Where is the mobo temp. sensor located?
 

I have an Asus A7N8X non deluxe mobo.
My setup and pics: http://users.pandora.be/GiantKiller/PC

I placed two fans at the right side of my case next to my cpu.
(not on the pics)

Blowing air into the case gave : cpu 38°C mobo 35°C
I turned the fans so they pulled air out off the case.
That gave the following temps : cpu 31°C - mobo 41°C

The back of my case is open.

My question.
Where is the sensor located which reads out the temp. of my mobo ????
I know for the cpu there are two ways. One. a sensor under the cpu in the middle of the cpusocket. Two. reading out the cpu itself.

But the mobosensor ?

Does anyone know ?

some motherboards have 2 of them (mobo sensors)
one is placed in the close vicinity of the socket , the other at the bottom near the last PCI slots

You know why I asked this ?
In MBM 5 I've got MB:30°C CPU:37°C
In Asus Probe I've got MB:36°C CPU:30°C

I don't know which one I can believe.

Therefore I would like to know where the sensor of the mobo is located so I could put my finger on it for a little while so I could see which temp will go up. Then I know which one is the right one.

check the BIOS

some are also on die diodes in the northbridge.
