Normal
I have the M1 and NR200 along with the NH-U12S, NH-U9S, FUMA 2, Black Ridge (and a couple of others I can't think of right now).I think the NH-U9S is a fantastic choice for the M1, and the U12S works really well in the NR200 but you can't use a glass side panel, or even the filter mesh on the metal vented panel. I belive the U12A is a better fit in this regard - from what I've seen online, but still no good for the glass panel.While the Fuma 2 is a good cooler for the NR200, I'd avoid it if your board has a large boxy heatsink enclosing the IO area, like the Asus Z390-i - it can cause problems fitting the cooler - I had to reverse it in my NR200, which wasn't ideal.
