    Can it be done, or can it be replaced with the old firmware updates?

    EFI and SMC updates that have made my MBP far noisier than it was before the updates, at least I think it's them. Don't think any of the other updates would have interfered with it that much?

    from here


    I guess you haven't monitored the temps and CPU usage and fan speed at several times to exclude the possibility, that it is not the firmware?

    I have done all, honest.... but there's no way a MBP that's been working perfectly for nearly a year, only does this a minute after the updates are applied?

    I still don't know which Mac this is.

    I think it all depends on how Apple delivers the updates. If they are delta updates, reversing them will be very difficult.

    That's why knowing which hardware revision this is would be very helpful.

    Sorry yes, they are SMC firmware 1.5, MBP EFI firmware 2,7, perhaps Thunderbolt software update, but doubtful, and I'm guessing security update 2012-001 1.1 wouldn't interfere, nor 10.6.8 v 1.1? Early 2011 MBP running i5 SL

    Is this me?

    This CD cannot be used to return an Intel-based Macintosh computer's firmware to a previous version if a successful update has already been performed.

    Maybe so. :(

    I do know there is a hack to get the 2007 firmware on 2006 models so that they gain support for other CPUs and more RAM.

    I can't find it now though.

    So not fair.. Was really happy with this, and now I don't even want to use it anymore. It's just so distracting to work on. Why do Apple care if we revert back to a time we were 'happy' with it. The date is March 2011 stamped on the box, so I don't want to go back any further than that. Not too much to ask?!

    Are you near an Apple Store? The geniuses might have tools we don't have.

    Well I thought they may be an option, but Apple won't allow it, so.... it's a no go unfortunately. Spoke to them this morning. Most unhelpful and warning of consequences etc., but I kind of expected that to be honest. They don't like reverting back to older firmware, '3rd party' as he put it, and you kind of have to live with their 'improvements'. A quick scan of the web says the EFI 2.7 is only meant for Lion as well, not SL.

    Then maybe you can monitor the temps, fan speed and CPU usage and find some correlation and then ask Apple to fix it, if it is tied to the newer firmware?

    Only option now probably?
    All the normal and usual things I've done on this for 10 months that have been pretty silent operations are now noisy and just an annoyance. I'm falling heavily out of love with my Mac

    Okay, this is taking far too long now.

    Tell us your reported temperatures of all the temps iStat Pro lists, then tell us the actual fan speed and then go to Activity Monitor and report back:
    Open Activity Monitor and select All Processes and then sort by CPU to show you the process(es) slowing down your Mac.

    You cal also make screenshots and attach them to your next post?

    And if it's not Fans, will it tell us what it is, Would a noisy HD show up on there?

    No. But you could take your ear and listen to where the sound is coming from.
    Here is a teardown of the 13" MBP (2009 and 2011 MBP models are alike), thus you know what is where: MacBook Pro 13" Unibody Mid 2009 Teardown

    Damn, that makes me want to pull it apart... what's on the right hand side below keys? Think it's that region

    Directly below the keys is the ODD (look for the slot).

    In line with the trackpad is the HDD.

    Could something be rattling in your ODD?

    I wasn't sure what that was showing as it was upside down, but the part under the keys, right of track pad, seems to be worst offender since update

    That would be your HDD.

    EDIT: Cheap and easy to replace.

    Is your HDD almost full? Are you running out of physical RAM and swapping out to disk?

    Says 238 available on a 320, so not really?

    Why would the updates have interfered with it

    ----------

    a hand over the right hand side dampens the sound yes??

    By over you mean? Palmrest? Covering the ODD slot?

    If the slot I'd say blow out your ODD (gently) with compressed air.
    If palmrest, I'd still suspect the HDD.

    The fan is in the center of the back and is most audible at the hinge.
