i have a p4 3.0 800 fsb running on a asus p4c800 deluxe and a aiw 9700 pro. my case is the thermaltake xaser with the seven fans but i was having problems running stable just in normal clocking speeds. my temp was about 44 while gaming. well i changed out the 2 rear and 2 side fans no i have my p4 up to 3.5 and the aiw from 325 and 310 to 366 and 342. while gaming the temp only gets to aobut 34 now and no problems now. my question is how do i know what to set the vcore at i have it at 1.6 now but not really sure if i should give it more juice and try and get more ou of the cpu or whatever. just really dont know where the vcore should be. thanks.
