Even something like an arctic freezer would be perfectly fine for the 3600 and even a 3700x.The Phanteks Enthoo Pro M has a 5.25" bay and has a mesh front. Out of stock though at the minute. Also you could go with a cheaper cooler as the D15 is overkill for an R5 3600. The Scythe Mugen ones are good for the money.
