Auto mode:
Chassis fan speeds reference GPU temperatures and operate based on the default factory setting.
Manual mode:
Allows you to set a fixed speed for connected fans.
User-defined mode:
Allows you to set chassis fans to reference either the CPU or GPU temperature to determine rotational speed. Additionally, a smart, automatic calibration routine senses the controllable range of connected fans and allows you to fine-tune speeds for efficient cooling and low noise.
