CPU_FAN1, PUMP_FAN1, SYS_FAN1~2 : Connecteurs
de ventilateur
Les connecteurs de ventilateur peuvent être utilisés en mode PWM (Pulse Width
Modulation) et en mode DC. En mode PWM, les connecteurs fournissent une sortie
de 12 V constante et ajustent la vitesse du ventilateur avec un signal de contrôle de
vitesse. En mode DC, les connecteurs contrôlent la vitesse du ventilateur en modifiant
la tension.
