No more CPU throttle on Acer 2920z Ty 01-09-2008

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...

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.
