I recently reapplied thermal paste (XTM70) on my Intel Core i7-13700K, and I'm still seeing temperatures soar to 97-100 degrees Celsius while playing games like WoW and BG3. I ensured the AIO cooler (CORSAIR H100i) is securely attached and that the paste is applied evenly, almost like butter. However, I spent $50 on new thermal paste because the last one didn't spread well at all. After this application, I'm letting it thermal cycle for a few days. Right now, it idles around 50 degrees, which feels a bit high, but it's during gaming that it really spikes. I'm hesitant to mess with undervolting since I'm worried it might cause issues. If things don't improve, I'm considering upgrading my AIO or case. Any tips would be greatly appreciated!

It sounds like it might be time to replace that AIO cooler, especially if it's around 8 years old. A newer option like a ThermalRight 360 could be a good investment and isn't too expensive! It sounds like your current setup might just not be cutting it anymore.
1. It’s possible the AIO pump has failed.
2. Check if your CPU is bent, which could be causing gaps and affecting contact. Either of those could lead to overheating issues you’re experiencing.
If you're still hitting high temps after reapplying the thermal paste, it probably means your cooler isn't functioning properly. Make sure to check if the CPU is drawing more power than it should—this can happen even during idle. It might help in diagnosing the overheating issue.
Honestly, if that AIO is as old as you say (like 7-8 years?), it's probably time for a change. Water coolers can lose efficiency with time as the liquid evaporates. Consider upgrading to a solid ThermalRight air cooler or a fresh water cooler to get better temps.
Is your AIO the 240mm version? Double-check that it's operating correctly, and ensure there’s no plastic left on the cooler block. Also, what are your temperatures like when the pump and fans are at full speed? That’ll give you more insight into the cooling performance.
If the AIO is vibrating, it seems like the pump is still at least doing something. But it could be worth investigating further to see if it's pumping effectively.
