I currently have Slackware 10 (upgraded from 9.1 with swaret) on my HP Pavilion ze4420us laptop. I have compiled a 2.6.7 kernel with all of the ACPI support.
When I boot up the computer, the fan isn't running; it doesn't start running until a few minutes after I login to gnome. After turning on, the fan won't turn off. The fan has 3 speeds. If I'm compiling or doing some other CPU intensive work, it quickly goes up to the highest speed. When it finishes compiling, it will return to the low speed after it cools down, but it never turns off. If I boot to Windoze, the fan will turn off when I'm not doing any CPU intensive work. I've experimented and the fan will turn off in Linux after holding it up to an A/C vent for a few seconds.
Logged into a gnome session,
reports a temperature of 51C when I'm not doing anything.
My question is does a Linux system tend to be using the CPU more than Windoze when doing little or no work? Or, does Windoze not turn the fan on unless the temperature is higher?
Thanks for anyone's input!
