    Im Moment aktuell noch überhaupt nicht nötig aber wollte es trotzdem hier mal vorstellen.

    Auf dieses Board und auch genauso auf den ROCKPro64 passen ganz normale NorthBridge Kühler. Hier bei diesem Modell könnte man noch einen Lüfter drauf schrauben. Da ich keine Lüfter mag, mein NAS auf ROCKPro64 Basis hat auch nur einen Kühlkörper drauf, kommt da auch nie einer drauf.

    the ram chip is higher as the cpu 😉

    @thc013 I use an thermal pad. So i think it isn't an problem.

    Peters Image benutzt ein Debian Buster 10

    Kernel

    Gut an diesem Image vom Peter ist der funktionierende PCIe Port 🙂 Nicht so gut ist das Image, wenn man längerfristig damit arbeiten möchte. Der Aufbau ist dafür nicht wirklich gut geeignet. Wenn man das möchte, dann benutzt man lieber das Manjaro Image. Das wird gepflegt und man bekommt alle Änderungen und Patches auch geliefert.

    Ich hoffe, das die PCIe Patches auch bald im Manjaro Image ankommen, doch dafür müssen diese Upstream sein weil das Manjaro diesen Kernel nutzt (linux-rc). Und wie ich heute Morgen gelesen habe, es besteht Hoffnung für einen funktionierenden USB3-Port 🤗
