fan_level=1 RPM differ depending on system state - works correctly after waking up from sleep. #133

Hi,

thanks for nice app, really useful. I have one problem with varying fan speed.

After reboot and systemctl stop thinkfan, then sudo thinkfan -n fan works at ~2000 RPM and fan_level=1. It's the same if I don't stop it, when it runs in the background.

:/proc/acpi/ibm$ cat fan
status:     enabled
speed:      2067
level:      1
(...)

After going into and waking up from sleep sudo thinkfan -n runs it at ~1600 RPM and also shows fan_level=1

:/proc/acpi/ibm$ cat fan
status:     enabled
speed:      1608
level:      1
(...)

1600 RPM is correct - it runs like that on Windows after installing all Lenovo drivers. I have TP T540p.

My /etc/thinkfan.conf:

hwmon /sys/devices/platform/coretemp.0/hwmon/hwmon4/temp3_input
hwmon /sys/devices/platform/coretemp.0/hwmon/hwmon4/temp4_input
hwmon /sys/devices/platform/coretemp.0/hwmon/hwmon4/temp1_input
hwmon /sys/devices/platform/coretemp.0/hwmon/hwmon4/temp5_input
hwmon /sys/devices/platform/coretemp.0/hwmon/hwmon4/temp2_input

(0, 0,  40)
(1, 35, 60)
(2, 50, 61)
(3, 52, 63)
(4, 56, 65)
(5, 59, 66)
(7, 63, 79)
(127,   75, 32767)

What can I do to make it run 1600RPM on level 1 after restart, without going into sleep?
