They push 101m³/h air at a pressure of 1.008mmH²O
You AF140 pushes 115m³/h air at a pressure of 0.84mmH²O & 3 times the noise.
You'll be fine with these fans.
If you're looking for higher performance go with Phanteks or Noctua. They are a little bit louder than the BeQuiet but still quieter than the Corsairs while pushing more air and having more static pressure (and are usually around 5$ cheaper than the Silent Wings, you're paying for total silentness)
If temps were satisfying in your case so far and you want to go as quiet as possible, get the BeQuiets.
