Hi, >cat /proc/acpi/thermal_zone/THR1/trip_points >critical (S5): 95 C >passive: 88 C: tc1=2 tc2=3 tsp=50 devices=0xdf64a940
This means, that you don't have fan control (i.e. active cooling) through ACPI functionality - only passive cooling (i.e. decreasing frequency, using throttling) is possible for this thermal zone. So, in this string >echo 100:0:50:80:70:50 > /proc/acpi/thermal_zone/THR1/trip_points the only meaningful values are the first and the third (but at least 5 trip points are required - <critical>:<hot>:<passive>:<active0>:<active1>) Regards.
