I have a AMD R7 360 2GB that is hitting 99°C for a second or two while playing heavy requirements games. Is my pc at risk? I only play for an hour or two like 4 days a week. I tried lowering graphics but it didn't do much. After going to 99°C it lowers to 90, then goes slowly up to 99 again. I would say that it happens 1 time every 15 minutes.
