staking fans

[AMKKAM]

staking fan-with-fan, this is the configuration

will it work for cooling?

Do you mean stacking? No reason to stack fans over each other in a normal case.

I agree,

if you can just put two 200s in the front otherwise put 3 140s at the front or 3 120s

my bad, Yes stacking.
will it help increase pressure and airflow intensity?

Even if you had two 200mm back to back, they'd interfere with each other.

 

If anything it'll be worse with two 200mm & two 140mm, since much of the 200mm air would smack into the blades of the 140mm & rebound back & forth, impacting airflow.

Maybe? Some servers use stacked fans, but those are incredibly high pressure fans, all the exact same dimensions, and noise is not a concern in datacenters. This sounds like something that will cause more problems than... whatever you're trying to solve.

^^^ This, a 200mm is going to shove a bunch of air into the frame of the 140. It would be a very weird setup.

 

What are you trying to solve with this airflow configuration? There's likely a better way to go about it.
