Is my system running too hot?

[ksiazka15490]

So recently i upgraded i had a 1060 ssc from evga and i never saw temps above 65 on it on afterburner, I bought a Zotac 1070TI Mini the other day and have been gaming on it. I overclocked it in afterburner and it was getting good scores on firestrike in 18000+ But now when im gaming on it without the overclock. My cpu is at 55C and the gpu is seeing 75C max after playing metro last light for 8 hours straight. My question is this okay temps/ im worried 75C seems very hot the system fans dont get loud and stay quiet and im scared/nervouse to put the fans on 100% do i need to raise the fans? or keep them on auto? this is my very first computer build and im just uneasy and dont want to ruin anything, also is their anything i can buy that will reduce these temps -10C? Im just very nervous i feel like i put alot of mopney over 1200$ into setting all of this up and now the machine is getting hot never had problem with 1060ssc, also any tips or anything you guys can recommend anything to improve performance of pc or what else should i upgrade? any tricks or ways to get good cooling? also is 16gb of ram worth it? thanks again and sorry for the long post

To be honest I don't see that as much as a problem. Metro for 8 hours and only maxing 75c is pretty good relatively. Just make sure it doesn't get hotter and the fans are running. Some cards have drivers you can use to customize fan control if you're really worried about it. As for the Ram, yes 16gb is worth it. It's the new standard for games, and some are even pushing for more but 16gb should be good for now.
