I7-6700k oc'd to 4.65
Corsair h110igtx
Corsair 400c tower

Have it set up in push pull; ml140pro fans in push, blue ml140pro's in pull, my big question here is, I have four sp140l's laying around, would I see a difference if I set them up on the radiator, or would the ml's be the same?
Again, these are sp140L not standard sp140s

Present temperature:
Idle temps: 13-15c
load: 45-50c (bf1 on ultra)

Is there a difference? Yes.

SP140L, at full speed (2100 RPM), puts out 119 CFM, 3.99 mmH2O and 43 dB(A).
ML140 Pro, at full speed (2000 RPM), puts out 97 CFM, 3.0 mmH2O and 37 dB(A).

With SP140L, you can get a (little bit) better cooling performance in expense of noise.
