I might be wrong but I never saw anything that it was gen5. I would test but my ada 2000 is gen 4.

Hello, fellow A2 users. Got my own A2 to use as main workstation. 9955HX, Kingston memory 5600@C40 with reflashed SPD.
The noise is awful. Disassembled, repasted, TJmax to 78, PBO -1000 - still noisy. May be because I have rather hot U.2 SSD (around 60C)
Ordered new larger case for better cooling.
I made small modification to increase space for rails. I can share STL if anybody need it. Should arrive in a couple of days along with fan and PWM controller.
Also bought a heatsink from Minisforum and sent it to the company which will try to make a custom waterblock.

If you limit temp to like 72c you will get 95% of the performance with less noise. You can also mess with the fan power limits to do this while keeping the temps in the 70s and noise low. I wish you could use ryzen master on these CPUs it would be so much easier to just lower the voltage which would have a drastic decrease in temps and fan noise.
No exaggeration when I say I have purchased over 20 minisforum systems. I have built two Proxmox clusters with the 3 X MS-01 and now I have 3 MS-A2s and UM780, UM890, AtomMan G7pt and several more and I only ever had a problem with one of them, returned it to Amazon and ordered another which works just fine. I only buy them from Amazon, to have at least 30 day window to return. I know my anecdotal experience does not represent the entirety of all purchased Minisforum systems. One thing to keep in mind is that these are reasonably complex systems where many of us are trying to do clustering, firewalls, etc. These are not normal end user practices and I realize that there is range of experience and aptitude in the technology hobbyist world.
I can also confirm I got an MS-A2 from Amazon. It nicely detected my 128GB of RAM (24h memtest without an error) as well as SSDs (newest BIOS). It was speedy and overall a really nice system. I just couldn't stand a high-pitched noise coming from the system fan, even at lower speeds. CPU fan had no such problem. Returned within the 14-day window (EU) and got a full refund.
What's funny is that the noise was really hard to catch on a video and some people couldn't even hear it in real life. Maybe it's some frequency that only certain % of population can hear ¯\_(ツ)_/¯ Even though the high-pitched noise is muffled (clipped? trimmed?) on the film, I put it on YT, so you can validate yourselves:
I'm very tempted to order a MS-S1 MAX for the more robust cooling, built-in power supply and all that. As neat as the MS-A2 form factor is the S1 looks a lot more practical. Spendy, but neat. It may wind up as my daily driver Windows box if I do rather than VM hosting. Kinda disappointed in the S1's Realtek NIC but dropping in a surplus X710-DA2 would fix that if it's a problem. Anyone buy both the A2 and S1 and can compare?
Acceptable tradeoff for me but good point. I'll stick with full-size machines when I want a high-power GPU. The S1 is a big step down from my Radeon 7900 but adequate and would free up a lot of desk space. Probably quieter than my current desktop too.
The upcoming MS-02 Ultra minisforum might meet your needs. It will support a dual-slot GPU. It seems that a low-profile RTX 4070 will be able to be installed.
