Hi, Im building my first gaming pc. So in short... My cpu case doesn't support aio liquid cooler on upper side because of low space. And the cpu case comes with 4 pre installed fans (3 on front side and 1 on on rear side) so if want to install an aio on front side should i have to replace those pre installed fans with aio fans? Or is there another way to install the aio Without replacing those pre installed fans?
