Heyo. In my country (Hungary) the Assassin IV is available this week. Mine came yesterday, upgrading from an Arctic eSport 34 Duo. I am cooling an 5800x3D CPU. https://i.imgur.com/EgLco38.jpg

>Pros:

With the 5800x3D it lowered my Idle temps by 3-4 C°, the Load temperature by 8-10 C° (Depending on Game). Sadly the 5800x3D still reaches 90 C° quiet easily in CPU heavy benchmarks (CPU-z, Cinebench) on stock PBO2 settings

Noticeable quieter than the 34 Duo (even in Performance mode. I just leave it in Quiet mode. There is only 2-3 C° between the modes

I love the design and you shouldn't have any RAM clearance issue because the cooler expands to the rear instead over the RAM. This however cause a minor problem for me, I had to remove my exhaust fan (Arctic P12 PWM). Technically my case doesn't support any CPU cooler above 160mm (This one is rated for 164mm) however it still fits inside but without the real fan (P400A case)

Came with 1.5g DM9 by Deepcool.

>Cons

Beside the mentioned rear fan clearance issue, the cable situation is kinda bad. Each fan inside is PST, however the cables are a bit long. I had to tuck them behind the cooler
