The fan in the FX350-G is a 40x40x15mm Jamicon KF0415B1HR-R. 12V, 0.17A. Doesn't seem to be PWM-controlled. Judging from this catalogue it has air flow of 8.84 CFM (~15m³/h) and static pressure of 0.237 inchH2O (~6 mmH2O). I was going to change the fan until I realized it's 15mm. I guess any Noctua A4x10 will fit but those only move ~9m³/h with pressure ~2 mmH20.
