My question is: Does it actually makes any difference in power consumption? I raise and lower the clock speed (via sysctl ACPI MIB stuff) according to use. The system does in fact feel correspondingly faster or slower. However, once the fan comes on, it never goes off again and I can't seem to override this via sysctl. Is this just T40 ACPI BIOS bogosity (running 2.02 I think)? I just seems like fan power consumption would be the big hog on an otherwise idle system.
