not plugged in. If a sensor is not working, the fans will run all out by default.
    Another thing to check is Activity Monitor for an out of control process which is hogging the CPU. Open Activity Monitor and select "All Processes" at the top and "CPU" on the bottom bar. Then peruse the CPU column for any process hat is running amok. If you find one, then highlight it and quit it and see if that takes care of the problem. Sometimes a printer process will hang up and hog the CPU, but it could actually be almost anything.
    Regarding the USB ports, you can try to reset them. Power down and remove both the power adaptor and the battery for 15-20 minutes. Then power up again and see if they work. If your USB devices are drawing too much power from your USB ports, you may want to try a powered USB hub.
    Good luck!

  • Is this normal fans speeds for MacBook Pros? See videos of my MBP in action

    I can't figure out the fans on my MacBook Pro. The lowest normal speed for the fans in 2,000 rpm. They will spin up at times for no apparent reason to 5,0000 or 6,200 with nothing taxing the CPU while it's also pretty cool, usually around the high 30's or low 40's celsius.
    The other night I was converting a movie with Visual Hub, with the process taking 80% of the CPU and the temp reaching 75 c with the fans staying at 2,000 RPM until about half way through the eight minute conversion. This is a time I would have expected the fans to kick in much earlier than they did.
    I have reset the SMC previously with no effect. Coming from a Polycarbonate MacBook this machine is much nosier, but also much cooler running.
    Check out the videos I made showing iStat and Activity Monitor during these episodes. Thanks for any feedback. I'm coming to the end of my 14-day return period and wanted to verify if my MBP is operating like others.
    VIDEOS HERE.
    Thanks for any feedback.

    Thanks everyone for your comments and suggests.
    S.U. -- I ran the Apple Hardware Test when I received the computer and it found no problems.
    Travis -- Thanks for the insight to what normal range is for the MBP.
    I opened a case with Apple to get the ball rolling and get assigned a case number. The tech on the phone could not look at the videos but didn't think there was a problem from my descriptions. He did suggest I take it in for a look.
    Online I made a reservation for the Genius at the Apple Store that night. While I was waiting I was curious how other MBP's handled some serious thrashing. Since it was late and nobody was in the store, I loaded iStat Pro on three of the MBP's and opened Terminal. In two windows I ran yes > /dev/null and let them run.
    On all three machines the fan speeds never got higher than the lower 4K rpm range. They all settled in around 90C and stayed there. One MBP ran these processes for about 40 minutes and the highest fan speed I remember seeing was 35XX RPM, and again around 90C, but it would fluctuate up or down a few degrees.
    When my appointment came up I showed Rex, my Genius rep (Cleveland, Legacy Village store), what I had done on their machines just to get some perspective on how other MBP's handled both cores running more than 90%.
    My MacBook had been asleep for a few hours. When he woke it up the fans went immediately to 4200 rpm and stayed there. He hooked up a super-duper, special, double-secret HD via firewire and booted off that. The problem persisted.
    He took it in back to crack it open. He was looking for any loose connections but found none. He could not find any errors but agreed that something was amiss with my MBP.
    He was not sure if my computer, being a refurb, was different when it came to returns. We called Apple on my cell, got a rep, and he arranged for them to take back my Mac since I'm within my 14 days.
    So props to Rex for his great customer service and a happy ending.

  • My MBP temperature and fan speed

    Hi,
    My problem is that my MBP seems to be getting rather hot (the F panel at the top, and underneath in particular).
    I used to notice when I used skype video that the fans spun a little faster and it seemed to keep my MBP at reasonable temperatures. But recently its getting very hot (almost untouchable) and the fans aren't spinning faster to offput the higher temperatures.
    I installed smcFanControl2 and it showed my fans running at 1000 rpm while my CPU temperature was about 62 degrees Celsius. I've looked around the forums here and most people seem to be reporting a normal idle speed of about 2000 rpm, so thats the first thing that struck me as odd, as I'm not even using any particularly CPU intensive apps. I used Activity Monitor to check.
    I then used smcFanControl2 to up my fan speed to 4000, and it ducked underneath 50 degrees celsius, so I reduced the fan speed back to 2060 (couldn't select exactly 2000) and now its running at about 53 degrees (I'm running system profiler, console, skim, textedit, itunes, mail, and finder right now). This seems to be a much more normal temperature, and I can barely even hear the fans.
    *Now my question:*(thanks for sticking with me so far): Shouldn't my MBP automatically have upped the fan speeds to keep my CPU temperature at a reasonable 50 degrees or so? Or is the cutoff point higher and I've just never noticed before? Also, is there a program (like smcFanControl2) perhaps that I can use to set a particular temperature I want to keep my MBP at and it will automatically set the fan speed to keep it at that temp?
    NB, I recently swapped my 1 GB of Apple memory for 2 GB of Crucial memory. I'm assuming this might have bumped the temperatures up a little bit but I definitely found my MBP was warmer than usual even before the upgrade.
    Thanks for any replies!

