How can i disable temperature protection in ubuntu 9.04 ?

My laptop ASUS F3E sometimes shutting down after critical temperatute reached...

from kern log:
Aug 18 15:49:20 luki kernel: [42332.730718] ACPI: Critical trip point
Aug 18 15:49:20 luki kernel: [42332.730737] Critical temperature reached (90 C), shutting down.

cat /proc/acpi/thermal_zone/THRM/trip_points
critical (S5): 90 C
passive: 87 C: tc1=2 tc2=10 tsp=100 devices=P001 P002

if my cpu reach 87 C (on playing games .. ), fan is kicked up to full speed, and cpu frequency is set down to 50%...
But sometimes temp reach 90 C and then shutting down....

Is possible tuneup trip_points? set crit. temp to 100C or passive temp to 83C or disable this stupid protection ??

On win xp i don`t have this problem....

temp from acpi and sensors in the same time:
acpi -t
Battery 0: Full, 100%
Thermal 0: ok, 70.0 degrees C
sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +70.0C (crit = +90.0C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +63.0C (high = +85.0C, crit = +85.0C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1: +61.0C (high = +85.0C, crit = +85.0C)
Why are temperatures from acpi and cores not equals?
