[SOLVED] Error message from macfanctld on my iMac

Hello,

I installed macfanctld amd it is running now on my iMac. macfanctld -f shows me the following error messages:

Error: Can't open /sys/devices/platform/applesmc.768/fan1_min
Error: Can't open /sys/devices/platform/applesmc.768/fan1_manual
Error: Can't open /sys/devices/platform/applesmc.768/fan2_min
Error: Can't open /sys/devices/platform/applesmc.768/fan2_manual
Error: Can't open /sys/devices/platform/applesmc.768/fan1_min

Error: Can't open /sys/devices/platform/applesmc.768/fan2_min
Error: Can't open /sys/devices/platform/applesmc.768/fan2_manual

The command ps -ef |grep macfanctld shows me the following:
root 1111 1 0 06:24 ? 00:00:19 /usr/sbin/macfanctld

Does any one knows how to solve this issue?
