No guys, you are wrong.
There is no such a thing as the cycle mode, the command
samsung-tools --cpu cycle
just set the next mode in a cyclic way (normal->silent, silent->speed, speed->normal). It's just a convenient function used by the Fn-F8 hotkey to select the next mode.
In all the three modes (silent, normal, speed) the cpu fan adjusts its speed automatically, the only thing that changes is the way the job is done.
In silent mode the cpu fan takes a longer time to increase its speed, in speed mode a shorter time. That's all.
For the standard behaviour, just set the fan to normal mode.
