High motherboard temp?- K9AG Neo2-Digital

[mhowie]

I just build a new machine with an MSI K9AG Neo2-Digital board, a "Black
Edition" AMD 64 X2 5000+, 2GB Corsair RAM...

I have a concern, perhaps unfounded, with the motherboard/mainboard
temperature being reported by MSI PC Alert 4, PC Wizard 2008, and
Speed Fan programs.

My CPU temp is <40*C, even at full load (Prime95), and is presented as
such by both the aforementioned programs as well as within my BIOS.
However, the motherboard temp in PC Wizard 2008 (called "System" temp with PC Alert 4
or "Temp 2" within SpeedFan) is being reported as between 85* and
100*C.

My machine hasn't shut down as of yet so I don't know if the
motherboard temp being reported is truly accurate or perhaps the temp is
accurate (seems to be as several different programs report it) but is
being pulled from a sensor or spot on the board which a temperature
this high should be expected (i.e., not a true representation of the "motherboard" temp)?

Any insight as to what might be happening here?

Thanks for the help,

You are using the wrong reading for mobo temp, or (unlikely) it's being reported in degrees F.

Speedfan and similar programs are well known for not getting it right. try going into the settings and find the proper temps yourself. If the BIOS reports mobo/case/ambient temp, use that as a reference. Idling in Windows, it should be within a few degrees of that value. Then load the CPU, and the CPU temp should shoot up, while the case temp may rise just a few degrees.

Unfortunately the BIOS only reports CPU and case temps (<40*C and <30*C respectively in the BIOS). I don't know what those programs are using for their motherboard temp, but they all seem to be drawing from the same spot on this motherboard.

You are right on about SpeedFan and similar programs being inaccurate. They report my power supply 12V voltage output as 6.2V. Fortunately, the BIOS does report this and the Antec power supply is providing just over 12V consistently.

Thanks,
