Problem with the GPU and CPU Load while gaming

[Hessoide]

To begin with here are my components:
CPU; AMD FX-8370
GPU; GTX 1060 3g
MOTHERBOARD: ASUS M5197 LE R2.0
RAM: 16 GB
SSD: Samsung 850 EVO
Power Suply: 750w
Windows 10 Pro 64-bit

When running any game, all starts perfect, 60+ FPS, no problem, there is none drop of FPS, but in certain time, could be 5/10/15 minutes i have a strong drop of FPS. It goes from 60+ to 20 or 30 and it is really anoying.

I have been monitoring the Loads of the GPU and CPU and his temps and i could see that when I have 60+ FPS the load of mi GPU is higher than the load of the CPU, which is normal. But when i have this rare drop of FPS the GPU loads go to 30%/20% or less and the load of the CPU goes to 90%/100%.
It only last a few seconds, but it makes me rage a lot.
There is any way I could fix this? It happens in almost every game
The temps are right, do not rise so much, like 60 C.
Sorry for my english 😛

Take side panel off and aim a fan at the capacitors nearest the CPU, see if that makes it go away. I suspect the vrms on your motherboard are overheating and making your CPU slow down to keep from melting, this slow down in clock speed makes it reach 100% usage and stutters until vrms cool off, then it repeats

The cheaper ASUS motherboards tend to have poor VRM cooling. The best way to handle it is to make sure you have a good blow down cooler. AMDs own stock Wraith cooler actually does a very good job at this. It runs quite and it blows a lot of air down to the VRM. If it is an issue with VRM heating, this should help. Depending on your sensors, your VRM could be getting hot but won't show your CPU as getting too hot.

It works rights!!, thanks , but that means that i need a new motherboard? In that case, which one do you recomend?

Just for the sake of making it easier as the list is kind of long. Any 990fx board should suffice

This is what I have for my 8350. The VRM cools nicely on it and it won't break the bank.
