I built my first ever pc and it crashes after playing graphic intensive games such as bf4, fallout 4, the Witcher 3, etc. Games such as DayZ run fine on pretty high graphics. If I set the gpu fan to 75% the games run substantially longer before crashing. Specs are fx 8350, gtx 960 ssc 2gb, 8gb ddr3 ram, msi 970 gaming mobo, cx600m psu. From my research these specs should be able to handle ultra to high graphics pretty easily. I only have one 20mm case fan and the stock cpu cooler. If anyone has any clues as to why I am having these problems, I would greatly appreciate any feedback. Also I have unparked my cpu cores if that makes any difference.
