My hotend fan is failing.
-I thought it was the PSU fan, I submitted a support ticket 2200 on Friday week before last.
-Received a response Monday morning asking me to make sure it was the PSU fan
-I did more diagnostic
-Figured out it was the hotend fan, contacted support about it Wednesday last week and provided my address
-Replacement hotend fan was in the mail on the way to me by Friday, and is due to be here today.
I have heard horror stories about support, but mine was 10/10.
