Methods and apparatus for mitigating temperature increases in a solid state device (SSD)

The present disclosure, in various aspects, describes technologies and techniques for a controller of a data storage device to mitigate temperature increases in the data storage device. In one example, the controller receives a command for a memory operation, analyzes the command to determine whether execution of the command with thermal throttling would have a negative impact on a user experience, and activates, if performing the thermal throttling would have the negative impact on the user experience, one or more thermoelectric cooler (TEC) devices while refraining from performing the thermal throttling. In another example, the controller monitors a temperature of one or more regions of the data storage device, determines whether the temperature exceeds a threshold temperature, activates one or more TEC devices to mitigate the temperature when the temperature exceeds the threshold temperature, and deactivates any activated TEC devices when the temperature no longer exceeds the threshold temperature.
