Your understanding of dust filters is a little bit incorrect. Dust filters in a negative air pressure block only the entrances where fans are taking in air. However, if there is no filtration wherever the case has air coming in, there will be dust.
In a positive pressure case, air is trying to escape so the only place where air is entering are where your fans are sucking in air.
Ina a negative, more air is being exhausted meaning all potential inlets for air become potential for dust. The antec 900 is a clear example of a negative pressure air case that is a dust MAGNET.
The fan on top is large and so is the psu, so two 120mm intakes are dwafed by the top, rear, and psu/GPU exhaust meaning dust is accumulates faster.
It's not a big deal, it just saves me ten minutes every now and then and it's something I don't have to be that think about as much. Also knowing I did it the way I planned to is part of why it's valuable.
I recommend try using the side fan as intake since not much hot air is not going to be exhausted from that area. Try both. See what your temps are. I'm guessing intake...
