All depends on your plans for OCing. A hyper 212 EVO generally will cool better or at least as well as most AIOs up through a H100, if going to do so would go a 240 AIO, and keep in mind they are often noisier than a good Air cooler. The Lepa Aquachanger 240 is pretty good and on the quieter side, they also have a new model coming to release called the EXllusion which is very good, have one on my Z170 Hero/6600K right now and it's the best I've had on this so far (which includes trying a 212 EVO, and Cryorig H7, the Lepa Aquachanger, a Seidon and a GTS V8) (been playing alot 😉 )