    sternkanz,
    In general, the upper operating limit for all Macbook Pros is in the 80-90 C range. In other words, the cut-off point is higher than you think, and you just haven't noticed it. The EFI firmware and PMU is designed to managed the fans such that 80-85 C is about as hot as the CPU gets, but of course, they (the fans) ramp up a bit earlier and slightly higher temps are not just possible, but common.
    Adding the additional memory may be a contributing factor, but not by much. Certainly, having a second DIMM in place moves the heat being produced by the RAM (considerable, BTW) closer to the bottom of the Macbook Pro's case, and therefore adds to the heat you'll feel underneath. And, just having more RAM will marginally increase the amount of power your Macbook Pro uses; more power equals more heat.
    In the end, this is all normal, and I don't see that you have anything to worry about.

  • How can I control fan speeds in Win7 on a MBP-R for gaming?

    I have a MacBook Pro with Retina Display. It has had Windows 7 installed and I want to play some 3D action games. How do I stop internal parts from overheating? I intend to use a USB cooling pad but that'll do nothing if the internal fans remain at idle speed.
    The only Windows fan speed control utility I could find was the 4-year old SpeedFan which fails to detect the presence of any internal fans. I'm not impressed with the Windows community's failure to offer more and better than this tired old relic.
    So the questions remain:
    (1) Is the hardware still capable of automatically accelerating the fans as temperatures rise while gaming in Windows?
    (2) What In Windows forces the MBP-R to lock the nVidia GPU into continuous duty and ignores Intel GPU?
    (3) What control does the user have for (2)? 
    (4) How can I protect my MacBook Pro/Retina from overheating while playing PC games, apart from not playing games?

    Moved from the Creative Cloud to the Lightroom forum. They will be able to help you here.

  • What are the default fan speeds of a MBP Retina 15'?

    My settings got a little out of control, and I don't really know what the default values were, so what kind of fan speed does your MBP have in idle conditions?
    Thanks.

    2000 rpm is the base line that the fans run. They can ramp up to 6000 under a heavy load.
    smcFanControl does not let you set a minimum speed to a value below Apple's defaults.

  • Max Fan Speed on MBP

    I have checked my max fan speed for my MBP at /sys/devices/platform/applesmc.768/fan1_max and the value is set at 5700. Shouldn't the max fan rpm be around 6200? I have tried changing the file as root but I still am denied from changing it. What can I do?

  • 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.
    Release the keys.

  • Hot MBP and fan speeds - what are optimal values?

    My MBP (late 2006 17" version) seems to be running hot in the afternoons, even though I have air-conditioning on.
    I just ran Fan Control (very nice by the way!) and saw the temperature was up around 70 C and the left and right fan speeds were about 2000 rpm.
    http://www.conscius.de/~eidac/software/smcfancontrol2/index.html
    I selected the "Higher RPM" setting, which sets the minimum speeds to 4000 rpm. After changing the setting, the two fan speeds were initially showing 4525 and 4531.
    After about 10 minutes my temperature dropped to 57-59 C and the rpms for both fans went down to about 4000 rpm. And my MBP is obviously cooler to the touch. So I guess the app works.
    My questions are:
    (1) What are good, safe temperatures for the MBP?
    (2) If the temperature was so high, why wouldn't the MBP automatically increase the fan speed beyond the 2000 level automatically? Is 70 C not considered high enough to make the fan run quicker?
    (3) How fast is it safe to run the fans at? I am guessing they will die sooner if run faster?
    (4) Is making the fans run as fast as possible to first cool off the machine and then reducing the fan speed a good idea?
    (5) When it is cold, do the fans stop entirely?
    I have actually never heard my MBP fans at all. I guess they are either quiet or my room is so noisy it drowns out the fan noise.
    Thanks!
    doug

