    hello

    sometimes, when surfing the web, fans are suddenly spinning faster for 30, 40 or 60 seconds without any particular reason on my 15" rMBP

    i don't think the pages contain any flash or html5 videos


    have you ever encountered this situation ?

    is this normal ?

    yup, I have a new 2012 rMBP 15" and occasionally it goes nuts on the fan for a minute or so too. Generally when I'm downloading from the net at full whack.

    haven't had it do it otherwise, even when encoding with handbrake - which taxes it nicely.

    anyone else had this?

    (got mine early Jan 2013)

    yes, just got mine also this week (15" i7 2.6 Ghz 16 Gb of ram)

    working on photoshop by opening 50 RAW pictures (50 Mb each), no problem, 0 fan noise at all


    surfing randomly the web with chrome sometimes drives the fan nuts :confused: :confused: :confused:

    Seems like I've heard things lately of Chrome having memory issues -- might drive up your fan as well.

    And Safari has memory leaks, too.

    I just use Firefox :)

    I have a normal MBP (15"; 2012 model) and have never had problems with Firefox since I've had it. I've never seen it eat up more memory than a reasonable, adequate amount per various situation(s).

    I have gfxCardStatus installed, and do notice that when on certain webpages, my graphics card will change from integrated to discrete (and visa-versa), but that's because the page I'm viewing has Flash and/or HTML5.

    Normal web browsing fan speed: around 2000rpm.
    Normal web browsing temperature: around 45 Celsius.

    well it's not relevant to compare normal MBP and rMBP simply because fans are not the same, rMBP is built differently as it is much slimmer...

    my fans spin when the machine is under big load, sometimes the loads make no sense (something in the OS, fx i had a proplem with social media and notification centre)
    but general usage it stays quit.
    have smcfancontrol i use once in a while to get the fans to spin a little more just to hold it cold when watching HD movies

    smcfancontrol seems useless, like it cannot force the fans to remain quiet

    It's not "useless". It's used to make the fans go higher when you know your computer is going to heat up. That way, you can keep it cooler.

    Chances are, if you "forced" the fans to remain quiet, you could very well overheat your system.

    I have had my 15" retina on 10.8.2 since aug 2011 and use safari exclusively, I have changed 3 things and works like a charm, disable java(not java script) in preferences, changed save history for 2 weeks, and installed click to flash extension. Reasoning java - security(only some specific sites use java anyway), the save history is where the "memory leak" is if you leave this at the default year or what ever it is safari will grow to gbs in size in the ram changing this to 2 weeks never reaches 1 gb. The click to flash saves battery and converts flash to html5 if possible, and if you want to use flash on that site just click it.

    Point of all this is that my fan dose not become "noticeable" in normal usage, even when using Matlab or circuit analysis does the fan change from normal 2000rpm and 2200rpm. Only when playing games, and when using multi monitors with video editing does it start to become noticeable.

    If you have used as monitor programs or fans reading/control apps try uninstalling them and do the SMC & PRAM resets as the fan control could have been altered.

    That's my experience, take it or leave it.

    I'm getting this purely doing app updates from itunes and nothing else running

    definitely related to using wifi for me

    as advised by some people, reset of SMC and PRAM didn't fix anything

    someone told me about a clean install of mountain lion


    how a clean install vs factory install would fix things ?

    thanks

    This isn't normal, I never experienced that (sept 12 rmbp with webkit).

    What browser are you using and on which website does it occur? Can you reproduce it?

    I guess it won't help you, but i'll share my experience anyhow.

    I found out that whenever i was using Bittorrent, the fans would almost always spin at 5000+ rpm. Ever since i use µTorrent i haven't heard the fans spin up.

    i now use safari instead of chrome

    and utorrent instead of transmission

    but still it happens and i can't reproduce it, it happens randomly

    which makes me really upset

    i also just did a clean install today, but still random fan madness


    i have asked an apple store to order a replacement panel for my light leak
    i'll take this occasion to ask about the crazy fan too
