from hereSMC Firmware update 1.5 Snow Leopard, it appeared after 10.6.8 was updated.
It's a bit over 2000 on idle, but it's a hell of a lot louder than it was before the updates, as well as going a lot higher after a few short minutes of doing very little, whereby before it never came on or was heard rarely. Now it goes manic after a few short periods. If it is that firmware update now causing these problems, please can you tell me how to get rid of it?
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?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?
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.

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
And if it's not Fans, will it tell us what it is, Would a noisy HD show up on there?
damn, that makes me want to pull it apart... What's on the right hand side below keys? Think it's that region

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
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?

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