    My MBP 13" early 2011's fans were screaming at me so loud just a few minutes ago. All i had open was firefox and itunes. I shut it down and it is quiet now but a bit louder than usual. It's in it's usual place and it didn't make this much noise before. Any ideas? thanks

    I'm a huge fan of these things, but I wouldn't call myself crazy...

    One of those apps was causing your cores to work (causing heat) for whatever reason. It's impossible to say anything more specific from just your OP.

    I had the same problem when I had either FFx or Chrome open. I think it had to do with Adobe flash, or possibly some bad extension I downloaded.

    I solved the problem by uninstalling both Chrome and Firefox, and the files in the Library files. I forget the precise location, but I am sure a Google search can help you there.

    Just uninstalling the app will not help as the bad stuff was in those files.

    Now my fan isn't running all the time on high when browsing normally.

    Check the activity monitor to see which app is causing the load.

    my fans go crazy often since updating to lion. ugh.
    but everything is working well, living with it (for now).

    at least they serve a purpose (which, i believe, is to make as much noise as possible...)

    iStat Pro will give you accurate readings of your fans and temps, among other things.

    Unless there is a rare defect in your Mac, your temps are well within the normal operating range, considering the workload you're putting on it. Websites with Flash content, games and other multimedia apps will put higher demand on the CPU/GPU, generating more heat. This is normal. If you're constantly putting high demands on your system, such as gaming or other multimedia tasks, expect temps to rise and fans to spin up accordingly. It's just your Mac doing its job to maintain temps within the normal range.

    Your fans are always on when your Mac is on, spinning at a minimum of 2000 rpm (for MBPs) or 1800 rpm (for MBAs, MBs and minis). They will spin faster as needed to keep temps at a safe level. If they're spinning up without increased heat, try resetting the SMC. PRAM/NVRAM has nothing to do with these issues, so resetting it will not help. Also, make sure you don't block the vents, which are located at the rear, near the hinge.

    Learn about the fans in your Mac
    Apple Portables: Operating temperature

    Launch Activity Monitor and change "My Processes" at the top to "All Processes". Then look to see what apps may be placing high demands on your CPU/GPU.

    Thanks for the help man. I was watching a video on facebook so that could be the problem. I just thought it was weird because all I was doing was watching a video and the fans were just going wild. They were quieter when I was editing w/ Final Cut Pro. :/
