By top do you mean the roof of the case?
I used to have an H100 mounted to intake from the top. I know it doesn't make sense, and it goes against the natural path of air, but it gave me better temperatures.
The filters can be useful if you wish for your case to build up dust inside - it's easier to clean the filters than it is to clean the inside of your case + components.
However you do take a slight performance hit in terms of air flow being restricted.
Alternatively, maintain positive pressure to reduce dust build up.
Currently, I have filters on the fans on both of my radiators, it is so much easier cleaning the filters than removing fans and cleaning them + radiators.
