8710w - fan works all the time - SOLVED

[msk_sk]

Regarding this thread:
8710w - fan works all the time

This is due to error in DSDT table.

Check large gap between "fan speed up" temperatures - red line, and "fan speed down" temperatures - blue line:
Upnito.sk - populárny hosting súborov a obrázkov

Corrected temps are shown here:
Upnito.sk - populárny hosting súborov a obrázkov

And how to slow down your fan?

1. Run CPUID HWmonitor and see GPU temp TZ2_ and fan speed percentage TZ5_

2. Then Merge this corrected reg file for 8710w, BIOS F.20, W7 64bit Ultimate:
http://download.hellshare.sk/nc65xx-...1-rar/6263784/

3. Reboot

4. Run CPUID HWmonitor, see temps, hear the fan and let me know.

Hi thanks for this but the reg file is impossible to download for me...
Could you send it another way than HELLSHARE ?
Thanks.

Contrary to the OP's post, you may want to avoid the F.20 bios if want the modded SLIC 2.1, no-whitelist and dual-IDA functionality of the previous F.0F release here. HP have set a trap so can't flash back to the older version to get that functionality, plus they've increased the bios revision so as to make it look like it's a lot newer than previous versions. Crafty.

Thank you for the new link.
But, for the fan, nothing's changed...

Thank you for the new link.

Please let me know your GPU temp TZ2_ and appropriate fan speed percentage TZ5_ values. My TZ2_ is about 53 Celsius and TZ5_ is 30 precent.

Which version of BIOS and Windows do you use?
If you run Regedit, do you see folder HKEY_LOCAL_MACHINE\HARDWARE\ACPI\DSDT\HP____\nc65xx\ or something else?

Hi, thank you again,
CPUID says :
Temperature 0 51°C (123°F) [0xCAA] (TZ2_)
Temperature 3 70°C (158°F) [0xD68] (TZ5_)
(I don't know how read this..)

I'm using windows 7 64 Ultimate with a F.20 bios on a 8710w with a core 2 duo T7700 cpu and nvidia quadro fx 1600m.
My laptop worked fine with the f.0E bios...

At first, TZ5_ is not temperature but actual fan speed percentage. 30 is silent, 50 little noisy, 70 and above like vacuum cleaner.

After install W7, drivers and nVidia driver, you have to do this:
How to Reduce Fan Noise on HP Notebooks: Patching the DSDT table
But do steps 1 to 8 only.

Then open dsdt.ASL in editor, show line numbers and change values as follows:
line 13315 0x5ac,
line 13316 0xc6e,
line 13317 0xcbe,
line 13318 0xd04,
line 13319 0xd5e,
line 13320 0xdb8,
line 13321 0xe1c,
line 13322 0xe6c

line 13326 0xc6e,
line 13327 0xcf0,
line 13328 0xd36,
line 13329 0xd90,
line 13330 0xdea,
line 13331 0xe4e,
line 13332 0xe94,
line 13333 0xfa3

Continue with steps 13, 14 and 15.

Thanks again,
I've done this.
The equus.exe link has been hard to find (i've found the version 0.01 alpha)
but Fan still works all the time...
I'll retry this tomorow...

When you compile dsdt.asl back to dsdt.aml (step 14) you can ignore the warnings, but if you get errors, go back and check your syntax. If you get "error: expecting Symbol '('" the number in the brackets is the line number, go to that line in dsdt.asl and add a pair of bracket () to the end of the previous line, I had to repeat this 3 times before it will compile:
line 14087 C381()
line 14781 \_TZ_.C381()
line 14871 \_TZ_.C381()
