Well if your running a 60hz monitor then there's really no need to go higher unless you one of those super competitive FPS ppl that believes they need to have the highest FPS possible (CSGO). Personally I'd keep vsync enabled to whatever your monitor refresh rate that way the GPU isn't working harder then it needs to (keep temps down) and helps reduce screen tearing.
When the temp is down fans dont need start working, but after some time when gpu reachs 60Cº fan start working and when the temp is down fan stop working, My question is can this circle of start, stop start stop start stop, damagins the gpu?
Sorry for the bad english...
