Hmm,

I'm afraid I cannot find any reasonable mapping between the BIOS readings and 
the sensors readings using well known multipliers. So I'm afraid I cannot help you.

The BIOS only sees 2 fans too, so I guess the 3th connector simply isn't hooked 
up to the chip (which is a pitty, as the chip does have the capability to 
monitor more then 2 fans). Also the CPU reading indeed is wrong. Probably the 
BIOS hasn't configured the sensor type correctly. You could go and see if there 
is a BIOS update for this, esp since the reading in the BIOS itself is clearly 
wrong too.

As for the mapping, you could try sending MSI a polite mail asking which 
voltages are hooked up to which pins and what dividers they are using.
