CPU temp with MBM5

Hi,

I recently installed new MoBo and CPU (AOpen MK33 + Athlon T-1.2GHz) and would like to know temperature of the MoBo and CPU. I notice that the MoBo have 2 thermal sensor slots but I cann't get hold of the thermal sensor right now. Anyway, I try install MBM5 and also other similar program. All of them report about 24C MoBo cpu (show up as Via686A-1 on MBM5). My questions is as follow:

1. Is the Via686A-1 is the MoBo temp? I tried look for the MoBo spec but it doesn't really confirm my understanding.

2. Other programs cannot report cpu temp (which it should be since I don't have any thermal sensor to measure CPU temp on my current MoBo), but the MBM5 report two other temps (Via686A-2 and Via686A-3). They are both at 77C!!? What are these reading? Are they just the reading of the unplugged thermal sensor?

3. I'm trying to get a thermal sensor. I found Asus have thermal sensor but it say that it is for slot 1 processor (I think it called P2T for mfg part number on Asus web site). I'm not sure if it will work on my MoBo (I believe it should work if the connector is the same and it should be the same principle, i.e., the same generic thermister is used to measure temp). Can anyone confirm my understanding or anyone tried using the Asus thermal sensor on other MoBo than Asus MoBo?

4. My CPU core voltage is at 1.76V. Is this normal for T-1.2G. It seem to be high for me.

Thanks.
