Fan sensors displays wrong fan header (MSI P6N SLI Platinum)

mn12 · March 22, 2011

Hi, on my MB the fan speed readings stops when the rpm is lower than 380 this behavior is the same in all programs so this is a MB issue.

I use PWM to control my CPU-fan that can go below 400 (Scythe) and when it does AIDA64 takes the readings from the chassis fan and displays it as the CPU fan speed.

The first screenshot is AIDA, HWINFO32 and Speedfan and all 3 displays the 3 fan speeds correct (the polling interval is slightly off).

The second screenshot shows that when the RPM of the CPU fan drops below 380 and the MB reports RPM 0 AIDO takes FAN1 and displays it as the CPU fan.

In both pictures the chassis fan speed (FAN1) is constant at 430RPM.

Hardware:

MB: MSI P6N Platinum

CPU: Q6600

Fans: Scythe, Arctic Cooling and Silverstone

EDIT: I forgot the AIDA64 version: 1.20.1150

1) Please copy-paste the full content of the Computer / Sensor page of AIDA64 into this topic.

2) Then right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> ISA Sensor Dump. Copy-paste the full results into this topic.

3) Then right-click on the bottom status bar of AIDA64 main window --> Sensor Debug --> SMBus Dump (Full). Copy-paste the full results into this topic.

Thanks,
