I think its ok just for that. I mean anything is possible but I doubt one boot with a non stressful test like everest will do it in , especially with good temps and no 100% or even close to 100% cpu usage. I suppose there is an inherent risk of course though even one boot and one test but its a risk I felt was acceptable. In a year I doubt I will even own this cpu and since when I bench or use 24/7 my settings are safe I am not worried.
I have actually read even higher volts on auto in some screens and on air and/or water and not cold. I wouldn't do any stressful benches at those settings, but that's just me.
