Bolt 4K Fan Curve (Non Venice)

When recording is not detected the fans will turn on at 35 °C and ramp-up to full speed at 60 °C.

When a recording flag is detected the thresholds are changed so that the fan does not turn on until it reaches 66 °C and will ramp-up to full speed once you reach 76 °C.

These values are for the internal temperature displayed on the OLED rather than the chassis or ambient temperature.
