Is this bad for my gpu?

I own a 6750xt QICK 319 SPEEDSTER, i bought this gpu second hand and it doesnt have any warranty left... The gpu works perfectly fine but im just worried about the temps: My avg gpu temp is 60-50c while under load but my hotspot temp is avg 75c, it sometimes even hits 80-83, my fans are working at around 2k-1.5k rpm... Personally i dont care about if the gpu runs that hot but im a bit scared that it will do some damage to my gpu, as in performance loss or something like that
