Will a higher static pressure make a difference? Noctua

[AMD Lover]

So I was looking this this NF-B9 redux-1600 PWM compared to this NF-A9 PWM. The Redux will better match my build but the static pressure of the redux is 1.61mm compared to the NF-A which is 2.28mm. This seems like a large difference and the fan will be pulling through a CPU cooler and a side panel the CPU cooler is pushed mm away from.

 

Is the static pressure going to make a difference? Couple degrees?

 

 

Thanks!!!

The difference is mainly due to higher rpm but the NF-A9 is just a better fan across the board. If you don't mind the extra cost, it's hard to go wrong with. 

Specs?

It depends how fast you want the fan to spin.  If you max it out at 1600rpm it will sound like a Jet.  So you reduce that greatly so its silent and what not.  Also no it wont make a real world difference in temps what will make a difference in temps is simply the fan speed and what not.

No, no, no, please no.  Don't comment on things you have subzero understanding of.  1600rpm is basically silent on the B9 redux, because it basically doesn't move any air

The nf-B9 redux is, absolutely not the fan for this use case.  The flat, high angle blades and low rpm make aesthetically pleasing and quiet fan an atrocious option for any usecase with a level of restriction.  If the nf-a9's colors are a big stopping block, I recomend either of these guys as an excellent stand-in of equal quality.  Noiseblocker isn't as well known as noctua or Be quiet!, but it stands toe to toe with any fan on the market.

I was referring to his fans.  If he has Radiator then yes it will help.  Sorry for not mention that.  I was just thinking as a regular fan front intake or rear exhaust you dont need it but if its going on a Radiator then pressure fans will help reduce your temps.

Did you read the OP?  Clearly states that it's going to pull through a radiator (the cpu cooler) and a side panel

I actually remember those fans from back when frozencpu.com was the shit 

 

Just looked up spec sheet and the 92mm EB has horrible SP (0.872 mm)

Yup, I'm not sure why it's so atrocious on the spec sheet.  In past tests where I pitted the a9, b9 and NB PE-P against my 92mm gentle typhoon out of curiosity the redux was pasted while the a9 and PE-P had a closer margin.  Unfortunately I didn't keep any data logs as I was in a rush at the time

 

Edit:

Oh, I still have the B9, now that I think about it.  I could do some testing vs my gentle typhoons and an a9x14 on an L9i if ya want

 

Edit 2:

The A9 was an easy number 2 on the list, not a strong as the typhoons performance wise but slightly quieter.  Definitely beat the competition you can actually buy

It's been tested plenty of times. The NF-B9 performs worse on the NH-L9i than the stock fan. It's not meant to be used on such a dense heatsink.

What method did you previously use for testing?

I was tossing them on my u9xdi4 actually, I just don't have it any more, thus the offer to test on an l9i
