A lot of fans from linear cracks.

With which shapes should these traces be identified? A lot of fans?

I would use the fan tool. If it looks linear and you can sort of tell a direction mark it with the fan tool. In this case you can tell one side is darker than the other, so the darker part is where the dirt and dust are originating from and the lighter areas are where it going to so I would say the fans start on the right and move to the left.
