Damn that case is lol...
Alright then your temps looks normal for what you got, though maybe slightly on the hot side. Try setting a fan profile in MSI AB but with that case and the CPU cooler blowing right on your card, you wont manage to get much lower temps
A good airflow in the case is critical. Even by changing stock fans on my 800D I got huge temp drops on CPU and GPU. (stock Corsair 800D fans and configuration is very lacking).
