everyone we're at the Noctua booth now at Computex 2019 and NOx was always got some pretty cool stuff at the show last year we gave them the award for the least amount of RGB shit at a booth and so we've returned and once again it looks like knocked Oh we'll be receiving that award because I've seen nary an LED while here so the things at the show that are of most interest to probably run into the passive cooler which I've got in front of me there's an NHD fifteen sort of I mean I don't want to say refresh cuz that downplays up but there's a new NHD 15 that's got that and that's the big cooler that's probably iconic and you likely recognize the a a series fan now in 140 millimeters has gotten some updates so we have a prototype on that to talk through and then there's just some cool testing setups behind me that I'll mention as well before that this video is brought to you by the gigabyte z3 90 ARS master motherboard which comes equipped with one of the more powerful z3 90 V RMS for heavier overclocks on the new 9th Gen Intel CPUs the ARS master is also one of the few motherboards with a really heatsink this generation featuring a mix of high surface area fins and looks oriented hover blocks oh and it's also got updated RDV illumination learn more at the link below let's start with the passive cooler so in front of me this passive cooler set up in the system next to me there are actually no fans in this right now in fact they've even gotten a bit cheeky with it and it says caution service may be hot because there's zero fans this can be set up obviously with a fan if you wanted to there's another test they did with a finit Wow that actually is genuinely pretty hot it is radiating quite a bit at the top but the cooler so there's no name for it yet it's just fan li's cooler right now we'll have a name later the target for release dates pretty far out so this is an early prototype and knocked was still doing a lot of tweaking on it but you'll notice in b-roll that the fins are actually spaced pretty far apart this is intentional when you don't have a fan with some sort of static pressure to force air through it through the fin stack that is you do end up with a worse scenario for passive cooling so what you want is a bit of space between each of the fins and the fin stack the fin density is lower and that's so that natural convection can take its course and you rely on just physics at that point so pretty simple rather than for we're seeing all the air through with a fan and doing it sort of semi manually so this one right now it's set up running about 120 watt load with a 9900 K and could run higher with a fan in the back so I think we heard about 180 watts with a fan just like a top mounted exhaust fan or something but 120 watt 99 100 K is really not bad for a passive cooling solution for the prototype in front of me this one has 1.5 millimeter thick aluminum fins so one aluminum because weight and heavy and you don't want to rip the socket out of the board and to that copper at some point doesn't really do a whole lot for you in in ways that are meaningful versus the price but there is still copper coal blades nickel plated copper heat pipes nickel plated those are centered and it is using a pretty widely spaced pin stack what might change is all of these specs so it's a prototype first half of 2020 means that anything I've just said is is subject to change based on naktu as in-house testing for example the fin thickness could end up coming down to something like 0.5 millimeters rather than 1.5 or you can make me go up to one it's really up in the air at present but one of the biggest issues is with the press so the manufacturing process the press that a lot of the companies use like we've seen in our factory tours recently there there there's big giant ones that weigh like 150 tons they come down and smash and stamp the fins and then sometimes they also contain a setup that can fold the fins into themselves to assemble the whole stack in an automated fashion so now I've to express stops at 0.5 millimeter thin thickness which means that going up to 1.5 millimeters poses a production challenge so Knox we're still trying to figure out what to do to overcome that because it's a multi-million dollar investment to just buy a press that can do 1.5 to 2 millimeter thin thickness those start well I mean yeah it's it's millions of dollars so they have to figure out our solution to that for example they could end up cutting out the automated automatic interlocking of the fins and go with a manual assembly approach that would do it but that's still all up in the air and I think that covers most it so the price target is totally TBD and Knox would like to see it below $100 but we're not gonna hold them to that until we see you know how they overcome the manufacturing difficulties for size it's about the same size as an HD 15 so it's a 165 millimeter tall cooler from the socket and then the rest is roughly the same as the D 15 I think that covers the passive one beyond the passive cooler which is just a cool tech demo I guess we'll talk with the NHD 15 updates next there's a couple and behind me but this one is the tr4 version which you can tell by looking at the cold plate so it's got the wider cold plate in previous testing when cr4 came out first gen we found with a 1950 X that increasing from a same color so like for like test everything identical just changing the cold plate size it did actually have a significant impact and that's because you've got a larger IHS and it's spreading the heat so I mean if you're not contacting the Hawaii chest you're kind of throwing away some of the benefit of having a larger IHS the differences for this one versus previously the fin density is the same fan pitch is the same heat pipes have gone up to seven from six so size is a bit different it's bit wider and then for the tr4 version the the spacing for PCIe was a obviously a major consideration so to make sure there's clearance for PCIe the heat pipes have been moved a little bit versus the standard models which you can see over there so it's an asymmetrical heat pipe layout instead of a symmetrical one it should be pretty clear on camera TBD on pricing maybe 20-ish more than the current units that are out there but don't hold them to that and then there's some production level improvements as well so improvements the heat pipe that weren't really specified they're still centered though and then I think there's a demo behind me running a tr4 system with the 2990 WX 32 core CPU it's at 440 watch all that really matters is the amount of heat that's generated not the frequency cuz it's the goal is cooling it so for the demo for 40 Watts it is still running so it's at about an 87 degree TDI right now and just running prime95 torturously on end and poor test conditions because I mean it's against a wall and Convention Center that's kind of warm so not bad but that's the TR force the cooler anywhere the energy 15 and I think the last there's a couple fans I'll just point out quickly will show b-roll of this is gonna be some white fans coming the black fans are getting finalized for the a series 120 millimeter cooler and then the black heat sinks that NOx was shown a few times now are getting finalized as well apparently there's some production challenges with cleaning the solder off the residue of the solder and then getting the powder coating on so that's being finalized still then this fan is the updated a sit well it's the 140 millimeter a series we talked about this at Computex last year one year ago and the difference is that when we talk to well the difference is everything in the fan but when we talk to Noctua they were saying well it's not really so easy as just scaling it up in CAD and then making a new fan so there's some markings on here that indicate that it's gone through a couple of revisions different changes things can change like how many blades you have the thickness of the blades the sweep of the blade where the blade starts to sweep down the hub how close the blade is to the outer side of it the design on the top of the blades lots lots and lots of things can change so that's in prototyping they're just kind of showing it off to tell you that it is eventually going to happen and Knox we could probably make it today but does want to push a bit more on the performance side to get a meaningful improvement so we'll keep you updated on when that happens I think that covers the Noctua booth thank you for watching as always you can subscribe for more writing at a store now cameras excess net to help us out directly and patreon.com/scishow sexist to help us out there as well I don't have any awards with me this time unfortunately cuz they're too heavy but if I had one I would give one to Noctua for still having the least amount of RGB shit at a booth I'll see you all next time
