Ok so my AMD 8350 has been acting weird. When ever i play any game CS GO to GTA V the CPU will randomly go from 40% usage to 17% causing sound to go all staticy and the frames will drop to 30 or 20. Its very..very annoying. Yes the CPU is overclocked but i have ran it without the OC for about a week with nothing. The temperatures are fine nothing to alarming. Someone give me some answer please.
SPECS-
AMD 8350
120mm Rad with some Noctua fans
GTX 970
16gb of Adata ram
Gigabyte 970a-d3p motherboard (this could also be the problem im not sure)

There are fans made specially for this purpose (cooling VRMs) or you could replace the CPU cooler with a larger down-draft cooler that would cool the VRMs as well.

If the motherboard VRMs fail, it is VERY unlikely to damage anything, so I'd ride the horse until it dies, THEN see where you are. Maybe a Zen system will be a better alternative then.

Is it a new system or has it only recently started acting this way?

You certainly have a problem with that motherboard. It is not suitable to overclock a FX 83xx at all and, although it will run a FX 83xx in office or home applications, I would not use that motherboard, even at stock speeds, to run high-performance applications like gaming. The power delivery system can overheat and throttle your CPU. To test if this is a problem, move or get a case fan and zip tie it so it blows directly on the power delivery components of the motherboard, the parts between the CPU socket and the rear I/O shield, and see if this helps.

I'd like to know what was wrong first, in case it is something else important as well. Temporarily putting a fan in to blow on the VRMs will confirm that motherboard upgrade is the right thing to do, before you spend the money.

That's a cool motherboard with great new features, but I'd wait a bit to see how it's power works out. It OUGHT to be great, if it has eight true power phases (as opposed to four phases doubled) and it has good heatsinks on the VRMs. I KNOW the Gigabyte 970A-UD3 or UD3P will work or the ASUS M5A97-PRO.

OK SO, it is the VRM and power dilivery on the mobo. I put a fan infront of the two heatsinks and played some GTA V and it was perfect 76fps constant. I took the fan away and there it whent pulling the cpu usage down and in turn lagging the game. So the question is do i just get some tiny fans to put over the two heatsinks (idk how thats going to work with the radiator so close to them) or do i jist Get another mobo?
