Nice! Is 86C acceptable for the 3970x underload? The AMD website has me a bit nervous as right on the specs for the chip they say 68C Max temp. Are you experiencing throttling at 86C?

Thanks really nice! Gotcha - I can probably live with that as long its not like bending the motherboard I do think the one issue I might run into is fan headers on the motherboard. According to the motherboard manual there are 6x 1A 12W fan headers (plus 2x 3A 36W Pump headers). But I guess I could get a fan hub or fan controller for the 2x 120mm intake fans and the 3x 120mm Middle case fans.

Thank you!

Great info thanks! No don't have to do this all at once. I can def. take some time to experiment. I've been looking at the NH-U12S TR4-SP3. Which looks to be the same height dimensions as the U12A but with only a single 120mm fan. Do you think I could just pop another 120mm fan on the U12S? Did the U12A fit in your 4U Rosewill? I totally understand this uncharted territory!

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!

Super helpful! Thank you @TVwazhere This is the case I’ve been considering https://www.rosewill.com/product/rsv-4310l-4u-rackmount-with-7-cooling-fans-10-internal-bays/ Not sure if you have a opinion just from looking at the link, but I really appreciate the guidance.

yes of course that's an option - I just like the feature set of that motheboard for my needs

I’m looking for a rackmount case that can accommodate an XL-ATX motherboard like the Gigabyte Aorus Xtreme. Does such a thing exist? I can find a ton of E-ATX but not XL-ATX. As this build is going in in a climate controlled machine room with racks I’d like to avoid a full size tower or one of those cube cases - I’d like to put the box in a rack. 4u is ideal but could deal with 6U.
