I'm fine with dust as long the performance overall is better, thank you all for the advice.

So I did a stress test and the results with the slot covered peaked at 65º versus the slot open peaking at 68º. Guess I will keep it close and top fans exhausting, thank you.

Thank you, I'll keep the top two as exhaust then. The case is a Nox Coolbay VX, it only supports two 120mm fans at the front. By the way, should I cover that second top fan slot in the side panel, or keep it as is to bring cool air in (despite being summer..) ? Due to the cooler, I cannot place one fan there.

So the last couple of days I've been wondering what to do with my two 120mm fans on top of my case. Even with similar case structure, some people set the fan as an exhaust rather than intake, even thought there are filters on top of the fans, so I guess that means it's intake ? I made a sketch of my case and build, if it helps.. Also, I forgot to mention the lateral case fan is serving as a intake, but it as no filter, should that mean it's an exhaust too ?
