This doesn't look like a hardware monitoring chip...

... which isn't all that surprising, as the LDN is 0x0e which is never
used for hardware monitoring features on SMSC Super-I/O chips. Most of
them use LDN 0x0a or 0x08. Only one model uses LDN 0x09.

So, Kessia, please provide the output of the following commands:

isadump -k 0x55 0x2e 0x2f 0xa
isadump -k 0x55 0x2e 0x2f 0x8
