Slightly smaller then a Noctua D14 advice

[LupoLover]

Just got a Thetis case and I have 185mm from back plate to side of case (That includes mobo and stand offs)

My current setup with my D14 measure 185mm, so dont think its going to fit, however I will try.

What is the next best cooler I could get to fit ? (Its 1551 if that matters)

On the Noctua side you have the NH- U12S (which sits 2mm lower than the D14) or the NH-U9S which sits 35mm lower according to Noctua:

In both cases you'll be sacrificing some cooling performance though. Do you plan to overclock?

Its a 6600k so be rude not to. Changing for a 2mm saving I dont think would be worth it. This 212 cooler any good?
Really I should be checking tonight before worrying too much, but I like to plan.
