Noctua Introduces NH-L9i Low-profile CPU Coolers for LGA1700 and NA-FD1 Fan Duct

[freeagent]

Does anyone know of any other coolers that came with a duct other than Thermalright? It’s a good idea that should be used more.

lol, how can this thing can possible cool a 300 watts cpu. This can only be a joke.

Not hard to use them, you just set your i7-12700k to 4.5ghz all core, and lower the voltage. You'll only need 120W at max power draw.

How can a single thread attract so many cranks who doesn't even bother to fact check on Google before coining up obvious things.

Yeah I know. Intel uses little power if you keep it 4.5ghz or lower. If you tune your CPU voltage you can drop very low. 4.5ghz is 112w. i7-12700k. And while gaming etc. you'll never get close. As long as the motherboard has a good BIOS (a lot are not great) you can also just set any power limit you choose and get the full 5.1ghz turbo under 100w, also for gaming.

Now they also need to make a duct for the NH-C14S ^^

It would need to be a bit different as that has the fan clipped on rather than screwed in, but it shouldn't be hard to do - just make the mounting mechanism a thumbscrew that threads into the fan itself, rather than goes through it and into the cooler. IMO, they should just make this mounting mechanism, then launch similar "universal" kits for 92mm, 120mm and 140mm.

Actually got a reply from Noctua on one of their videos.

"We're seeing hardly any benefit with larger, taller coolers."

"It's not so much about the fan thickness (L9 with 25mm would benefit as well) but about the fact that with larger coolers like the C14S, there's usually less hot air accumulating around the cooler due to the fact that there's space underneath."

So it's all about the clearance underneat the cooler.

That makes sense to some degree - the L9x series does sit almost flush with the motherboard, so there isn't much space for air to escape - and escaping air will be turbulent and slow-moving, which likely promotes recirculation rather than it being ejected away from the cooler. Still, I'm surprised they aren't seeing any benefit at all, and it makes me wonder about the use cases and case airflow - the problem of an "intake" fan mounted more than a few mm from the panel still applies, after all. But I guess most cases that can fit an L12S or C14S also generally have better airflow characteristics. Still, I've seen people have very good results with ducting coolers like that in mid-size SFF cases.

Oh, btw, it's not announced anywhere, but they have a mounting kit for the FD1 for 25mm fans that you can get for free if you contact customer support.

I think the C14S works best in a SFF when used as configured out of the box, with the fan blowing away from the motherboard.

I used the C14S for a short while in my Define 7, and when swapped the rear fan into intake (filtered) it dropped temps by atleast 5C. My full fan configuration then was 2x Front Intake, 3x Top Exhaust and 1x Rear Intake. All fans were NF-S12A.

Why can't you accept the fact alder lake is a fail

Old comment, but have you forgotten about 11th gen? Alder Lake is the biggest improvement Intel's had in a decade.

True, alder lake was the break from 14++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ hehe

Implying gate sizes are the exact same as the advertised nanometers.
