I now made some progress on this. I found out that in single user mode, the fan stop when the machine is idle, even with acpi enabled. It turns out that hw.acpi.cpu.cx_lowest gets changed from C1 to C2 when going to multi user. If I set it back to C1 the fan will stop and only start again when the machine gets busy. However, if I pull the power, hw.acpi.cpu.cx_lowest changes to C2, and the fan starts running againg and will not stop, until I change it back to C1 manually. Does this make any sense? -- Christian LaursenReceived on Sat Aug 28 2004 - 21:02:25 UTC
