Summary0002635: Winbond/Nuvoton W83795 wrong detection on SUperMicro X8DTL
I'm trying to control 6 fans (2 cpu PWM fans and 4 e-pin fans) on Winbond/Nuvotron W83795G on SMBus. It's a server MB with minimal fan control via BIOS... Fans are at very high speed with very low temperatures.
SF see the fans, but cannot control them. Speedfan seems to control only some other fans at 0 rpm on ISA bus.
When speefan starts, there are some errors:

Win9x:NO 64Bit:YES GiveIO:NO SpeedFan:YES

Moreover, IPMI fan speed readings are wrongs in any software (I don't know if it can be useful, maybe a conflict?)
In attachment, SF, HWMonitor, IPMIUtils and AIDA64 reports

I think report id 0001911 can be related to this.

Thank You for your help.

Don't forget to update your IPMI firmware (it's 3.13 for your board).

You might want to look into ipmi utilities. Even the non-supermicro utils have a hard time controlling these options.

Look here:

Of course this will not help much if your fans are screamers!
With the X8DT3-F I had to apply these ipmi settings after each boot. With smcipmitool you could make a batch file.
