Every AIO I've ever owned has stopped working not too far into its life. I remember being shocked and dismayed the first time I had one fail, and simply upset when the second one failed. After the second failure, I bought a Noctua NH-D15S and that heatsink has happily survived 4 builds. (Only getting replaced after I switched to Threadripper, which required a different Noctua heatsink. But don't worry, the NH-D15S still lives on in a friend's PC.) In my opinion, there are two viable cooling solutions: a high-quality heatsink and fan, or a custom water loop. AIOs just don't have the performance to make the failure rate acceptable.
