Hello all

i got a new Acer Aspire 2920z. Since i still dont like Vista i decided
to try to install Windows XP. It seems to work fine. All drivers all
available. CPU is a dual-core T2310 @1.46Ghz.
Until some 2 days after installation CPU throttling worked fine -
usually running at 790Mhz. Then suddenly i noticed that the Fan is
running noticably more often and longer. I checked and the reason is,
that the CPU ist always running on full speed: 1460Mhz. I checked in
"System" and with "RightMark CPU Clock Utility". Even on long 0%-usage
times, it's never clocking down.

Where do i have to start looking? what could be the reason for this?
Chipset is Intel GL 960, i've already reinstalled Chipset-Drivers. But
actually i thought CPU Speed is controlled by Hardware or BIOS.

Thanks for any hint. it's really annyoing and i absolutly dont want to
restore Vista...

The speed is controlled by the software control program. You need to find
the one from Acer and install it.

thanks. meanwhile i installed rightmark cpu clock utility, the newest
version wich is supposed to be able to control core2duo.
SuperPi in Powersavings-Mode: 31s
SuperPi without Powersavings: 18s

so rightmark clock is working

but it still doesnt really switch off the fan. i called acer support.
they got annoyed, told me that in this small formfactor it's always
dificult to get air out, and you'll always have noise. i somehow cant
believe this. i'm shure there was less fan-movement in the beginning.
i mean, the thing is running at 550mhz all throttled down, 36degrees.
i cant imagine that the fan has to run all the time. i mean, for
traveling i had a compaq with a pentium 2 at 600mhz. usually there was
not a single noise from this thing. i think thermals on a c2d@at
550mhz should be even better. is it true that it's normal that the fan
is always spinning in this 12" laps?

he didnt say anything about a control app. i told him, i've windows xp
on it and am thinking about recovering to vista, just to check. he
said it wont make any diference. i dont trust these guys...

any hints what to do? or where this acer-tool is at?

Pretty much. Mine will shut down if I'm doing nothing, but it never
stays off for long.

Possibly. It's not necessarily a bad thing either, since it may keep
the innards of the whole laptop cool.

I have a relatively recent Gateway laptop (dual Athlon) whose fan always
seems to be running. Most of the time it's at low speed and almost
inaudible, but if I run something CPU-hungry for extended periods the
fan switches into high for a while. The fan air is drawn into the case
from a bunch of different holes and slots before going through the CPU
heatsink and out the side of the case. This constant airflow through
the case seems to keep everything relatively cool, which is good for the
life of the components.

In comparison, I also have an older Dell with a Pentium III CPU. Its
fan is normally off, and when on it draws cooling air only through the
CPU heatsink via case slots near the heatsink. So there's no cooling
airflow through the case, even when the CPU is hot enough to turn on the
fan. After a while with the laptop turned on but not doing much, the
case gets fairly warm on the outside, with hot spots adjacent to the
disk, on the memory access door, etc. That will eventually reduce the
life of the drive and motherboard. (The life of electrolytic capacitors
is cut in half for every 10 degrees C rise in temperature).

Here is the thing: you might want your CPU to run at 790Mhz. When your
CPU demand increases, your CPU speed will increase to satisfy your demand.

Now, you do not expect your CPU to be running at top speed, so you need
to check what applications are running that are demanding that CPU
speed. Right-click your taskbar in a blank area and choose Task
Manager. See what applications are consuming your CPU and report back here.

Q

well, that's the point. it's running on 0-3%. there's really nothing
extraordinary running. now i get it to clock down, but the fan is
still venting all the time

Hi,

I also got a Aspire 2920z, where did you get XP drivers?

I did't have any fan problems on vista and on Ubuntu I use "sudo
cpufreq-set -g ondemand" with no problems.

Thanks.
