Static Pressure or No? Arctic BioniX P120 or F120 for Fractal Node 804

[Pcexbird]

I'm buying cooling fans for my Fractal Design Node 804 today. I've decided on the BioniX line from Arctic.

 

I cannot decide if the static pressure optimized version (P) is better suited for my Node 804 or their case fan variant (F)? Both offer similar CFM (high 60's) The pressure optimized has a 2.62 rating and the case fan variant doesn't publish static pressure measurements.

 

For those who are familiar with the Fractal Node 804, it does have a (very) restrictive front panel and grille slits cut in the top fan positions as well (and 3 filters total). I'm buying 8 fans so I want to be certain. 4 front intake 1 top intake and 1 top exhaust and two rear exhausts. Should they all be pressure optimized versions or mix of the two versions?

 

I am trying to keep the fans all the same for PWM and temperature tuning reasons. This is a split chamber design computer case.

 

Pic one is the pressure optimized BioniX. (With less blades)

 

At bottom is their non-pressure optimized version. (More blades, thinner blades)

F-series for case fans, P-seires for heatsinks and radiators.

 

The new Arctic P-series fans are meant for heatsinks and radiators which need all that static pressure to enable air to flow through tight angles.

What would be the disadvantage of running the higher pressure fan? I did notice on their site they said a qualifier was tight mesh for the P series? Would you go with the case one even knowing the mesh and filters,etc?

My suggestion now that I look at pictures of the Node is to go ahead and get the P-series fans, since the case is compact that the static pressure would direct airflow nicely. If you're going to be using mesh/filters, the static pressure assists in getting air pushed through a lot.

 

I'm not an aerodynamics expert despite my love for air cooling, I'm talking from my own personal experience with my own case fans, since I actually do use static pressure case fans in my NZXT S340 since the case space is super restrictive especially at the front where it's blocked off and also has a dust filter in addition.

Thanks for your help bud! Ordered 6 to start with...should get this baby moving along ...
