Thanks! I like the easy upgradability (for example upgrading the extruder without much hassle). I read that 5020s have lower static pressure, and need to be run faster. I'm going to use sunon maglev everywhere anyway, so sound is unlikely to be an issue. I have an Ender 3 v2 and want to print with giant sized nozzles. Already have a dragon hf and am using it with the youmaketech bmg upgrade. But the included duct does not cool evenly from both sides, so I decided to switch to Hero Me. Cheers and happy printing!
