Fans and I2C touchpad fully works in Ubuntu.
This is video demonstrate it http://www.youtube.com/watch?v=AyAuliW4oJw

Ubuntu probably has support for ACPI-based fan control. Not so much OS X...
You need to find a way to make the EC control the fans without OS support.

So... help me please

Click to expand...

Check BIOS settings for fan control... Examine DSDT for clues to how fan might be controlled. Test theory with RW-Everything in Windows.
 
In bios settings I only can set temperature for passive cooling and temperature for enable active cooling.
In DSDT I found section with fans.

Can you tell me is it possible to detect my fas in OSX to control them in HWMonitor app, for example?

Can you tell me is it possible to detect my fas in OSX to control them in HWMonitor app, for example?

Is ECWT patched?

Wrong answer. Should be either 'yes' or 'no'... Post your native DSDT.

You should probably read on ACPI fan control. See ACPI spec: http://acpi.info/spec.htm
 
I've found fan performance methods in SSDT-1 at scope \_SB.PCI0.LPCB.H_EC.TFN1 and \_SB.PCI0.LPCB.H_EC.TFN2
How can I use it?

You would have to read the ACPI spec so you understand ACPI programming and start experimenting...
