Any one can tell me how to check to be sure for 100% is it software bug or hardware failure...When i play ARK survival (maybe on other game also, but havent tried) i have hard FPS drops, when i check graphs, i see memory drops.Also put GPU for stress...

Hi, can any one tell me why on ASUS ROG RX 580 O8G plugged external fans can be controlled, but not such as in product web site?I dont have option to control external fan by CPU t°, not GPU!