    I agree on tjk answer . To add my 2 cents:
    (2) : what is not said is that GPU shut down also the computer, but we didn't know at which temperature. It seem anyway that GPU is not designed to run at 90/100 ° C.
    at least, not the ati radeon x1600..
    Apple seem to consider that 70° is ok, but it could be also the autonomy factor which have been in mind, not the durability of your product.
    (3) the fans are brushless. so they are designed to run for very long time at high speed. But they run also with a little lubricant on they rotor axe. with time, this lubricant goes away, and the fan make noise as the axe touch more the outside. a noisy fan is coming from this.
    My Mbp was dying and becoming useless, because of fans making really big noise, and even stoping, which is synonimous of death if you don't shut up immediately the computer.
    oil on axe have cured them, for now. I can't say how long they will go, but i can play some game, or encode for 8 hours, with fans set up at 4500/5000° in smcfancontrol.
    Imo, I will try to set up fans for the macbook to not goes above 65 ° when heavily charged, and 55/57 ° when just surfing.
    So it say that I change the setting before I use some soft who need high cpu or gpu power.
    and when normal mode, safari only for instance, i have my own default setting at 2000 and my mbp is between 55 to 57°
    (my 15' mbp rev A has 1000 rpm by default, so, when doing nothing, it is at 63/65 °)
    needless to say that i didn't have any of the bugs I had since I do my manual adjust of fan's rpm. (hard reboot, glitches when playing games, computer freezing suddenly, horizontal lines while playing youtube or movies, etc..)
    (4) a better idea should be to ancipate the higher temperature, it is what i do.
    cooling fast a piece of computer is not a so good thing . as for anything (a car motor is the same..)
    so, before running a heavy game as cod4 or a crossover game, or encoding, if you start your higher rpm just before, you whole computer will not have to go up and down.
    that the same idea for letting him at 55 and not 65 . Have in mind that all composants are at the temperature, including your battery (which should be at a 30/40 ° , if we follow Apple recommendations, lol) .
    (5) no, they never stop, if they stop, your mbp burn it's intel CPU, you know.... depending on models, it is 1000, 1500 or 2000 rpm by default.
    so, a small digest of my post:
    cool down your mac, it will always be good for him .
    no need to have it at 40°, but try to have 8 to 10° less than now, in all situation.
    a fan is designed to run for a long time, not so as well as a hard disk, who can spin at 7200 or more for years, but it is designed to run for years.
    as fans are not the same on your computer than on mine, i can't give you the info, but mine have a red zone from 5000 rpm to 6000 rpm, which mean they run at their limits. it's an electrical limit, more than a rpm limit.
    A MBP cost a lot, fans don't cost much if you buy them in direct to china, or even if you bought them with apple, or if you just put some oil when they get noisy, as in your car, lol..
    if the cpu can run to 100 °, is that the case for others electronics components ?
    more than 100 peoples on that forum have a ati x1600 gpu dying..
    So my only regret is to NOT have been aware to cool better my mbp 2 years ago, because now, the damage are here, and irreversible.

  • Unusual Fan-Speed (up to 6200rpm @ 92°CPU), MBP 2011/ OSX 10.10.2

    Dear Community,
    I've got a problem with my MacBook Pro (late 2011) [2.4 Ghz/ 16GB RAM (upgraded)/ 256 GB SSD (upgraded)/ 500GB HDD (internal, upgraded (instead of DualDrive, iFixit-slot)).
    Since last week I am observing that the fan of my Macbook revs up pretty high and pretty quickly up to 92° CPU temperature @ 6200rpm of the fan according to iStats Pro. This can happen in idle as well as load of any kind. I already cleaned the fan. Never experienced it before. Pretty unusual behaviour.
    Do you have any suggestions/ guesses/ tips/ help for me? Thank you very much in advance.
    Here's a copy of an (Etre)Check that I just recently ran. Hopefully it helps:

    Thank you very much for your answer, OGELTHORPE.
    I actually did reset the SMC several times the last few days and also observed unusual behaviour by the use of the Activity Monitor – with no result.
    The CPU temperature as well as the fan speed can be at a top level without many processes at all. Happened right before I posted my question just after the last start of the system. Of course it also happens when I run a whole bunch of applications, but even in that case it differs. Sometimes it goes up, sometimes it's totally normal. That's why I called it "unusual".
    Any further ideas besides the SMC reset?

  • MacBook 5,1 Fan Noise During Normal Operation

    Recently, my MacBook 5,1 with an Intel Core 2 Duo processor and 4GB of RAM has started making loud fan noises. The fan speed is steady at around 2,000 RPM (I belive this is normal), and the CPU temperature is staying around 60 degress celcius (also normal, I believe). I have done an SMC reset, done some troubleshooting, Activity Monitor isn't showing anything abnormal, and I have not installed anything recently or been using the machine in any way I haven't in the three years I've owned it.
    Is the fan broken in some way? Is the MacBook just aging? Should I take this issue to a Genius Bar?

