After doing some research, i found out that Fujitsu's hardware mointoring solution inside the SCH5627 exports data thru registers 0xA0 - 0xA3 regarding the mapping between temperature sensors and fans. If those registers are set to 0, the fans are forced to full speed. The first patch adds support for pwmX_auto_channels_temp attributes to the hwmon core, while the second patch does extend the sch5627 driver. Both patches have been tested on a Fujitsu Esprimo P720.
