Question Potential CPU Bottlenecking

[Katernum]

I've had my PC for just over two years. Recently, whenever I'm in-game (Valorant specifically), I notice that if I have anything open, my game will severely drop frames whenever there's mouse input. I'm not sure if this is just because of age, or something might be wrong. I recently took the PC apart and changed the thermal paste, as well as blew all the dust out, but it started acting up after a week again. I know the system can handle more as I used to stream on the rig with no problems, but now even Youtube open on Firefox causes 60-70% FPS loss. Any ideas? CPU load usually doesn't exceed 60% during any of this happening.

CPU: Ryzen 5 3600X
Motherboard: MSI X470 Gaming Plus Max
GPU: EVGA RTX 3060
