can i download w11 iso from microsofts official site and still use MAS afterwards? or do i have to follow the rentry guide that directs to magnet link/massgrave site

aight welp, i ordered >>106408972 5070ti not in stock so 2~ish weeks. Frame 4000D comes with 3 front intake fans, and i ordered 1 120mm exhaust fan, but im wondering if i should have another exhaust fan mounted at the back top aswell? directly over the cpu cooler?