    A lot of people have the same problem with the iX core macs. You can try Fan Control to gain manual override of the fan speed, if it bothers you, but I have to warn you, that semiconductors should not reach a temperature higher than 85C (185F), as some semiconductors will lose their conductivity above 85C. I don't exactly know what materials are there in the iX CPUs, but just to stay safe, don't go over 85C if not necessary. Also you should know, that if a semiconductor operates on high temperatures, it can lose its conductivity sooner than it should (think 25 years instead of 28), so use carefully. You can download Fan Control form http://www.lobotomo.com/products/FanControl/

  • HT1338 MBP gets heated upto 70 celcius, but fan speed stuck at 2000rpm

    Service center person didn't found any fault.
    What to do

    In my opinion, 2000 rpm at 70ºC are normal. Moreover, I don't recommend fan speeds higher than 2000 rpm to prevent future hardware problems.
    Anyway, you can check yourself if there's a problem with the fan. To do it, run Apple Hardware Test > http://support.apple.com/kb/ht1509 To run it, connect your computer to the charger and follow the steps of the link in order to run Apple Hardware Test. Then, choose your language, tick the option to run an extended test and start the test.
    If, at the end, you see an error, copy it here. If not, your computer is working properly

  • Idle Fan speed 4400 RPM after fan replacement

    Several months ago the left side fan on my MBP died as the result of a worn bearing. The computer is covered under Apple Care so I sent it in to have the fan replaced. Ever since the fan was replaced the idle speed on both fans is in excess of 4K rpm even when the CPU shows minimal activity. SMC fan control is set to 2K rpm. iStat Nano widget displays temperature at 120 Degrees Fahrenheit and fan speed at 4500K. I took my MBP back to my local Apple authorized service center and told them what was occurring since having the fan replaced. From Hardin Apple service center in Arlington my MBP was shipped to Houston Texas where Apple Service Technicians replaced the Logic board. I have since reset the PMU by removing the battery and holding down the power button for 5 seconds. I have also run the Apple Hardware Diagnostic test using the install disc which showed no hardware malfunctions.
    With the CPU 95% idle the fans should not be running anywhere near 4K. Despite two trips to Apple Service my MPB still has a fan probably which is not only annoying because of the increased noise but it is affecting my battery life as well. If anyone has any ideas as to how to fix this problem which I have not already attempted please post them. I am hesitant to send my MBP back for more service at this time due to their failure to fix the problem the first time or check the results. They were aware of the problem when I sent it in for service and when they returned it to me the same problem persisted. This type of service does not inspire customer confidence.

    I'd be inclined to try an "archive and install" of the OS, Jason, and leave off any third party "add ons" like SMC fan control for the moment.
    Alternatively if you have an external HD then you could try installing a "clean" copy of the OS on this and using it as the boot drive, to see if this overcomes the problem
    There are OS software elements to the process of fanspeed control and if these are corrupted then the fans are likely to run at "failsafe" speed.
    Another possibility may be that a temp sensor hasn't been properly re-connected, again resulting in "failsafe" sped operation.

  • Fan Speed off the Charts

    I'm running a 15.4" 2.16 core 2 duo with 10.6.6.
    Last week my fan(s) decided to start being really loud. Right now my CPU is 92% idle and I have 1.14 gb free of my 2gb of ram (according to activity monitor), but my fans are going an average of 6000rpm (according to SMC fan control). The computer is at 43 degrees celsius.
    I have nothing set to turn up my fan speed. Any ideas?
    Thanks

    First thing is to see if a sensor has failed. Find your original system disk/s and use the one that is marked as bearing Apple Hardware Test. Instructions are here:
    http://support.apple.com/kb/HT1509
    Note that the fans will run high (6000 rpm max) while running AHT. That's normal. I set my MBP up on little spacers to allow air underneath during the test.
    Most people don't have the translator for any error codes that might appear, but if you post the errors here, some may look familiar enough that one of us can take an educated guess. Errors with "SNS" embedded in the code are generally sensor codes.
    There are several things you can do to investigate heat/fan issues:
    1) See if any background processes are eating up CPU cycles. Quit all running user applications so the computer is at normal idle. Find Activity Monitor and launch it. IMPORTANT: change the "Show" pulldown at the top of the AM window from its default of "My Processes" to "All Processes." Some of the real culprits may not show if AM only checks user processes. There is a column for "%CPU." Click that column header to sort by CPU usage.
    If any process is using more than about 25 percent of the CPU cycles while the computer is idling, post the names of the processes and we can see if they can be eliminated.
    2) Make certain your physical arrangement of the computer and your usage patterns are not contributing to overheating. Apple recommends against using the MBP on your lap or any surface that contacts the case bottom. The case bottom is part of the heat dissipation system and needs air. If you need to use the computer in your lap, make a simple lap board from scrap plywood. The height of the rubber feet is usually enough to let the air move but, if you are playing graphics-intensive games, you may want to insert some 1/2-inch (13mm) spacers, or get a powered chill pad to help move heat away.
    The main exhaust vent is under the display hinge on the back panel of the case. It must not be obstructed.
    Here is an Apple article on temps but it does not list critical temps for any model:
    http://support.apple.com/kb/HT1778
    For the silver-key MBPs, the safety shutdown to prevent heat damage is aout 100C/212F. Your 43C is well within the normal range and should no be making the fans go all out unless SMC Fan Control is set to do so.
