gaming usually maxed out at 80 on the high side, some games only 75, as for the voltage, Im no overclocking master, and to be honest I didnt test as thoroughly as may be i should have, so no i may be able to drop the voltage a few milivolts. but for sure at 5ghz i wasnt stable under 1.380, but thermally throttled in Aida so I dialed it back to something I knew would work. Anyway, ive done some research and found that short of going push pull ont the rad, thats about as good as im going to get, thanks all for your help.
