PC starts to jerk after a while despite good hardware?

Hi, my PC starts to stutter after spending several hours on it. Whether it is in the game or editing video editing etc. Can barely use. Even when he just stands idle he also starts to spin after a while. Even if I play a game e.g. Fortnite begins, it jerks the first minutes as if he needs to get warm. Then I can gamble until it starts to jerk again. Latest drivers on it.

INTEL Core i7 8700 3.20 GHz

2x GPU RTX 2080 8GB (Not in SLI)

2x 16GB RAM

Mainboard ► MB Gigabyte Z370 D3 (Z370, S1151, ATX, DDR4)
Temperatures are currently at 40 ° C-45 ° C but is crazy.

I thought, maybe because it has 2 GPUs in it, but there are many others also have 2 built for 3D animation render and they do not have such problems. Do not know me at all.

Look in the Task Manager if you notice that it slows down when the load is normal then maybe change the power options, otherwise just watch which program draws the most power
