4U Case With Threadripper 3970X - Air Cooling Possible?

I'm researching doing a rackmount build with a 3970X a Asus ROG Zenith II Extreme and two PNY 2080TI Blower Edition GPUs. I'm a little worried about a CPU cooler + I have a couple general cooling questions. 

 

I should say up front, that the machine will be going in temp controlled machine room and noise is not an issue - this build is for creative work in Resolve, Premiere Pro etc not gaming. 

 

I'd likely go with this Rosewill case because I've used it before and like it. It has 2 120mm intake fans, and 3 additional 120mm fans in the middle of the case However, I'm not a big fan of the Rosewill case fans (I've had a few die on me). So I'd replace them with 120mm Noctua's.  

 

So my first set of questions are:  If noise is not an issue would you stick with retail Noctua 120mm or step up to the 3000RMP industrial ones? Or do a combo like the 3000rpm fans for the two front intake fans and the slower retail fans for the middle fan array?  Or are the 3000rpm ones in general just overkill?  Same question for the rear 80mm exhaust fans?  

 

Next, In my previous build with this case I used a Xeon E5 2697 v3 (14 core at 2.6ghz). I have a Noctua 92mm NH-U9s with fans on both sides. It works well and more to the point fits the 4U case without issue.  However I'm worried that the sTRX4 version of that same cooler might not be enough for the Threadripper 3970X?  It seems like I might have clearance in the case to step up to the 120mm version (which is 158mm) but I'm not totally sure. 4u is 177.8mm but that's the outside dimensions. Obviously the motherboard sits a bit higher off the bottom of the case, and the processor itself adds an additional few MM.  So I'm not sure if a 120mm cooler would actually fit?

 

I've considered an AIO like the NZXT Kracken X62 or X72 but I'd need to modify the top of the case to make this happen (can do as I have access to a machine shop) but it'd make opening the case a PIA plus I'm worried about water in a rack with other components below.  

 

Finally, I know a quick response might be use a different case or why do you have to rackmount, unfortunately that's really not an option.  It has to be a rackmount case.  

 

Any advice is appreciated!
