Hi guys,
I am building my first pc and I have a Noctua NH-L12S, an Asus Rog Strix z370-I motherboard and a Cooler Master 110 case. I can't place the Noctua in low profile mode because it interferes with the ram on the motherboard. I will have to put the fan above the fins. The thing is that I see in most videos that when they put it above, they also change the orientation of the fan (air going down to the motherboard). Why is that? I don't understand.
