WebOct 17, 2024 · The 'relaxed' fan curve is probably the wrong way to go about it. To ease up the revving, you're going to have to run higher minimum fan speeds. If the fan speeds are already 'up there', then the revving won't be as sharp. -Minimum fan speed of 60-70%, at a temp of the same number in C. -Middle fan speed of 80% at 80C. WebMar 10, 2024 · The aerodynamics of a fan can be charted in a fan curve, which displays the static pressure of the system dependent on the amount of air flow. As Turner noted, fan curves are read from right to left, …
