SG-1000 temperatures

[stephenw10]

If you upgrade to a recent snapshot you'll see that we removed the temperature reporting.

The value returned by the on board device is very inaccurate (+/- 10C) and it was causing far more concern than providing useful info. You can still read the value via the sysctl if required.

I will be pushing temperature limits on an SG-1000, is the status page now more accurate ?
Just testing some boundaries to establish if I need to add some heatsinking.

How do you intend to do that? It already has heatsink and the case is made like that so air flow is optimal.

I've found that removing / not-attaching the little rubber feet, and cable-strapping it down against a metal rack shelf, helps dissipate the heat a bit better.

In another location I have one sitting a couple of feet behind a server exhaust fan (which doesn't run hot) for additional airflow ;)

Glad this thing isn't PoE-powered! 5V is easier to cool than 48V.

Good tip :) You could add a small fan to it, just put it over the case grill and it will help too!

Pretty much along the same lines as I was thinking. moikerz
I have several installed remotely in small boxes, screwed to aluminium plates. The fan is the next option if heat proves to be too much.
The question is: How much heat is too much? I have generally had temps of 76 on the Status page.
Is there another method of measuring and logging temps?

[ivor]

Status page or command line will show temp. 76C is within acceptable range.

Don't try this at home, kids.

dev.am335x_scm.0.temperature: 51.0C

Cant' believe you didn't use a peltier heatsink. Geez..  ;)

Are you tellin' me this sucker is nuclear?
