Reducing the pressure around the final AIO fan, taking away perfectly cold fresh air that just entered and has done nothing from being used by the AIO. Again, the AIO fans when mounted on the top is the primary exhaust. Any "ambient heat" from other components goes out that way just fine. If a hot GPU and SSD causes the CPU to heat up a bit because the radiator is now getting warm air passing over it, that will just trigger all the fans to ramp up and solve the issue. It causes the AIO radiator to function as a general temp sensor for the whole system.
