Fans, Fans Everywhere

Hi all!

 

So as the title suggests I have a lot of fans on my mind and I was wondering if you guys could help fill me in on what your personal experiences with fan types/brands are and what the ultimate performance has came down to.

 

What I want to know is what is the overall most silent/well performing fan?

I have a Fractal silent series R2 120mm and I can definitely hear it, yet it's rated at 15dB!

And before everyone says "NOCTUA"! I need to point out that iI haven't found a Noctua that is listed as lower than 15dB. I guess the could be quieter on a dB to RPM ration but what I want is the CFM to dB ratio on all fans.

 

Also I want peoples performances with the Corsair h80(i)/h100(i) with all types of fans, and for this i'd be wanting to find the best Static pressure to dB ratio.

 

Thanks for reading and I hope to find some answers down below :)

Akasa Viper 140mm - 3.12mmH2O @ 26db - 110 cfm

these work better and are quieter than any noctua 140mm fan (YMMV). its just a fact (not really a fact per-se but thats my experience).  I own Akasa Vipers fo rmy rad fans, and I have owned Noctua's as well.  Noctuas are great for running silent at low rpm, but then you get very low static pressure and low cfm.
