My gpu at max load is in the mid 70's and the fan speed is in the 50's, should i set a aggressive fan curve or should i be fine at my current temp, noise is not a problem at all i just dont want to wear out my fans : / lastly, what is the average lifespan of a gtx 1070 with moderate use? (typically its never at full load, just did a stress test and normally when i game its in the 50-60's)
