Sorry to wander off-topic, but is that a ceramic heatsink?

@gprovostHit up the local computer mall for a replacement power supply. Closest they had was 12v 10A to barrel, and then a barrel to 4-pin adapter. Anyways, everything checked out correctly, and no more errors. Thanks!

Well, if you wanted to go minimalist, you could probably solder pin headers to J13 and then hang an esp8266 off it using something like the esp-link firmware Edit: sorry, was thinking of the Helios4. The Helios64 would use P14 and it's already populated, so no soldering required. Then you'd just need to pick up vcc/gnd from the gpio connector to power the device. *note: I haven't actually tried this

In Hong Kong. Thanks!

Since the original (Helios4) is EOL and the new Helios64 is backordered waiting for a second production run, I know the odds are low, but.. do you have any (bare board or full kit) available for replacement/purchase/whatever? After it being rock solid for so long, I kinda redesigned my network around centralized storage and it's a bit of a pain atm. Thanks

with all the drives removed, I get: 5v reads 5.05v 12v reads 12.10v with 2 drives on one connector, the remaining connector reads: 5v reads 5.05v 12v fluctuates between 10.3 & 11.9v

armbianmonitor -u: http://ix.io/2Lae Did an apt update/upgrade & reboot today, and the system came back up but none of the drives did. Imaged a new SD card with stock armbian, and still no luck. Measured the voltage of the PS (at the plug, not the molex connector) at 12.3v Anything else I can check/try?

The problem is that the holes don't leave enough clearance to rotate those (at least on mine), so I just went with slightly longer screws and washers/bushings

I'm pretty sure you don't actually want the fan flat, as there's nowhere for the air to go then. I ended making some little 2mm bushings and swapping out for longer screws. I need to source a better fan still.

I have a style-A case on my R2S, and the device idles at ~50c. It works better if you can slightly shim the fan up away from the case, as their design has the fan blowing directly against a flat metal heatsink with no exit route for the air. I'd note that that tiny fan is very noisy.

Numbers look not far from where I am now. R2S says 64c, Cheap IR thermometer on the underside of the PCB gives me 48-50c, thumb says "ouch", and I can't get a reliable reading off the heatsink. Temp here is 30c ambient

Looks it's reacting correctly compared to the settings it's being fed. james@r2s:~$ cat /etc/default/cpufrequtils ENABLE=true MIN_SPEED=600000 MAX_SPEED=1390000 GOVERNOR=ondemand james@r2s:~$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor ondemand ondemand ondemand ondemand

Idle temps drop by ~10c without the enclosure. No issues with connections between the heatsink and the cpu.

I'm seeing similar results on my unit, although mine throttled a bit further (816 MHz @15 minutes) if you leave it running. In that little case with token ventilation holes, there's just nowhere for the heat to go. I'll retest tonight without the case.

My mistake. I saw messages about an updated driver but thought it hadn't made it into the releases yet.
