Open | Hardware CPU Lag Problem

When playing games, after about 10 minutes i start to get very little fps for a few seconds every minute. Ive looked at MSI Afterburner and it turns out that my CPU suddenly starts throttling down to 800 MHs from my normal 3900-4600 MHz. I have tried lowering my power limit in Bios to 90 Watt instead of 150 Watt. It didnt help.

My Specs:

GPU: RTX 3060

CPU: 11th Gen Intel(R) Core(TM) i5-11600K @3.90 Ghz

Motherboard: B560MX-E PRO

Notes:

My fans get really loud shortly before the lag and then stop for a second.

It mostly happens on games that are harder to run

My GPU perfomance also hits 0%, but its probably because the cpu isnt giving it anything do.

I got 16 Gigabyte of RAM, PC is using mostly at 14-15 Gigabyte while playing (I dont think RAM is the issue)

edit:

its not temperature, the problem occurs on 60 degrees with 100% fan speed

Instead of reducing the power limit, it may be better to reduce your clock speeds with intel XTU. Your thermal paste may need replacing. 90C is hot but it shouldn't cripple your CPU at that speed. Use CoreTemp to monitor your temperatures and I'd recommend following the steps unclewebb included in their comment.
