For power saving settings I shamelessly recommend you read my initial post if you're going with Linux, which I assume.
Non-headless 7.2W are easy—and I've exactly the same setup (excluding memory) you're describing. 6W and less can be achieved by removing and downclocking hardware. ~3.5W if you're adventurous, but that'll be a setup primarily for idling, monitoring, cron-jobs. Write to memory (disk cache), you'r back up to ~4.2W; involve the NIC and it's ~4.5W; no DMA because you've to decrypt, ~5.4W. (Tip: power off cores it that's your use case (torrents, wsus, cache of sorts, backup destination)printf 0 >/sys/devices/system/cpu/cpu3/online
).
A bigger heatsink is not necessarily the better heatsink. Parameters are capacity (Cu is king), spread/conductivity (silver, heatpipes), dissipation (surface and airflow / geometry). The cooler which comes with the 3200G is good enough, imho, for what you're describing.
I've tested the Cryorig Cu and found that'll allow your machine to runlongerspiky loads without spinning up the fan—as expected, smoothing better. (I didn't test what most PC magazines go for, the top-end: Saturating it with heat.) But it's not worthwhile, given that the fan spins at its lowest RPM most of the time anyway, at least for me in server duty and office use, with the Wraith. (I've posted the fan-control settings here previously. Bump the lower temp from 55°C to 60°C, that's what I use now.)
I've toyed with a zero-rpm setup (page 25), but that too is not worthwhile. Once PBO is out (as it triggers the overvoltage bug;, but people don't seem to read my posts; I don't imagine PBO/PBC works anyway), the power saving settings and fan control settings are in (posts above), you cannot hear the thing like always. And when playing games, especially with a headset on, I don't care much about it.
(Running into fan spinups might be different with a 2400G or 3400G, which I didn't test. Whoever wanted mid-range or high performance should've saved the money and gone for a 3600–3800X imho. And whoever buys an Intel NUC these days either required by policy, loves the color, or is an illiterate bum who needs to subscribe to tech news in audio book format.)
The 12nm Zens are less picky when it comes to higher memory speed (3200 MT/s is 1600MHz btw.), and the higher the frequency the more W=€ are spent. On a homeserver, downclock for marginal gains. (And don't get distracted by the laymen measuring goodput of data access patterns mistaking it for memory bandwidth, which isMT/s× 8 byte× #channels
for DDR4 of course.) It's a revealing comedy like those “bicycle tyre rolling resistance” sites that strap wheels or vehicles to a motorized drum and claim “look ma, can do 60kph!!!”, and who drive the wheel instead of using the wheel to drive the drum. Digressing.
Thanks! I finally set it up this weekend. Used the following components:
- Ryzen 3 3200G
- Noctua NH-L9a-AM4
- Intel 660p 2 TB (*sigh* the 665p just released today...)
- G.SKILL Ripjaws DDR4-3000MHz CL16-18-18 1.20V 2x16GB
I disabled PBO and CPU boost in BIOS, as 4x3.6 GHz is just ideal for me. It doesn't make sense to vastly increase power consumption and heat generation to gain a few percent extra performance. Installed Arch Linux, enabled NVMe power saving as per your guide, and I'm idling at 8 W. The CPU fan is set up to spin at 800 RPM until 55 °C (it idles below 40 °C), and it indeed can't be heard at all, unless I put my ears next to it. I also ordered some magnetic dust filters, but they didn't arrive yet.
Now, to complete my setup, I need a basic UPS to protect from power spikes (and data loss caused by it). Does anyone know/use a SFF UPS? I'd just want like 5 minutes of runtime (initiate a shutdown after 2 minutes if power isn't back), so I don't need a huge, 500 VA UPS, which is bigger than the A300 itself. Ideally (for the best efficiency), the UPS would provide 19 V for the A300, instead of 230 V and going through the power brick... but that might require some DIY solution (which I'm not afraid of :-)). Honestly, the power brick is the only component that I could see easily failing. It doesn't seem to be a high quality one.
