I have 2 x gtx 980's that boost to 1550 on air without extra voltage. Is it safe to run them like this 24/7 as temps still stay under 70c or is it best to bring them down to stock when the oc is not needed.
that they are stable, and temps are fine (also temps on vrms are fine) they keep them at that. Just run Valley benchmark and loop it for a few hours, also make a custom fan profile if you really want to bring temps down even more use MSI Afterburner for this. As long as you get no driver crashes, or artifacts and temps are fine leave them at this overclock. More performance is always best, at these speeds these cards should kick ass.
