Looking for high Static pressure low noise rad fans

Like any good enthusiast I let my GTX 1080 Ti SC2 HYBRID work as it was originally intended. Now I have the optimization itch as the fan that it comes with on the rad does not seem to push that much air out of the case, keeping the rad temps around 52 C in this current weather.

My question, what are some good high static fans (typically used on rads) that are quiet to quiet-ish and won't break the bank either.


I run those on my rad. Fine there quiet and good airflow.

No first hand experience, but I read good things about antec sp fans.
