I have a hunch that I won the silicon lottery with it, though I haven't confirmed with any overclocking. I'm happy to dive deeper if you want. Below is a basic summary. I have 5x140mm intake fans, with a Noctua NH-U14S TR4-SP3 cooler. That runs with push-pull 140mm fans, 2000RPM in/1500RPM out. This reaches steady state within a few minutes under load. With an open case, it will clock down to ~4.2GHz after 5-10 minutes. With a closed case, that is faster. For fun, I ducted the A/C vent in the room into the case and cranked it. It stayed reliably up around 4.4GHz all core. Technically, I think it would reach a lower steady state clock/higher temp if I left it for days, as it does noticeably warm the room. I don't recall idle power, but yeah, it's warm.

OK, that's really neat. I have almost the same setup except use 120mm fans on the NH-U14S (to clear the RAM, I populated all 8 slots ;) I am very tempted to switch to water cooling. Seems like I could make it a little quieter, and get a little bit more performance. $1000 more performance? Probably not. But it would be a fun project. (In general, I am blown away by the Threadripper's performance. I have C++ builds that took 15 minutes on my 6950X that now take 2!)

  My fans are offset ever so slightly to account for RAM clearance, as I, too, have eight sticks. I think we basically built the same computer with a couple different choices (; I lose millimeters of fan coverage (I have millimeters of fan peeking over the top of the tower), but I opted for this, since I get more airflow over the width of the cooler. The effect is probably measurable in single-digit percentage differences in a highly controlled test. The big thing for me was the case airflow. That thing throws off so much heat that my case ambient temperature was growing to be 10C or more above the room ambient. Hence the 5x140mm intakes. The back of that machine is a nice heater when I'm crunching anything big. My goal is to keep those fans, but attached to radiators. I think 5x140mm of radiator should give me much better heat transfer.
