5. Istruzioni per l'uso
The Cooler Master V550 Gold V2 is designed for reliable and efficient operation.
Semi-Fanless Operation
This power supply features a semi-fanless mode. The 135mm Fluid Dynamic Bearing (FDB) fan remains off under low load (up to 40% of total capacity) to provide silent operation. As the load increases, the fan will automatically activate to maintain optimal temperatures.
Interruttore ibrido
A hardware-based hybrid switch is located on the rear of the PSU. This switch allows you to manually toggle the semi-fanless mode on or off.
- Accendere: Enables semi-fanless mode (fan off under low load).
- Spegnere: Forces the fan to run continuously, regardless of load.
