If your BIOS doesnt allow vcore control, then i am afraid you cant do much about it.
Also regarding the CPU running hot, have you looked into the ventilation of your case ? If its not right, recitfying it will improve the cooling efficiency for sure.

remove proccy HSF,clean all the dust,remove the thermal paste from both the procy and hsf and then reapply thermal paste and install the hsf.
