FAN AND TEMPERATURE MANAGEMENT
The camera is controlled by complex thermal algorithms to ensure that the sensor and camera operate at safe
temperatures. Each fan control mode affects the sensor temperature, sensor warm-up time, fan speed, and
resulting fan noise.
When selecting a fan mode, first take into consideration how each fan mode behaves, and then select a fan
mode that fits the needs of your project.
Regardless of sensor type and fan mode, you will get the best image quality by performing a black shading
calibration at the temperature you want to use for your shoot.
FAN CONTROL MODES
Select a fan control mode.
NOTE:
After selecting a new fan setting, run the camera until the core temperature stabilizes, and then perform
a black shading calibration.
NOTE:
Manual mode requires that you actively manage the sensor temperature, because this mode focuses on
controlling fan speed and does not target a narrow sensor temperature range. Use the T/E status indicators as
guides for proper temperature calibration.
NOTE:
Maximum speeds are intended as target speeds only; actual fan speeds may be higher at times due to
long recording times or high ambient temperatures.
ADAPTIVE (TARGET TEMPERATURE)
Adaptive is the default mode for WEAPON/SCARLET-W.
Select a Target Temperature and the fans self-adjust to maintain the selected temperature. The default Target
Temperature is 39°C. After the camera reaches the Target Temperature, and if the ambient temperature remains
constant, Adaptive mode results in a consistent fan speed and fan noise over time.
Targeting a higher temperature raises the sensor temperature, lengthens the sensor warm-up time, and lowers
the fan speed. Targeting a lower temperature lowers the sensor temperature, shortens the sensor warm-up
time, and increases the fan speed.
NOTE
: The intent of Target Temperature is to set the sensor temperature so that you can then create a calibration
map for that temperature.
NOTE
: When the camera turns on, the Target Temperature is the temperature of the current calibration map,
regardless of what the Target Temperature was before you turned off the camera. Setting a calibration map also
overrides the Target Temperature. For more information, go to
