Another short wierd "by the way"-story :

Since I changed my Q6600 to my QX9650 the Bios was never been able to show me the correct CPU-Temp ... no matter which Bios-version !
The CPU-Temp was about 5-11°C - although the core-temps seem to be correct.
I consulted the ASUS-Support a few times and every now and then the support-team sent me some Bios-files ... some official, some not... no matter - it did not change a thing.
I upgraded & I downgraded the BIOS - no change.

But now to the wierd thing :
Yesterday I downgraded the BIOS to 0904 ( from 1004 ) the third or forth time ... and suddenly my CPU-Temp is correct displayed !
This seems to be totally illogical to me `cause I had this BIOS a number of times ....
