I did as described in the first parts of this thread.
Downloaded the latest from osx86.net, so not the 582 version.
I use DSDT editor, not the DSDT SE app, as I can't seem to get that one to compile without giving me some weird issue, even on an unmodified DSDT.
So when I found the DSDT editor app, I could apply the first piece of code that BigDonky posted. This worked in the sense that after I changed the 'monitor' part in one of the kexts, and installed the KEXTs via KextUtility.app, I could read the fan rpm in HW monitor.app.
So far so good.
I think that there is an issue though with the next part of the post that changed the DSDT.
I replaced what was there with what BigDonkey posted but booting with that gives me weird results.
First of all my wifi disappeared and some other box with which I could switch off some other device(s) came into view... huh? Also the battery status went to 'battery' rather than showing the power source to be the power adaptor... che?
And the fan was still the same anyway.
I have a bog standard 4530s with i3-2330, 4GB, no ATI, bios F0A, ... here is my DSDT which I used by booting with DSDT=/Extra/DSDTnewfan.aml (let that be a tip for many who try this and want to fallback to working version by doing nothing but a reboot!!!)
The DSDT editor compiled it fine, and produced an AML file which I saved, attached here.
Funky...
I really like to get rid of some fan noise pls. Yelp!
==> New status <==
I don't know why as I did this several times, but I said 'one more time'... and so I rebooted (cold) with the option (in my case DSDT=/Extra/DSDTnewfan.aml ) and voila!!!
It works now... a bit higher temp but I can live with it, and a much much lower noise level as the fan speed dropped 500 rpms or so.
So I attach a pic of it, running, I also seem to have a CPU heatsink temp now in HW monitor... kewl!
Only other plan of attach I would have had to do this is somehow lower the CPU voltage, as it seems that the CPUs actually can take that quite well and still operate. (Less Volts = Less heat... so less temp, and we could then maybe drop below 30 together with (for me taking the whole thing apart and) changing the heat sink silicone and putting Arctic Silver 5 on it...
The other method would be patching the BIOS but... yeah, never mind.
So fine... seems this works now!!! Fantastic so far. Big thanks to all involved! Looking forward for BK to put it in the installer (bet that is a bit of work
)
