X-controller Fan loud - Not the usual

The x-controller fan on my early model x-carve which has been upgraded was getting louder, and yes, I’ve heard the bit that once you’re carving you can’t hear it, which is true but when you aren’t it was super annoying (I guess I should do more carving). I finally got inspired to switch the fan out on the back, and to my suprise the fan was just fine but somehow had some chips of stuff sucked into the fan shroud acting like a baseball card in the spokes! Once the air-blast had knocked them out it ran fast and quiet (I mean it’s not ultra-quiet Noctua but pretty quiet for what it’s been the last few months. So before you go getting replacement 24V 40mm fans just check that noting is in the fan.
