    Hey all,

    Just bought the 2799$ rmbp with 2.7/512/16. Today, Ive noticed something weird...when I copy many gigs from a usb3 drive, the fan goes crazy. This doesnt happen on either my old 2012 15" rmbp or 2012 13" rmbp.

    Is this normal? Ive reset PRAM, restore ML, etc. No change.

    Not happy with that.

    My rMBPs fans go crazy when running the eMail app on background.

    Ive never even heard the fans while running OSX on my 2012 rMBP. The only time I hear them is when gaming in Windows.

    Yes! I picked up a 2.7, 16gig today and it was going full pelt just sitting on my desk not being used. This replaced a MBA so I'm used to the fans kicking in but even the air never went off like this does.

    I need to run all my warrantied Apple gear back to the store and demand new ones it seems. The idea that the fans come on when it is worked is totally unacceptable. What were they thinking?

    New replacement does it too. Makes it seem inferrior to the 13 rmbp it sits next to. Has to be a firmware issue but man this CPU gets hot. The 2.3 only ever got to 95 but the 2.7 gets gets to 106

    Did you tried SMC reset?

    When you copy several thousand of files,
    MBP does the indexing (you could check it in Spotlight)
    Indexing is CPU-intensive, and, as result, fans run high.
    This could be observed on any MBP.

    I think you might start enjoying your rMBP instead of worrying about some degrees above on the CPU, if your rMBP get damaged from the heat Apple will replace it. The faster the CPU the hotter it gets.

    You are missing the point the cpu will be at idle and the fan will kick to max not doing anything but transferring 1 20gb file from a usb 3 drive.

    ----------

    While I agree it's only copying one file once it goes over 4gb transfered

    Maybe the SSD gets hot when copying files and the fans go off to cool it down. The fans not only refreshes the CPU but all the components and circuitry inside, all of them can become hot.

    Maybe but again not happening on other rmbp not a big deal it'll just go back

    I have the same 2013 rMBP setup, as soon as I get home I'll do the same test and see if mine has the same behavior, I'll let you know whatever happens.

    I just received my 15" rMBP yesterday (2012 model) and its doing the same thing under pretty minor load. Typically when downloading or moving a lot of data.

    I'm thinking this might be related to the EFI 1.0 update which has known CPU/GPU throttling issues with ML. It would make sense that if ML is too aggressively downthrottling due to temperatures that it would also aggressively throttle up the fans.

    Not sure if there's a fix other than waiting for a OSX or EFI update. I'm sure all new rMBP are shipping with EFI 1.0. Mines not even 2013 and it did.

    I have two (15 and 13) rmbp and neither does it. Strange.

    my fans come on randomly all the time. activity monitor shows no load on the cpu when it happens.


    this happend on two 15R i have owned. one a 2012 and the current is a 2013


    edit- didnt pay attention to the 2012 thought it was normal guess it not.

    Must be something weird going on with your rMBP. I've transferred over 4TB of data from USB 3.0/Thunderbolt without any fan noise. I was streaming HD on YouTube while transferring too. =/ Exchange it!

    Ok, I just copied 6.2 Gb of music from a USB drive to my rMBP, took about 4 mins and the fans never went off on mine.

    Are you running Activity Monitor during the transfer and looking for high CPU usage by the Spotlight processes, mds and mdworker? Have you tried installing a program like "Hardware Monitor" which allows you to see all the internal temperatures, as well as fan speeds? It would seem really strange if the fans are running fast while the temperature of the key components (CPU, GPU, SSD?) are well below their max.

    Yep. Istat reports idle temps in the low 40s and all components seem cool. No CPU load in activity monitor and CPU is generally at <4% load.

    Spotlight is not indexing either.
