MacBook Pro - Fans spin up on power on

Hi,
I got my MBP back the night before last night, it was in for a major repair in which they replaced the Main-board (includes new SDD, RAM, Fans, I/O board, I/O Flex cable as well as the Clamshell Retina display (Complete))
The issue I was having before, after my MBP "burn-out" something inside, which caused them to replace everything, still seams to be happening.
My fans spin-up as soon as you turn the power on.
They also stay on the whole day (and never go off).
I know this is not the standard case with the MBP - as I have confirmed this with the genius at the apple store when I took it in last night - and he told me that it was "not doing it any more" ... and I got home, turned it on... and it was doing it still .... what a waste of a trip to the Apple Store on that one
I wanted to know if other had this issue, and if its perhaps an installed app. I have the widget iStats (which is loaded on the widget screen all the time) ... To check things, and after googling things, I installed smcFan control... in which I am NOT able to tell it "not" to spin the fans, there is no option in the APP that has a minimum speed of 0 (zero) I also installed the "Macs Fan Control.app" - which also does not have the option to make a zero minimum spin speed.
Because the MBP's fans come on immediately when I turn the power ON... and stay on through log-in, and boot up... and the whole day... I struggle to see it as a software issue - unless one app along the way set something in the machine config that tells it to always be on...
During use of the MBP, and when it does get "hot" ... the fans also do not seam to spin up faster to cool it down, knowing that this algorithm may think its not necesary to cool it down when the GPU Diode is cooking at 155 degrees F - the SSD is running over 115 degrees F - the CPU Heatsink is at 126 degrees... and so on... I in this case used smcFan to cool it down by manually increasing the fan-speed (I otherwise do not have either of the fan-speed apps running automatically on boot, the only one is the iStat widget, which as far as I see does not "control" it only "reads" the values)
Is there anything I can check for this.... I really don't want to waste my time again going to the Apple Store to have a genius tell me they are not on, to get back home again to see that they are still on :S
Thanks!
Brad

EDIT: I notice that when using smcFanControl, you can set the "Default" for the fan speed... In this app you can not select a minimum speed of less than 2100 left, and 2000 right... Going into the other app, Macs Fan Control (MFC) it tells you the minimum speed that "can" be used is the same as what I make the minimum with the smcFan app... i.e... If I make the minimum for both fans 4000 in smc, then close it... and open MFC... then MFC tells me that the minimum fan speed is 4000.... This makes me think that smcFanControl is updating a system setting to tell is what the minimum fan speed is... which would make sense that when booting from power off, the fan speed is already set to the minimum. ( I will confirm this by setting it HIGH, and powering off, then powering off again - and will update this thread ONLY if I am wrong in the understanding that on powering ON again, that my fan speed will come on as I power on at the HIGH speed that I set it in smcFanControl!!! Only if I am wrong) ... which would lead me to the question to the Apple geniuses, of "How do I then set my "default" minimum fan-speed back to zero?? ( and I can then un-install the fan-applications, as I only installed them to see if I could control the fan speed to make it zero, which I can't)
I have only a few apps open right now while I type this, and checking activity log, FireFox which seams to be using a LOT of cpu power for me to type into this box (I must be typing blazing fast - not ) ... which makes my GPU Diode to go over 155 degrees F :S)

  • Macbook Pro Fans Just Went Spinning Nuts

    Hi.
    So I'm surfing the web (using firefox) have 2 tabs open and suddenly the fans on my macbook pro start to spin faster. Then they spin faster gain finally maxing out at 5360 rpm. The temperature all the time was never above 55 degress C. They spun at 5360 rpm for about 10 minutes and then spun down to a normal level of 3154 rpm.
    I checked the processes and some kernal task is up at the top using 1.84 GB of virtual memory. No other programs running but plenty of other tasks listed as sleeping.
    First question ... what is the max rpm that the fans should safely spin at?
    Second question ... why would it suddenly take off like that spinning fans when there's only one program running?
    I had an alienware before and it started running its fans like that after a few months ownership ... a few months later it chew the hard disk and lost a lot of data on me.

    The maximum RPM for the MacBook Pro fans is 6000rpm.
    I have no idea why the fans would suddenly "take off" like that but try running the Apple Hardware test. You can do this by inserting your original install disk 1, restart the computer with the D key held down until the hardware test starts loading. Once the test has loaded select the option to perform extended testing and then start the test. Note down any error codes and post them here.
    Note that when you load the hardware test up the mouse will be very jittery and the computer will appear to freeze during the test, I have encountered this on all the tests I have run and consider it normal behaviour.
    Hope this helps

  • What is causing my Macbook Pro fan to run constantly?

