filter H100i if used an exhuast?

my setup:



storm scout 2 case



2 noctuas pulling air in the front (have a semi filter grill)

1 side fan that only comes on when the system hits a certain temp (just installed a thermaltake magnetic filter)

1 rear exhuast fan

h100i rad mounted on top (externally), 2 noctuas mounted internally pushing air out (exhaust)



now i know there are 100 recommendations on the best setup, but this is what i have choose for now.



i was installing my hx850i yesterday and did a quick clean, i noticed my rad had a good amount of dust hidden in it.



would it be beneficial to place filters on my noctuas that blow up and out through my rad?



if so, are they any recommendations for a good filter that can be easily removed and cleaned?



thank you,

Carlos
