Stock vs Corsair fan positioning

[ernie mills]

Hi, I was hoping to get a piece of advice for my airflow layout. I have an NZXT H510 case which comes with two exhaust coolers (top, rear). I also purchased two corsair ML120 fans for intake (I know this case is designed for negative pressure but I didn't want dust getting sucked in from every orifice). Given that this case prioritizes negative pressure, should I use my nicer fans as exhaust and use the stock as intake? Essentially keeping the positioning the same for all the fans just switching the exhausts with the intakes. Or does this not matter at all?

 

Thank you!

I personally would use the two ML fans as intake (good choice), and use the one stock fan as exhaust, this will ensure positive airflow.

I understand wanting to achieve positive airflow I was just wondering if it makes any difference using the nicer fans as exhaust vs intake since there will be 2 in and 2 out no matter what.

I don't think so. The ML fans are probably better optimized for static pressure than the stock fans, meaning they are better for intake fans so they can fight the front panel for airflow, doing a better job than the stock fans. Makes more sense in that config.

Great, thanks for your replies!

No problem!

 

Watch this LTT video on airflow, it is one of my favorite!

I would use the ML ans intake and stock fans as exhaust.

The ML fans are overall a much better fan with more performance than the included Aer F120 fans.

ML120 have a much bigger rpm range 400-2400rpm with higher flow and pressure.

Compared to Aer F120 500-1500rpm. 

And the ML are more quite (unless you crank them to 2400rpm )

Try it out and see. It's hard to tell how the system would actually perform due to how complicated airflow can be with the unique obstructions involved.
