Tried Fumark after 100% Fan, I have fps locked at 60fps, I have to figure out why (I think xbox app) , It's the first Nvidia Gpu after almost 3 years:
EDIT
Find out fps lock issue: disable xbox gamebar.
Even better, nice boost clock, lower temperature:
EDIT 27/10/2017:
Tried Prime95 after almost one week, 4°C lower, medium 2/3°C. Thermal paste "curing" takes effect?
Prime95 + Furmark!
Pc case stay really fresh also stressing both gpu and cpu, the only part warm is the gpu side.
Like TekEverything said, this gpu push a lot of air on case front hole
