I’ve gotten this ‘event code’ a couple of times now, it’s 0029, which is for a fan failure. It hasn’t actually failed, but I believe it’s in the process of failing. Currently, the diagnostic is showing as ‘healthy’, but as I said, I believe that the fan is failing intermittently and will eventually die.
The enclosure is out of warranty, of course, so I’ll need to replace the fan on my own. But where do I get a fan and which fan is best?
