This is what HardOCP has to say about the thermal protection on the ASUS A7V-266-E motherboard:
<< Something Asus did bring to the table with this board is the CPU temperature monitoring feature. Before you get excited, while this is a great feature, this does not monitor the on-die diode now present in Palomino cores. Instead, it uses the much more familiar diode placed in the bottom of the CPU socket. >>
Now I don't consider Kyle's site to be the ultimate authority in matters beyond comparing Detonator drivers on GF3 cards, but I think they are correct in this issue
