CPU fan is always at maximal speed
Hello.
I'm new in Solaris 10 Developer Edition.
I've installed it on my Acer Aspire 1710 laptop.
To install successfully, I've constrained to pass "user-acpi-options=0x2" to the kernel due to "probably" a bad compatibility of ACPI Management and my computer.
Since, Solaris runs very good.
The only small problem is that the CPU fan cooler runs away at maximal speed from login to shutdown.
Can someone tell me if there is a command to pass to the shell to manage the speed of the CPU fan more accurately ?
Thanks a lot.

Laptops usually have automatic fan speed control.
If it runs on maximum, that means your CPU is overheating.
If you live in warm country, that could explain it, buy special cooling plate for your laptop with fans, it should solve this problem.
Btw, what CPU do you have? (Maybe power saving of this CPU is not supported by Solaris, and it does not send HALT commands to it).

First, thanks a lot for your response.
My laptop is an Acer 1710 with an Intel Pentium 4 Processor with Hyper-Threading Technology 3GHz/1Gb RAM.
In order to install and run Solaris, I must pass 'user-acpi-options=0x2' to the kernel (via Grub) because Solaris won't boot. I know this is related to power management, but I've no other option because there's no item related to ACPI in the BIOS. So, I can't disable it and I must pass this parameter.
Before installing Solaris, this computer runs Windows XP Pro and Linux Suse Professional and no "fan problem" appears... The two OS controls speed of the fan accurately. For my localization, I live in Belgium which is not too hot (20-25癈 in summer). I don't know if a method exists to view temperature of the CPU ?
Thanks.
