Dear Community,

I purchased a NanoPi M4V1 4 GB with NVMe Hat, NVMe SSD and metal case with 12V 0.12A fan. Besides the SSD all products are originated from friendly ELEC, which are sold from their web store. armbian is successfully installed on NVMe SSD with boot from SDHC card. For powering the NanoPi M4, I am using a 5V 4A Mangoo power plug. The problem, I discovered, is that the fan for cooling the metal case does not spin, when the NanoPi M4 is in operational mode.

Please could you tell possible causes for this issue?

with best regards JGDE
