I swapped SYS_FAN4 with SYS_FAN2 - fan connected to #2 is OK, and this connected to #4 is not monitored (runs full speed) even if it worked fine in #2 few seconds ago ... might it be a faulty MoBo?
Just to inform - turning off PSU (unplugging power cord should work too) for couple of hours fixed this issue.
