Thanks for the replies! And yes, the cracks do appear on the other fins in the lower layer as well, all on the same side which is nearest to the only fan attached to the tower.

Hello! I couldn't find anything similar anywhere so decided to start an account and seek help here instead. These "cracks" appeared on my hyper tx3 after using it for approx. 2 years. Confirmed that this isn't dust particles as they do not disappear after wiping it down with a rag. Is there anyone that could tell me whats happening here? Also, while this is still looks pretty small, is there any concerns for the near future which I need to take care of?
