 I found out in meantime, that this has been caused by the added single Kingston RAM, with same features as required, which was also accepted, but it seems it is not 100% compatible, resulted in that faulty fan or sensor control… Very wierd…but that‘s the issue…
The first one went without issues, the second one is starting with higher fan noise, as soon as the OS, Windows Server 2022 Standard is starting. The hardware check showed the warning: "Systemboard Inlet Temp: Temperature Sensor LowNonCrit -> low." In the log I can find that it was reasserted afterwards... but no any impacts... All Firmware incl. iDRAC has been updated, though on the first server also with the older iDRAC FW worked without problems... What is the issue?
T350 Systemboard Inlet Temp: Temperature Sensor LowNonCrit - low
