"System" process out of nowhere is using about 20-35Temp Spikes during afk (i7-7700k-H115i liq cooling)

I have noticed my temperature goes up to 65 degrees on idle except chrome wit a single PDF tab open. it doesn't always stay like that. my usual idle temps around 36degrees Celcius. whenever i hear my cooling speed up pressing windows key and closing down makes it go away. I am also having around 70-75 cpu temps during(Arma 3 - BO4)mostly any games.

i have oc'd my cpu to 4.6ghz around 1.215core voltage

PS: I had to drill my case on top to make my liquid cooling mounted on the top to have good airflow since i want to use my case's own rgb intake fans. I can provide images if needed

Thats normal for an 7700k that has not been delided.

The 7700k has temprature spike problems and people has reported about that problem since the CPU was new.

Solution: Live with it or delid and apply liquid metal.

okey thanks for the response dude im not encouraged to delid my cpu, i have also found out system( being Ntoskrnl.exe getting corrupted or virus might have embedded ) causing the afk temp problems since anything i do move a mouse cause "system" to turn to be "system interrupted" and finishes the cpu usage .
