https://pcpartpicker.com/list/X49WgL so hello, I am looking to buy this awesome amd gaming/streaming/editing build. But not sure about how the cooling performance will go, I wanna make sure it doesn't overheat or crash simultaneously. I might overclock to about 4.1 ghz roughly while gaming, so will case fans 100% needed for this build? Keep in mind I am not using a 7700K 4.8 ghz overclocking.
