Edit Reason: at a consistent

Is it better for the fans (NOT THE UNDERLYING CHIP) to run at a constant speed or a variable speed dependent upon the temp of the chip?
Basically I want to know if it is better for me to run my fans at 80% speed from 50 to 60c temp, rather than running a variable speed from those same temps from a 40% fan speed to a 100% speed. Meaning the fans change speeds dependent upon the temperature.
The result in real time in my rig is the GPU runs a little hotter on average when the fans are locked at 80%. AKA: 80% = 56C top temp and average temp at 55C while gaming.
When I run the variable fans the temp is largely the same. But it dips lower. So the top temp is 55C and the average temp is 54c. On paper that looks like the better option. However to make that happen requires the fans to be shifting speeds almost constantly. As the fan curve is set from 50c to 60c. So the fan runs anywhere from 70% to 85%. Adjusting on the fly to accommodate the GPU temp.
Thus my question. Is this going to reduce the longevity of my fan system? Does running at a consistent rpm longer provide longevity or does it not matter and running variable speeds have limited effect on longevity?
