Should i raise powerlimit to 110% in msi afterburner?

[xYowie]

I have a evga gtx 960 4gb thats 6 months old and overclocked to +150 core +300 mem without touching voltage and it runs at ~70c, should i raise the powerlimit to 110% to overclock further? i dont plan on using it for more than a year because pascal and stuff.

if you dont plan on needing it for more than a year try to get it cooler then mod the voltage and get a real oc on it
