That parts themselves won't get too hot, but that heat ends up trapped in the case unless there's enough ventilation. Also in hindsight if OP doesn't know what computer to buy he probably has no clue about fan curves.It really won't get loud at all. The cooler is massive overkill for the CPU already and the GPU is, uh, a 6700 XT, a 230w card, and it has a fan pointed right at it for that case. It's fine. Worst comes to work, he can buy an extra fan or two for like 20 bucks.
