A:Answer I'm pretty sure the cooling and all of the fan case are works with full power. The GPU overheating and hit 85 degrees, when I took out the tempered glass sides panel, the degrees decrease to 77 degrees. My PC only come with 2 fans, 1 exhaust and one intake. The GPU is Gigabyte RTX 2080 Super Gaming OC White. It is the over $1500 PC. I'm pretty sure because of the bad of cooling system.
