After installation, the software is stated to start automatically with the computer and remain running in the background.

The fan uses PWM control, so its speed adjusts according to motherboard temperature without manual adjustment.

Confirm your platform is one of the listed AM4, AM5, Intel LGA1700, LGA1851, LGA1150, LGA1151 or LGA1200 sockets. The digital screen depends on the motherboard’s 9-pin USB connection and TRCC software, so both should be in place for display use.
