ASRock Z68 Pro3 Gen3 - no fan control

Hi guys,

Is anyone else running with one of these boards?  I've been trying to get the fan control to work (right now the fan just runs full-on at all times), and have so far met with failure.  I've followed the instructions on the lm_sensors page, and here is what is currently output by 'sensors':

radeon-pci-0100
Adapter: PCI adapter
temp1:        +73.0 C  

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +41.0 C  (high = +80.0 C, crit = +98.0 C)
Core 0:         +41.0 C  (high = +80.0 C, crit = +98.0 C)
Core 1:         +39.0 C  (high = +80.0 C, crit = +98.0 C)
Core 2:         +37.0 C  (high = +80.0 C, crit = +98.0 C)
Core 3:         +38.0 C  (high = +80.0 C, crit = +98.0 C)

nct6776-isa-0290
Adapter: ISA adapter
Vcore:         +1.05 V  (min =  +0.00 V, max =  +1.74 V)
in1:           +1.86 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
AVCC:          +3.34 V  (min =  +2.98 V, max =  +3.63 V)
+3.3V:         +3.34 V  (min =  +2.98 V, max =  +3.63 V)
in4:           +0.15 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
in5:           +1.68 V  (min =  +0.00 V, max =  +0.00 V)  ALARM
3VSB:          +3.47 V  (min =  +2.98 V, max =  +3.63 V)
Vbat:          +3.30 V  (min =  +2.70 V, max =  +3.30 V)  ALARM
fan1:         0 RPM  (min =    0 RPM)  ALARM
fan2:            0 RPM  (min =    0 RPM)  ALARM
SYSTIN:        +41.0 C  (high =  +0.0 C, hyst =  +0.0 C)  ALARM  sensor = thermistor
CPUTIN:        +36.5 C  (high = +80.0 C, hyst = +75.0 C)  sensor = thermistor
AUXTIN:        +20.5 C  (high = +80.0 C, hyst = +75.0 C)  sensor = thermistor
PECI Agent 0:  +39.5 C  
cpu0_vid:     +2.050 V

The driver, BTW is 'w83627ehf'.  Anyhow, since the RPM on both fans is 0, again following the instructions I modify /etc/sensors.d/sensors.conf to modify the fan speed divisor:

chip "w83627dhg-*" "w83667hg-*" "nct6775-*" "nct6776-*"
...
set fan1_div 4
...

This just results in the following error from 'sensors -s':

Error: File /etc/sensors.d/sensors.conf, line 330: Unknown feature name
nct6776-isa-0290: No such subfeature known

which has left me at a dead end.    Also, just to preempt some common questions, no there is no runaway process that is causing my CPUs to run hot (you can see the temp is quite reasonable).  Furthermore, in Ubuntu an Windows the fans spin down just like they should.

So, if anyone is running on this board or has some other suggestions, I would very much appreciate some help.

Thanks.

Re: ASRock Z68 Pro3 Gen3 - no fan control

Welcome to Arch Linux.  Can I get you to edit your post and wrap your output in BBCode code tags?  This link is the same as the one underneath the quick post text box.  It puts the output in a scrollable box and uses a monospaced font so the columns line up.

Thanks.

Re: ASRock Z68 Pro3 Gen3 - no fan control

Hi, I am having a board with the same chip, I think, and I am allso having fan issues with the curent kernel.

So far I have solved this by downgrading the kernel to 3.1.8 in which I can control the fan speed by

/sys/class/hwmon/hwmon2/device/pwm1

In kernel 3.2 I do not have a

/sys/class/hwmon/hwmon2

Re: ASRock Z68 Pro3 Gen3 - no fan control

Read a review of the Pro3 Gen3 that said the board itself only has low-speed high-speed, no flexible control.

I'm not sure if this applies to your situation, if it's normally fine-grain controllable from the OS.
