@kbin.socialOups, I misremembered: the game is called Core War. In it, MARS ("Memory Array Redcode Simulator") is the name of a virtual machine that executes Redcode instructions. As a player, you write small programs ("warriors") to be loaded on the virtual machine where they try to prevail while klling off (overwriting) opponent programs.
I thought this would be more like MARS, but turns out to be bare-metal MARS Core War where I'm the scheduler. I'm not saying it a terrible experience, but I am grateful that my day job in IT is more higher-level.
They would likely perform worse. If ("if", ha) those fans are not in perfect sync, they're going to obstruct airflow. Also, consider that each fan introduces both audible noise and perturbations in the airflow which in turn, also will cause noise.
Incidentally, I have (almost) that very same case, an Antec P182. Mine has a super-quiet PSU fan, and a ginormous heat pipe cpu cooler (HR-1 if you're curious) with one fan ... and that is plenty.
