2nd Temp Probe?

[Lounge Lizard 6]

I have an old BE6. The wire probe measures the CPU temp. What does the 2nd temp reading indicate?

Ok, what is it typically on any mobo? (pretend we're not talking any particular brand :D )

The second probe is case temperature (ambient air temp in the case). This is used to gage how well overall case ventilation will be. You'll want to get it as close to room temperature as possible, this way you'll be giving your processor's hsf (heat-sink/fan) the best chance of working well.
The lower the case temp, the cooler the air supplied to the hsf.

Thanks. Is the 2nd probe just buried in the mobo to take the case temp?

Yes. On my Abit, it's very tiny and hidden around the system battery amongst a bunch of other tiny bits. It's usually mounted low and towards the front of the case so the cards and drives don't influence it's reading with their heat.
Your manual may point out it's location.
