replaced motherboard in Asus UX31A leads to fan spinning issue

Hi.

I have an ASUS UX31A laptop and recently replaced a motherboard in it. After clean reinstall of arch (UEFI is a bitch!) I found out that my fan won't stop and the laptop won't suspend when the lid is closed. While I can live with manual suspends, the constant high-pitch noise from the fan is driving me insane. Here's what lm_sensors sees:

[cra@momo]::[12:33:11 v06[m02]/Feb07] (master) ~
 $ sensors
asus-isa-0000
Adapter: ISA adapter
cpu_fan:     25500 RPM
temp1:        +39.0°C  

acpitz-virtual-0
Adapter: Virtual device
temp1:        +39.0°C  (crit = +108.0°C)

asus_fan-isa-0000
Adapter: ISA adapter
CPU Fa:      6341 RPM  (min =   10 RPM)
gfx_tem:       +0.0°C  (crit =  +0.1°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +40.0°C  (high = +87.0°C, crit = +105.0°C)
Core 0:         +38.0°C  (high = +87.0°C, crit = +105.0°C)
Core 1:         +32.0°C  (high = +87.0°C, crit = +105.0°C)

Running pwconfig and just accepting all the defaults gives me /etc/fancontrol file but when I try to run fancontrol itself, I get this:

[root@momo cra]# fancontrol 
Loading configuration from /etc/fancontrol ...

Common settings:
  INTERVAL=10

Settings for hwmon3/pwm1:
  Depends on hwmon0/temp1_input
  Controls hwmon3/fan1_input+hwmon2/fan1_input
  MINTEMP=40
  MAXTEMP=70
  MINSTART=150
  MINSTOP=100
  MINPWM=0
  MAXPWM=255

Enabling PWM on fans...
Starting automatic fan control...
Error reading PWM value from /sys/class/hwmon/hwmon3/pwm1
Aborting, restoring fans...
Verify fans have returned to full speed

Here's whole pwmconfig interaction, any ideas what shall I do to make the fan sane?
