Pc air pressure

[g0ated]

Is it okay to have more exhaust fans than intake fans, I have kept in mind that I would have to clean more often but will having more exhaust fans affect the pc components?

Not sure what you mean by "affect components". 

 

It won't affect anything besides dust buildup and temperatures. 

 

Whether what you want to do is good idea or not depends on many factors. 

 

Some cases benefit from negative pressure, others don't. Fan RPM matters as well, you can still have slow spinning exhausts and fewer fast spinning intakes and achieve positive pressure, etc...

@WereCat will the Corsair 7000x pc case benefit from negative air pressure?

Looks like a typical front to back airflow case with positive pressure in mind. 

 

Do you plan to water cool?

Yes I plan to use a 360mm water cooler

Why is that though?

I'm assuming you want to top mount the radiator and use the 3 fans on the radiator as an exhaust while keeping the one fan in the rear as exhaust as well.

 

In which case the radiator will block some of the airflow and also assuming that all fans are the same or very similar then it should still result in a mostly positive pressure depending on the RPM of the intake fans.

 

Anyways, this shouldn't cause you any issues if I'm correct about my assumptions.

Thanks for the explanation

 

also one more thing will a push pull aio orientation be better for my case(not pc case lol)

Push pull is not really worth it. The temp difference is very small on AIO while you will introduce way more hassle to cable management, cleaning, mounting and potentially also increase noise just by having more fans... also costs way more for what it's worth.

Ok thanks thats all I needed to know. I am going to be building my now
