G51J Intel PM55 Chipset - Fan Control Possible?

We have observed that during many games, the temperatures cycle because the fan does not stay on high consistently.

This is bad for the hardware and contributes to high temperatures.

What are the chances that we will see a fan control utility for the G51J / G60J, and possibly other G series notebooks?

I understand that often devs don't want people to lower the fan speeds and fry the laptop, but I get fustrated when devs think that a quiet laptop that will fry itself is a better idea than conservative fan speeds.

Marketing > Common Sense.

And this isn't an attack on ASUS, most laptop companies I have encountered do this (Clevo comes to mind as an exception, but just outside of my price range).

 

+1 I'm wondering the same for my G51J. The 260GTX runs very warm.

 

Chances are zero or close to it.

 

I would love this ability personally for my G51VX. Chances are slim though as we never even saw a utility for the G50.

 

I don't expect any help from ASUS themselves, however...

Speedfan and like programs support specific chipsets / ACPI's.

Would it not be possible for someone to support the PM55? I believe this chipset is used in a wide range of hot running laptops (i7 + high end GPU).

I notice most fan utilities access desktop fans, but few mobile MOBOs are supported.

Why is that? How can I help with the development of PM55 support?

 

Shameless bump... this would help so many users out there...

 

It will probably never happen because Asus is afraid of all the RMAs their going to have to do with if they released a tool to manually adjust fan speed.

 

I think it is a part of the BIOS and maybe even a completely separate circuitry. Basically there might be no way to control the fan through the software, just like the LEDs on G51/G60.

 

i think its possible to control fan by change of temperature reading

 

Hey now this is clever!!

The question: how to change the temperature bias of the hardware sensors?

Would I be able to compensate for this change in something like HW monitor, where I could see my real temps while my laptop is worrying that it is just about to buy the farm?

 

Its not possible. If you want the fans at 100% you should put your notebook on top of the stove

 

you might be able to change the temperature bias (or 'compensation' in the newest nibitor) to skew your GPU temps. i don't know if it applies to mobile cards, and it won't help in this case as the GPU only sets the fan in one of three states on opposite sides of the speed scale (i'll number them 7 as idle and 1 as the max) - down to 7 at 70c, down to 2 at 89c, up to 2 at 88c and up to 1 at 93c. the intermediate values are all controlled by the CPU.

from help:

 

Oh wow that's very helpful. What about skewing your cpu's temps? Or would I need to be writing a bios update for that sort of thing. I get the feeling this whole idea would cause more problems then it is worth.

 

CPU-based fan speed depends on THRM (as reported by the BIOS and HWmonitor among others). with enough dedication and work with a disassembler/debugger you could probably add in a bias to asus' ACPI driver to report a higher temp, but that one might have it's roots a little deeper. way more trouble than what it's worth is probably right.

 

its possible see this http://forum.notebookreview.com/asu...-asus-g51jx-owners-lounge-25.html#post6453068

 

can you please create me 1 RW file for 50% and 70% speed fan?thx in advance

p/s: i might just code a program for controlling fan based on your script
