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)
