This happens to me on the old hardware too, try to power cycle the enclosure.

no TWSI errors, which i get all the time on my older unit. cycling the power did not help either,,

so this is not common to the newer units then, just a problem with this particular one?

yes, and using fanspeed w 2000 for example, will do nothing. the speed remains the same, and fanspeed g always reads 0.

I've modified the ctrl_fanspeed.sh script to work with the new fan.

It basically stops the fan below 108.  (Because stopping the fan shuts down the box, i've set it to low for now, until I can figure out a way to fix this).

Sets the fan at low above or equal to 108.

Sets the fan to high above 140.



#!/bin/sh
#
# This script was created at http://dns323.kood.org by FIB,
# it has been slightly modified by leper (with help from
# fonz). It sets the fanspeed of the device depending on
# the temperature, which is measured in Fahrenheit. If
# your box measures temperature in Celsius, you need to
# edit it to work.
# Additional changes by gartylad.

# Set the path to use RAM-disk instead of harddrive, to
# execute from. This is done so that the disks will go
# into sleep mode, while the script is running.
PATH=/usr/bin:/bin:/usr/sbin:/sbin

Create a logfile on the RAM-disk.
LOGDIR=/log
FANLOGFILE=${LOGDIR}/fan_ctrl.log
mkdir -p ${LOGDIR}

# Kill the old fan controller.
kill -9 `pidof fancontrol`
#echo "Fancontrol killed. Installing fan_ctrl.sh" >${FANLOGFILE}

# With temps between T1 and T2, the script automatically
# lowers/raises the fanspeed between RPM1 and RPM2. This
# it does every update_interval seconds.
update_interval=120
T1=108
T2=140
RPM1=2300
RPM2=4500

while [ 1 ]
do
  T=`temperature g 0`
  T=${T##*=}
  # Check if temperature has fallen below T1 value
  if [ $T -lt $T1 ]; then
    # Temp below T1 fan stops
#    fanspeed s    # stopping the fan causes the machine to shutdown
    fanspeed l
    echo `date`"::Fanspeed stop" >>${FANLOGFILE}
  elif [$T -gt $T2 ]; then
    # Temp above T2 start fan at high speed
    echo `date`"::Fanspeed high" >>${FANLOGFILE}
    fanspeed h
  elif [$T -ge $T1 ]; then
    # Temp equal or above T1 start fan at low speed
    echo `date`"::Fanspeed low" >>${FANLOGFILE}
    fanspeed l
  fi
  # echo `date`" ::CURRENT::" $T"F" ${CONVFTOC}"C -- fanspeed:" $newRPM "(written to "${FANLOGFILE}")." >>${FANLOGFILE}
  # wait for next cycle
  sleep $update_interval
done
