loud af

Hi there, I need 3 120mm and 3 140mm fans for my watercooled build. I currently have 1 corsair ml 120s as exhaust and 2 on the top radiator and 3 140s on the front radiator. when the cpu is under load it is just too loud. I hover at 67-70.c gaming at this volume any less rpm and it gets to 80+...
