Installed on 3700X inside a mATX case, albeit on the slightly larger end (Corsair Obsidian 350D). Despite it seeming quite big, and it is chunky, there is still quite a bit of room around it. A second fan for push-pull is possible, though I hardly think it's generally necessary.

I got a 5-15C temp improvement over the Wraith Prism (bigger improvement for higher power) in addition to no noticeable increase in noise under moderate loads.

The included magnetic screwdriver is also huge win, something I would expect to easily cost around R200 at a hardware store. It's necessary because of the way the it's installed, but it will be very useful for reaching motherboard screws in tight corners.

I moved from the intel stock cooler to the Mugen on the I5 12400, all I can say is under an all core workload temps went from 89C to 58C. You be the judge if the temp improvement is worthwhile. (CPU did not throttle with stock cooler). But my room no longer feels like a sauna and my pc in inaudible now.
