then buy whatever fans you want but you just said you dont know what your doing essentially so.... you can either take the best fans available or buy something else your choice. good advice is good advice when followed, you dont have to follow it but if you buy something thats not up to snuff and you end up worse off you'll have some more junk fans that dont suit your needs.
that said
could go with solid black Delta's their loud and semi obnoxious but cooling performance is top notch,
could go with Corsair High Static Pressure fans and add in the Blue rubber ring or w.e it to customize the appearance to what you want,

but in the end the Gentle Typhoons are still the best fan in the lineup overall in terms of noise to cfm to static pressure and are cheaper than the corsairs
There are higher speed Gentle Typhoons as well but a fan controller would be a good idea using those as they are 3000-5400 RPM variants.
GT AP-15 12,99 €*

Corsair High Static Pressure 13,99 €*

if your trying to keep a blue black color scheme why have Memory with grey heatsinks ? lulz the GT-AP15s would at least match those and offer a complimentary color match to said components. corsair fans you can change the outer rim color but as far as BLUE fans with good specs good luck most are shit LED fans
It also goes without saying that MANY fans are OVERRATED aka the specs stated by the manufacturer are far far shy of what they specifiy, a good example of this would be my old coolermaster R4 fans they were supposedly 90 CFM etc they pushed less air then my cheapo yateloons mediums which at low speed via fan controller still push more air. So while the GT-APs are on target and im going to guess the Corsairs are as well many cheaper fans of various makes and models are just plain crap.
