If the hardware supports it, yes. Unfortunately, I suppose your card (i.e. its voltage transformer) does not support higher or even freely programmed voltages at all. Therefore, I think you have to pencil- or hardmod to gain more voltage.

This ASUS has a two wire fan (called Glaciator) and this fan is always running 100%.
I also noticed that RBE shows that the PWM ramp is ON!
-Is it normal to have a PWM ramp ON with a 2 wires fan?
-Will the fan regulate if I change the setting from all-the-time-100% to different values according to the temp?
Thanks in advance for your answers
Edit: I have tried different bios from different manufacturer, but it always comes out with bugs! I guess it is because of the hynix memories chips!
The fan controller is built into the GPU. So even your card has one, and it can be programmed by the BIOS. Therefore, it can be programmed to use PWM ramp or not. However, your card does not use its fan controller for it uses a two-wired power connected fan only. There's no way to do something about it on software level, sorry.
