CPU fans doesn't work in OS X

[Mihael]

Hello!

 

Can anyone help me to run laptop fans in OS X? In windows they work only with intel thermal driver.

I found fan devices in DSDT and SSDT-1 but can't start fans, don't know what the command needed to start them.

Simple \_TZ.FN00._ON() doesn't work.

 

In attach DSDT and SSDT-1.

                            If (LEqual (One, THOF))
                            {
                                \_TZ.FN00._OFF ()
                            }

The bit THOF located in GNVS memory

    OperationRegion (GNVS, SystemMemory, 0x5EF8A000, 0x02B1)
    Field (GNVS, AnyAcc, Lock, Preserve)
    {
        OSYS,   16, 
....
        THOF,   8, 
        ACT1,   8, 

That usually means set by BIOS.

There may be another problem, if the address of GNVS shifted compared to your saved DSDT.
