Do I want more, less or equal input to output fans?

[NickW93]

Hello, I've just made my first build and am debating whether or not to get a few extra fans for it. I'm not sure if its best to have more input fans or more output fans. I believe my case has room for two more 120mm fans in the front and if it will keep my computer a little more cool I'm all for it.

There are many threads of thought for this problem, whether to use a high or low pressure setup. This article was very useful to me when i setup my system.

More intake results in positive air pressure in the case. Positive air pressure will result in passive ventilation. More exhaust fans result in negative air pressure in the case and enable passive intake into the case.

Thanks for the articles and tips. I think I'll just stick with the three fans that the case comes with and see how that works out for me then. If it isn't working I'll add an extra intake.
