Hi,
looking inside my 712, I noticed that it has a thermocouple or somthing to dectect the temperature in the case. Tracing back the wires finds that they connect to the mainboard, and on the same connector, theres 2 wires that goto the power supply. I'd assume this is for a secondry fan?
Anyway, since it goes to the mainboard, does this mean its posible to find out the temperature in software? Since, if it was purley for fan control, it would be done in hardware, wouldn't it?

Thanks

According to the manual, the fan shifts ito higher gear, once the temperature exceeds 30 deg. celsius.

THAT would be interesting.

Caveat: I'm a SW engineer and this is from memory.

The fan speed is *generally* controlled by HW with PDC just setting the "ramp" in HW registers. Some servers might "expose" the temperature reading. I doubt the 712 does.
