Not working for me and i think this will not work on his pc.

 

From what i read:

 

I found that the gpu is controlling the fun speed.

Some asus laptops have 2 fans, 1 cpu and 1 gpu, but this is not the case.

The problem is that the gpu is off, so there s an error and the fun does not know what to do (stuck at 100%).

This happens when the off method is called, you have to completely shutdown the pc to reset the fan.

There s no method to control the fun on asus laptops, it should be in _SB.PCI0.LPCB.EC0 or _SB.PCI0.SBRG.EC0, but you can find a device named PTID (dsdt on my lap) and seems that patching this device should fix the problem.

 

These are speculations and i don t know how to patch the device or if this is the right device to patch.

I also found these infos... 

The Fan-Patches for some Acer and HP Laptops contain solutions for that, but they cannot be used for your ASUS laptops.

after 30+ minutes of tests and kernel panics i made a working patch

 

it should work for his dsdt and maybe other laptops. (seems my acer laptop has the same problem when you disable the gpu)

 

My DSDT has 2 methods in EC: TSDS AND TSES.

 

Here i m calling TSDS because is the one called from _PS3 before calling DOFF and _OFF.

 

**You may need to change EC to EC0, and TSDS to the method called in your DSDT/SSDT**

into method label _INI parent_label _SB.PCI0.PEGR.GFX0 insert
begin
_OFF ()\n
^^^LPCB.EC.TSDS ()\n
end;

into method label _REG parent_hid PNP0C09 insert
begin
If (LAnd(LEqual(Arg0,3),LEqual(Arg1,1)))\n
{\n
    ^^^PEGR.GFX0._INI ()\n
}\n
end;

# THESE SEEM NOT NEEDED ON MY DSDT, THEY DON T RUN.
# SO YOU PROBABLY NEED TO CHANGE _OFF TO _INI (CANNOT TEST HERE)
into method label _PTS code_regex ([\s\S]*) replace_matched
begin
External(\\_SB.PCI0.PEGR.GFX0._ON, MethodObj)\n
If (CondRefOf(\\_SB.PCI0.PEGR.GFX0._ON)) { \\_SB.PCI0.PEGR.GFX0._ON() }\n
%1
end;

into method label _WAK code_regex (Return\s+\(.*) replace_matched
begin
External(\\_SB.PCI0.PEGR.GFX0._OFF, MethodObj)\n
If (CondRefOf(\\_SB.PCI0.PEGR.GFX0._OFF)) { \\_SB.PCI0.PEGR.GFX0._OFF() }\n
%1
end;

i attached a dsdt here

 

no patch to check the fan speed yet but...

 

you can hear the fan, especially if you run a game, it will spin faster.

hwmonitor, your cpu should not overheat instantly on heavy usage

 

 

you should also try the sleep mode to check if you need to patch the wake up

 

EDIT:

the code is here

maybe you do not need to patch WAK and PTS, our DSDTs are almost identical, and my DSDT does not need that patch, you should test it.

Some patches rename EC0 to EC so you must use the correct name.

TSDS is an EC0 method and you can find a call to it in the _PS3 method of your GFX0.

If you have a different method name you have to change that.

(Not your case)

Pwr to fix instant wake.

It may or may not work for you.

 

Disable sip (0x67),

Compile the kext with xcode

sudo chown -R root:wheel kextname

sudo chmod -R 755 kextname

sudo kextload kextname

See readme for more info.

 

Try fix shutdown in clover.

 

Afaik other oses are not affected by clover patches/injection.

 

You were probably using the old dsdt and you did a reboot to windows (shutdown is required to reset the fan)

Here you go

https://github.com/RehabMan/Laptop-DSDT-Patch/tree/master/usb

 

About gpu patch, as pointed out by rehabman this is a better way to do it:

(See my example code)

Move the call to TSDS () from _INI to _REG and remove the call to _INI in _REG.

 

You need to disable sip to load the kext, you can temporarily disable it in clover bootloader.

Press O and go to system variables, set csr to 0x67.

No, i mean, you turn on the pc, clover will boot (unless you are using the quick boot, so you need to press a key to show clover) and there press O.

Clover menu will appear

bash-3.2#

Is it full speedstep? also i wonderwhy can't check speedstep with method using Console app with AppleIntelCPUPowerManagementInfo.kext?

Forgot, i'm using Sierra. Maybe cause is AppleIntelCPUPowerManagementInfo.kext not support Sierra yet,right??

That code is needed if your laptop does not turn on after sleep

Try to close your lid and if you can t wake the pc you need this patch. (You probably need to fix that code if the fan is stuck at 100% on wake.)

 

Speedstep seems fine.

Dunno why, i use that kext.

 

AppleIntelCPUPowerManagment is an apple kext.
