Till it all gets to temp then it won't do much. It needs some more surface area to convect heat better.

With enough fins you don't need fans.

    Would a slow small fan still make a huge difference to the cooling here? Completely passive cooling seems like something that would only make sense in very specific professional environments (like needing an ultra low sound floor in an audiology chamber or recording studio).

    I had a roommate who was getting his doctorate in chemical engineering, specifically focused on graphene. He was able to demonstrate how doping the materials in a heat sink to alter their ability to "release" heat, and then organizing these intentional hotspots along the length of the fins, you could create an active airflow using a stationary object.

    But then his lab manager killed his grant and instead put him on a project partnered with BMW to make their bumpers more marketable.

    Really makes you wonder how many revolutionary ideas have fallen through the cracks because of moron management

    Many folks in higher education in the UK have been bemoaning a generation of genii lost to business and the City who put their talents and creativity to the good of making profit rather than inventing and humanity.

    Many more have their funding and direction tilted to capital, too.

    If you're a Mathematical prodigy you either become a Quant making mathematical models for Price and Risk of Over The Counter (so, not sold in a Market) derivatives or, if you have good salesmanship skills, a Trader of such financial instruments.

    None of this brings any actual improvement to Mankind but it sure pays well (more the latter than the former) since the way our Economic System is structured and as a side-effect of unbalancing the playing field to make sure the wealthy get ever more wealthy, Money is the thing that makes the most Money, and even just a tiny slice of such flows is far more monetarilly rewarding than almost all other forms of creation or discovery.

    The case has an opening for a vertical fan but it is not needed unless you do heavy gaming and run a high end GPU. For video rendering and other tasks the fins are rated to keep it at a decent temp.

    I have good hearing, and a HDD spinning or even a "silent" fan is still audible droning noise to me.

    This build is totally silent. The PSU is over-rated on purpose because it has a below 30% max draw mode that is fanless.
    So this case makes 0 noise.

    Is your motherboard connected to two giant case-sized heatsinks? I'm struggling to see the big picture here
