So as of now my new build is about 2 days old and I've instantly ran into some problems. While idle the CPU temp seems to slowly rose ticking into the mid to high 60s(C*) and while running any games, even on the lowest settings, can hit 95-105 and will just freeze. I only have a 850w seasonic power system and I am well aware that the gigabyte r9 280x requires 600w, it has the wind force 3 fan setup. I've paired it with an AM3+ gigabyte mobo with a 4.7ghz vishera fx-9590. The case has 7 fans, 4 of which have LED. I have a coolmaster hyper-N520 CPU cooler but even with that the whole thing seems to get warm before I even open a browser. Do I need a larger PSU or is there precautions and changes I can take/make to lower the temperature of the parts before ditching my old supply? Thank you in advance.
