![]() ![]() It also has a significant stall area within the medium airflow impedance region. The curve declines sharply, with the SP120 displaying mediocre airflow gains as the airflow impedance decreases. The Performance Edition of the SP120 has an outrageous maximum speed of 2300 RPM and our instruments recorded an outstanding static pressure of 3.42 mmH 2O at that speed. The performance of the SP120 is obviously much different than the AF120, as expected, but is also very different from the performance of the SP140 LED as well. ![]() The Quiet model has reduced fan speeds, which gives a very different graph: First up, the Performance model at 12V and 7V: The SP120 Performance and Quiet EditionĪs we move onto the Static Pressure line of fans, featuring fewer but wider fan blades (only 7 vs 11), the expectations lie in higher airflow in high-impedance (dense liquid cooler) scenarios. The performance of the AF120 fans is low when the impedance is very high but their volume flow capacity greatly increases when the airflow impedance falls below medium levels. While both AF120 fans in the graphs above share the same shape and design, with the only difference being their rotational speed, the performance curves are of similar shape but different magnitude. Whereas the quiet model has this response - note the axes are the same for both AF120 models in this case. This is the Performance variant pressure/volume response at 12V and 7V: Corsair's 120mm Performance The AF120 Performance and AF120 Quiet Editionįirst one up is the 'High Airflow' variant of the 120mm line (non-LED), which comes in Performance and Quiet modes.
