RehabMan, success!!!
I ended up deleting my PTID device. It wasn't doing anything.
I installed your ACPI Debug kext and I found out that even GFAN method wasn't running. In fact, the methods on the PTID device weren't running either. I set many debug messages and they didn't appear on the sys log.
I even tried calling GFAN from the PINI method and then I got a message on the log.
My solution was inspired from you. I used the Acer patch, but in the FAN0 method, I used the TH00 and TH01 values from ECOR (the name of my EC) and voila, success!
I didn't need (at least not right now) the other sensors nor the fan control, so I deleted the other methods because HWMonitor already detects my CPU cores temps and the thermal zone, too. Because of I already had a "Fan RPM" device from PTID, I deleted the whole device as well.
In conclusion, here's my modified SMCD device:
Code:
Device (SMCD)
{
Name (_HID, "MON0000") // _HID: Hardware ID
Method (FAN0, 0, Serialized)
{
Store (B1B2 (\_SB.PCI0.LPCB.EC0.TH00, \_SB.PCI0.LPCB.EC0.TH01), Local0)
If (LEqual (Local0, 0xFF))
{
Store (Zero, Local0)
}
If (Local0)
{
Store (0x80, Local1)
Store (0x02, Local2)
Multiply (Local1, Local2, Local3)
Multiply (Local0, Local3, Local4)
Divide (0x03938700, Local4, Local5, Local6)
Multiply (Local6, 0x0A, Local6)
Store (Local6, Local0)
}
Return (Local0)
}
}
I had to modify the formula to calculate the RPM because it appeared to spin at 600 RPM aprox. So, I used the formula on GFAN method and works fine. I have the same readings like on AIDA64 on Windows 8.
I also have some conclusions on the behavior of my fan:
1. At idle and when the temps are below 50 degrees celsius, the fan turns OFF. I see a hyphen on HWMonitor. Over 50 it start spinning at about 1900 - 2200 RPM. It can even reach 3400 RPM under heavy load.
2. The previous statement of the fan turning off it's verified because I don't hear a thing on my laptop, but as soon it turns on, I hear it. It's very quiet, but I hear it.
3. On windows happens the same, but I don't think the fan turns off maybe because it always have some kind of load (I test the fan on AIDA, maybe the program running has some load and causes the fan to turn on).
4. A very strange thing happens when I restart Windows to boot on OS X. The fan starts spinning VERY LOUD and I can check that it runs at aprox 5400 RPM. By rebooting back to windows, the fan stays loud and I can confirm that speed. I have to turn off the system to reset the fan speed.
That behavior I don't remember to have experienced on Windows by playing games with Optimus enabled. I thing it started spinning loud when the laptop is hot enough, but I can't confirm it. I'll play a game or something to see that. On OS X, running Geekbench I get up to 75 degrees and the highest speed I get is 3400 RPM.
Please let me know your opinion, and thanks again for your support, you're a true DSDT master!
Cheers!
