Will This Overclock Significantly Reduce the Life of my GTX 980?

Hello all!
Finally done with my extensive testing on my GTX 980. This is the first time I have ever overclocked anything, so hopefully I didn't mess anything up haha.

I used EVGA Prevision

I started with an EVGA superclocked GTX 980 with the ACX 2.0 cooling system.
My stock clocks were:
1266 GPU
1404.8 Actual Boost Clock (Measured with GPU-Z during gaming, is listed as 1367)
7010 Memory

My overclocks are:
1405 GPU (+139 MHz, 10.98% increase)
1543.3 Actual Boost Clock (9.86% increase)(Measured with GPU-Z during gaming, is listed as 1506)
8350 Memory (+670MHz x 2 = 1340MHz, 19.12% increase)

My temperature during benchmarking with Unigine Heaven never goes above 63, and during gaming on Evolve never goes higher than 65.
(And I could make these much lower if needed, that is with fan at about 50%)
I set-up the following custom fan curve
(Note that the fan is inaudible anywhere under 40% power)
0-40=0%
50=15%
60=35%
65=60%
85=100%

I have set my power target to 120% , and during Evolve gaming it just barely touches that during the peak of battle.

I did NOT alter my voltage at all, during stock testing my peak voltage was 1.225, and now it is still at 1.225 MAX


What do you guys think? I would like for this card to last probably around 4-5 years, will this OC put me under that?
Is my fan set-up good, or does it need adjusting?
(Before setting the custom fan I would get to 75, and Unigine Heaven would crash at much lower clocks)

If I kept my card even cooler( say 55 and under) would I be able to get any higher clock?(Just curious, I'm more than happy with where I'm at right now)

Thanks for any answers! Like I said, this is my first time OC'ing and I'm super paranoid about messing my card up.

Oh, also here are the comparison charts of my before and after OC's FPS on Evolve:
(Left two charts are using SMAA anti-aliasing, which was much less taxing than TXAA in some of the other tests I have done)

If I go much higher than where I am I start to get artifacts, however I know when I was hitting 75 I would get artifacts at a much lower clock than where I am now with the 65 temp.

I'm wondering just how big of an impact the temperature has on the stability, perhaps I'll test for the experience, but probably stick where I am.To get under 60 during gaming my fans are gonna be running over 60% and while they are inaudible below 50%, they get loud pretty quick...I've only had them up to 70% and the very idea of them at 100% terrifies me lol.

Well, overclocking common risks is high temperature, that is why people who plan to over locker get a good motherboard and a good cooling system. Your temperatures are great and you can probably go for more if you are only getting 65 C max. I make my SLI confit run at 80C max to ensure that I am getting what I need out of them and staying on the safe side. Good luck, hope I helped!

Are you setting the temp to not go above 60 C?

Leave it at that then, unless you are annoyed by the fan noise that is, but in terms of cooling I'd say your good. Don't worry about the fans running at 75 % in intense gaming, but yes if it gets to %100 constant you should probably check your temp and report back.
Edit: I doubt you will get better Overclocking if you made it run cooler, usualy when you overclock too much you will notice a lot of heat increase and that is when the cooling comes in, but say running the fans at 80% will not increase your Overclocking potential.

Alright, I also just thought of something as well that I need to consider...The faster the fans spin the more power they will use. The card limits itself at 125% TDP, and my power target is 120%, which I am already touching from time to time.
The fans don't use much power compared to the card itself, but I'm already at the edge of where I'm willing to go, so an increase in fan speed might put me at the 120% power limit more often, which would equate to throttling by the GPU.
(I assume all this from the limited research I've been able to do, by all means if I am incorrect anywhere let me know! I want to learn about this stuff so I can make educated decisions in the future)
