Would It Be An Issue?

Am still planning on my future rig, decided to go with a high-end air cooler than an AiO.

Since I can't seem to find be quiet!'s Dark Rock Pro 2 anywhere in stock currently (online stores that ships internationally), I decided on Phantek's PH-TC14PE that will either go into Fractal Design's Arc Midi R2 or Define R4. The CPU cooler height clearance in both the cases are 170mm and the cooler's maximum height is 171mm, and now comes my main question and the purpose of this thread, is that 1mm negligible or will it cause any issues?

Usually there's a bit more space that it says, and define r4 has that foam thing inside too.

Well 1mm is kinda close. But mine is pretty tight too. Case clearance is 165mm, cooler is 163mm tall. There's literally 1mm between side panel and heatpipes.

Many answers. Much thanks. So thankful. Wow.

But in all seriousness, thanks for the help guys, and JAKEBAB for that picture.
