Noctua's Upcoming Fanless Passive CPU Cooler Pictured

Noctua revealed their prototype passive cooler at Computex 2019 it weighed in at 1.5 kg and could dissipate 120 W passively or 180 W with quiet case fans. The prototype included mounting for both AM4 and LGA 115x sockets with the cooler able to keep an Intel i9-9900K cool under load. Noctua has been working towards releasing a commercial passive cooler in Q1 2021. This new cooler has recently been pictured by @FanlessTech and is reportedly about to enter mass production. Noctua is likely to announce more information about this new cooler in the coming months.

interesting. maybe fan less will finally become common in a year or two, or three.

Very nice. The 5 5600X's TDP is only 65W, so this cooler should handle it, even under heavy load.

Next they will have to release a wider Case to fit this oversized Cooler in.

Been waiting 2.5 years for a new NH-U14S cooler first teased at Computex 2018...

oh 1.5 kilo, feels like you just put a slab of aluminum on the processor

They could try making a passive or low rpm fan case at this point, there is a niche for htpcs and not many players.

Wtf is that roadmap? Months just to coat NF-A12x25 in black. Then another months just to swap the color from black to white.

Nice to see the desk fan is still coming!

They're getting pretty good at hooded sweatshirts, though.

I'd say it's iffy outside of the NUC or extra small form factor PCs; even past attempts at passive cooling didn't become common, especially as tech began to run hotter (GPUs especially). That said, builds where the cases themselves are the heatsink has had some success cooling hot components. Linus even covered a special order that used a TR or EPYC and a high-end GPU. But those kinds of cases are still niche.

You ever worked with plastic injection moulding? Based on your comment, I'd say no.
They're using some special plastic in their fans that apparently caused some issues when moving to black for starters.
You can't use the same mould for black and white plastic, as there will be specs of black in the white if you do that and it'll most like take a few thousand runs of the mould to get rid of that, so not a finally viable option.
Making a good quality mould takes 3-6 months depending on how complex it is.
So yeah, it's not "just" as you suggest.

Definitely not as easy as a few months work, but the NF-A12x25 has been out for around 2.5 years.

Here's the prototype. Doesn't seem they changed much.

They're letting the paint/coat dry, come on that obviously takes time :laugh:

According to that roadmap, not only does the NH-U12A needs covers for some reason, I was actually intrigued as I noticed Noctua actually did not make a fan controller, despite making all sorts of adapters. Looking forward to that, too. :)

That just looks like a vintage radiator, gosh! :(
NOFAN come back, exist again! People need you now!!

I see lower minimum rpm in smaller fans. I think would be ideal for a cooler like this, something around 75-150rpm.

That's the small version: do you have a pic of the standard version?

My god that is big, but looks perfect to attach a 140mm fan on the top and bottom though the bottom one would be a tighter fit and might need a slim profile fan. If it cools 180w with just a a low RPM two reasonable RPM fans the way I described ought to cool quite a bit more.

Eh, it's not solving much.

Truly fanless in big cases is not really needed, when you can just slap a few high quality low RPM fans, which are essentially inaudible at 500-600 RPM or so, and make cooling that much better anyways.

Not just that fan controllers can do the 0db depending on the temps and it's becoming a lot easier to do well each generation. Fanless computers aren't difficult all these days it was trivial enough for C2Q era of parts and tech matured in many area's.

Fans on a heatsink like that give less of an effect than you seem to expect. This is likely to work optimally with airflow from a case fan or two and adding fans to the heatsink itself will not give much more cooling capability.

Wonder what the price will be. And hopefully it will be cool :laugh:

I really hope that fan hub is not dumb 1 signal multiplier.
