  1. Thanks @gprovost BTW apart this pwm fan issue, the helios4 NAS works great for me ! good job @gprovost
  2. after a bit more digging it seems that the kernel provided by armbian trough apt in version 4.14.14 does not enable PWM :-( root@helios4:/boot# cat config-4.14.14-mvebu | grep PWM # CONFIG_PWM is not set root@helios4:/boot# cat config-4.14.14-mvebu | grep LM75 # CONFIG_SENSORS_LM75 is not set the root issue seems here :-(
  3. Thanks for the hint, in fact I don't see any pwm1 available root@helios4:/sys/class/hwmon# ls -laR | grep pwm root@helios4:/sys/class/hwmon# I have only hwmon0 and hwmon1 # ls -l total 0 lrwxrwxrwx 1 root root 0 Feb 3 17:24 hwmon0 -> ../../devices/platform/soc/soc:internal-regs/f1072004.mdio/mdio_bus/f1072004.mdio-mii/f1072004.mdio-mii:00/hwmon/hwmon0 lrwxrwxrwx 1 root root 0 Feb 3 17:24 hwmon1 -> ../../devices/virtual/hwmon/hwmon1 if pwm1 is not present, is there a way to change the speed using the GPIO FAN ? Thanks for your help
  4. any potential temporary fix to reduce the speed of the FAN using CLI (while waiting for next build) ?
  5. using latest kernel provided trough "apt upgrade" # uname -a Linux helios4 4.14.14-mvebu #2 SMP Thu Jan 25 14:43:10 CET 2018 armv7l GNU/Linux the PWM/fancontrol does not work anymore. Feb 3 12:30:00 localhost fancontrol[5566]: Device path of hwmon2 has changed Feb 3 12:30:00 localhost fancontrol[5566]: Device path of hwmon3 has changed Feb 3 12:30:00 localhost fancontrol[5566]: Device path of hwmon4 has changed Feb 3 12:30:00 localhost fancontrol[5566]: Device name of hwmon2 has changed Feb 3 12:30:00 localhost fancontrol[5566]: Device name of hwmon3 has changed Feb 3 12:30:00 localhost fancontrol[5566]: Device name of hwmon4 has changed Feb 3 12:30:00 localhost fancontrol[5566]: Configuration appears to be outdated, please run pwmconfig again Feb 3 12:30:00 localhost systemd[1]: fancontrol.service: Main process exited, code=exited, status=1/FAILURE any idea how to fix it (the FAN at full speed are really noisy) ? (or how to revert back to previous kernel) Thanks
