The invention discloses a solid-state-disk temperature control method and a temperature control module. A core idea is to control system performance to achieve a purpose of indirect control of systemtemperature. The method is characterized by dynamically monitoring and collecting the system temperature and the system performance, controlling Flash according to the current system temperature to switch to an running speed, which matches the temperature, to run, calculating and updating a command parsing speed control amount in real time at the same time according to historical system temperature and historical system performance data cached by the module, inputting the performance control amount into an execution module to adjust a command parsing speed of the execution module to realize adjustment of the dynamic performance, and then indirectly realizing a purpose of smoothly controlling the system temperature.
