Well depending on your budget and looking at the case, the corsair h100i would be a good choice. You can place the radiator/fans inside the top of the case. Or if you prefer rear exhaust, the h80i corsair will do good as well. There are other similar models out there too, but I personally prefer a household name like Corsair/Kraken as I know I'm getting good quality. Though accidents can happen!
Subjectively, again, if I'm not planning on overclocking a build I opt for an air cooler as there isn't a lot of difference in temps until you ramp up the volts/frequency on the CPU.
