Sure. In your great big world. In my tiny kitten universe, it only has 80mm fans that spin to a billion rpm.
Sorry, OP. Replacement fans for those gigantic Cor and Sair spinners could be: EK Vardar F3140ER, NB-eLoop B14-PS or Thermalright 147A SQ. The latter two will be quieter, but temps will be louder. And the NB-eLoop will sink your sunk costs faster and deeper.
Consider going big air or custom loop. The in-between solutions can soon become the most expensive.
