i have a few questions :

1 - whats the difference betwin Ga-Ep45-DS3 and Ga-Ep45T-DS3 ?

2 - in bios, at fan setings, does it have the Voltage option ? or just auto and PWM option ? .
I am asking this, becose i have a tl blue orb, only with 3 wires , and i dont want it run at full speed all the time . so if it has voltage option the speed of the fan will depend on temperature ( lower on iddle, and high on load )

Tnks
