Summary0001669: Speedfan doesn't work proberly on Asrock P55 Deluxe ( IT8720F )

on my Mainboard Asrock P55 Deluxe the Fan Control with Speedfan doensn't work properly. This Mainboard has 5 fan connectors -> 3x 3Pin (PWR_FAN1 ; CHA_FAN2 ; CHA_FAN3) + 2x 4Pin (CHA_FAN1 ; CPU_FAN1). In the BIOS of the board CHA_FAN2;CHA_FAN3;CHA_FAN1;CPU_FAN1 are adjustable. CHA_FAN2-> Level1 to Level4; CHA_FAN3 -> "Full on" or Level1 to Level10; CHA_FAN1 -> "Full on" or Level1 to Level10; CPU_FAN1 -> "Full on" or Level1 to Level10. Within Windows the Asrock software OC Tuner can adjust these 4 fans without a problem. But with Speedfan its only possible to adjust CHA_FAN3. I only use 3pin fans (on CHA_FAN3 and CHA_FAN2) and they seem to work only on the 3pin connectors. I tried them on the 4pin connectors but they only work at full speed and aren't adjustable even not in BIOS. The fan speed display also doesnt work proberly. The only correct reading is the CHA_FAN3. The others sometime show nothing and sometimes weird values (even if there are no fans connected)

I uploaded the corresponding configfile for my Mainboard for the Asrock tool "OC Tuner". With this tool i'm able to correctly readout the fanspeeds and also i'm able to adjust the fanspeeds. Maybe this is helpful.

SpeedFan 4.43 should have fixed this issue.
