Re: Question regarding GPU temp.
What's the temp of your room? With summer getting warmer, if your room/house is warm, yes it will affect your components, especially if you don't have proper ventilation.
51C is getting high, but not bad. GPU's are pretty safe up to around 80-90c, if I remember right. I would look into trying to cool your room down, and getting some better airflow through your case (maybe crank up the GPU fans as well, with something like EVGA Precision).
