There are so many variables with cooler fit.
How tall is your RAM?
Does your mobo have a chip cooler behind CPU and if so how tall it it?
What fans does cooler use?
How long is cooler.. will fans be over RAM?
What is case clearance?
Fans + RAM or chip cooler height = one height requirement
Cooler = another
Personally I will believe & trust what I actually see and measure rather than manufacturer's specs.
Measure twice to be sure and than again.
Example is Phanteks in my R2/R3
Or Thermalright saying TY-140 is 160x140x26.5mm when it's really
151x141x26.1mm 151mm NOT 160mm!!
My mobo chip cooler spec is 40mm and fan on it is 140mm and it fits no problem. My case spec is 165mm. That's 15mm!

But it fits.
I only make suggestions and offer information. In the end you have to decide what to do.
