North Ram clearance with top 240 AiO

Hello all, I just wanted to get confirmation because the official specs mention only 35mm Ram height if using top AiO, but I’ve seen many builds on yt that use top AiO and Rams like G.skill Trident Z5 or Corsair Vengeance, which are 44mm height.
My Ram of choice is the Klevv Cras V rgb, which is also 44mm height, so I was wondering if there’s a trick to make them fit, or the 35mm on the North spec sheet is more of a conservative limit than a strict one?
Also with that Ram I have, what top AiO do you recommend to cool a 9850X3D that’ll be powerful and also fit without issues?
I’m not a fan of front AiO mainly for aesthetics but also GPU temps.
