#86 Thanks. I thought just sudoing the command was enough.

Alas, still no luck in turning off the fan after suspend. I tried few combinations of these commands:
echo -n "0" > /sys/devices/virtual/thermal/cooling_device0/cur_state
echo -n "0" > /sys/bus/acpi/drivers/fan/PNP0C0B\:00/thermal_cooling/cur_state

, but they seem to have no effect on the fan. I tried the script in #82 as well without success.

After resuming from suspend the sensors command shows clearly that one temperature is high, although it really is not, and that fires the fan I guess:
root@ENVY14:~# sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +47.0°C (crit = +120.0°C)
temp2: +89.0°C (crit = +127.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +49.0°C (high = +86.0°C, crit = +100.0°C)
Core 0: +49.0°C (high = +86.0°C, crit = +100.0°C)
Core 1: +50.0°C (high = +86.0°C, crit = +100.0°C)
Core 2: +47.0°C (high = +86.0°C, crit = +100.0°C)
Core 3: +47.0°C (high = +86.0°C, crit = +100.0°C)

Before a suspend the temp2 shows usually a value similar to temp1. Does someone have suggestions what I could research next?
