acpi and cooling cpu

[Sarrkazztic]

Is it possible that if you disable acpi and go to standard pc that the computer could run several degrees celcius cooler than under acpi? also If I go back to the standard pc mode how can I make the computer automatically shutdown.

I set it to standard pc last night and it did run several degrees cooler but I do not know why does anyone have an answer for this and also the shutdown issue can I make it auto shutdown without acpi enabled

does making sure APM is enabled in Power Options in the Control Panel not work for you? jmarcus suggested this when you asked the question back in April:
http://discussions.virtualdr.com/For...ML/004268.html
this is generally how autoshutdown is accomplished in Win2k under the standard pc HAL.

as for the temperature, as far as i know, there shouldn't be any inherent differences in temperature between ACPI and Standard but maybe some other power-management settings shifted in the change? things like time before the hard drive spins down and the like? that could definitely affect temperature. also, if any BIOS settings changed (esp. pertaining to power management and/or fans), temperature changes might result. just guesses however.

I'm sorry since this is a totally different computer and different situation totally I did not realize that the old topic even had anything to do with this one...I was just asking advice.
The real purpose of this post is to find out if there is something involved in the acpi management that would make the cpu work harder than if the motherboard itself is in charge of IRQ settings and power options. I will do more research on this topic but what I have found so far implies this to be correct at least with my system. If disable acpi and set up the standard pc setup the machine not only sets up all my devices on their own IRQs but the cpu temps range between 5-10 degrees celcius cooler than when I have acpi enabled and let the O.S. handle everything. Again I am just looking for an educated opinion on this as a way to either backup my findings or disprove them to coincedence.

part of this is a hardware issue but I wanted to post it in this forum because it is technically correct to be here since the acpi is based in win2k.....here is a little more of what I have found....under acpi Sisoft Sandra cannot read temperature values on my motherboard but hardware monitor can....when I disable acpi and rebooted after letting the O.S. reinstall all the hardware and assigning new IRQs then Sandra could read temps and also the machine ran cooler...I then found that what I was actually trying to cure (sound card sharing same irq as video card and nic and sound was scratchy in tigerwoods golf 2000) did not solve the problem so I went back in an enabled acpi and let it reinstall everything again but now Sandra cannot get temps again and the system temps are moderately higher when doing the same activities as before....

acpi and those type programs run in the background thus put a load on the cpu.
Normally, when you disable it, you have to treat it like a AT motherboard even if it is a ATX.
It will require us to turn it off manually.

Far as I know that is the way it is set up.

Train it sounds like you use this setup is this correct."It will require us to turn it off manually"

If so what do you think is the gains of lower temps more of a benefit than having the computer shut itself off?
