I can understand your decibel requirements but why a CFM and Static Pressure minimum? Are you using them for case fans and radiator fans?
( i'm just trying to explain why i made my choice, i'm NOT trying to convince you to change your choices / opinions. )
because i can use them for anything and everything, with uniform looks, for the same price as popular fans (like corsair) with double the db + double the rpm + half the airflow + no pressure rating. (when i say double or half, i'm exaggerating. ie 2000 rpm vs 3000-3500 rpm, 20db vs 29 or 39db, 90cfm vs 50cfm, 2.0 H2Omm^2 vs no rating. it's easier to say double / half then to geek out with specific percentages of comparisons) when i refer to the price, i know that ARGB fans can run 40$US, and that my choice of fans + ARGB fan frames means about the same price, BUT i can choose the fans with the specs i like, because function is 75% priority to me over the 25% priority in looks. looks are still important, and i still have "must avoids" when it comes to looks. Also, sometimes i can find great bulk prices, meaning i can buy more fans for lower costs, so i end up with extras that i can use in future upgrades or as spare parts. (ie, corsair released their 420 AIO after i bought their 360 AIO. the 420 AIO would be more uniform with all my 140mm case fans, and those fans i picked can be used as radiator fans if i change AIO in the future.)
like how many members here recommend Noctua fans (the bacon colored ones, sorry, couldn't resist the bacon reference!) the high CFM and static pressure minimums also mean that i can use PWM tech to run them slower, for quieter operation, and still get good airflow and pressure. I also like having mid to high pressure-rated fans so i don't have to worry about HDD drive cages or wiring (my wire management 20 years ago was non-existent) blocking airflow, as i still have older PCs in older cases that are not listed in my Signature.
i also know that most people find average corsair fans to be more than acceptable, and i'm happy they found something they like. i just prefer something else. i hope that's acceptable, too.
and i know that i am way more picky about my selections than most people. (i often wonder if i have a touch of OCD) however, knowing that about myself means i can make recommendations to others based on
their wants / needs, while ignoring my own required specs. in other words, i won't recommend what i want to others because i know i'm pickier than they are. partly because i end up spending more money (i don't want to recommend more expensive parts when they're not necessary for them), even though i don't need all the features. sometimes i have to bite the bullet, accepting / paying for features i don't need, because one feature i personally want / need is only available on products with all those extra features. for example, my motherboard supports LN2 cold booting, which i'll never use, but with all the 90 degree angled connectors on the front edge of the board, it looks freaking awesome in my case. my case is also expensive, but it has 3 compartments, main, side PSU /wire management, and bottom radiator / HDD cage compartment, and it has room for 3-420 rads + a 560 rad + 2 water pumps + looks great + is very durable. the vast majority of PC users are more than happy with $200 cases / motherboards, while i spent $900 on my case, and $700 on the motherboard. i wouldn't recommend either of them to the general consumer, and most enthusiasts won't even consider them. (i consider the tiers to start with general consumer, up to enthusiast (including hobby overclockers and entry-level competitive ones), up to world champion-ish hardcore competitive overclockers like K|NGP|N, up into the industrial / commercial tiers.) i consider myself to be an enthusiast, since i build my own PCs, but not a competitve overclocker.
TLDR: i'm picky, i know i'm picky. sometimes it's beneficial. sometimes it makes no sense. it doesn't affect my recommendations to others.
PS: please (i'm trying to be polite) don't try to convince me to stop being picky. and please don't imply that i'm wrong. you like what you like and that's fine, and i like what i like, and i won't try to convince you to change. i'm just trying to explain why i made my choice, i'm NOT trying to convince you to change your choices. your choices are yours. my choices are mine. i don't want to push my way of thinking on others. other peoples' choices and ways of thinking only help us give them better recommendations for what will make them happy, while sometimes offering alternatives to what makes us happy. if everybody had all the exact same preferences, etc... then there wouldn't be both Intel and AMD. there wouldn't be both Nvidia and ATI. heck, there wouldn't even be both i5s and i9s, or both ryzens and threadrippers.
PPS: some of my response comes from being berated / bullied on forums in the past 20 years, so please forgive me for being too defensive. or abrasive. i don't mean to be.
PPPS: thanks for letting me ramble. i know i sometimes talk too much, and i'm afraid of de-railing this announcement thread. if i wasn't so picky (and that's something i'm not sure i have a choice on) i would have seriously considered these fans for a build.
