MAX6651
The MAX6651 is a sensor chip only for fan readout, this sensor chip is not automaticly detected by MBM because it has no device ID and it can be located on an adres which a normal sensor chip uses, so if I where to autodetect it many users would suddenly get this sensor chip in their fan list while they don't even have it
Edit the MBM 5.ini file and find the [ADVANCED] section, add the line MAX6651=1 this will make MBM scan for it.
Please understand that the fan dividor on this sensor chip counts for ALL fans and thus should be set the same for all the MAX6651's of 1 chip found. The last one MBM sets when starting up is the one that will overrule all others
example:
Fan 1 : MAX6651-1-1 : dividor 2
Fan 2 : MAX6651-1-1 : dividor 4
Fan 2 : MAX6651-1-1 : dividor 8
Fan 4 : MAX6651-1-1 : dividor 4
for all fans MBM will set the dividor to 4 since Fan 4 has it at 4.
