Have a Asus Maximus Formula Se board.

Have a stable over clock at 3.6ghz on a Q6600. Now I want to lower the CPU voltage. It was at 1.45625V but I want to get it lower, i've Prime95'd it so far to 1.38750V stable.

I wanted to ask what CPU PLL Voltage is exactly and if that will also help with temperatures. Should I leave it at 1.50v or lower that slowly while at Vcore of 1.38750v and continue to prime it?