    Hello. Recently my Macbook Pro fan has begun to run constantly at high power. I've checked the activity monitor and even when there is little RAM or CPU this occurs. I am wondering if the issue is the hard drive because the I am seeing spikes in disk activity at random times even when I am not using the hard drive. The computer is actually heating up when the fans are on at full power, so this also leads me to believe it could be the hard drive. I have already tried resetting the system management controller. Any other ideas? What should I do about this?
    Thanks a lot.

    Try raising the the the machine with wood, or , plastic botttle caps t get it up an inch or so, that way there is more air flow under the MBP to help with the air flow to help keep the cooling more een.  Hope this helps.

  • Macbook Pro Fan Speed

    Hi. I was having some trouble with my temperature of my MBP, but I somewhat solved it using Temperature Monitor and smcFanControl. I turned the fanspeed to Higher RPM in the smcfancontrol menu, and my temperatures are down from ~95 celcius to ~65 celcius (when playing Minecraft / other extensive tasks.)
    Now, I would like to bring them down more (should I?) because I feel 65 c - 70 c is still really high...
    So, my only question is: In smcFanControl, the Higher RPM setting is 4000 RPM, should I change that to 5000 RPM? I know it would help, but, can the fans handle that?
    Thanks in advance
    Could 70c (max) shorten it's lifespan?
    (sorry I just am extremely extremely paranoid)

    I am seeing a lot of negative talk about third-party software to control fans:
    Istat menu 5 is good.
    It conforms to apple's SMC; this means that it will never allow the fans to go slower than what SMC is asking, thus your computer will be safe using this software.
    In contrast I have a Macbook Pro fan controller for bootcamping Windows 7 called MacFanx64.exe (64 bit) that requires you to understand command prompt.
    It's nothing difficult, you just need to make sure that you enter parameters properly.
    The only way I see one of these damaging any hardware components would be if you accidently told the fan to spin faster than the max speed.
    I would agree that for OS X you aren't going to really need this because the engineering on the SMC isn't terrible, but if you happen to have SMC screw up like it sounds like you had, there's no way to know it unless you feel it getting really hot like that which I'm sure isn't great for your MBP.
    Therefore having a monitor system is helpful because you can see the temperatures constantly.
    Now for Windows 7 bootcamp it's a whole different story.
    There is something wrong with the drivers that control SMC for bootcamp because the computer will get hot fast even in idle.
    I was marking temperatures around 60-70 C just in idle - the fans still stay at 2000 rpm.
    If someone finds something better than MacFan for Windows 7 bootcamp let me know.
    Moral of the story, if you pick a good third-party application you're not going to harm your computer.
    Think of it like a second line of defense.
    Last but not least, if you're still having this problem do an SMC reset.
    Apple has instructions on how to do it, just note that you need to pay attention to whether your MBP has a removable battery or not when doing SMC reset.
    Cheers

  • Macbook pro fan running slow

    macbook pro fan is running slow and hot.  it fluctuates between 212 and 375 rpms.  heat rises up to 104c.  do i need to replace the fan?

    Before I suggest advice, I urge you to keep your machine under 160F at all times. I don't want to sound like an alarmist, but you can seriously damage your machine with that kind of use. Some solders melt at 225F, weaken at 190F.
    You may have to replace the fan - or you may need to clean the inside of your machine and fan. It's hard to tell without inspecting your machine.
    Or you may find that you need to get a different browser, and become more aware of temperature; laptop machines are much more sensitive to termperature issues than desktop Macs. Some day, you'll thank me for that advice.

  • Mainstage 2.1 makes my Macbook Pro fans run full bore.

    Upgraded to V. 2.1 and Snow Leopard. Now my Macbook Pro fan kicks in at full blast whenever I play any patches or run backing tracks. Cpu hit looks low and memory usage is average. This never happened before. Any ideas as to what's happening?

    My MBP fans have always run at full capacity when using MS 1, 2 or 2.1. They start out running normally but then start to rev up after a couple of minutes. You could try running some fan control software to manually adjust your fan thresholds but ultimately, does it really matter if the fans are running hard? Seems to me that they're running hard because they need to....MS is still very hard on system resources even if the meters say otherwise. It's the only app I run that causes the fans to run flat-out.

  • Can you macbook pro with a 220 volt power adapter

    Can you macbook pro with a 220 volt power adapter

    The power supply for the MBP will run with any voltage between 110 and 240 so there is no need for a voltage power adapter.

