Oh ok. So what was that about the noise level when set to pull in the previous posts above? Any idea?
Noise levels and sound signature are hard to measure unless you have the equipment and an experimental controls for them. My comment above was my experience with them pushing/pulling through a Corsair H100i in a Fractal Define R5. That said, it could be different for radiators of different thicknesses/FPI in different chassis, both in absolute amplitude and frequency spectra, depending on the aerodynamic impedance and vorticity character.
