6.15.1 SIO Hardware Monitor HWM (J40, J41, J42, J49, J50, J233)
The Winbond 83627HFJ Super I/O Controller provides an internal Hardware Monitor. See detailed
description of used functions below.
Fan1 (J49) can be configured to run in +12V or +5V (default) mode with Jumper J233. The voltage of
Fan2is fixed to +12V.
Note1: To switch Fan2 in 5V mode it's necessary to remove R53 and mount on position R52 instead. See Appendix-B
Note2: Software resolution control of FAN1 is only working in 12V mode. If FAN1 is in 5V mode it can only be
switched on or off.

Connect thermal diodes via J40, J41 and J42 to the Winbond super I/O for external temperature
measurement. When using an ETXexpress module with legacy BIOS it's possible to control voltages and
temperatures connected to the internal Super I/O sensors in BIOS Setup or with 3
rd
party tools.
