Acer MXM BIOS Mods and discussion (was: x920G vs. 9600M GT)

Are you sure you did a good job on putting thermal paste on the GPU?

I think I have some news guys!
I have removed the 9500M GS from the bios modded 9920g and I have installed it again in the laptop with the original bios.
I've checked the temperature and I can confirm that in the non modded bios laptop the gpu very rarely goes above 60 degrees Celsius and this happens only when I push it.
So I definitely think there is a big problem with the modded bios in terms of temperature management or something like that.
Also in the non modded 9920g with the original bios the fan stays almost all the time on high.
In the bios modded 9920g it never runs on high and it stops from time to time.
So I have no clue what is going on but I really do not understand why the temperatures are so different from one laptop to another using the same 9500M GS and the same cooling system.
Any ideas guys?
Thank you!

Well, I recompiled the ACPI DSDT in the modded BIOS with a compiler newer than the one used in the stock BIOS,that could somehow be the cause.

Can you test if the fan spins up in response to heavy CPU load, but no GPU?

@.NetRolller 3D
Fujitsu-Siemens Amilo A1667g and A3667g are working with nVidia 9600m GT after flashing your BIOS, though I do get some screen flickering probably cause of PowerPlay(or whatever it is called in nVidia).

Thanks!
