Noctua might have had a small booth showing off its products at Computex, but it had plenty to show for itself. On the booth was a new and conceptual design with a large aluminum tower heat sink weighing around 1.5 kg. This means processors drawing up to 120 W can be used while eliminating noise levels to zero.

Well known for its high-end air CPU cooling solutions and unique color theme, Noctua has designed a completely fanless CPU cooler with the capacity to handle CPU loads of up to 120 W. After speaking to Noctua about this concept design, they stated that the 120 W is guaranteed with this design providing the chassis has adequate convection, and plenty of breathing room. In tighter environments, the concept can stretch to 180 W with quiet chassis fans, or a fan directly placed onto the cooler. The bulk is made up of aluminum, with an asymmetrical design designed for better PCIe slot clearance, as well as being compatible with memorty on both Intel's LGA115X and AMD's AM4 chipsets.

On the booth was a test system demonstrating the concept, which currently has no name, while it was cooling an Intel Core i9-9900K on an ASUS Prime Z390-A motherboard running Prime95, inside a Jonsbo UM4 chassis. While the temperatures weren't exactly helped on by a warm Taiwanese climate, the Noctua fanless averaged a CPU core temperature of around 94 °C under a full Prime 95 load running all day. That's quite impressive given the Core i9-9900K is a premium processor, although the high temperature did thermally throttle the processor down.

While the Noctua Fanless CPU cooler is still completely conceptual, it's due to be completed and released some time in 2020.

    Price. It might be patented, but they can't patent a heatsink, which is what the case panels are if you boil it down. Give your panels some surface area, add heatpipes to get them warm, it'll work. HDPlex and Streacom both make good passive cases, but they do hobble themselves a bit by using only the short sides as heatsinks. Of course, the Airtop also uses a custom motherboard and GPU mount, which makes it easier for them to implement.

    Wow great concept! Nobody has ever thought of it before - a chunky 20 pounds heatsink hanging on your motherboard.

    You need to work on your metric-to-gibberish conversions.

    well it might be 94 degree celsius but slap a quality fan on it, undervolted so it spins at ~300rpm, and you get a nice 60-70 degree celsius.

    do the same for the gpu

    and the psu can totally get by being 100% passive, just get a nice platinum one which is very efficient.

    and I can guarantee you you won't hear it, not even in a silent/quiet anechoic studio chamber.

    (ofc, quality components so no click-clack nor electronic noises etc)

    yeah, any wind power and the thing cools down so fast and a lot, totally passive is overkill.

    This would probably work best in conjunction with a case designed for convection cooling. Are there any such cases publicly available?

    The other part of the puzzle is GPU cooling... I was surprised to see that Arctic apparently no longer sells their fanless GPU coolers, so options here are limited. And is Noctua also planning on releasing a fanless X570 chipset cooler? That 40mm fan is probably going to be louder than the rest of the system put together.

    If there was a way I would put that nf-f12 on the x570 chipset but for that to work flawless, a 12x12 heatsink is a must.

    Cooler Master ATCS (Active Thermal Convection System) 840, which IMO is still the best case the company ever made. No plastic, No glass, pure performance.

    And you can put a "53GHz" PC inside. :D

    Do you say Passive ??? Dual xeon L5630 32gb ecc... this chipset has 21w TDP, when summer hits i will put the xbox 360 heatsink "jasper"
