Noctua is making Ampere Altra coolers

“The new Noctua NH-D9 AMP-4926 4U and NH-U14S AMP-4926 are the last pieces needed to make Ampere Altra Arm development desktops and desktop servers viable” - Patrick Kennedy of ServeTheHome

Can confirm, the Noctua NH-D9 AMP-4926 4U fits nicely inside a 4U case, runs extremely quiet, and keeps the chip cool.

I’m building out a 45Homelab HL15 server with this cooler, and compared to this little guy, the NH-U14S looks comically large :smiley:

Honestly to me, it looks like something out of steam punk. :slight_smile:

The steampunk look adds to its desirability. :heart_eyes:

I recently got one of the 92mm ones and it works very nicely, just like Jeff said.

For B2B customers only. How many did you need to buy to qualify?

They are, but they are not if you ask them nicely.

I’ve sent an email to them, basically next business day got a reply saying that they are ok to sell one cooler to a private person if I’m ok to wait a bit and pay basically retail price.

Though I haven’t got mine yet, but probably it would arrive in next few weeks.

I only had to buy one. As Civiloid said, I asked nicely. Ok, I may have slightly begged them with a sob story of my electrical taped 2U cooling sink. They were excellent to deal with. Price wasn’t bad considering it’s a low production run. They are still feeling out the demand for it.

dumb question these, what is the temp with just the box open vs. a ‘normal’ fan vs. one of these?

Noctua Ampere Altra coolers are now click to buy Noctua Ampere Altra cooler | Newegg.com The jumbo XXL NH-U14S makes the Altra M128-30 CPU ~10°C cooler than NH-D9 which is also a great cooler, but its big brother is glorious ultra quiet overkill. Thanks for your patience!


@Aaron I think the the delta between open box with 2U passive and the NH-U14S is in the neighborhood of 30°C with 64 core and even more with 128 core. But nothing compares to @bexcran’s latest cray cray water cooled build running Altra at 35°C🥶 which is colder than outside my house right now.

JoeSpeed is about right. The 2U cooler without fans would creep my Q64-22 up to about it’s thermal limit, I had to put 2 40mm fans on it to keep it around 60ish degrees. I didn’t work it hard to avoid the high temp. The noctua 92mm knocks it down to about 38ish at idle and keeps it low without hardly any fan noise. Compiling Vulkan shaders uses all the cpu, and this thing keeps it coo. It’s a huge difference.

Ok, I may have slightly begged them with a sob story of my electrical taped 2U cooling sink.

I’ve literally said to them, that I recently got that board, wanted to get a better cooler but noticed that Noctua is only available for b2b and asked if I can buy one directly or I should wait for the availability in retail and if so - when I can expect that. Nothing special, just politely asked.

And while I’m waiting, I just screwed in a single 40mm fan to my 2U cooler and that is rather loud, but do its job (about 75-80 C under load, while being loud).

Main reason why I went for D14 is hope that it will be inaudiable :slight_smile:

Price wasn’t bad considering it’s a low production run.

Price was exactly the same as for similar cooler for another server platform (I have LGA4677 as well and got Noctua there).

The 92mm one is very quiet, I don’t really notice it even with the case side off. That D14 should be pretty quiet, even under load on the 128. It’s wonderful that they are selling them retail on newegg. I’m excited for you, the D14 will be glorious!

Oh wow, an EU company is selling their stuff exclusively through a US retail store that does not ship to the EU.

Not exclusively, you can get them directly from noctua, which is what I did. I am pretty sure EU customers can do the same.

I had also asked the b2b channel at Noctua, hoping they could point me to one of their customers from whom I could order. They offered to sell me one directly (to USA), which was very nice of them. They only accept wire or ACH transfers for payment, which I was not interested in doing. I was going to do a water cooled setup but the news that Noctua started selling these coolers through Newegg prompted me to order through them. The total cost with shipping seems comparable to the direct b2b quote I received in case anyone is wondering.

I got mine delivered yesterday. On a Q64-22, temperature dropped from ~60C in idle to 31-32C IDLE, and under load (HPLinpack) I saw 42C tops (was 80+ before). Fan curve was default and I think it needs to be adjusted (not as quiet as it could be, as I don’t really need to keep my CPU under 50 all the time and even at idle).

Noctua b2b at least in Europe offered me to pay by card though, so no transfers or anything.
