Including FreeBSD 11.0-CURRENT #28 r286232: Mon Aug  3 16:55:05 CEST 2015 amd64, I can
bring down any of my CURRENT boxes (>= IvyBridge) by the issue of

sysctl -a|grep tempe

for looking after the recent temperature (all kernel have the Intel specific driver for
the temperature senors compiled in, like

[...]
coretemp0: <CPU On-Die Thermal Sensors> on cpu0
est0: <Enhanced SpeedStep Frequency Control> on cpu0
coretemp1: <CPU On-Die Thermal Sensors> on cpu1
est1: <Enhanced SpeedStep Frequency Control> on cpu1
coretemp2: <CPU On-Die Thermal Sensors> on cpu2
est2: <Enhanced SpeedStep Frequency Control> on cpu2
coretemp3: <CPU On-Die Thermal Sensors> on cpu3
est3: <Enhanced SpeedStep Frequency Control> on cpu3


I haven't tried issuing the crashing command with kernsl without this module compiled in.
