Thinking it could be PSU overload? Only seems to happen in Overwatch, about 10-20 minutes into a game. Only started happening when I upgraded to a 1080ti and Kraken G12 + Corsair H105 cooler + fan splitters. PSU is an Aerocool P7 650W (platinum) - 8086k (was OC to 4.8, now back to stock) - 2x 240mm AIO for CPU and GPU - 1080ti - 3 SSD, 1 HDD - 7 fans Nearly everything in my setup has RGB, not sure what the power draw from those are. I can't seem to replicate this in Diablo 3 and Mass Effect: Andromeda - the two other games I'm playing; only Overwatch. GPU and CPU temps are 50-65 degrees.
