    From Michael Larabel's hard work, and by The Raspberry Pi Foundation's tacit admission, it is quite clear that the RPi4 is not usable without the addition of proper heat sinking;
    I'm inclined to agree (and "liked" your post) but there is another argument to be made.

    The Pi 4's performance might be hampered without proper cooling, but it still might be good enough and an improvement over previous models. It's priced the same, so: hey. RPi was never about sheer performance. And there are other reasons to go with the Pi 4 over previous models: fast networking, dual HDMI, multiple USB 3, etc.

    Another way to think about this is that the RPi 4 has performance "headroom" over its out-of-the-box experience if you're able to invest in cooling for your money and use case. It's a bit offensive because this isn't overclocking headroom, but rather achieving the normal operating potential of the silicon, but the end result is really the same. Out of the box you get X, and you can improve it to Y with better cooling.

    You buy a Pi for entirely other reasons than performance, and they really are all wonderful reasons. So I consider this still to be a good product, but I wish they were more transparent about the cooling requirements in their released information because obviously it left a bitter taste in the mouths of some of us.

    that's $79 vs the $70 for the equivalent rpi, that's only 11%.
    The N2 already comes with the heatsink?
    • N2, DDR4@ 1320Mhz, $79
    • RPi4B, Ram speed?.. CPU is caped at 1.5Ghz is $70
    • RockPi4A, LPDDR4@ 1600Mhz, plus its CPU works @2Ghz.. $65
    The N2, costs 21.5% more than RockPi4...

    RockPi4 and RaspberryPi, doesn't have fan connector, big fail..
    N2 has...but it has the Fan header in the Top..with CPU in the bottom..

    N2,RockPi4 have a cleaner top, since the CPU is hidden..
    How people will run in full load, during months if they need too on N2/RockPi4/RaspberryPi4..??

    From the 3 Boards, clearly RockPi4 is a winner( but it should also consume more power tough... )..

    Exactly..
    rpi is not a product made to run full throttle continuously..
    Using fan on gpio, is not so critical, but running it at 5v, its around ~30% less efficient, and no pwm..

    How warm is the FLIRC case itself under heavy load? I definitely want my Pi to be fanless, unless the case becomes too hot to even touch.

    The community is better because there are not millions of unanswerd posts like on the rpi site.
    Yes it runs Debian, Fedora, Arch and their derivatives. Kodi, Android, mainlin Linux, etc.

    All RPi s have been making Odroid stuff look cool for a long, long time. Even now, the lowly XU-4 ( 2 GHz, EIGHT CORES; 2 GB RAM; eMMC; SATA3; TRUE GB ethernet; Real-time Clock; and it comes with a fan, or large heatsink--your choice) sells for only $51.95.

    All RPi s have been making Odroid stuff look cool for a long, long time. Even now, the lowly XU-4 ( 2 GHz, EIGHT CORES; 2 GB RAM; uses eMMC for on-board mass storage; TRUE GB ethernet; Real-time Clock; true SATA3 interface for easily adding a HDD or SSD; and it comes with a fan, or large heatsink--your choice) sells for only $51.95.

    ODROID-XU4Q Also consider the ODROID-XU4Q which has a passive heatsink Check our Home Assistant Bundle ODROID-XU4 Check our Home Assistant Bundle ODROID-XU4Q Big power in a small package! The ODROID-XU4 packs an octa-core Heterogeneous Multi-Processing ARM CPU, 2GB of high-speed RAM, 2x full-sized USB3.0 ports, Gigabit

    Going bellow 28nm, is very costly..
    28nm nowadays, its the sweet spot, everybody that tries to do something serious goes 28nm, if he can..
    Bellow that, only Large Scale productions, of products that sell at least for some several hundreds €..

    Amd and Intel do it, because they are the monopoly for x86..
    In the graphics market, Amd and Nvidia can also do it, because of graphics monopoly/high price of the products..

    Apart from this, only large scale cpus for Mobile Phones, and such goes bellow 28 nm..

    China that is China,
    Maybe will next year start sampling its Loongson 3C5000 at 16nm TSMC, and its a country with more than 1 billion people..but not enough for the required scale to go..lets say 7-12 nm( has the final product would cost a fortune each.. ).
    Russia, the same, they are working at 28nm, expecting to go 16nm in 2021..
