That's a very cool hack, but there are tons of things on a system that aren't the CPU that would benefit from some moving air. A fan somewhere in the system that just moves a bit of air would, I think, really contribute to the overall longevity.

This isn't a problem. The article says that this is only if you're looking to trade-off performance for less noise:
> In other words, we would only recommend upgrading to the NF-A12x25 G2 if you seek to lower noise levels as much as possible and if you are willing to sacrifice the maximum performance headroom in worst-case scenarios that the G1 HS-PWM fan provides.

That's for switching to the NF-A12x25 G2 fan (from the G1), which has a lower max RPM. The improved side panel appears to be a strict improvement.

I would really be interested in desktop if so many items weren't non-upgradable. It's bad enough the CPU and GPU, but understandable, cannot be upgraded, you're stuck with the selected memory at purchase too. Even the laptops have up-gradable memory and that's typically where you would see memory soldered to the board.
daemonologist 16 minutes ago [-]
I agree, but here's a quote from the CEO explaining (to some degree) the choice:
“So we did actually ask AMD about this the first time they told us about Strix Halo. It was literally our first question: ‘How do we get modular memory? We are Framework after all.’ And they didn’t say no actually, they did assign one of their technical architects to really really go deep on this—they ran simulations, they ran studies, and they just determined it’s not possible with Strix Halo to do LPCAMM. The signal integrity doesn’t work out because of how that memory’s fanning out over the 256-bit bus.”
If they made the memory upgradable it would defeat the purpose of the machine, since memory modules can’t hit the same speed as soldered memory.
If you’re buying this you’re probably maxing out the memory to start with. 128GB is borderline barely adequate for local LLMs.
Dylan16807 2 hours ago [-]
You can get DIMMs that do 8000 right now, and LPCAMM2 should become capable of even higher speeds even though it's "only" 7500 at the moment.
Framework says in their blog post that they talked to AMD about using LPCAMM2 and the engineers "finally concluded that it was in fact not possible without massively downclocking the memory". And okay, I believe them, but I'm pointing my blame a lot closer to the CPU than the memory modules.

The other difference with AMD's AI Max is that it's using a 256-bit bus compared to LPCAMM2's 128-bit bus.

Right, you'd put in two of them.
Half your data lines run to each module, and you can put them both tight against the socket, so no routing issues there.
If there's a control line that would need to be shared across both modules, and it can't be shared in a fast way, or there's some weird pin arrangement that causes problems... oh look I'm back to blaming the CPU.

I don't understand how many parts people really upgrade these days.
For one, the memory is soldered on because it's integral to the GPU the same way it's integral to the Apple's M3, and can be used the same up to 96gb.
At the form factor, what else are you expecting to upgrade over it's lifetime?
This statement makes it sound like there's a lot to upgrade when it's mostly just memory people seem confused about.

I think you're using your 2000's brain and not updating your firmware to the modern consumer appliance. We're watching computer tech growth decline sharply with fewer leaps and bounds.

That makes it more surprising. It's not that desktops went off in a different direction. Desktops are moving closer to their area of expertise and yet they are unable to apply that expertise.

So just use Noctua fans? That'd do it.
evanjrowley 5 hours ago [-]
It's more than just the Noctua fan. The fan grille is a contributing factor to noise [0]. The new design features in the article could reduce the noise of any 120mm fan.
Well the fan in the Framework desktop is some kind of purpose built high performance Noctua fan that is significantly louder than usual. So they are suggesting to use the new grill with the fan that comes with it so you don't encounter throttling.

Its been a while since I looked into "just use Noctua" for $another_use_case, but ...
Isn't the problem with Noctua (and similar "silent" fans) that they don't offer the same airflow throughput as their noise making bretheren ?
So sometimes its not as easy as "just use Noctua" ?
hnuser123456 4 hours ago [-]
Noctua makes 2000rpm and 3000rpm max variants of the NF-F12. Otherwise, through (over)engineered geometry and materials, their fans usually do push the most air volume and pressure at a given volume level, with a more pleasant sound profile. But you pay for it.

Worth noting that you are also paying for the service.

I think noctua fans are just better fans, noisewise.
They have better airflow design and sound dampening/isolating screw mounts.
I think the idea about reduced airflow might be backwards - most systems use PWM to spin the fans based on CPU or system temperature. This means the systems get the airflow they need.
Also, they make larger heatsinks + fans for certain systems that allow the same airflow using a larger, slower spinning fan. which means less sound.
that said, there are some noctua fans that can spin faster than others.

Noctua fans are quieter than most for a given airflow level.
They have a range of fan speeds going up to very high speeds.
Many people doing modifications will substitute a lower airflow fan for even more noise reduction, which might be why you’re thinking they flow less. That’s a function of fan choice, though.
Noctua fans perform very well on a noise-adjusted basis.

For some applications such as cooling of an extruder for a 3D printer Noctua fans indeed don't offer sufficient airflow.
But I don't think that's an issue for computer cooling unless you're talking about extreme circumstances.
