+1 for mentioning 0xide. I love that they went this route and that stat is interesting. I hate the typical DC high RPM small fan whine.
I also hope that they do something 'smart' when they control the fan speed ;-)
- mkeeter 2y agoIt’s moderately smart - there’s a PID loop with per-component target temperatures, so it’s trying not to do more work than necessary. (source: I wrote it, and it’s all published at https://github.com/oxidecomputer/hubris/tree/master/task/thermal https://github.com/oxidecomputer/hubris/tree/master/task/the... ) We also worked with the fan vendor to get parts with a lower minimum RPM. The stock fans idle at about 5K RPM, and ours idle at 2K, which is already enough to keep the system cool under light loads.
- louwrentius 2y agoHa! thanks a lot for sharing, love it. Nice touch to use low idle RPM fans. Same thing for my ancient NAS: after boot, the fans run at idle for hours and the PID controller just doesn't have to do anything at all.
