I have 2 front fans that are pushing air inside the case and i also i have 1 back fan that is also pushing air inside the case. Should i rotate the back fan so it pushes air outside the case? Because the back fan does not have a dust filter and its pushing dust inside the case. Dust is trouble because it will scratch my size panel window and it will make the PC components dirty.

Correct me if im wrong but if the fan logo is showing it means that its pushing inside the case?
