I recently installed Vmware Esxi 6.7 u3b to a hp Microserver Gen10 plus and taking a look into the Hardware Monitor I can see the status green except for the fan in red.
I tried to install Vmware Esxi 6.7 custom Iso for HP gen9 and forward but the monitor showed the same allert.
I checked the hp bios health status and everything seems to be ok. When I reboot the machine I can hear the fan moving.
Are you aware if there is any common bug?
Thanks and regards.
