    You didn't run heavy tasks like gaming or video editing, 4k video watching, 3D/sound rendering for a week or so? Fans are running only on lowest speeds for a while?

    My advice: Let the fans run on maximum speed for a minute or so at least once a week. It will blow through all the nearby hardware components and some dust and other small particles will leave your device. Do the "rush through task" immediately after you hoovered your room and cleaned your desk for being sure that you don't push even more dust into the device. Seriously you can take it into your (dry and clean, tiled) bathroom because it's always the room with less dust. No smoking during the task.

    To accomplish this you don't need to open your device but download and install the free tool SmcFanControl (donationware, needs 10.5 or newer; source code @ github.com) and max out the settings for both fans. (Tested on rMBP. Read the FAQ. I am not the dev—just passing the info.)

    The setting "max" is not provided by default so you have to add and save it manually as shown in the screenshots.

    Edit: Okay nothing is as completely and thoroughly and efficiently than taking the device apart (you'll need some special tools—for the rMBP—and skills and take care of the warranty) but the "software solution" is clearly "better than nothing" and the life span of the device will be extended. :cool:

    It takes me less than 10 minutes to unscrew, remove, and clean the fans on my late 2008 mbp :). I am saving on my electricity bill... ;)

    Fact is, there's only one way to properly & completely clean out your computer. Plan to spend some time, so you're not rushed & take it apart.

    Nothing beats taking your time to clean it, inspect it, and make that a semi annual routine. You'll be glad you did.

    Or you can take the back plate off, clean it with dust off and know for a fact your actually getting rid of the dust.

    So it is okay to blow air into the fans? I've heard differing opinions on this, some people say it will push dust into the bearings. My MBP is only about a month old so I won't even try this for probably another six months or so. Maybe only once a year.

    Good idea! Do the "rush through task" immediately after you hoovered your room and cleaned your desk. Seriously you can even go into your bathroom because it's always the room with less dust.

    My rMBP is two months and I did it. It won't hurt.

    For people saying to unscrew the laptop, it has screws you cannot find in a regular store. Apple ment for you to not open it.

    Only on the Retina model, my 2012 15" MBP has regular (though very small) philips-head screws.

    Ya on the retinas. Obviously your not going to be tinkering around in there like you would with the cMBP which has little philips screws. You
    Can buy a pentelobe screw driver on ebay.

    Seems as advisable as the clean cycle on my oven.
