Considering this, should my AIO be intake or exhaust?
1. AIO cooling CPU. If it gives off crap tons of heat like the 9900k, then better as Intake, since the CPU relies on being cool enough to run and boost. Otherwise, Exhaust is better (especially if the AIO can cool your CPU to a low enough level even with the hotter air it Exhausts out).
Furthermore, is push or pull better for radiator? A Push configuration is more efficient in cooling when its blowing cool(er) air from outside the plenum through a radiator. A Push also makes your build louder. In Pull configuration the fan or fans are drawing an air stream out of the radiator.
Subsequently, one may also ask, where should you mount your radiator?
Do: Mount the radiator so its airflow is not impeded by other devices in the machine. One of the best spots on a machine is the top of the case. Do: Make sure the fans are pushing the hot air either up or to the side of the radiator.
Are 120mm AiO worth it?
No, not worth it. As mentioned, Hyper 212 EVO or similarly priced Cryorig would do fine. If you want to spend a little more, for $45 you can get a Thermalright True Spirit 140 Direct and it performs like a Noctua NHD14/15.
