8710w - fan works all the time - SOLVED

Wonderful, it seems to work!!
I'll test it longer tomorrow and write you back,
Thanks a lot.

Hi,
I took time to check my system.
It works nice except when I plug my other screen to expand my desktop...but I don't know if it's a new problem because my second screen is new (If you have an idea about that...).
So, thanks a lot for all.

What is the problem with your secondary display?

When I work with my secondary display, when the fan begins to work (5 minutes), it doesn't stop...

You have to check relations between TZ_2 temperature and TZ_5 fan speed.

Your new DSDT table controls fan speed as follows:

When GPU temp raises:
above 45 Celsius = 30% fan speed
above 58 Celsius = 50% fan speed
above 65 Celsius = 70% fan speed
above 74 Celsius = 85% fan speed
above 83 Celsius = 100% fan speed

When GPU temp decreases:
bellow 78 Celsius = 85% fan speed
bellow 69 Celsius = 70% fan speed
bellow 60 Celsius = 50% fan speed
bellow 53 Celsius = 30% fan speed
bellow 45 Celsius = 0% fan speed

Simply, if your GPU is hot, the fan runs faster. I will check my extended desktop and GPU temperature and write you back.

My primary display works with 1920x1200, extended desktop at secondary display 1280x1024. TZ2_ is 58 Celsius and TZ5_ is 50%.

Excuse me but I don't where to find that in HWmonitor ?

Run HWmonitor as Administrator and you can see it.

I also had similar problem on 8710p

The only bios which works fine without this issue is F.0E, they updated something in F.0F (changelog says updating microcode) and ed it up ..

So I'm on F.0E it works fine.

Unfortunately I'm on the F.20 bios, so I can't downgrade the bios.

When the fan doesn't stop, with the second display plugged via HDMI (1920/1080), Hwmonitor says :
