Question Low performance with good PC all of a sudden

These are my PC specs :

GPU - NVIDIA GeForce GTX 1060 6GB
CPU – Ryzen 5 2600X
CPU Cooler - AMD Wraith Spire
Motherboard – Gigabyte X470 AORUS ULTRA GAMING
RAM – Corsair Vengeance 2x8GB 3000 MHz
OS - Windows 10 Pro (version 1909, build 18363.592)

I am getting low fps in games like CS GO and PUBG since a week, I used to get 250 to 300 fps in CS GO and 80 to 120 fps in PUBG but now I get 60 to 90 fps in CS GO and 10 to 60 fps in PUBG. I monitored the CPU, GPU temperatures and other info when pc was idle and when I was playing a game (10 minutes each) and this is what I saw:

When idle the CPU temp is around 60 celsius, GPU temp is around 42 celsius, CPU usage is 0 to 20%. When I am playing PUBG the GPU temp is 58-69 celsius, GPU usage is around 90 to 100%, VRAM usage is 1088-2589 MB, GPU fan speed is 58-69%, CPU temp is 67-81 celsius. CPU usage started at 17%, went as high as 56%, then dropped down to around 10-15% and held there for a long time. RAM usage was 5926-9241 MB. FPS started at 90, went as high as 167, then dropped down to around 10 and held there for a long time. Is the CPU temp too high when idle? Why is the CPU usage so low? I don't know what exactly the issue is.
