hello Lads i come to you with a question
So i am planning to upgrade my pc got new mobo+cpu to put inside(free so cant complain)
but the fan wont do since ive got only 70mm gap between mobo and case.

I am interested in getting Noctua NH-L9a-AM5
>https://noctua.at/en/nh-l9a-am5/specification
because of its low profile but im worried, wont the low profile and wide fan intervene with RAM sticks?
Other option ive got is Noctua NH-L9x65
>https://noctua.at/en/nh-l9x65/specification
I shouldnt have issues with interference with RAM but it only leaves 5mm gap, is this enough. My current setup leaves 10mm gap.

Which option of the 2 is preferable

Guts I wanna put inside
>Gigabyte B450 Gaming X
>AMD Ryzen 7 3700X
Current stuff I run
>Intel I7 6700
>Some proprioretary dell mobo
