NZXT H440 front intakes 2x 140mm vs 3x120mm

[Kameegaming]

So I am currently installing fans, and I just realized this motherfucker can't fit the 3 140 mm noctuas I have only two.

Should I return these and get 3 120 mm noctuas instead or just install 2 140 mm fans?

140 mils run quieter dou

[ThinkWithPortals]

They should shift similar amounts of air, and the 140s will be quieter. I always suggest having less large fans than more smaller ones

For max Air I am running triple 120mm intake in my h440...

 

But alot of people want the more "efficient" 140mm fans. But for positive pressure and not that much of a difference in sound I would go with 120's

Well the 2x 140mm fans would give you 280mm² of airflow surface area, while 3x 120mm fans would give you 360mm². You could run the 120mm fans slower than the 140mm and still get more cooling (to a point), but I don't think it's really worth going through the hassle of returning fans, especially since 2x 140mm fans would still move a lot of air.

3x120mm will move more air, 2x140mm will be quieter. Knowing the reputation of shabby airflow of the H440 I'd much rather get whatever airflow I can.

 

EDIT: The difference wouldn't be anything world-changing but just my personal preference.

The difference in airflow is 156 CFM for the 140s vs 165 CFM for the 120s

mm/H2O difference is:

140mm:

2*1,91 = 3.82

 

120mm:

3*2.61 = 7.83 or 3*1.83 = 5.49 with Low Noise Adapter

I would like to have positive pressure for the case since I will move to a dusty environment.

Exhaust fan is a Corsair AF 140 Quiet Edition:

67 CFM - 0.86 mm/H2O

and 2 SP 120 High Performance PWM's on a H100i GTX as top exhaust.

62 CFM - 3.1 mm/H2O

Its completly up to the fans you use dude...

these are the actual numbers for the Noctua fans

Well its all right and stuff.... But what fans are they (this kind of info kind of helps if you are going to go through with calculations)

Your a moron you can't just add the diameters fan then square it to work out the area there circles

Here's a little rhyme to help you out

Round the circle pie time d

When it area we declare we must use pie r squared

Half the diameter square it times by pie then multiply by two

Yikes! 

 

You could've just told me I was wrong. I now realize I was wrong, but I guess I just didn't want to do math at the time. Sorry.

Well , the picture speaks for itself 

 

10 points to how can guess wat is the one in the middle ... also planning to do the whole front with that one , but it isnt cheap .

Cooler master Silencio? those are pretty cheap here.
