Just assembled the AIO and right from beggining it is performing much worst than my previous Ryzen 5 5600X with an original air cooler (I guess it a Wrath). Iddling at 71C/159.8F. Liquid temp at 57C/134.6F Easily goes up to 90C/194F and stops there because of throtling, I guess. Do I just got lucky an got I bad AIO or a 240mm is not sufficient to cool down an 5800X3D? If it is the first case I just have to by a new one: this one I receveid from my uncle in USA, I 'm living in Japan and just don't have the invoice to claim an RMA. IF I need a 360mm AIO I'm also in bad luck: there is no space for it in my case and have to think in Air coolers.... Thinking in going back to the Wrath of the 5600X... Any suggestion is very welcome.
