I have a 7900X3D and the Peerless Assassin 120 worked well. I swapped for a Zalman CNPS20X because you could get it for next to nothing at the time; it’s not much better (the RGB fans look neat but it’s so big it doesn’t fit well in some cases and the fans are prone to chattering noises at specific speeds)

The benefit I can imagine for an AIO is that it reduces cramping around the CPU, so you can essily release RAM or the GPU slot clip. But I suspect VRM cooling suffers; some vendors made an add-on fan to compensare IIRC.
