5.1. Fan Operation (Semi-Fanless Mode)
The FSP Dagger Pro 850W features a semi-fanless design for optimized low-noise operation. The fan will remain off (0dBA) under low load conditions (typically below 20% load or <25°C internal temperature). As the load increases, the fan will gradually spin up to maintain optimal temperatures, ensuring quiet operation when not under heavy demand.
