Taking the side and blowing a fan in there will help lower the temps.. Any fan will do. It will also help the GPU temps, what ever those are. If you don’t crash, then it’s a good sign it’s heat.
If your cpu is oc that can cause crashing too or if your ram speed is to high. Maybe the little extra heat was enough to cause the crashes. All settings don’t always work 100% of the time and one change can cause a hissy fit.
This is more towards if heat is a problem and or adjusting the bios to take care of crashing. And if you raise the game settings and crash, reboot and try again, but if you still crash, then I would go into the bios.
DDU is almost like the three DDD’s.
