RED DSMC OPERATION GUIDE

955-0020_V5.1, REV-H | 76

FAN AND TEMPERATURE MANAGEMENT

Each RED DSMC is controlled by complex thermal algorithms to ensure that both the sensor and camera op-

erate at a safe temperature. Each fan control mode affects the sensor temperature, sensor warm-up time, fan

speed, and resulting fan noise.

When selecting a fan mode, RED recommends that you take into consideration how each fan mode behaves,

and then select a fan mode that fits the needs of your project.

Regardless of your sensor type and target temperature, 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 for your bottom fan. If a top fan is installed, it will activate at a constant speed when

necessary.

NOTE: If you select a new fan setting, run the DSMC until the core temperature stabilizes, and then perform a

black shading calibration.

NOTE: If you’re using a top fan, the top fan may not run immediately after turning on the DSMC, as the top fan

runs when the DSMC requires additional cooling power.

NOTE: Manual and Auto modes require that you actively manage the sensor temperature, because these modes

focus on controlling fan speed and do not target a narrow sensor temperature range. The T/E status icons can

be used as guides for proper temperature calibration.

ADAPTIVE

Select a target temperature and the bottom fan self-adjusts to maintain the selected temperature. The default

target temperature is 65°C. This is the default mode for EPIC DRAGON and SCARLET-X DRAGON.

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.

 EPIC DRAGON and SCARLET-X DRAGON: Target temperature range is 55°C to 70°C. A target temperature of

65°C works best across most environmental conditions.

 EPIC MYSTERIUM-X and SCARLET MYSTERIUM-X: Target temperature range is 45°C to 70°C. Target tempera-

tures above 50°C will give noticeable fan noise improvements when compared to Auto mode.
