First impression: that fan sucks more power than the RP5 iteself!
2nd impression: there is no point in arguing about any RP5 peripheral, because the RP5 itself is mostly a toy!
Personal take: I mostly like SBC like the RP5, when they are 100% passive and silent; won't ever clog or overheat even after years of abuse in some forgotten niche.
I'm glad my RP5 seems to do even better than its RP4 predecessor: I've got a 100% passive chassis that won't ever have the RP5 throttle, no matter what I throw at it. It's nowhere near room temperature, but then silicon feels rather comfy at 80°C!
I personally can't think of anything that would improve on that, except computers that run on harvesting global heating.
But then there are people who do RGB and water-cooling simply for the looks and fun...
...and there is no point in arguing with them: chacon son goût or de gustibus non est disputandum.
