tiger i7520SD (S5365) : no fan speed reading in BIOS

Hello,

I've a problem with my new tiger i7520SD motherboard: the BIOS seems
unable to detect my fans.
I've plugged 2 Nexus 12cm ultraquiet fan on the motherboard fan jumpers
(I've tried J16, J22, J5 and J18), but the BIOS fails detecting them.
The speed is "N/A". I've deactivated the smartfan, but the nexus fans
are still undetected.

i've plugged an old crappy fan (small and noisy): this one is detected
and the BIOS can read its speed.

Any idea where the problem comes from ?

And by the way, I'm also concerned by the temperature monitoring.
Currently, CPU1 temp is "33 C / 603 F", CPU2 temp is "28 C / 594 F",
System temp is "32 C / 89 F".
There is clearly a problem with the Fahrenheit part.


The BIOS is 1.01, the latest available.

thanks,
patpro
