Speedfan doesn't recognize correctly the CPU temp, but I think the autor will fix the problem soon.

However the good news is that speedfan recognize the embedded controller that control the fan!
The fan is not hardware controlled but software controlled (with a registry key in the bios CMOS, that change its value according to the CPU temp sensor), and that you can change cecking the option "Fan always on" in the program Acer e-settings.

If we are able to control the embedded controller with a software, we are able to turn off the fan!

The embedded controller is a National Semiconductor PC87591L as you can see from this screen of speedfan.



I hope the author fix the problem soon! Please report him the problem!!!

bye

Hmm.. As I wrote the 62°C is after running a CPU intensive program for some time. If I play a game it can be >70°C - plus I have verified the temperature with an infra-red thermometer.

I have installed SpeedFan under Win XP x64! There it shows the right Temperature like MobilMeter!

The Tool is free and not even more only for Centrinos! In the next Version you can control fan speed! Hope these are good news!

Ok, back online with the Ferrari 4006 here.

Got it back from repair shop in Germany after 2 weeks, a note together with the notebook said they had replaced the M/B - motherboard...

And the Bios was back to 3A19!

Still with a constant high annoying fan noise !!!

I updated the Bios to 3A23, still no improvement...

(Another thing that got me disappointed was that they did send the Ferrari box back uncovered with scrapes all over the place) a minor issue that I could have lived with if just the fan problem had been resolved....but no!

Now I have to get in contact with Acer again - and then take a decision if I should return it or not.... besides from this major flaw I'm so pleased with the machine.

Acer Design Fault

I just bought a new Acer Aspire 5670 with ATi X1600, which has exactly the same problem (and same reply from Acer Hong Kong Service). The fan noise is driving me nuts, but they refused to give me back the money. I noticed people who bought this model before Sep tend to complain only about the hot pad (I also tired myself before) when it came with X1400. On mine the pad is cool, clearly showing that Acer is aware of the heat problem and chose to "solve' it at the expense of fan noise.

My advice to all here: NEVER again buy any 2nd line brand PCs, consider only the "A" brands like HP/Sony/Apple/Fujitsu/Samsung. It's in the details (incl after sales service) that really matter!

I said I had a couple of other Acers that are sooo quite compared to mine, that the fan speed on mine never changes no matter what I do with the laptop in regard to load / heat

I also stated that there a quite a few people on the net complaining about this, and that some people have very quiet Ferrari laptops, while others think they are way to loud.

Anyway they are going to "service it", check for dust, sensors etc. I doubt this will help. My next course of action will be to send a letter to Acer Aus on letterhead stating that I think there is a manufacturing issue, (maybe there are two fan module suppliers?) and that they need to resolve it.

What would really help me is someone else in Sydney with a Ferrari that thinks their fan is very quiet so I can do a realistic demo for them!

Steve

Hey there is an new update of NHC! http://www.pbus-167.com/nhc/nhc_advanced_new.htm it is an update for Core Duo, but the programer write, that there are new functions to read out embedded controller (http://www.p35-forum.de/board/thread...7649#post47649) it is in german, I know! Has somebody of Ferrari 4000-Users here knowlege about writing an ACPI-File for that Lappi? I think the solution to stop the fan is near, but we need an ACPI-script to control the fan over embeddedcontroller! The .dsl-File of the Lappi shows, that you can´t control the fan in an easy way; there is not much in the "Thermal Zone" so I think the fan of the Ferrari is Hardware-controlled by embedded controller!

So every man with Ferrari 4000 model, who want to chage the fanspeed, think it over! Maybe we find an solution to do it!

just a wild shot in the dard here, have u tried to look into services area, and disable some of them? i personally would not know what, since i do not own this model, but amd machines. Also, AMD drivers?
