    I have huge problems with the fans of my Macbook Pro 15" Early 2013 is running all the time.

    I understand it needs heating, but having the computer on my wooden desk and hearing it running all the time really is very irritating.

    Sometimes also the kernel_task process suddenly takes up all the resources of the computer.

    I wouldn´t suspect this from a powerful Mac like this one:

    MacBook Pro (Retina, 15-inch, Early 2013)
    CPU: 2,7 GHz Intel Core i7
    RAM: 16 GB 1600 MHz DDR3
    GPU: NVIDIA GeForce GT 650M 1024 MB
    Serial: C02KH3KXFFT1

    Any advices on how to get the fans and system running normally again ??

    Any help will be HIGLY appreciated.

    Here´s a normal OSX-rapport on it: Pro.spx?dl=0

    Here´s also an EtreCheck-rapport on it:

    EtreCheck version: 2.4.2 (142)

    As an initial test, try rebooting and hold the shift key when booting. That will do a safe mode boot that stops all startup and login items from launching. Use the computer like that for a bit and see if the problem goes away. If that fix it, then you know it is one or more of the startup or launch items in the Etrecheck report causing the problem and you need to start removing them to figure it out.

    Right off the bat, I would remove CleanMyMac. That app is a mess and causes users a lot of problems.

    Sadly my internal monitor is destroyed at the moment. I am just using my Mac with two external monitors right now. I am sure Safe Mode will not function with these external monitors ?

    Update: I tested to disable all the startup apps now except Dropbox and Spectacle, and the fan problems STILL persists. It runs like the wind!

    Also I noticed the fans running BEFORE I even had logged in, so I don´t know what to do with this computer...

    (Btw: I also had similiar heating problems and fan problems with my old Macbook Pro 13", also from the same year - 2013.)

    Safe mode will work with an external monitor. Give it a try.

    You can't stop things like that CMM just by removing the startup items. You need to go to /Library/LaunchDaemons and remove those plist files.

    Hehe CleanMyMac has been removed.

    I did discovered that this was cause by though: The two external monitors. Almost instantly when I plug these DVI-monitors out their Thunderbolt-ports, the fans starts slowing down.

    I´ve read something about that this might be the reason, and that newer monitors will probably work better regarding to this.

    my 2010 17inch mbp was annoying me with fans getting loud for even running a video or flash - just to let you know using the 13 inch 2015 retina macbook pro it is totally silent operation most of the time - you can watch full HD and run 4K on external 4K display and the laptop is totally silent, though I am reading that this is not the case with the 15 inch, probably because it has more intensive processors and graphics card - so if you want rid of the fan noise problem I recommend the new 13 inch, apple have really improved things in terms of fan noise with it

    Am I the only person on this board that isn't obsessed by fan noise? I prefer hearing them and knowing they're doing their job rather than a silent computer.