  • My MacBook Pro fan runs while sleeping

    My MacBook Pro fan runs constantly, even while sleeping.
    The problem started about 2-3 months ago, but was pretty rare. When I noticed the problem, I would restart the computer and it would stop for 1-2 weeks. More recently it has become more constant, and now it always has the fan running when it's sleeping.
    Any ideas on what I should do? Thanks!

    Mine too. If you're worried you might like to try a laptop cooler like one of these:

    Not sure how well they'd work on a Macbook as there aren't any vents on the underside but it couldn't hurt and they're quite cheep.

    Hey Unknownflavour,
    There an be a few different reasons why your fans are running. I'd read up on the function of your MacBook Pro's fans in the following document:

  • Using my macbook pro whole day with the power adapter , will it affect my battery? Please help

    Using my macbook pro whole day with the power adapter , will it affect my battery? Please help

    It doesn't affect the battery. You can use your MacBook Pro plugged in all the time without damaging the battery. You only have to be sure that you unplug it and run a battery cycle (drain the battery without letting the Mac turn off and charge it fully) at least once a month to keep the battery life.

    If a SMC reset does not bring life to your MBP, make an appointment at an Apple store genus bar for a free diagnosis.

  • New Macbook Pro FileVault Encrpytion Paused "Connect power adapter to resume encryption"

    Does anyone have information on what is causing the FileVault encryption error with OS X Yosemitie? I just purchased a new 15 inch 2.5 GHz (mid-2014) MacBook Pro and during the initial installation / setup I elected to use FileVault to encrypt my 250GB SSD. As the encryption process was completing, it gave me an error stating the encryption was paused and "Connect power adapter to resume encryption."
    The MacBook Pro is connected to its power supply. I should note this is my second MBP, I had this same issue with the 1st MBP, which was returned to Apple and replaced with another new MBP. I just don't understand how Apple can release an OS with an option to encrypt the drive if it doesn't work.

    So, after 30 minutes with a support person on chat I asked to be escalated. During the time I waited for the sr. tech to come online I decided the best course of action was to erase the disk and re-install Yosemite. The sr. tech came on and said they are very much aware of this issue and the solution is to erase the disk and re-install Yosemite. This was quite easy.
    I followed these instructions which matched what the sr. tech provided: OS X Yosemite: Erase and reinstall OS X
    Just be sure to erase the correct disk. For me it was the 2nd Macintosh HD in the list.
    Also be sure to choose Mac OS Extended (Journaled) as the format, not Mac OS Extended (Journaled, Encrypted).
    You'll need to re-install the included apps (Pages, Garage Band, etc.) by going to the App Store and choosing Purchased.
    Hope this helps!

  • Do you think my macbook pro fan could be broken?

    Earlier today when I opened my laptop the screen was black and it appeared to be shut down. I hit the restart button and when the screen came up it said that I had "shut off my laptop due to a problem", though I did not manually shut it down. It was working 100% fine yesterday, so I'm not sure what could have happened to it. I know it wasn't my battery, because I had a full charge prior to shutting it and upon restart I still had a reasonable charge. I was more or less ignoring my laptop's unusual pop-up until I noticed that my computer was feeling much hotter than normal, so I checked iStat pro to look at temperatures. The CPU temp was around 82 degrees or so when I checked, while I was playing a videogame, which doesn't seem too high but the area around my keyboard felt much hotter to the touch than normal. What is really concerning me is that iStat says my fan is running at 0 rpm, even while I was playing a graphic-intensive game. The CPU is down to 65 degrees since I have stopped playing the game, however I have heard that your laptop will shut itself off to prevent overheating, and I'm wondering if this is what happened to my laptop sometime between yesterday and today. Does it sound like my fan could be broken? There isn't an apple store very close to me and my warranty just ended so I'd rather work it out myself if possible. I don't believe it is a faulty sensor either as iStat gave me temperature readings for everything. If you think my fan is broken, do you have any advice or know how much it would cost to fix/replace?

    Good detective work.
    I don't believe that 80ºC is extreme for occasional use, but over extended periods of time, this can stress your machine. I beleve you should visit your local Apple Store. They can determine if the fan is broken.
    In the meantime, I could avoid:
    - CPU-intensive activities like 3D gaming for extended periods of time.
    - Using your notebook on your lap. That can raise its temperature thirty or more degrees.
    - Dust or dirt can choke the fans, increasing temperatures and even the risk of fire.
    Replacement of a fan is not very expensive, if it comes to that. You can also do it yourself:
