Sometimes they don’t even get a chance and are immediately replaced by other, “better” ones. We’re talking about fans that come pre-installed in computer cases. We are going to test one of them now and although there are reasons to replace the Dynamic X2 GP-12 (PWM), be careful not to end up being worse off. After all, these aren’t exactly ordinary fans. They even have more specific aerodynamics and acoustics modifying features.

I’m wondering how reviewed fans relate to 140mm version, Dynamic X2 GP-14.
I have three of them mounted as stock fans in Fractal Design Meshify 2 case and 3x Fluctus 120 PWM in drawer.
GP-12 are clearly inferior to Fluctus, but what about 140mm GP-14 vs 120mm Fluctus when used as 2x intake and 1x exhaust case fan?
Sooner or later we will get to such a comment. Anyway, these are structurally completely different designs, where the Fluctus 120 PWM is handicapped by higher tonal peaks at lower frequencies and with the Dynamic X2 GP-14 it might be again (like the Dynamic X2 GP-12 PWM) a relatively noisier, gently whirring motor. We’ll see…
