Just to mention the Arctic Cooling A35 A-RGB was reviewed today from Mike's Unboxing & Reviews (Youtube). He's done some initial testing and found using a Ryzen 3900X it performs about 4 to 5 deg worse than a Noctua D15 (which is an excellent result!), and he's expecting it to be sub £40 when released (listed at 40 euro apparently, so whatever they convert that too). Could be an excellent mid-tier air cooler.
