Not a big deal, but this is my first time dealing with something like this and it had me curious. The other day I noticed one of my Blue LED Yate Loons wasn't spinning but the LED was on. At first I figured it had kicked the bucket, but I cycled my fan controller for that fan to add more voltage and it spun right up. Of course after that, I could bring the controller right back to the lowest setting and it kept spinning. Finally the question: I've never had this issue before with the fan needing a little bit more starting voltage. Could this be normal wear and tear or a fluke?

The bushing or if it has a bearing is dirty.

That's what I was thinking. I'll wait until I see more issues before I pull her apart and clean/lubricate it.
