[HaZe002]

i want to buy a Cooler Master Masterbox mb520 RGB, but i want 2 extra fans. Cooler Master have a picture on their site where exhaust is the two on top pluss the one in the back as exhaust, 3 fans at inlet in front. BUT there is a dust filter on top, aswell as in front. what fan directions is the best?

follow nature, The rule of thumb on any case is bottom, front, and side should be intakes rear and top should be exhaust.


Sometimes you might need to deviate from this a little but 99% of the time thats how you want your fans set up.

The dust filter isn't for when the pc is on and running, the fans exhaust will blow any dust away from that area. The filter is for when the pc is Off, it helps prevent falling dust from entering the pc from the top vent.

Generally.

There are some ppl who only use a rear exhaust fan, no top exhaust. In that scenario a dust filter is an advantage. The cpu/rear fans produce low pressure areas directly in front of the fans, they'll suck air from the nearest available source, the top. Air isn't heavy, but is susceptible to air pressure and thats 14.7lbs/in² pushing down. That pressure can overcome the rising air from the front intakes, providing an airflow from the top into the cpu fan/rear exhaust.

So if you run stock case fans alone, no top exhaust, a top dust filter makes much sense. Has very little affect on top exhaust fans, sp is too high.

Thanks so much!
