3. Instruccions de funcionament
Once all connections are secure, plug the main power cord into the power supply and a wall outlet. Flip the power switch on the back of the PSU to the 'ON' position.
3.1 Funcionament del ventilador
The XPG Core Reactor II VE features an FDB (Fluid Dynamic Bearing) fan with intelligent fan control. This system is designed to optimize cooling performance while minimizing noise. The fan may operate in a semi-passive mode, meaning it will not spin at low loads to ensure silent operation. It will automatically activate and adjust its speed as the system load and temperature increase.
