If temperature is the concern, you could override passive cooling threshold by putting something like hw.acpi.thermal.user_override=1 hw.acpi.thermal.tz1._PSV=75C into your /etc/sysctl.conf You will need to figure out which thermal zone you need to override _PSV for (in my case tz1) and what do you want to cap temperature at (in my case 75C) HTH, -- Alexandre "Sunny" Kovalenko (Олександр Коваленко)
