Yes, is the same situation.
I don't solved the problem. For this reason I post here now. And, I
wait a long time for try new situations and not crossposting the
problem in other mailing list.

First of all, I load the correct ACPI mapping driver for acer laptops
( this situation ):
acpi_wmi(4)
root@casa:/root # kldstat | grep acpi
41 0xc13dd000 462c acpi_wmi.ko
root@casa:/root #
Now I try yours values:
First, de defaults values:
root@casa:/root # sysctl -a | grep hw.acpi.thermal.user_override
hw.acpi.thermal.user_override: 0
root@casa:/root # sysctl -a | grep hw.acpi.thermal.tz0._PSV
hw.acpi.thermal.tz0._PSV: -1
root@casa:/root # sysctl -a | grep hw.acpi.thermal.tz1._PSV
hw.acpi.thermal.tz1._PSV: 95,0C
root@casa:/root # sysctl -a | grep hw.acpi.thermal.user_override
hw.acpi.thermal.user_override: 0
root@casa:/root #
I change to your suggerations:
root@casa:/root # sysctl hw.acpi.thermal.user_override=1
hw.acpi.thermal.user_override: 0 -> 1
root@casa:/root # sysctl hw.acpi.thermal.tz0._PSV=65C
hw.acpi.thermal.tz0._PSV: -1 -> 65,0C
root@casa:/root # sysctl hw.acpi.thermal.tz1._PSV=65C
hw.acpi.thermal.tz1._PSV: 95,0C -> 65,0C
root@casa:/root # sysctl -a | grep hw.acpi.thermal.user_override
hw.acpi.thermal.user_override: 1
root@casa:/root # sysctl -a | grep hw.acpi.thermal.tz0._PSV
hw.acpi.thermal.tz0._PSV: 65,0C
root@casa:/root # sysctl -a | grep hw.acpi.thermal.tz1._PSV
hw.acpi.thermal.tz1._PSV: 65,0C
root@casa:/root #
I look for the temperature at the moment:
root@casa:/root # sysctl -a | grep temperature
acpi_tz1: temperature 67.0C: decreasing clock speed from 500 MHz to 250 MHz
acpi_tz1: temperature 67.0C: decreasing clock speed from 250 MHz to 125 MHz
hw.acpi.thermal.tz0.temperature: 73,0C
hw.acpi.thermal.tz1.temperature: 72,0C
dev.cpu.0.temperature: 75,0C
dev.cpu.1.temperature: 75,0C
root@casa:/root #
I try compile one port ... :
... while compile I look the temperature:
root@casa:/root # sysctl -a | grep temperature
acpi_tz1: temperature 67.0C: decreasing clock speed from 500 MHz to 250 MHz
acpi_tz1: temperature 67.0C: decreasing clock speed from 250 MHz to 125 MHz
hw.acpi.thermal.tz0.temperature: 95,0C
hw.acpi.thermal.tz1.temperature: 94,0C
dev.cpu.0.temperature: 92,0C
dev.cpu.1.temperature: 92,0C
root@casa:/root #
I break the compilation because if hw.acpi.thermal.tz%d.temperature (
of ACPI_THERMAL(4) ) = 100C the FreeBSD shutdown automacally.

On 8.x I get the same problem.
Thanks, see you.
