I've been using the Phantom Spirit 120 cooler for my 9800X3D, but I'm not really comfortable with the temperatures I'm seeing. My idle temperatures range between 47-53°C, and while my system temp is around 36-38°C, I would prefer better. I found that my coworker's ASUS 280mm AIO keeps his idle temps at 31-35°C, and I hit a peak of 93°C under load when downloading shaders in 'Where Winds Meet.' Generally, while gaming, I see temps between 50-65°C, but I haven't really tested any CPU-heavy games yet. I want to understand if my cooler isn't strong enough or if it's a thermal paste issue, since I did it using the cross method. I'm also concerned about my case cooling setup, which has three Noctua intake fans and one exhaust. I'm considering switching to a different cooler and would like suggestions that can give me peace of mind without breaking the bank.

From what you described, the Phantom Spirit 120 should be adequate for your 9800X3D. But if you feel the need for a cooler hug, a 360mm AIO could help – just pick one that doesn't require extra software. That'd save you from any headaches later!
I think you're worrying too much! Those temps are acceptable for Ryzen CPUs. Even if your friend has a cooler giving lower idle temps, it doesn't mean yours is bad. You could try improving airflow in your case or even adjusting your fan curves to get more cooling heads but really, I wouldn't rush into buying a new cooler unless you see performance drops.
Your 50-65°C while gaming is perfectly fine. But if you want to push for even lower temps, consider undervolting your CPU. It would help lower max temperatures without really affecting performance! Just be mindful of the cooler you choose if you decide to buy one. I've heard great things about the Liquid Freezer III if you want something reliable.
Honestly, those idle temps you mentioned aren't a huge deal. Many CPUs run hotter under load, especially during demanding tasks like shader compilation. If the CPU isn't throttling, then you're in a good spot. But if you really want to explore options, perhaps a liquid cooler could offer a bit more headroom, like a 360mm AIO. Just remember that the 9800X3D will have higher temps regardless of the cooler used!
If you're still anxious about those temperatures, maybe look at swapping fans or trying one of those premium cryo coolers. Although, I'd just say stick it out as is. Your setup sounds decent, and if you want to switch coolers, just be prepared that it may not lead to a major drop in temps.
