Any way to find out CPU temperature on GoFlex Home?

This should ideally be posted on the PlugComputer forums, but I can't get myself registered there, so posting here in the hope that I will be forgiven :). I use Debian on a GoFlex Home. The device is being used in a production environment and running 24/7. I notice that the system seems to heat up quite a bit (though there is no SATA drive plugged in); it is however cooler than the SheevaPlug, which runs like an oven.

I would like to monitor temperature to discover if it's running at dangerous levels. However I can't get a clear idea of whether the GoFlex has temperature sensors on its board at all. In Debian, neither /sys nor /proc has any thermal zone folders. Does the GoFlex have a temperature sensor? If so, how might I access it from a Debian system?

Alternatively, has anyone seen their GoFlex suffer thermal damage?

I seriously doubt that it does. AFAIK, none of the Sheeva, Guru, Pogo or Dream plug have that feature, also not the Dockstar nor the GoFlex's.

OTOH, my Zyxel NSA320 does have a temp sensor, but that is a special chip/component.

• My Weather Station: (Pogoplug E02/Debianized 1-Wire Weather-Station/Cam)
• Linux 3.3.2 for Kirkwood Debian package
• Newer U-Boot for Pogoplug E01/E02, Dockstar, GoFlex Net/Home
• Rescue V2.8.1 for Pogoplug, Dockstar, GoFlex Net/Home, Zyxel NSA320 & many others
• Kirkwood Downloads (via my Dropbox public folder)
• davy's Github Repo's AFPDplug, SMBPlug, OWFSPlug, Cloudprint, Optware-DG, uBoot ...

My GoFlex Home is only warm to the touch. Even after streaming HD videos, it does not get hot at all. Perhaps room temperature or ventilation is a factor here?
