A:Answer It's been running around 40-50°C for me, and occasionally I've seen it hit 56° but never higher. I haven't upgraded anything yet, but I am going to be getting a better cooling system eventually. Overall it works pretty great out of the box and the case has plenty of room for upgrading. Unfortunately, the motherboard only has one GPU slot but it works well enough for me with a 1070, at least for now.
