I've been out of the PC building scene for a while and I'm considering putting together a new rig. I'm curious about the reliability of AIO closed loop coolers because I've heard quite a bit about leaks in the past that could damage components. I want to make sure it's a safe choice this time around. My goal is to overclock my 9800X3D, but I'm concerned that air cooling won't give me the results I'm after. Have AIOs improved enough that this issue isn't commonly discussed anymore?

AIO coolers have definitely gotten more reliable over the years, but there’s still a small risk of leaks. For a 9800X3D, a decent air cooler like the Thermalright Phantom Spirit should handle overclocking just fine. Honestly, with today's chips, manual overclocking doesn't provide the same gains as it used to, so don't stress too much about it.
I've had a Cooler Master AIO for 5 years with no problems, even in a less-than-ideal case position. Just make sure you stick with reputable brands like Arctic and you should be fine.
If aesthetics aren't your priority, a solid air cooler like the Phantom Spirit is more than sufficient. Just remember that good case airflow is essential; there are great budget cases like Lian Li 216 that manage airflow very well.
I've been using an ROG 360mm AIO for my 7800X3D without any issues. I've found that undervolting gives me a solid boost in performance, and having a larger radiator definitely helps with cooling. Just avoid the smaller AIOs; they won't be effective.
Leaks are less of a concern now, but keep in mind the pump might still fail or you could run into air bubbles, which can affect cooling performance compared to air coolers. Generally, air cooling is just simpler and often just as effective.
