I am using cpufreqd and it helps quite a bit, but my fan is still noisy and as the OP it is ON even when the laptop is not noticably hot. I have: $> cat cooling_mode <setting not supported> cooling mode: critical $> cat trip_points critical (S5): 90 C That 90C was 88C before I tried this command: /proc/acpi/thermal_zone/THM# echo 90:0:70:0:0 > trip_points So this command did not give different trip points, only the critical value was changed. How do I set the cooling mode and/or the trip points? ->HS -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
