Re: [Soekris] net6501-50 normal working temperature
@David: I am, in fact, running OpenBSD (5.4-stable, was on -current for a while) and using sysctl hw.sensors to check the temperature. I am not aware of the problem you are talking about, but then again - 6 months ago I didn't have a Soekris box. However, based on the other answers on the thread I'm thinking that the measured value is correct. Best regards, Nikola Gyurov On Tue, Dec 3, 2013 at 12:36 AM, David Ruggiero thatseattle...@gmail.com wrote: Just out of curiosity, what is everyone using to measure the core temp? As I recall, OpenBSD 5.x provides (via /sbin/sysctl hw.sensors ) an un-compensated value that's actually 10 degrees C higher than the real core temperature for these types of Atoms. Or so folks seemed to think on this list about six months back. But perhaps you're using other tools or OSes that are already fixed...? My 6501-60 was running at 70C (compensated, actual) or better even under a very light load, using the standard Soekris case. I didn't like this, so I went the active-cooling route and drilled a bunch of holes in the top, right over the heat sink, and then put a very slow-speed, very quiet fan right under them, tied to the 12v fan header. I now run at a cool 45-50C (compensated) depending on the ambient temp, and pull only about (IIRC) 2W more at the wall, with no more apparent noise.
