1 or 2 top exhaust fans?

[bubbz1324]

I cant find an answer anywhere for this. Obviously it would benefit having 2 fans over 1. But is the 2nd one necessary? I have the corsair 500r and i want change the stock fans for better fans that have red LEDs. The way i want to lay it out right now is as follows...

Front: 2x Cougar dual-x Red 120mm intake
Bottom: Corsair white LED stock intake
Side: Removing 200mm fan and modding a window
Rear: stock 500r exhaust
Top: Unsure?

Im thinking of putting 2 corsair AF 120 LEDs but i could save money and just get one 140mm. Suggestions?

get one 140mm instead of two 120mm because the 140 will be less noisy and good airflow

ok, and how should i go about covering the other fan hole? theres no dust filter there. i dont want dust to get in through the other one

you suppose to have a shroud on the top (black cover )

i know i do, but the mesh is very porous and dust would easily get through.

ok do not panic about dust...you will always have dust inside the case even with a mini bug screen
thats normal , thats why we do a cleanup with a duster can
