 This video on air versus water cooling has 2 million views! It looks like crap! Time for an HD remake! And it's not just a pure sellout move to capitalize on an idea that we already know works, because a lot more has changed since that video than our production values around here. In particular, AMD's high performance, not to mention huge and hot, 180 watt Threadripper CPUs are pushing the limits of all types of cooling systems in ways that we haven't never seen before. So what's the ultimate cooler for the ultimate CPU? We have the answer. The white Dark Base Pro 900 from Be Quiet! features a modular design to support a variety of layouts and configurations. Check it out at the link below. We'll be testing six coolers that on previous platforms have delivered comparable results. Three air and three liquid. For water coolers, AMD helpfully provided an Asetek compatible TR4 mount in the CPU box, so we're able to use our existing stable of compatible Corsair H-Series AIOs, which is cool because that means so can you. We've got 120 millimeter, 240 millimeter, and 280 millimeter radiator versions, with all of them featuring the same Asetek design CPU block and in the H115i's case, a slightly more powerful pump. In a stroke of either luck or AMD foresight, the blocks are just big enough that even though the heat spreader sticks out, the heat producing die area for Threadripper is covered. So while these are mainly meant for more square CPUs, we have no reason to believe that you should worry about it. As for our air coolers, well, due to their wildly varying shapes and mounting mechanisms, not many of them have been retrofitted with support for socket TR4 yet, which is where Noctua's new lineup comes in. They're visually and for the most part, functionally identical to their non-TR4 cousins, but when you turn them over, you are immediately greeted with plates big and shiny enough to host a fancy dinner party. This huge mount is common on each of them, right down to the 92 millimeter NH-U9, because Noctua decided to bake in support for AMD's on socket mounting points. A good idea, because, well, let's just say that taking this apart isn't a good idea. Now to testing. While our old standard-def version of this video discussed performance with different custom fan configurations inside a case, our video today will focus on the temperature differences between the coolers themselves right out of the box. So it should then be noted that you could get slightly better performance out of these AIO's by adding more fans in a push-pull configuration, and the same can be said of the two tower coolers. Another trick up our sleeve this time around is that we're going to be running our Threadripper 1950X in both stock and overclocked configurations. Furthermore, this time we are in a climate-controlled 24 degrees Celsius environment, not my garage during the winter, so our results should be more comparable to what you can achieve at home. But enough talk, let's do the results! Starting off then with our H80IGT and Noctua NH-U9, we're seeing some pretty okay numbers for stock performance, with similar load temperatures and package power. Overclocked, on the other hand, shows again similar numbers, but markedly lower package power for the H80IGT, meaning that it's throttling more to maintain that same 87 degrees. So in the lightweight category, air cooling comes away with a clear victory. The next step up is the NH-U12S and H100i V2, and again we see almost identical numbers between these guys at stock speeds. Looking now at the overclocking results, we've got a much narrower lead for the Noctua fan over the Corsair AIO, as far as package power goes, meaning that they've throttled just about evenly. So we're going to call this one a tie. Bringing us to the main event, the NH-U14S weather versus the H150i Braggr. Both of them lasted all 12 rounds, maintaining maximum performance in both the stock and overclocked tests, and this is incredible considering we've got all 16 cores pinned to 3.9 GHz, but this kind of a match isn't about pinning, and the Noctua ran a few degrees cooler, so we have to award it the win by technical knockout. Of course, performance is only part of the equation. Aesthetics and physical compatibility are key considerations as well. Water coolers do come with an additional mechanical point of failure, the pump, but they look sexy and it's becoming more and more common for small form factor cases to have mounts for 120 or 240mm radiators, but not enough clearance for comparable air coolers. And it's also worth considering that large AIO coolers like the H150i are generally far easier to work around inside a chassis than a larger air cooler, especially where RAM slots are concerned. With that said, price is kind of a big deal too, and Noctua's solutions, even though they're not the cheapest air coolers out there, generally come out ahead of the water cooling equivalents by a significant margin here. So TLDR then, if you're not planning on overclocking Threadripper, it's actually a relatively easy beast to tame, but overclock it and you'll need to set aside some budget for a beefy cooler. Also, if your priority is performance, you'll reach for an air cooler or custom water cooling, but water cooling is a great choice if a more compact, easy to work in and subjectively better looking machine is what you're after. So then, as always, the answer is... It depends. If you haven't already, now's the time to try out Dollar Shave Club. It's more than just razors!
