Dell Vostro 3560 no automatic fan control

Hello,
I own this laptop and i am able to set the fan speed via

This shuts down the fan.

i8kfan -1 0

This make the fan go on full blow.

i8kfan -1 2

Sensors detect everything they should:

[andre@andre ~]$ sensors
i8k-virtual-0
Adapter: Virtual device
Right Fan:   144000 RPM
CPU:          +66.0°C  

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +69.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:         +65.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:         +69.0°C  (high = +87.0°C, crit = +105.0°C)
Core 2:         +61.0°C  (high = +87.0°C, crit = +105.0°C)
Core 3:         +64.0°C  (high = +87.0°C, crit = +105.0°C)

/etc/i8kutils/i8kmon.conf:

# Sample i8kmon configuration file (/etc/i8kmon, ~/.i8kmon).

# Kernel I8K status file
set config(proc_i8k)	/proc/i8k

# Kernel APM status file
set config(proc_apm)	/proc/apm

# Kernel ACPI status file
set config(proc_acpi)	/proc/acpi/ac_adapter/0/status

# External program to control the fans
set config(i8kfan)	/usr/bin/i8kfan

# Applet geometry, override with --geometry option
set config(geometry)	{}

# Run as daemon, override with --daemon option
set config(daemon)	0

# Automatic fan control, override with --auto option
set config(auto)	0

# Report status on stdout, override with --verbose option
set config(verbose)	0

# Status check timeout (seconds), override with --timeout option
set config(timeout)	5

# Temperature display unit (C/F), override with --unit option
set config(unit)	C

# Temperature threshold at which the temperature is displayed in red
set config(t_high)	80

# Minimum expected fan speed
set config(min_speed)	1800

# Temperature thresholds: {fan_speeds low_ac high_ac low_batt high_batt}
# These were tested on the I8000. If you have a different Dell laptop model
# you should check the BIOS temperature monitoring and set the appropriate
# thresholds here. In doubt start with low values and gradually rise them
# until the fans are not always on when the cpu is idle.
set config(0)	{{- 0}  -1  60  -1  65}
set config(1)	{{- 1}  55  70  55  75}
set config(2)	{{- 2}  60  80  65  85}
set config(3)	{{- 2}  70 128  75 128}

# end of file

This:

i8kmon --daemon

Keeps running, but the fan is on full blow no matter what.

I have added this service to systemd and it gets loaded okay,
but it runs the i8kmon --daemon, which does nothing.

Any hints?
Thanks

Re: Dell Vostro 3560 no automatic fan control

Stupid me, it was:

# Automatic fan control, override with --auto option
set config(auto)	0

Set it to 1 and it's done.

This is hardware design problem.

Re: Dell Vostro 3560 no automatic fan control

I have a dell vostro 1710, no fan running at all!
I have opened it, and saw it spinning for a while on notebook power on, so it looks like it works
Do not remember if this is happening a long time ago, or maybe after a Syu... but now temp is on 62 doing stuff, 74 watching a video..... it will be more than 80 in summer? lol

Will install and configure i8kutils I guess....
