I have a gtx 770 in my build. I play overwatch at epic settings and average around 70fps. My average temps started at around 80, which after extensive reading I concluded was fine, Though I installed one more pc intake. The next day it started to run up to 88 or 89 and averaged around 85. I read about specifically the gtx 770 and saw that this can be harmful. I cleaned took apart the cooling sytem on the gpu (Asus triple fan) and I replaced the thermal paste and cleaned off all the dust. No change. Any ideas?
