Hello @Zlatko83 and welcome
your second picture shows the MSN number 20058395 of the PC case.
this is not the MSN number from the device itself.(look under the PC for the rihgt one)
the first picture shows the MSN number of the board MSN20063217 that belongs to one: ECS H110H4-EM2_DDR4 S1151 SPO V4
which has a BIOS OEM from Medion: 110M2W0X.2xx
maybe there is a more up-to-date bios than yours which can regulate the fan. (but don't give yourself too much hope)
please name your bios version, then we'll see.
another user may be able to tell you more about the fan control based on this data.
