(The photo of my fan is post removing some of the case, to see if I placed it in upside down) I had to take the extruder apart to get a highly rude piece of filament out, when I put it all back together the fan was very high pitched, and after shortly heating it up to 200 degrees to see if it worked, cooling it down, and heating it up again, there was a burning smell and it didn't read as going past 63 degrees I am uncertain as to if I plugged that power cable thing that goes into the back of the extruder in correctly, so that could have caused it. If that did cause it, is it likely that there is permanent damage?
