My specs are 13400f, 32 gb 3200 rams and xfx quicksilver 9070XT and also i have XPG defender pro case

Panel on, gpu fan speed 1300 rpm, gpu temp 63C hotspot 77C, cpu temp 59C..

Panel off, gpu fan speed 1130 rpm, gpu temp 62C, hotspot 75C, cpu temp 55C..

it feels like it has a huge impact, is this just a very bad case design or what? When i remove the front panel i can feel the hot air stream upon my arm for a sec but then it goes away, i dont even know what to make of it, obviously its not the end of the world but im just scared using the pc this way will significantly increase the dust build up also it doesnt look slick,
