Overclocking my GPU, keeps crashing, why?

I have a factory overclocked titan black that I use evga precision to overclock a bit more, I get up to 1116 boost clock. My problem is this.

If I put evga precision fan on auto, with power setting and temp setting to the highest, there's just no way that clock is stable, benchmarks and games crash after a few minutes and I never see the card get that hot, in fact the card has a great cooling solution, my case is perfectly vented right under the card's agx cooler and I also have a backplate.

It shows temp target 95c, which means it should be getting up to 95c before it starts to throttle or whatever but I don't even see it getting near 80 before the crash happens.

Now if I manually set the fan to 70% (or more, obviously) the same clock is perfectly stable, I get big scores in bench tests and my games never crash.

I don't understand, what good is the auto fan setting if it doesn't seem to catch up to the card's heat before it crashes? Or maybe this isn't the problem at all, after all I don't see the card get that hot in the first place.

Sure the solution is to have 70% fan in my OC profiles and that is it but I want to understand whats going on with the auto setting.

Thanks.
 
Solution
GPU Boost 2.0 is rubbery to say the least at times.

Maybe precision is set to get more out of the card than the card is happy to deliver. gpu's do vary.

Try Afterburner.

Gpu boost 2 says that it uses a user defined temperature target, when in fact it just goes to 80 and throttles. So if your core is on 1110 and your temperature target is set to 95, your card will get to 80 and then throttle anyways.
