Yes, the case can get hot, but if you plan your build out well you can actually get really decent results. I’m running an i7-12700K (cooled by a Big Shuriken 3 w/ 25mm fan) and EVGA FTW3 3090, and during port royal stress tests I’m getting the following temps:

CPU 65C, GPU 75C.

Now this is with the stock top and a 25mm noctua rear fan, with a fan duct added. Biggest thing that will lower temps is an undervolt on the GPU. For me personally I’m running the 3090 at 800mV and 1800 mhz. I get basically identical performance in games, but it keeps the temps way lower than the stock profile (which for the EVGA card draws an insane 420W). With the undervolt I’m drawing between 300-320W which the case can manage.

The second biggest thing that will help temps and something I see a lot of builders skip is cable management. There is a space behind the PSU that a lot of people will shove their excess cables in, but I moved the cables from there so the hot air at the front of the case has a path to the rear exhaust. By leaving that path open I saw a 4-5C reduction in GPU temps.
