You can use the utility to read the diagnostic files. You have "edit" the base station and then the "diagnostics" become available on the utility main menu. It's not too hard to make sense of the logs. They are listed in reverse chronological order.
I know this is old but someone else might have the same question. I don't know if the express is different. I have both on my network and I can only get diagnostics for the base station.
When removing the fan pay attention to the cable. It is glued down with sticky tape and is routed beneath the rubber seal that mates against the case. You may want to remove the power supply cover first since the cable for the fan is routed beneath its cover. But once the power supply fasteners are removed the power supply is dangling from its cables so be careful to relieve the strain.
