WebIn my bios fan control settings there are four dots on the graph and a graph for each fan. I've set all of the fan graphs up as follows: (point 1) 0 degrees celcius = 50% speed; (point 2) 60 degrees celcius = 50% speed. These two values ensure that the fan runs at 50% the majority of the time - namely when the CPU temperature is anywhere ... WebApr 1, 2024 · Fan Performance Curve. The first point on our graph is the duty point: 12,000 cfm (5.66 m³/s) at 5-in.-w.g. (1,244 Pa) static pressure. Adding data showing fan flow and pressure at points other than the duty point produces the first curve, shown in black in Figure 3. FIGURE 3: A flow-versus-pressure curve.
