I've been running some tests on my CPU cooler, which is a few years old AIO model. I used Cinebench and checked the temperatures with Libre Hardware Monitor. I noticed that my idle temperature is around 25-35 degrees, but under max load, it's hitting a staggering 99.5 degrees. Should I be worried enough to consider replacing my AIO cooler?

If your CPU is really hitting 99.5°C, that’s a major concern! It likely means your CPU is hitting its thermal limits and might be throttling itself to avoid damage. You should consider getting a new cooler—definitely try to confirm those temps with HWInfo first, though.
An older AIO cooler, especially one that came with a prebuilt PC, might not last too long. If you're using old thermal paste, that can really contribute to higher temperatures as well. Making sure everything is clean and maybe repasting can help, but if the cooling is still not adequate, a new cooler could be the way to go.
Have you checked how your AIO fans are performing? It could be that they're not cooling as effectively as they should be. If they're running at max RPM without any odd sounds, it might just be that the cooler is aging and could use a replacement.
