Case Fan Advice

[Griffinix]

So I have just finished my build and would also like to replace all the fans on my Cooler Master Stryker. I have already got three Arctic Bionix F140 fans as exhausts in the top and rear of the case. What I am wondering is if I should get three or four Arctic Bionix F120 fans as intakes or go for more pressure orientated fans for the intakes like the P120. There is literally no consensus on what kind of fans should be used on filtered intakes (some say pressure while others say high airflow).

Only the bottom hard-drive cage has drives in it and they are all SSD's and thus have a small footprint. So would I be fine with the fans mentioned or would more of a hybrid fan be better suited for my needs?

Static pressure fans are more for radiators and filters. I would go with high air flow.

Static Pressure is there to overcome restrictions. Doesn't matter how high your airflow is, if it can't get through the filter.
However, you want to make sure you have the highest possible Static Pressure rating, AND the highest possible airflow with it.

The problem is that those that are good at both have a tendancy to sound like a jet ready for takeoff.

The problem is in the combination of whichever fans, and whatever the airflow has to go through.
For example, rads with high FPI combined with close fit fans that have a wide airflow projection, resulting in compression and loads of air bouncing around, with the end product being a flippin' loud air flow!

Unfortunately, without some seriously detailed research and calculation, the best way to figure out these things is just to try some in your individual case.
But basic rule of thumb, the higher the SP rating, the more air will make it through a restriction. The higher the airflow, the more air volume it has available to push through in the first place. High SP and AF values on the one fan are becoming more common, but even today it easily comes down to an SP:AF ratio to find the best.... and that's without factoring in the variables above, or the actual noise ratings.

Exactly what my thoughts have been on the matter based on research. The F120 have very good airflow but their static pressure is not the greatest. The P120 still has decent airflow, infact not much worse but the static pressure is higher. Arctic's support told me i'd be better off with the F120 because airflow is better for case intake and exhaust in general.

The only hybrid fans I can see that seem to fit the bill are the likes of Corsair ML, Cougar Vortex or other relatively expensive fans. While I would like to have some led on the front of my case it is not essential.

edit:

Come across the Aerocool Dead Silence 120mm fan. Looks promising as it has really good airflow with decent static pressure and a white led and should look good in the front of my case. What do you guys think?

Only if your intakes and exhausts have no restrictions, like grilles, meshes, filters, etc...

Well yeah, performance costs... EK Vardar 120ER fans are pretty good too, as can be Gentle Typhoons, but again it all depends what's in the case you're putting them up against.
